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 would not so much concentrate on the technology used, but the sound of the components. 

I’m not sure you would not be better off keeping the PS Audio preamp. I have not heard it, but it was higher level preamp when made. It seems your Denfrips is much higher end than is your preamp or amps. I would look for used higher end equipment. 

The Gato dia 400s number one class D. I have in the past cello,conrad,krell but the gato is one of the best. And for his price.

I have bought 6 items from Schiit and never had an issue with any of the products.

They were very responsive when I needed advice once.

Recommend them highly. Just felt I had to add something here.

My remote died over a year ago. Good News; the new PS Audio remote is available. Just call them

As to the mods I had mine done as new. There are likely newer upgrades. Just call Parts Connection

45 days ago I ordered the Kara on line.  Arrived 10 days later…packing was not fancy but it was well protected. Worked perfectly right out of the box. Dead silent black background… big soundstage, no clicks or pops when switching… all in all, very satisfied.

Also, their AI for answering questions is quite good…. so I can’t comment on their service. Although their return policy isn’t great, it is probably worth considering.
