Alright here it is. I've been waiting for this since I saw your comment on another video. Thanks Derek, time to watch.

Most impressive to me is that each channel is so close, to spot-on watts equally. I'd never run it to max, so the THD would be a lot lower at reasonable listening levels.

I like that you test all types of amps.

@@tarstarkusz that's just great.

Fantastic overview of this little amp. Really appreciate your attention to detail and on camera presence

the included PSU is 32V @ 3A, or 96watts, so the fact that you could get close to 150watts out of it before the overcurrent limit kicks in is pretty impressive. I also expect there was some sag in it's output voltage at that power level as well. I bet if you ran at 70W/ch you'd see the brick get very hot, and probably shutdown on thermal at some point. at 32V input to get 320Watts out you'd need 10A input.

I have the last generation of this amp(silver one) and it's made it into multiple boom box projects of mine simply by virtue of it being so versatile. I had the same issue with a small bit of black noise with the supplied power brick, but when I hooked it to a 24 v werker sealed lead acid battery, noise went away. Thanks for the video man, these amps are a great diy bargain.

I know this is an older video. But, just wanted to say "thanks" for doing what you do. I have learned a TON from watching your videos and learning how to get the most out of my chip-amp DIY ammo can speaker builds. 😎

I bought this about a month ago and I couldn't be more happy with the quality of both the sound and build quality. I would highly recommend to anyone who enjoys listening to music.

Thank you. I've been interested in getting one (or one like this with a sub output), for a computer system, and have been keeping an eye out on all the mini gear you review.

Great work man! I am setting up my own home automation, and I am in the market for some small stand-alone amps to use with a Google Chromecast and HomeAssistant. Looks like this is just the ticket! - Love your videos! KEEP IT UP!

In amps for sale in the EU, the binding posts are not allowed to be spaced according to the spacing required for dual banana plugs, because some European power cords with round pins use exactly the same spacing, and the profoundly efficient rule-makers in the EU government don't want people getting the two confused with each other. So even most new high-end amplifiers don't use the standard spacing.

I had one of these in my living room and it is an awesome deal for the money... Lepai, Breeze Audio, Nobsound and Fx Audio use the same design and chips... These little amps love 4 ohm speakers and they get LOUD...Sound quality is pretty good, mids and highs are awesome, and the bass is acceptable(yes it can slam, but it doesn't really have a great controll of the speaker when it starts playing lower than 40-35hz as you need really big capacitors(power reserves) for that)...Honestly it can easly replace 95% of the low to mid end hifi amps/receivers... Now i use JVC-RS33(class A) which is one of the most powerfull receivers of that time and it doesn't get that loud but it has a little more dynamics( but ofc it is like 20 times bigger and it weights 12kg)

Awesome video looking foward to the next one!!

Enjoying the channel! Would love to see a full test on the S.M.S.L. AD-18! It looks and sounds great, and it seems to produce all of the claimed 80 watts x2 @4 Ohms, but it would be good to see it run through its paces.

Another stellar job! Very informative! I was gonna bet that the amp wouldn't be able to do the advert specs even @ 10% distortion. Wow..one of the first Chinese Class D amps that was worth it's salt. I know you limited distortion to only 1%, pretty darn good. I would have liked to see the test w/the high power battery @ 8 ohms. No biggie. Always enjoy seeing amps tested in real life. Thanks again!

If you have a way to test thermals you should try OEM Vs. High Quality non-conductive Thermal Paste on the Amplifier Chip to see if any real gains could be made in the thermal department to more effectively dissipate heat into the Heat Sink since it is passively cooled.

Most of these amps I've seen that carry an external power transformer/rectifier package connection have cheaped out on the included ones. By the time you add the cost of a quality one in to reach the advertised power ratings, you reach the same cost as typical big-name amps with internal power guts.

I have the same click/knock upon pausing when my Android phone hooked on my semi truck. Most audible when radio is at higher volume. This is most likely caused by the BT radio transceiver going between drive and suspend modes.

Awesome vids. Can you review the 1Mii08?

75 WPC with the included power supply is actually pretty good. It's a tiny amp that could be velcro mounted to the back of one of a book shelf speaker in the pair. I have the Lepai LP-168HA 2.1 amp that I've been using on my pc for over 2 years now. It's held up very well and I'm planning on using this brand of amp for a couple "boom box" setups I'm going to build soon.

I have a similar sized amp from fosi audio that also includes a 100 watt subwoofer channel on top of the 2x50 watt stereo channels. It drives 2 dayton audio bookshelf speakers and a ct sounds bio 1.0 10 inch subwoofer

I'd be interested to see how that amp performs long term with the main heatsink mounted _inside_ the case with no ventilation or coupling to the outer aluminium case. Don't think the heastsink is gonna do much the way they have it mounted.

I was wondering when you would test another one of these. 😊

Thanks for review

Would it be good to run 4 of these as 7 channel surround and .1 go to powered sub. Would to audio be better than all in one 7.1 receiver?

Whole case can act like a heat sink. No Ventilation for the heat sink on the main chip inside the case. Priceless! I wouldn't expect to be pushing this amp to the max for any extended period of time.

I don't know why i got excited when it did over 100wpch, I have one of these, mine is a shure and it's sitting in a storage drawer lol, but still kinda cool to see

Yeah man can you do more home audio stuff??

nice video

Yeah, the PSU can output an absolute maximum (on paper) of 108w. It won't, or shouldn't, be a problem for music since you're not playing pink noise at maximum volume, and the likelihood is, the capacitors in the PSU will allow higher current/wattage bursts to handle the transients in music.

@MrSookonn

5 жыл бұрын

Psu is 96w and how can you measure thd with pink noise? Getting 2x76w from that with 1% thd is absurd.

