It definitely livened things up a bit and made for a bigger larger soundstage. Having said that, I'm not sure it's worth the money tbh. For the $160 for the two discrete op amp chips and $80 for the A07 - at $240 you have a lot of other options out there would would probably sound better and give you more clean power.

This is super cool. Never knew how straightforward opamp changeout could be. Particularly cool that there are little risers to accommodate the space needs of the upgrade. Now I want to try this!

Randy, just wanted to say thanks for the advice the ss3602's do provide excellent clarity and separation from the originals that were installed. The over all installation was easy to perform and took about 5-6 mins. Keep up the great work as the cheapaudioman it is truly appreciated.

@cheapaudioman - I followed your guide & "rolled" the factory op amps for the Sparkos. It wasn't hard to do & my wife & I both wholeheartedly agree the sound is MUCH better! I also swapped out the factory power supply for the DROK 48v 10A so I cant be sure of the results but our SVS Ultra Bookshelfs are for sure louder as well. Thanks for the great content

Absolutely Randy. What’s old is becoming new again! So many little options on amps that got left behind for convenience sake are popping up again!

I still have my first Hi-Fi system that consist of a pair of Pioneer 3-Way speakers, that I bought used when I was in college, one of the original Lepai LP-2020A+ *Tripath* Class-D amp with an upgraded power supply, and a Pure Audio A2 Bluetooth receiver. The upgraded power supply reduced the distortion dramatically, even at lower volumes. I moved it to my office and I enjoy it every day, mostly for listening to music.

I want to stop and take a quick second to say thank you for all this awesome information you are putting out for people like myself who just don't have the experience or knowledge in audio equipment and components in general such as yourself. I am learning so much from you and gleaning everything I can and I really do appreciate your content so I figured the very least I could do is let you know. So thanks man.. I really appreciate what you do. Keep up the good work.. Lock in another new fan and subscriber from southwestern Indiana.. Peace and love to all.. Joseph M Hodges

You're an inspiration you know that 👍I was fretting over what tools to use to change op-amps, scared of damaging something - and then I see you using fingers and knives - and thought what the heck - went ahead and did the same - and am all set 😃 thanks for this Randy

I started off not liking you and almost turned off the first video I saw from you, you are now probably my primary channel for audio equipment content. I appreciate your show and hope you continue to grow. Nice job!

I have the Sparkos ss-3602's inside my HP amp (Gustard H20) and they're very good sounding pieces. I am also trying out the Burson v6 Vivids in comparison and they're great too (but in my amp the Sparkos are slightly better - in another component it may be the exact opposite). This is a relatively cheap mod to upgrade SQ on any component that has compatible opamps and DIP8 sockets - much cheaper than buying a different component and most discrete opamps stomp IC opamps, IMO. Be careful to make sure which types of opamps are inside of your component before you replace them - ie: single or duals, opamp inter-compatibility, and orientation. Happy listening...

I upgraded my 1984 Denon DCD 1500 II CD player with Texas Instruments op amps. The sound quality improvement was even greater than the new DAC & new capacitors. I now have a magnificent Audiofool quality CD player that started out as a $5.00 thrift store score.

Thank you for your educational videos, super helpful reviews, and introduction to audio space. I actually bought the amp and the op amps. Hooked it up to some LS50’s I bought for half off. The system sounds fantastic. This is coming from a guy who loves McIntosh and vintage tube Marantz. Great fun!

I recently viewed your video about the $80 Amp and decided to give one a try. I would like to thank you for the info you provided, here is a copy of the review I left about the Neoteck Bluetooth 5.0 Stereo amp. I purchased. Title: The surprise was on me! I purchased this amp for my home office as an experiment, well the surprise was on me. I never expected that this little amp would perform so well. I hooked it up to my Polk S60 towers, this little amp powered them surprisingly well. I then hooked it up to a pair of Energy Connoisseur C3 book-shelf speakers I had stored away and what a surprise I got. The Neoteck Bluetooth 5.0 Stereo amp was where it is supposed to be. I had planned to sell these speakers, I've had a complete change of heart! This little amp breathed new life into them, I had forgotten just how good these speakers could sound. The Neoteck Bluetooth 5.0 Stereo amp punches well above it's weight class. I spent 1 1/2 days listening to all types of music on this combination and I'm still amazed with the sound quality. I highly recommend the Neoteck Bluetooth 5.0 Stereo amp for a small room or office, you will not be disappointed!

