Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other???

Hi,

We are still doing our direct A/B testing with several different Class D amplifier brands that use different technology and I am certainly not a tech but the differences in sound between the different technologies is very audible. There are 4 amplifier manufactures that we have A/B that sound much better than other Class D manufactures we have tested. We are still testing and we still have a few more amplifiers to test but one thing for sure, Class D amplification comes in many different levels and the top level is very special. The problem might be, if you have not heard the very best of Class D, than the not so good Class D is not very good at all and this might turn you right off Class D.

Yes I have 3 Class D amps ranging in original retail price from $100 to $6000 and I can say with certainty each sounds good but different.

I’d specifically be wondering are you testing any Class D amps with the GaN technology? If so how does that compare to the others? Also the cost of each.


Thanks.

Noble100, both GaN Systems and EPC hold patents on the GaN transistor tech. 

I fell in love with class d when I bought (go easy on me) the Pioneer elite
sc-09tx uber-receiver, some years ago. The bass and mids were absolutely intoxicating and to die for, while the highs were grating and painful. All coming from a pitch black background, no noise. It was definitely a good news, bad news sort of thing, but when it was good, it was REALLY good.

It became like a drug addiction, I desperately searched for something that reproduced that fantastic mid range and powerful bass and that dead silence, without the harsh treble it was known for.

I’m now using wyred 4 sound mono blocks, and they’re just okay. They don’t add anything untoward, but don’t have much in the way of punch or bass kick I like to hear. They're just not exciting, like the Pioneer.
I’m now looking for a replacement for my amps....much like the OP.

These are Ice powered Class-D’s also, you stated below they were bright also, what speakers do you own, maybe that new GaN Technics SU-G30 could be good with them?

Anyone with opinions on Wyred4sound’s monoblocks? I recently bought three, and they sound bright without much bass. Anyone?

Here is the Technics SU-G30 review.

The musical reproduction offered by the Technics SU-G30 was among the best sound of any amplifier I have ever reviewed. Technics has a short preamble in the manual that hypes the great sound of this amplifier and I agree with their marketing-driven assessment. It is ironic that the better digital gets, the closer it sounds to analog. Tubelike even. And at some point, digital can have the best qualities of digital and analog at the same time. This is how I view the audio prowess of the Technics SU-G30 – it is like analog, super clean analog at that.

My generalized listening impressions involved excellent purity of tone, a huge soundstage, amazing detail retrieval along with surprising excellence on streaming services.
