Class D amps seem poised to take over. Then what?


I am certainly biased by my lifetime final amp being a Class D. But I know that after 30+ years of development, Class D seems to be on a high plain. I know there are now many, many companies focusing on Class D and, maybe, a good handful already as good as it gets. My Class D amp is as smooth and beautifully musical as a great tube amp and as punchy and detailed as a great SS amp. I am satisfied and done with my search. A class D amp has effectively taken me off the amp merry-go-round. It’s about time after 50 years. And, for me, this Class D is a milestone. Will all other classes of amps fade away?

May just buy a Technics G-700 to hear how it sounds in my system


Go the far better integrated the SU-R1000, it’s said it also uses the far higher switching speed of 1.5mhz like the flagship SE-R1, which cuts down greatly the switching noise intruding down into the audio band. (class-D’s achillies heel)
And Technics is the only one I know of that has exploited this GaN technology feature so far.

I did audition a Rouge Pharaoh prior to the pandemic.
Opted for the 340ix with SF Olympicas.
Pharaoh was just not doing it for me.
@twoleftears could not get the page to load. Might be static or noise in the data link....
So back on topic.
As I said earlier I have bought a couple of Class D units by NAD and had kept one for out on the deck.

The M-10 I had firmware issues  and ran real hot.

Would like to try one of the Cantor tubed hybrid class D's though, on paper they look interesting.

Admin had a knee jerk reaction to the unfounded claims

All noise, when a subject is attacked for being snake oil, voodoo or whatever, that is fair game and keeps the shillers down.
But you then retaliate by attacking the poster or in the last case their dog personally. And that’s where the difference is, and why you get deleted more than anyone on Audiogon.🤦‍♂️
Is that you, skypunk, or is it earlflynn? Easy to get those two mixed up.
Good to see you dropped your selfie and have that aeroplane as your new avatar. Nothing like reinventing yourself, I’m told, but I’ve never had to do it.

As for my psyche, it’s never been better.
Your concern is so touching.
Are the meds working now?  😄

All the best,
Nonoise
@nonoise You are right I am a bully.
Hope you feel better, really I am concerned as this has effected your psyche.

Hope you are back soon.
Really all the best.
Pukeofearl. :)
@thecarpathian. Thank you spell check gets me all the time.
I will refrain.

Cheers.
Apologies to mglik,
but Earl, if you are going to continually use the word ’pious’, for Gods sake start spellIng it correctly!!!
I also find it odd that you continually say you are through, yet you keep coming back for more. It’s simple. See all those keys in front of you with letters on them? Stop pressing them.
I've read nothing but good things about the Rogue Audio Pharaoh.
I wonder if some of the complaints about the shortcomings off Class D are offset by the utilization of tubes...
I am very sorry to see that this tread has devolved into petty personal. Please bring it back to the subject.
Interesting that one of the last CL D threads included many good comments about the Legacy amp. Believe rh67 was going to Legacy to audition it. Any result?
And in this thread, the “amp de jour” is the Technics. If I am not mistaken, that integrated is a digital amp not CL D.
Anyone ever owned a Spectron Musician? I had one years ago and loved it. It was one of the first CL D but used a big analog power supply with a large toroidal tranny. Had a great grip on the bass and music and sounded very really good. CL D has certainly evolved since the Spectron. Bruno P. Seem to be one of the geniuses of CL D, Alberto G. Of AGD and Ralph K. of A-S coming out with a CL D amp after 3-4 years of development.

@nonoise  or actually All Noise.
All our post were deleted.
You should really stop with these attacks.

I am not hiding and I have been involved with CAP for 20 years and have helped save 31 lives. What have you done?

pukeofearl, all Admin has to do is put everything back up and it would show just how big a liar you are. Now you're hiding behind deletions and hoping those who've already read them won't speak up.

@tvad all I did was ask a question.
@fiesta75 I really do not need any friends like the Pius @nonoise. I live in the real world not some little pond.

Well time to go,  have to run another simulator.

Unstable?

all I did was ask a question and you keep coming at me.

You started name calling and digressed even further.

Only bully is you and your persistent attacks.

Big fish little pond and it appears to be getting smaller.

I will no longer play your hate game. Save your energy composting a retort as no one cares, least of all earlthepearl eating his goulash with a dingo.

