Please recommend preamp

I'm new at this but am trying to put together a nice system primarily for a large vinyl collection that can also play CDs and probably either a tuner or cassette player. I will have speakers in two rooms, neither very large. I started with the JBL 4312 speakers from my youth for the bedroom and then bought JBL L150As for the living room for $950.  I just got a QSC RMX2450 amp in excellent condition for $300. I think my next step is a pre-amp. What would be a good bet for around $1000?  I'm hoping to get it right the first time rather than test-drive and buy and sell; really, I just want to listen to my records.
