Class D is just Dandy!

I thought it was time we had a pro- Class D thread. There's plenty of threads about comparisons, or detractors of Class D.

That's fine, you don't have to like Class D amps, and if you don't please go participate on one of those threads.

For those of us who are very happy and excited about having musical, capable amps that we can afford to keep on 24/7 and don't require large spaces to put them in, this thread is for you.

Please share your experiences with class D amps!

Not sure about how sighted tests of power cables would even work.... May be some rare sighted people are able to hear through their eyes instead of their ears?!


Oddly enough, I experience no difficulty discerning differences amongst power cords, exotics and inexpensive ones alike. On the other hand, what would I know.... I have been as blind as a bat in a sealed barrell of tar for the last 33 years. All my audio tests have been totally blind ones since 1984.


I must be really unfortunate, being bount to  listen to music only through my ears *Grins!*

Like I said once before, to the ones that have blinkers on, they will be the first to change to the higher switching frequencies when they become available, that's almost a given. 
As for now maybe just trying to protect their investments, with ignoring that the higher switching frequencies will give them what many hear is a problem with Class-D, which effects the upper mid/highs.

Hi George, it is quite possible that an increase of switching frequencies by by a factor of 2, 5 or possibly 10 might very well enhance the sound of well designed class D amps.... Or at least, such higher frequencies might be a contributing factor.


I have not heard the new Panasonic that use these new transistors, so I do not know how they would compare to the current crop of the better class D amps.... But sure am curious.


And when reproduced music becomes even more enchanting than what I experience now from my Rowland M925 monos, I'll be the first one to celebrate the event.


Have you heard these new Panasonic amps yet? If you have, please let us know your first hand impressions.

Have you heard these new Technics SE-R1 amps yet? If you have, please let us know your first hand impressions.

Saluti, G.

No I haven’t yet as the Technics SE-R1 is unobtainium here in Australia, and you need to order them and have deep pockets in counties that do retail them.

But from the number of Class-D’s I had here listened to and measured, they (Technics) seem to address to a certain extent the problems that they all have still, which is the filtering that has to get of the switching frequency noise, without it effecting the audio band in any way, and the only way to do this is to raise the switching frequency by at least triple, Technics have done double with the SE-R1 so were on the way.

But these are typical of reviews (below) of the sound they give out from those that have heard it, and there are more from others on the web.

" Listening to tracks that we’ve heard 100s of times — and on excellent systems at that — is now a revelation of once hidden nuance and detail. Not only are we hearing things we’d never heard before, we’re hearing it in a way we’ve never heard it before. A music system that sounds like a live performance is a tough goal to attain, but Technics’ flagship nails it."