Need to go do my CAP duty.

To wake up and see that Admin had a knee jerk reaction to the unfounded claims of racism from a pair of losers sickens me. And they still have georgie's post up in the matter. 

After losing so many arguments in the past on the simple matter of fuses only to see georgie jump in from left field on a discussion of Class D amps to join in with earlflynn, who's still pissed off from his lame attempts to protect MC when he went off the rails on another thread, shows more than a troubling trend.

Neither one had anything to add to the discussion and just dog piled on me for revenge's sake. Then to have Admin fall for the asinine, hail mary claim of racism against me speaks volumes for their ineptness. Their quotes of what I said had no racism whatsoever in them. If it was their intention to just clean things up, why leave georgie's slanderous comment up at the top of this page?

Both of these are unstable characters, yet Admin seems to want to play the hand of least, true moderation for the sake of, what? I certainly don't understand. When bullies are bested at their game with good doses of humor, it seems to enrage them, but hey, that's my style. I never opt to go as low as they do, which seems to make them only mad as hatters.
Having Admin mess things up even further puts a real sour note on the whole matter.

All the best,
Nonoise

No tubes needed to make my EVS 1200 sound better, just a change from optical to coax did the trick

Mrmeanor, by now, you should know better than to put all the products from individual classes (be the A, AB, SET, OTL) into one opinion, especially since you only included the Sudgen amp

I have owned quite a few class D amps over the last 2 decades. Assessing them in hindsight, my entire system has improved exponentially, rendering any of my negative opinions moot. The more current improvement was replacing the cable between my power supply moded Oppo 105 and Audio Alchemy DDP-1 + PS 5 dac/pre with a $59 Pangea Premier Coax cable. That said, it likely would not have made the improvement that it has in my systems of old.


My class D amp of nearly 2 years now is a EVS 1200 based on dual mono IcePower modules and a lot of Ric Schultz pixie dust. These are same modules in the later introduced PS Audio M1200s, but without Rics magic
I’ll just drop this stereophile.com review here. 

I wish I could show you a picture of the old Carr Street Sugden Factory in Cleckheaton, West Yorkshire, UK—or let you feel how warm the heatsinks were on the Sugden A21 SE pure class-A integrated amplifier ($3250) that powered the DeVore Fidelity Orangutan O/93 loudspeakers ($8400) in the room John DeVore shared with Sugden’s importer, Jonathan Halpern of Tone Imports. (The original A21 was the world's first production pure class-A transistor amplifier!) 

Trust me folks, class-D is like fake cocaine compared to the rolling, relaxed, shroom-like beauty of the Sugden A21 SE’s midrange. It was the end of the day: John and Jonathan knew I was revved up but that I’d relax when they played one of my all-time favorite songs, “Raining in My Heart,” by Slim Harpo. Slim’s harmonica was oozing Crayola colors while his words put darkness in my chest. I loved it—and I started to chill—but just a little. I needed more records and sweet sounds.


Hmm I have owned Class D, Class A, Class AB and there is zero chance I will ever use classe d in my main rig again. Class-D makes the music sound quantized with unnatural edges to the music.
Good video unrelated on how quantization has messed up music. https://youtu.be/AFaRIW-wZlw
The "R"word gets thrown around so much anymore it loses its weight. A cloudy day is a result of systemic racism for Pete’s sake.

Anyway, I LOVE my Wyred 750 LE. Yes, I even enjoy it more than my previous First Watt F7.
I know that’s not going to go over well with most but it is what it is.

I noticed my electric bill went significantly higher with the F7. A lot of times I leave the house two or three times in the day and I really don’t feel like shutting an amplifier off. If it’s class A, I certainly don’t feel like leaving it on for days. With my Wyred, I can.


Wow, not only an "fuser" but a racist as well, that explains all, and has something against our Aussie Dingo's too😵

Cheers George
Composing compost as that is what comes from your cesspool. 
You really should get a life.

Later All Noise and yes you are a racist.

@nonoise as a Black American I take offense in your racist remarks and will be taking this up with Agon.

Also I deleted those posts no one else. I was out of line and apologized. So now you have stepped off with racist comments and there is no coming back from that.
 You are a child.

f
or revenge at losing so many arguments. Keep your Dingos away from him when he's like this folks, or he'll be up on charges again.