You can push the pins on your old op amps into foam packing to keep them from bending further. Then put in bag.

Hey Randy.........Thanks a ton for this.....Just got mine in today and have yet to fool with the op amps.(oh..it will happen) But over all, I am super impressed with just the stock sound! Best 100 bucks I have ever invested in this wacky love.

I remember upgrading the $0.50 op-amp in my old Creative labs 2:1 sound system with a OPA2227 many years ago. Certainly made a difference. Not really had the ability to do it again since.

Love the diy videos! I’m cheep as well and enjoy building and improving My audio stuff as much as I do listening to it. Keep up the good work!

Did it! Installed yesterday... Love it! Excellent Upgrade... Thanks Randy!

Hey gang....just to let you know, I installed these Sparkos op-amps in my Aiyima A08 also (now do be advised though that the A08 takes 3 of them), and again - a major sound change for the better ensued! The amp now (also) has that class AB sound - that is warmer and more dynamic. Now do be advised that with the A08, it's a bit more tricky. The top does NOT come off. Remove only the front panel (where you'll see the 3 op-amps right towards the front for easy access), unscrew the 4 screws, pull off the volume knob, and unscrew the nut that holds the volume knob control ring in place tightly. Then you pull off the front (it won't come all the way off because wires are attached). Now, reach in carefully and remove the stock 3 op-amps (use tweezers - they work the best), and then you just replace them with the Sparkos ones. At first, I tried taking off the entire top - can't be done, and you have to be very careful because you could damage the unit. Again though - it's another wonderful upgrade, bringing the A08 to amplifier audio levels that usually you'd have to pay 10 times as much for, or more. Enough said! Thanks again to Randy for making us aware of upgrades like this.

Great idea of Op Amp rolling. The idea of tube rolling is to introduce more or less distortion to the audio signal. Let do it with op amp as tubes are getting more expensive.

@RaveyDavey

2 жыл бұрын

No the idea of tube rolling isn't to reduce distortion. It's to randomly swap in other tubes (normally more expensive "vintage" ones) and see if you prefer the sound afterwards. Tube amps usually have high distortion full stop. It's probably the main reason some people like them. Likewise, without testing, you've no idea if swapping a chip in will reduce distortion or increase, or mess up the rest of the circuit.

Randy is the BEST! So glad to be able to support his fabulous channel. It just keeps getting better and better!

Respect for such a well used knife! Knives are great!

An operational amplifier contains 20 transistors. A transistor can replace a single tube. The operational amplifier is a complete amplifier circuit consisting of many transistors and the ability to control many features of an amplifier.

Im glad i found this channel,,, beginning my Audiophile journey

i bit the bullet and bought the risers and chips for my ayima a07. for me, even with equalization which did improve the sound, with some rockish-songs my stock a07(paired with a AYIMA T8 PREAMP) running to DUAL polk subs paired to tsi-100s just had a 'missing middle' and slightly hissy highs and maybe bass that was disconnected in an odd way. i tweaked and tweaked and got it sounding good but was still a little unsatisfied. the sparkos do make a very noticeable difference and to me improvements. separation is definitely increased...just more space and depth to all forms of music. and that 'missing 'middle' that i was experiencing has been fixed. much more balanced sound and seamless sound now. i wasnt sure about these but i am much happier about turning the system on now and listening to music.

Would I believe it? Sure, with measurements to back it up. Sighted, non-level matched A/B tests are so prone to expectation bias, if the difference is as big as you say it will show up in measurements - the Aiyima A07 stock is a decent bang-for-buck TI3255 amplifier, but has clear shortcomings when you don't factor in price as much.

If anyone is worried about damaging or losing the original op amp, these can always be purchased for likely under five dollars from online supply stores, like Digi-Key and Mouser.

Full size amps from the major manufacturers all have op-amps too, in their preamps, as do DACs and CD players, any source with an analog output stage, unless it's a full tube component, like a tube preamp, power amp, or integrated amp.

