Mikey you might kill me, but I strongly prefer the tube sound here. To me the class D had a slightly flat sound and it was as if there were a film of plastic around the music. The tubes evinced a feeling of realism from me. I felt like the singers were there with me.I could hear the harmonic glow, but it's a positive if anything. This was one of the starkest differences I have heard yet. Very different sound characteristic.

@@OCDHIFiGuy I see-so the tube-like design of this class D amp is for the look, not because of some technical or acoustic considerations

The class D amplifier sounds very clear and analytical. However, it doesn’t have any warmth or body or emotion to the sound. Harvey Rosenberg once said: “everybody out there is trying to find a Wolitzer jukebox sound.” Unfortunately, the class D sound is something I think most people will relish at first, but get tired of it in the long run. If you can’t have absolutely real sound, then we as humans want a more emotional sound. Think about it, when you hear an old wooden tube radio play, there’s just something that draws you into the sound that makes you want to listen. You can call it warmth , body, emotion, but there’s just something that attracts people to such sounds. Bob Carver try to make class D amplifier’s and failed miserably with it. Yes it may be the newest thing out there but if you look it up, you can buy amplifiers that use that GaN Fet technology for about $1700 bucks for a pair of mono blocks. And you’re selling a pair of them for over $7500.

When we get to mission critical equipment, (Like HiFi is for me) then I choose what's smart, not what makes me emotional. Strippers make me FAR more emotionally charged than my wife... same with Drugs and Alcohol... FAR more of an emotional guy.. a freaking emotional mess is most accurate. So these days I prefer balance and the smart choice that brings no anxiety with it. Tubes have far too many variables. They sound different all the time, depending on their temperature, age, country of origin, manufacture date, materials used, vacuum pressure, pin surface corrosion, vibration of the glass, etc. It's a big ball of anxiety for most of us if we actually get real with ourselves.. so the woody radio is cool simply for the fact that something that old is actually working. It's neato. I love it too. But we can't compare its function with what's better in every way. I suggest that the "emotion" you speak of is actually audio anxiety, brought on by distortion. I also suggest that it is similar to addiction in that it excites us but never completely satisfies. There is never an end to it. And Bob Carver crap is old and crappy. I agree...

The next A vs. B challenge in this setup must be the Rowland Model 125 Class D amp against AGD Audion Class D amp(s). To be fair, one might consider allowing 2 Model 125 amps configured as single channel, non-bridged mono-blocks for the comparison against the AGD Audion mono-blocks to offset the power supply differences between a stereo amp against two mono amps. Or alternatively, compare the Model 125 stereo amp against the AGD Tempo stereo amp. Let the struggle session begin for Mikey!! 🤡

Mr. Kutheis attended the seminar organized at CAF22 this last November, the seminar was specifically about GaN MOSFET in Class-D topologies. Michal Jurewicz and I proposed and coordinated the event in collaboration with the CAF22 organizers. A seminar that based on the collected feedback was extremely appreciated by all the attendees, maybe except for Mr. Kuthesis During my presentation, almost 50min long, Mr. Kutheis asked in different moments, various questions that were addressed and answered in full and in real time by me; his final question which by the way was not pertinent to the theme of the seminar, was what I thought about Mr. Putzsey and its Class-D products. I replied that as a rule, AGD does not comment on any competitors in the industry (for professional courtesy and for ethical standards we strive to honor), and as a personal discipline, a discipline I learnt in the hard way in a few years of life (62): I don’t comment on people or things I have no knowledge of. This was (and is) the case of Mr. Putzsey, which I never met in my life, and the case of the Purifi products, which I never had the opportunity to study or test. Mr. Kuthesis insisted to know more about why the technique to cope with the noise of the Purifi products (reading his comment I understand he was probably looking to a reassurance about the choice he made in acquiring those products). Again, I tried to address that question by describing the many components of the noise in an audio circuit, and how in general designers may use different techniques to cope with it, among them filters and high negative feedback loops, which sometime I remember I said, can have a detrimental effect on the quality of the sound produced. Again that explanation was apparently not satisfactory for Mr. Kuthesis, he insisted on the subject and at that moment Michael intervened by providing an answer that although very generic, produced the successful outcome to make Mr. Kuthesis silent, so we could continue and finally conclude the seminar. So if Mr. Kuthesis thinks that I have a short fuse, he is certainly entitled to his opinion, and he can post his opinion anywhere he likes, as he did already on another video about the review on another AGD product. What is however weird to me is why he is so pedant in recounting something so peculiar and yet by omitting key facts. I believe I was very professional and accomodating Mr. Kuthesis, but clearly he likes to smear our brand using the excuse of an alleged short fuse...may be he should lear to listen more, and not just the music.

For sure, Chris. What we have here is a disruptive technology. It smashes the traditional belief system, and people don't like the idea that what they've believed to be true may no longer be true. It does not mean people still can't enjoy tubes, but the proof is in the pudding. One has less distortion and sounds just as natural. ;-)

You’re the ONE that has to LIVE with it !!!???

