PS Audio DirectStream DAC driving VAC Amps


Anyone driving a VAC amp with a PS Audio Directstream DAC? If so, are you pleased with the combination? Did you find the VAC's hi-gain / input impedance to be a big improvement over your previous amp?

I started this threaded because I was considering a used Phi 200. Well I purchased said amp and had my first listen last night. I am very happy with purchase. My system has never sounded so spacious; the sound and soundstaging is fantastic. It's amazing what a great amplifier brings to the equation. And it shows what great upstream equipment PS Audio's DS Memory Player and DAC are.
Cannot speak to that combo, but the DS deives my Pass  xa30.8 very well.