Hehe I’ve delved into op amp rolling, and tubes, and pads, it’s all very subtle, BUT, it verks 🤷🏼‍♂️ tubing has been my favorite

i actually just came to this realization right now but it makes perfect sense. you gotta realize that when they make chips they make thousands or even a million of them. then they are going to test them and purchasers who buy large quantities will have more say in getting quality, that is meeting the parameters. because there is variability, inside of a chip especially an op amp there could be dozens of resistors, and those are all going to have variability. also resistance varies with temperature, and chips can get hot. by having discrete layouts, you're spacing out that circuit and letting the components stay cool, also you can try and select higher quality or even tune the circuit the way you want it based on the component values. also that's called a DIP socket not an op amp receiver

Great video, especially for people who realize the benefit of something like this. Having built or repaired computers, laptops, and smart phones, this looks no harder than swapping out memory in a computer. You just have to make sure you plug it in the right way as computer memory is slotted to not allow you to insert it the wrong way. Laptops aren't fun to work on and smartphones just plain suc I'm to try and repair. Would this work with the Aiyima A300? If so, would it be the same chip based off amp that the A07 uses or would it be a different chip? I can probably figure it out in a few Google searches but obviously you would know, or figure out way quicker than I could. Also, thanks for all your tips in various other videos. I was looking for some bookshelf speakers. While I wasn't planning to spend what I did on the Elac Uni 2 B52's, I'm glad I did and I've only had them for 9 or 10 days so still breaking them in. They didn't amaze me out of the box but they have been getting better every day. Vocals are crisp and clear. It's just balanced as you stated over and over in various videos. I'm not sure why people think speaker break in isn't real. Think about it, popular materials for speaker cones are paper, metal, plastic, and aramid fiber. Plastic is obviously going to stretch out a bit over time. Paper has more variables. Aluminum is woven very tightly so it will stretch a bit over time. I don't believe I've had a speaker that uses aramid fiber. Personally, I believe speaker manufacturers make the woven cone material slightly tighter than it should be for this very reason. I also have the Sony HT-A7000 and initially I was going to return it. Out of the box. I wasn't amazed. Then Sony announced new rears which are 2 smaller A9'S that run on battery for 10 hours (per Sony) and they are bringing the same software used in the A9's. Initially I didn't get a great Atmos effect but I swear, one day it's like it turned into a completely different sounding speaker. All the sudden I was hearing sounds that were coming 4ft behind my head. A wall is 1 door away so that was new. Anyway, it wasn't great for music, which is why I got the Elac's, Aiyima A300 and the iFi signature one, mainly because it had the right inputs/outputs I needed for my setup. Now I can hook the optical out from my TV to the iFi and with some tinkering around with time delays, get everything to synch up perfectly so it's the best of both worlds for movies. Music is just Elac's. I do wish the wireless Sony subwoofer did have an input but I will just get sub down the line.

Thanks for another great presentation! Any thoughts on starting with the power upgrade first? This could not only give more power but might also improve the sound.

You remain! THE Chief of cheap. Awesome video. Keep up the qualdee videos Chief.

I love your chip extractor tool!

Great idea for a channel man love it

I got Burr Brown OPA2134 in my Aiyima A04. That tightens thins up. I'd invest in an upgraded heatsink before driving it with anything over 32 Volts...

That's a good "classic" opamp that trounces the normal but old ne5532's. The 2134's are quite a bit more refined vs the 5532's used in most budget gears.

OPA1656 vs OPA2134? 🤔

@@RAW_Reality I wonder that too, though I don't know much about the 1656...

Nice video, like the idea of doing this! Pleases my inner electronics child. To be honest, they could just have encased everything in the same dip package and it would sound just the same, and would no longer look discreet. Op amps matter in many cases, had my fair share of that during my thesis. Different frequencies though (few 100kHz)...

I got the OPA1656 (Burr Brown) op amp for my AO7. I looked into the Sparkos op amps while researching and found the OPA1656 to be almost identical in claimed specs. only the OPA1656 is $15 and Sparkos are $80. And they sound way better than the ones that come with the A07.

John, how would you describe the improvement you heard with the OPA1656 Burr Brown op amp?

