Time to buy a class D amp?



Will some new class D amplifiers outperforming the current ones appear soon

(the newest ones i know were released a  few years ago)?

Class D amps attract me as I consider them the most ecological ones with obvious non-auditionable benefits.

I have no doubts that they posses the maximum ratio performance/sound quality among the amplifiers of all classes.

At the same time, the sound quality the class D amplifiers that I have auditioned produce, although is quite good,

but not yet ideal (for my taste).


I use PS Audio Stellar S300 amp with PS audio Gain Cell pre/DAC with Thiel CS 3.6 speakers in one of my systems.

The sound is ok (deep bass, clear soundstage) but not perfect (a bit bright and somehow dry, lacking warmness which might be more or less ok for rock but not for jazz music).

I wonder if there are softer sounding class D amps with the same or better details and resolution. Considering two reasonable (as to the budget) choices for test, Red Dragon S500 and Digital Audio Company's

Cherry  2 (or Maraschino monoblocks), did anybody compare these two?

I've owned 3 class d amps over the past five years.  The Crown XLS 2000 at $500 did some things right and some things wrong: good low end, ok midrange, bright top end, huge soundstage but two dimensional, and somewhat blurred detail...but for $500....kept this amp for several years.


I also owned a Nuprime STA-9...their class a/class d hybrid said to emulate the tube sound; $700, better low end...better detail...slightly more three dimensional but somewhat bright (in my system at least) in the upper midrange and top end....kept this amp for a couple months.

Now I own the Digital Amplifier Company 2Cherry...$2400 (for the past 6 months)...and for that increase in price, you would hope/expect that things would be a lot better...and they are, the best amp (including tube amps and class a/ab amps) that I have ever owned (so far?).  Great detail, great clarity, great soundstage, life like realism (in my system with Salk loudspeakers with RAAL tweeters).  No weaknesses...not a hint of brightness.

My advice...since amps DO sound different....and since class d amps are generally lighter in weight and less expensive to return....try 2 or 3 of them at the same time and send those back that don't give you the sound you are looking for....$50+- if return freight is nothing compared to getting to hear them in your home, on your system with your music.

     I think this is a good idea once you narrow your list down to amps you'd like to audition.  Most class D amps are sold internet direct and offer free in-home trial periods for a certain number of weeks stipulating you can return it for a full refund with no questions asked, and sometimes with free return shipping.  But I agree with snapsc that even paying a reasonable charge is worth it to hear it in your system and room.
     You could even add a column for "Trial Period" that lists the offered in-home trial period in days or weeks.  The only downside is that, in my experience, class D amps take a while to properly 'break-in' and perform optimally which could be longer than the trial period.  However, the three class D amps I own sounded very good right out of the box but still kept improving in sound quality over a number of weeks after until the sound quality stabilized at each amp's optimum quality level.  The danger being that the ultimately best sounding amp just happens to have the longest 'break-in' time and the in-home trial period was too short for you to discover this.
    All of my class D amps have been on 24/7 for over 5 years now and are still operating flawlessly (knock on my head).  I suspect their low internal operating temps likely only increases their lifespans but this currently lacks scientific, objective and independent validation.  If longevity concerns you, you could also add a column on your list for warranty length and terms.

Good luck,

Thanks indeed, Tim and @snapsc for your comments! 

I did not know, Tim, that all these brands produce Class D amps.
It would be virtually impossible to verify all of them (but will make a search for some of them) and given that i live in Mexico, buying and returning would not be really feasible. 

Although I am not yet completely convinced that it is already time to buy (another)  class D amp, i am still desperate to try one more because i like class D concept. I listen to 2-channel systems (no home theater!)  and could take an option of a stereo amp or monoblocks. Naturally, i would only consider a candidate with a high coefficient *performance/price* according to my vision of class D concept. 

@snapsc, your impressions on 2-Cherry after trying two other (known for me) class D amps are important for me. I was also inclined to a Cherry amp. The biggest and supposedly best one is Megaschino  (should be very good at $6900 in class D), then comes Gold Cherry with the same price i think and Cherry 2 with a much more accessible price. My question is, which of these three models maximize ratio  *performance/price* ?
Did someone compare these three? 


Hey niodari,

     If you're looking for the highest performance/price class D amp and don'[t mind buying used, I think the Merrill Audio Veritas monoblocks are a great option to consider.  Reviews on these amps claim they're among the best performing amps available regardless of amp type or price. They sold new a few years ago for $12,000/pair but I've recently seen numerous ads from owners with an average asking price of about $5,000/pair.
     Merrill audio recently came out with a new lineup of Element amps utilizing extremely fast switching GaN transistors that virtually eliminate 'dead-time' which significantly reduces distortion and improves sound quality. These include the Element 114 which is a stereo amp priced at $15,000 and 2 monoblocks,  the Element 116 and Element 118 priced at $23,000 and $36,000/pair respectively. 
      I'm thinking  the reason numerous ads are appearing for used pairs of Veritas amps is due to current owners of Veritas monoblocks planning on buying one of the Element amps and are selling their Veritas monoblocks in preparation. I strongly believe you'll prefer the sound quality performance of the Veritas amps over the Cherry amps but I can't know this with certainty.  Here's one of many good reviews on th Veritas:

Hey Tim. An important attractive side of class D amps is their low price 
and high ratio performance/price. I am not sure if for Merrill class D amps this is also true. Neither you nor me have auditioned it, given their price, they should sound almost magical to have a high ratio. Buying   Merrill amp would be similar to buying a very expensive electric car. I have a hybrid one which did not cost much more than similar non-hybrid onces, this made a sense. Demo Cherry amplifiers are on sale, some of them cost nearly the half of their normal price. If their sound quality is somewhat close to  Merrill class D amps (at least, not too far), ratio performance(Cherry)/price(Cherry) >> performance( Merrill)/price( Merrill)
even considering used price. And, perhaps,  older Veritas series amps are not magic sounding (if not, why they have changed the profile of their class D amps?). I am curious to compare SQ of Cherry,  ATI, Veritas and Element amps
