Congrats on the 50! I think it's a great amp.
Spectral Pre's are nice. I've heard good things about the mccormack tlc 1 or microline drive with spectral f you're on more of a budget. What speakers do you have? I use the 50 with thiel 1.6, think they're fairly efficient, no problem.
My thought here is that if you use revealing speakers, the amp will pass everything through them, so you need a decent upstreatm (cd and pre)