@@naastradamus I got an A07 this week, and have some OPA 1656 coming next week. So far the A07 seems very nice, but it's hard to do a direct A/B without an amp switcher. I'm also using a mid to lower level 12 year old Denon AVR as a baseline, so I don't have anything really nice to compare too. The soundstage seems good as it is now. Whereever I may roam at 14s comes almost behind me.

I’ve got OPA1656 chips in an A07 and a Tube A3 preamp. They’re a great deal for $15-20 and imo the best bang for the buck.

@@vanoverbay774 Looking forward to your feedback as long as you have the exact same setup than me... and I wonder how big the difference would be

Intrigued by a new product from Orchid Audio which converts Single ended to balanced. Cd be useful for something like a Saga + or other SE pre amp

An a07 with a pair of Burson v6 vivid opamps and a Burson supercharger is hilariously good. swapped all the stuff over from a funk and it almost the same amp but with more power....but it's also $500 in upgrades on a $65 amp lol.

yes one can have great sound stuff with a bit of learning how stuff works my favorite thing is the Equalizer.and as internal parts op amp upgrades and capacitors nichicon capacitors i love thaty brand and Audio gold are very nice low esr just nice units

Yes, a little bit of research and patience pays off. Nichicon KZ and Elna Silmic II are the best audio electrolytic capacitors, and if you bypass them with a C0G Ceramic capacitor they sound even better.

@@overbuiltautomotive1299 Ideally it would be Film Poly Caps, but there is no space for those inside the Aiyima, so the next best thing is the C0G or NP0 Ceramics , brands like Murata or TDK. Use aprox 1% of the capacitor capacitance you want to bypass

I love upgrade hacks like this!

Randy, first of all I want to thank you for all your advise. Now I am much more informed about audio! I know my question is not related with this post topic, so sorry. In my room I have an old Denon AVR-3805 receiver paired with 2 Infinity TSS 1100 bookshelves as rear speakers, 2 Definitive Promonitor 1000 as front speakers, one Definitive Procenter 2000 as center channel and a TSS 1100 Infinity subwoofer. I am impressed with all the good comments that the Sony SS-SC5 speakers get. I am wondering if my setup will benefit if I replace some of my speakers with the Sony speakers. I am thinking to replace the Infinity with the Definitive and then the Definitive with the Sony. What do you think? Thank you again for all your effort and for your answer in anticipation. Best regards.

I would love to see a comparison video down the road that did actually compare this to a 1000 dollar amp just for shits and giggles. Truly enjoy your channel. We know you have one :)

Sweet! Nice diversity in your coverage

Hey, great video. Do you think upgrading the power supply and chip in the aiyima d03 is be worth it?

"It sounds like a more expensive amplifier." - because it now is :)) The two little op-amp circuits more than _triple_ the cost of the A07. For some, that might totally be worth it. For me? I'm not so sure. I'd probably have to get better speakers first to even hear the difference... Cool little project either way :)

Hi my friend, you are the cheap audio man, and it would be a amazing thing if you compare different op amps in this device. There are so many cheaper options as the recommended discrete op amp, also a lot of IC op amps would boost the sound in a great way. I am sure many people would like to see what you think about the OPA1656 or LM4562 and also the MUSES8832E for example. I personally would really love to see it. Thanks for your really great content!

Yeah for example OPA2134PA are much better for a lot less money

In the late 70s-80s, TIMD was still rampant, and many amps, equalizers, etc, used op-amps like the 741 (Yikes! Argh .....0.7 V/u-sec!). So, a standard practice was to replace them with 5534s (12 V/u-sec = no TIMD).

From one model to another or from one manufacturer to another, the very same part number Op-Amp may be in circuits that are somewhat different in the way that the signal input and output are handled electrically. A replacement modification like this may or may not act in the same way electrically. Also, stacking a chip socket into onboard chip socket will subtly change the loading on the signal inputs and outputs of the circuit by lengthening the signal pathway. This may or may not cause issues. Also, the dual stack of the discrete Op-Amp replacement and the additional chip socket has raised it up above a well designed circuit board with signal traces and ground planes that minimizes interference from other components in the power amp. Basically, from one piece of equipment to the next, swapping Op-Amps with another model number or with a mini discrete piece like in the video can result in better sound, no apparent change or maybe even sounding worse than the original chips. YMMV

Thank you very much for this information.
