Best preamp (used or new) under $350???


I'm thinking of upgrading my preamp but have a budget of about $350. I currently am running a Schiit SYS. I'm happy with it but it only has 2 inputs and I would also like a remote for volume. I'm considering the Schiit Saga but would like to inquire with the forum if there are others that I should consider?  I could buy new or used so please let me know your thoughts. 

The other pieces in my system are a Red Dragon S500 power amp, Sonos Connect, Onix XCD88 CD player. I'll also be connecting my tv via a SMSL Sanskrit DAC. Speakers are Kef ls50.

If you want a small footprint, the Parasound Zpre2?  It's currently on sale (brand new) at Audio Advisor for $277 (regular $399).
Hi, I retired a B and K reference 50 HT processor, all analog, about a year ago. I Have it going on 12 years or so.Great as a pre amp.  Going to set it up in a spare room. They are well made and received great reviews. I've seen them on Ebay/ Audiogon for as low as $250.  just thought I'd mention it. Enjoy your music!
