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’d save up more $$$ to get something that’ll provide a substantial improvement and just stick with your amp in the meantime.  I assume you’re also using the amp as a preamp?

It really depends on what improvements and sound characteristics you’re looking for from the new amp.  An older Class D amp shouldn’t be too hard to significantly improve upon. What’s your budget, and are you looking for new or used?