This depends on the impedance of the speaker. Please explain to viewers what impedance is. Impedance is the opposition to alternating current. That is different to resistance, though both are measured in ohms

Is it possible that it pops because of it switching the speakers into a standby mode

Dont even care....I want one of these for my living room speakers. Im running some el cheapo vm audio powered tower speakers and lately the amp has developed some serious left channel bias. Can barely even hear the right channel. Gonna do an amp-ectomy and see if it doesnt fix my channel imbalance issue. Thanks a ton for reviewing this thing BigD!

The heat sink in one of the important part of operating an amp, and im glad coz aside from the heat sink inside the bottom of the amp serves as its heat sink to. Coz at first im wondering where the heat will exit coz there's no ventilation. If i own one i would upgrade a little like putting a hole or something for the heat to exit from its cabinet.

Good job Big D

These amps are almost always limited by the voltage and current available from the power supply. Also, power for these commodity chips is normally rated at 10% THD. Class-D chips tend to have very low THD up to a "knee" where the onset of clipping occurs, then they rise rapidly, but the benefit of this is that the 1% or 0.1% THD power output is not very much less than the rated power rating. Also, your speakers are usually generating much more THD than the amplifier, even at the amplifier's full rated power.

BigDWiz did you by chance ever bridge this thing? I was curious to know if it would react well to bridging at 8 ohms. I realize this is an old video, but I'm thinking about making a lil bluetooth speaker and figured you might know a bit about it

Hi, Can you bridge the speaker outputs for one full-power mono speaker? Thanks

That pop is do to the circuit system stoping noise feed back or hum for the Bluetooth speaker

Looks like the speaker output terminals could have been drilled on the back panel in a parallelogram configuration instead of a rectangular one and dual plugs could have been made to work.

so power supply it came with did not provide proper voltage? would an external more constant supply burn the unit?

LEE PAY :) Ok, so that is a neat little desktop amp. I'd like to see it run full tilt for a while and see how hot it gets.

chip looks like some form of tda from st micro, maybe a tda7498e. the paired pins down one side are a good indicator . little beast

Can u add a subwoofer to this amp? Thanks in advance!

Can you test the Buttkicker BKA 1000 N? Looking to use one for my home theater set up.

Does this have any noticeable noise with no signal applied? With the bluetooth capability this looks really tempting...

Could one purchase a 36V 3A plug in power supply and be fine running that instead of the provided power supply?

Hey Big D will you ever test the Crown XLS 2502 amp?

Chip looks like something similar to a TDA8920. Not much of a surprise to see it there. They seem to be the bog standard chip in a lot of newer class-D amps.

That front faceplate, toggle switches, LEDs and volume knob look the same as the ones on my FX-Audio DAC6 headphone amp. Aaah just saw the FX -Audio printing on the PCB so guess there the same company.

Can you please test out the Menace Audio and monoblock amps. I have 2 of them one is 3000 max 1000rms and a 6000 max 2000 rms

do you think it will hold enough time on 33v power supply ? it will get hot ? can it run for many hours at full volume on 100w per chanel ?

I can tell you one thing about these class T amps. I have bought and used maybe 10 in my family of different types and brands including a yamaha based board and they don't seem to last very long. All but one where chinese diy boards but one was an expensive designer amp. The big tripath chips have been the best as opposed to the surface mount amps. They work very well with vintage speakers designed for tubes.

I believe you are correct 👍

Hi ! thank you very much for the very interesting demo as always. Personally i would not overestimate the BT issues ... to get decent sound a dedicated receiver can be the best solution. And if wifi is available a Chromecast audio will be on another planete. I would how this amp would sound with a nice Meanwell smps (great quality usually) Moreover i think that not only voltage is important but also the ampere delivered by the power supply. That is very evident also for normal amps. Replacing a small mains transformer with a higher VA one with same voltage the sound comes alive more. At least this is my experience. I think that the power solution adopted can have a decisive impact on sound quality In the end the amp is like a tap ... if there is no enough "pressure" upstream the flow to the speakers will be scarce Kind regards, gino

Can you do a video on a Planet Audio 1500.1m? Would be super helpful! Thanks Big Wiz!!!

Big D Wiz You know I’m a frequent viewer and I truly like your channel & video’s although I truly doubt this thing does anywhere near 200-300 Watts. Also, Yes I’m responding before finishing the video because I will be truly dumbfounded if this tiny amp makes almost double the power of my Denon 5803 that is 10x the size of this and it makes 170 watts per channel. Also have you ever heard of the pioneer 1980 ? It is a silver face receiver from late 1970’s and it was like the king of power receivers with 270 watts per channel at less than 0.03 distortion. So I guess you already get where I’m going with this, why would these home receivers that cost $5000+ that are considered flagship put out less power than this tiny “pocket” sized amp ??? Maybe you know more about this than I do. Great video btw 👍

Wow that's not bad for a tiny little thing. 😮 How did you like the sound, BigD? Great video bro!! 👌

I have old ears and this little amp sounds good and surprisingly “full” for its little size and Class D topology

So, if more battery power is connected we can use it and it wont burn up?

Supplied power supply provides lower power which might extend it's life . Running it on higher voltage might very likely shorten it's life as it will run hotter . Also why not add some Vent holes simply remove the covers and drill a series of holes in the sides and top to allow air flow. Add some fine mesh inside to keep dust out . ( even if your not increasing the voltage ) In a small space this amp is plenty loud Dorm rooms for example you will not likely max it out . A musician friend uses one and finds it plenty for his small space.

I have a pair of Rogers Ls3 5a at 15 ohms , do you think that this amp can handle it ?