As for earlthepearl, how can we forget the noble fight he put up in defense of the defenseless, which got all his posts deleted last time around. Seems that revenge is the rage with these losers.

Everybody's talkin' at D
I don't hear a word they're saying
Only the echoes of my eyes

Posters stopping, staring
I can't see their faces
Only the shadows of their I'ds....

(And apologies to Nilsson & Neil, F.)

Thanx to @mapman  for triggering this...whatever....*G*

Happy Sumday, the total what you make of it. ;)


@nonoise . No not at all only thing unraveling is you.

Such a child.

@nonoise you never answered the question.

You need to stop huffing your own fumes.

Later All noise Kamala, could use in in El Paso where there are no border issues.

I use a  ICEedge 1200AS2 based amp in my main system and a Purifi Audio 1ET400A amp in my bedroom system.  Both are tempered by tube preamps and I have absolutely no complaints. 

I live in the Caribbean so cool running and power economy (electricity is expensive here) were high on my shopping list. I can't really say that I find the class D amps sonically different from the class AB amps they replaced.  

I assume there are sonic differences, but my 55 year old ears are unable to discern them, so I couldn't care less.

Lets end this. I do not like you would rather play with rattle snakes than listen to you.

He's a strong avid fuser, and that about sums it up in one word

"FUSER"

Cheers George
Just as the OP i have the AGD Audion's and i find them to be fantastic one of the best amps i have heard regardless of class. Are they the best i have ever heard NO but i would have to spend 7-10 times their cost to better them. The best amps i have heard were also Class A so i would think it a shame to have these amps fade away. If i could justify the cost yes i would own one of the mega buck Class A amps but i can not so i own the next best thing the AGD amps.
@nonoise I am back and only a fool drinks and fly’s.
Multi Engine Commercial and it is only a hobby.

So Capisce you are a small fish in this pond son.

I am not being stupid unless you feel asking a question is stupid and yet you still have not answered it.
Please do not call me stupid a BSME and a MSCHEME and an MBA say otherwise.
Like I said big fish in a small pond and that this forum is your pond.
Thank you for being respectful of our son.
Lets end this. I do not like you would rather play with rattle snakes than listen to you.


I switched to Class D 13 years ago, had all sorts of amps and even had a Sonic Frontiers Power 2 SE, that was a amazing beautiful sounding beast, 125 lbs, 8 KT88's, and the size of a coffin and could heat a mid sized home.... Switched to Channel Islands Audio class D amps and never looked back, better tighter bass, all the air, weighs not much and barely runs warm... CI Audio is one of the best out there in the class D realm IMO
@earlflynn, are you under the mistaken belief that I and others just hang out on this forum with nothing better to do? None of this happens in "real" time. 

Sorry to hear about your son but you're sadly mistaken in thinking I hate cops. I have one uncle who was a captain and ran 44th St, Shootin' Newton, Rampart and other divisions. He was also in IA and sorted out the bad cops. He was also one of the lead investigators in the Charles Manson and Sirhan Sirhan cases. 

The other was an Asst. DA for over 30 years with a 98% conviction record, and while we're at it, another was a fire battalion chief. You know where you can stick it. Besides, it's not the side I support that stormed the capitol and beat and killed police. Were they people you supported?

Next, where did you get the idea that I'm a strong supporter of Class D? I'm just asking questions that you need not butt in on since you're all into tubes with your Hungarian Ghoulash amp, so remember, don't drink and fly when getting those tubes. We'd hate to lose you as you're such a distraction.

It seems comprehension is not your forte. Why would I ask about the Technics if I've already tried it in my system? Not ranting. Not raving. Just asking. There's no magic in words so saying something stupid doesn't make it so, no matter how many times you say something stupid. Capisce? . 

All the best,
Nonoise
what does it say about an amp that needs-
*tube front end
*justification with specs
*a front end " class A analog cell " 
?  

@nonoise You still have not answered the question.
As you are such a strong supporter of Class D Have you heard the Technics Integrated in your system?
Must have as you are raving about it.
Or are you going to keep bopping and weaving.

Think you need some Cl in your pond.
