Recommended Pre-Amps under 1k?

Here ya go!!

Find a used Classe' Sigma SSP, and use it as a 2 channel line stage. Read up on it, it was built for 2 channel. Truly balanced. PM me I have one in the box collecting dust.

I just wanted to report back guys, the audiolab 6000A Play is being used as my pre-amp/dac/streamer and WOW just so impressed with the improvement. This will take me well down the road. The 6000cdt pairs well and sounds incredible. The two PA3’s used as baby mono blocks sound like they took a tier upscale. 
 

Sounds Amazing, so happy!

I picked up a Sonic Frontiers SFL -1 for $500 six months ago.   Great sounding preamp , Parts Connexion still services and upgrades them.   I have it in my system right now, my main preamp is being serviced ... it is one of the best values in used preamps out there, even though its older its built like a tank and I think I actually like it better than my cj Classic .   I have to decide which spare pre I'm going to keep ,  pretty sure I'm selling the cj and keeping the SFL....

Absolutely no affiliation.  This is a fantastic preamp for well under your budget.
