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.

Al, I couldn't have said it better.  I have owned some HUGE clubs and have cooked more than one piece.  The worst casualty was melting some Niles gear after running too much wattage for too long of a time.  Our original QSC amps never failed us in 10+ years. But, when used at home, they sounded awful when compared to many home audio amps.

The L150 is fairly efficient and doesn't need a lot of power.  Because you need to run 2 pairs of speakers, some of the vintage receivers from Marantz, Nakamichi and others may make sense.  They have great built in tuners as well.
Schubert, I'm still running the stock tubes, and I haven't done any rolling as of yet. The sound is sublime as is. But from the research I've done, it seems that the stock output tubes are well liked and difficult to surpass. However, the input tube can be configured to your personal taste. I'm going to try one of these in the platinum grade cryo treated flavour. http://www.upscaleaudio.com/telefunken-e88cc-6922/
