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.

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

I bought the GCC 250 when it first came on the market. Still humming along. The GCC 100 garnered many excellent reviews and can be upgraded, as I did mine

I think it was Chris from Parts Connection

Also upgrading power cord, interconnects, and vibration devices are all positive

Good for you. The GCC is still hard to beat. FYI it does respond to better power cords and iso devices
