Class D, "Control (Variable Gain)," Amplifier versus Class A/B Separates?


Hello, all!

I am currently running a quite old PS Audio GCC-100 in my chain. It is a variable gain, class-D solid state power amplifier with balanced stereo inputs (functionally a balanced integrated amplifier). I recently purchased and am quite enjoying a pair of KEF LS50 Meta loudspeakers, but have been hearing from numerous people that they may sound even better with Class-A or Class-A/B amplification. I am curious what benefits, if any, I might get from making a switch. I am currently considering selling the GCC-100 and replacing it with a Schiit Kara preamplifier combined with a pair of Outlaw 2220 monoblocks. Any and all advice about what I might expect from such a swap would be greatly appreciated! And in case it matters, source is a Denafrips Ares II R-2R DAC playing lossless Apple Music.

I was really turned off by Schiits demeanor but I held my nose and purchased anyway. I care about getting what I want. I don’t need to be stroked. But I do appreciate good CS and it does influence my buying decisions. 

decooney: Unless a company is the only "game in town" I will not buy from them.  anyone worthy of my business absolutely must at a "minimum" meet the key elements that you mentioned and then some.

There are way too many options out there to compromise on "anything" in life.

I give people the benefit of the doubt but once a company screws me, they do not get a second chance from me.  As far as audio equipment is concerned, Schitt and TEAC are two of those.

Maybe one day some of those companies will stop being so greedy and realize that there are those out there, including myself, that are more than willing to pay a premium to get good service, as opposed to trying to save a few bucks. You can't put a price tag on time wasted. Time can't be replaced! 

@eddnog There are class D amps now that don't take a back seat to class A or AB amps; very different from just a few years ago.

That's correct and Ralph makes some of them..Gato is good...Aavik is best but expensive.