Try a high end class AB amplifier including a vintage one. The sound is a hybrid between GaN and tubes.

Not all 300B sets or sets in general sound has those syrupy sounds. Listen to Kondo amps to hear what a good SET can do. SETs are simple devices and are very response to tube rolling changes. If you use syrupy tubes or have mushy sounding caps, you will have a mushy sound.

@OCDHIFiGuy

Mushy sounding Caps ? Very responsive to different tubes ? Thats the LAST thing I want in my audio system. Something with sound that is always changing or can be changed easily. I've got 5 pair of tube monos including $30K monos. 4 stereo tube amps, 3 rube preamps, a tube crossover and a tube EQ. One Day it all gets old when you realize a tube rig = change of sonic performance anxiety.

Thank you Mikey for a wonderful comparison, the sound demo was rewarding in many ways....! My opinion is relative to what you want to hear : Both amplifiers sound great, the 300 B sounds warmer, sweet, easy to listen too for a longer period of listening time, reproduces the even harmonics slightly better than the D Amplifier. The D Ampifier using Gallium Nitrate Technolgy sounds great, however it has a Digital Haze what i mean is that whe i listen to the sound it seems a little on the edgy side maybe slightly grainy ( Granular ) The antithesis is the following Gallium Nitrate is an intersting upcoming technology but still reuires refinement; if anyone sitts down for a longer period of time listening to music the 300 B will be more plesant to the ear and the individual will tend to listen longer to the content. In summary and this is my opinion only; in todays market one cannot justify the high cost of a Gallium Nitrate Amplifier over a 300 B. I personally own high end SET amplifiers and transistor amplifiers. Is one better than the other i always come back to the Vacuum Tube Amplifier ....! Why because i have no listening Fatigue when i listen to source music on this type of technology.

Жыл бұрын

In Room, the tubes were midrange forward and aggravating. We had to search for songs that we could play. Not so with GaN. The GaN sounded better in the room. It was easy to hear. Perhaps Canary Audio is shit. Even with top level tubes. I'll retry this with some $30K Tube monos to see...

I like the tube.

Mikey discusses soul in music, connection to music, i.e. through the correct rig setup. Completely agree with that and was never one for over detailed or forward sounding rigs, perfering to listen into music instead of being forcefed it. I've listened to many class D amps and have owned several and for a short while, been impressed, but eventually find them a facsimile, lacking soul and presence when compared to class A/B, even when those A amps are less cost than D. So I'm very surprised to hear Mikey advocate any class D. OCD plays it straight, and has music reproduction taste similar to mine, so I have to assume he just has found some class D amps that don't sound like an over hyped AV receiver, but actually sound smooth and linear through full band width. If this is the case, then the case for A/B and tubes is fading except for nostalgic purposes. As of now, I'm sticking with A/B until I get a chance to listen to one of these recommend D's for a couple of weeks and not for a couple of minutes.

@OCDHIFiGuy

Жыл бұрын

That's what the common repeated thought may be, but clear detail does not mean fatigue, in every situation. The best systems have clear, well defined leading edge, fast transient response and ZERO fatigue. Making this happen is harder than it sounds however. In my experience it's the job of the DAC. In this listening session, contrary to my expectation, the tube was more fatiguing due to a midrange push and what I suppose is distortion. Distortion/ noise is what fatigues us. So the GaN tube with the Playback Designs MPD-8 DAC was the most balanced sounding and least fatiguing. It totally took me by surprise. I did not expect this.

yo mikey i promised no more tube talk but since you are still on the matter...i specialize in guitar amps and owners of home tube gear are not that different from guitar players, they are not orientated about swapping tubes, like i was before i was enlightened to be a local guitar amp tube guru. i didn't want to fuck with it or tube roll i wanted to play guitar, till i had to swap tubes and the new ones were horrible so i sold the amp...years later working as a backliner on gigs with guitar amps that sounded bad i went into the vintage tube rabbit hole with a digital tube tester, a guide-the tube king and my ears and guess what? even the most professional guitar players have no clue about vintage tubes ,the best parts ever made for the gear they use, most people with tube gear home and guitar amps, will never hear it properly, the full potential. i used to tube roll now ,after ten years and dozens of retubed amps i don't have to tube roll anymore and i don't get people into that idea ,i just pick the best part ,nos for every position in the amp and jaws are dropping since i replace modern junk with holy grails and it's easy to get great results. most of the magic to my opinion is in the preamp so comparing power amps will show the tubes weakness less grip on the bass usually less power, you should compare no preamp to a good tube preamp(your pick) thanks for a great video i'm still biased about tubes...(got that? biased...)

And thats why you should never judge the sound of an audio system based on the KZread - they both sound terrible, but in the different way - both very tuby, muffled, muddy, not realistic, lika a speaker wrapped in the feather quilt.
