hi, if you want to learn about les paul guitars there is a great youtube video on five watt world "the gibson les paul- a short history". enjoy your quest!

Thanks again for the killer info! Love this guy!

I have been watching your videos on my KZread subscription for over a year. Great to hear some truth about audio. I live in Upstate SC. I have been looking for a TAD distributor. I grew up in Japan in the late '60s and 70's. I was fortunate to be shown the difference between consumer electronics manufactured faster and cheaper for the masses; and audiophile grade components assembled from high-grade, audio specific electronics. Thanks for exposing some of the BS. Also thanks for all the great advice.

Happy Holidays Mikey! I’m a 66 retired hifi guy. My wife of 43 years both enjoy your show. Back in the 70s hifi was so popular. It’s definitely not so much now. I attempt to introduce young people to hifi. Most of the time if I say hifi or audiophile they have no idea what I’m saying. Once they hear my very sub 20k kit there shocked. I have a few young guys who have started there journey in hifi. We need a mentor program. I was shopping for speakers recently but couldn’t find anywhere to hear them within 3 hours drive. I don’t know what the answer is but the industry needs a jump start. Happy new year buddy!

Hi Mike! What can you say about Enleum Amp-23R Desktop Headphone and Speaker Amp. "VERY HIGH-END sound, from a VERY SMALL design", weight just 8.8 lbs and cost $6,250? Is JEFF ROWLAND - MODEL 125 better?

There are many online high praised reviews of GAN fet amplifiers made recently like Orchard Starkrimson Ultra 2.0, Peachtree GaN400, Voyager GAN 350 by LSA, AGD Tempo di GaN, Audion or Vivace, Java Single Shot or even Atma-Sphere. Could you please put some thoughts about them? Thx.

For Class D under the price of AGD Tempo, I choose silicon based Class D Designs like the Jeff Rowland 125.

Another great MAS video, Mikey!

My go-to path going forward, in light of your sage advice, is to consult with you first and then do an EMI/RFI noise check on any product coming into my rig. If it’s noisy, then I’ll promptly return it to the vendor or dealer with a note of shame attached.

How did your client discovered his Class D power amp’s power supply might be an issue? I’d imagine that such power supplies are a likely source of added EMI noise in one’s rig. You should devote one of your MAS to the importance of minimizing EMI/RFI noise in one's rig.

@user-xg6zz8qs3q

I scratch my head at this statement. Class D chip amps are inherently designed to filter out noise through negative feedback loops. The head designer of Hypex modules claimed that he solved noise a long time ago in an interview through circuit design. This shouldn't be a topic in 2023. And if we're still here it could mean a lot of things. Perhaps negative feedback loops add some artifacts in the original sound wave. Measurements don't show that because people only test for sine waves (not complex music).

Hi Mikey, I understand that the audio designed amplifier boards are available "naked", and that's the way I would want them. The amp board built into the vacuum tube is cool looking, but can it be taken apart? How would you ever recap those boards if it can't come out of that glass envelope? Or is it designed as an appliance....once it stops working, it's done?

I have no idea what you mean "naked" .. you are a DIY Kit guy ?? 99% of buyers dont want to sling solder. Yes, the tubes can be opened and repaired on a component level, but an end user never needs to be worried about that. AGD will just send them a new tube.. AND its impossible to "Blow" these tubes, duty life is 30 years 24 hours a day 7 days a week, and they cant blow speakers either..

@@OCDHIFiGuy it's not a basic thing they do. Everything they do inside the technics su-r1000 is proprietary designs. They only use pwm at the end for digital to analog conversion. Feedback is done before that. And in the digital domain. Even the clock is put right beside the pwm output stage, less than a cm away for shortest possible connection. As a engineer myself. I find the technics su-r1000 to a bit of a masterpiece and a great value for a all in one solution. I haven't tried any better one box solution. And I've been through MANY! So many it's not even funny. And many of them costing 5 to 10 times as much. So something must be done better in the technics su-r1000 compared to all the other way over priced and hyped pieces of audio gear... Nothing wrong with using pwm at the output if you know how to do it.. If you have any advise for a one box solution I should try. Let me know. I will do my best to get my hands on it.

@@OCDHIFiGuy Luckily Technics doesn't really make anything for the home theater market so you will have to stick with Marantz. But likely as the only guy here who owns both the Technics SU-R1000 AND the ADG Audion Mkiii's I can tell you that the Technics is a masterclass in integrated amplifier design. As an amplifier only, I give the AGDs a small edge but it's nothing earthshattering. And it's $7,800 for just the amps, you are not getting the preamp, DAC or phono stage that complete the Technics package. And they do some things that no one else is doing. Not sure if you are picking on the "baby" Technics (which I have also had in my system for about a month) but if you are you are barking up the wrong tree.

Said creator responded to my comment with a link to an eval board from GAN Systems, which I can only assume he meant as a rebuttal to AGD's claim (repeated in the review video that cheesed him) that they use the only GaN FET technology purpose-built for audio.

I have more thoughts rushing through my head since yesterday. I can't deny anything you said in the video. I am just offering my frugal internet shopper perspective. Scrappers don't use such poor EVAL boards. Scrappers buy amplifier modules like the ICEpower 50ASX2 board for about $140. They seem to be built well, and they measure well (the only thing that matters these days, but I'm cynical). The EVAL board in the video looks so cheap and flimsy, it's not representative. Regardless, the proof is in the listening. I would kill for a comparison between a scrapper amp with a Hypex module and a "Hi-Fi" amp costing thousands. The 1700€ Cabasse Abyss is an empty box using a tiny ICEpower module and some circuit boards for inputs and streaming. What a joke!
