Preamps for $300 to match with B&K st-140?

Im trying to get a little more warmth and power to my JM Labs Chorus 706's so I picked up a B&K st 140 amp. Now I need a pre to go with it. I want something under $300 that has a tone bypass, and maybe a phono input. Im going used so vintage is ok. Tubes are good too. Thanks for the help!

I'll put in a vote for the B&K Pro 10MC preamp. Stereophile Class C in it's day. Nice phono stage, external power supply, balanced output, can be used as a passive preamp. I used one for several years and thought it was a pretty impeccable for it's $850 list price.

You should be able to pick up an older conrad johnson tube pre (like a pv 1 or 2) or in ss, a mccormack micro line drive.

Sorry, I have to disagree with the passive and AI recommendations. The B&K ST140's rather low input impedance does not make it an ideal candidate for passive or high impedance out-put preamps. I tried a couple of passives with the B&K and didn't care for the combination. The B&K Pro 10 could be the ticket. The B&K ST amps can be a bit mushy in the bass, becarefull not to overdo it with preceeding "warmth".
