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.

Regarding the NAD C-375BEE, if you haven’t already seen it you’ll want to read this review, which glowingly praises its sonics aside from those of the optional phono stage and the built-in headphone amp. Which of course, given that reviews should not be taken as gospel, is not to say that you or others wouldn’t be pleased with the phono stage. But you might want to consider the other 375BEE that is presently listed at Audiogon, apparently without a phono stage but with a manufacturer’s warranty. It could of course be used with a separately purchased standalone phono stage.

Regarding the HK units, as I said in connection with the Nakamichi preamp you mentioned earlier I personally would be hesitant to go with a 1980’s product, as I would expect that eventually if not sooner capacitors would need replacement, and there would be significant risk of other condition-related issues. Especially in the case of a solid state product, for which both the availability of replacement parts and the difficulty of their installation often tend to be more problematical than in the case of tube-based products.
I had looked at the NAD C165BEE on this site...my QSC amp would "melt" it?
Since Elevick has not yet responded, I’ll take the liberty of clarifying his comments. The QSC amp would not have any adverse effects on the C165BEE or any other preamp. He was referring to NAD and other home-oriented power amplifiers, which he had found could not stand up to the rigors of commercial use. And he was implying that in contrast QSC amps were designed with ruggedness rather than sonics as the main priority. And that you may therefore do better in terms of sonics with an amp designed for use in the home.

I have no experience with QSC or other such products, so while that strikes me as certainly being a legitimate concern I can’t comment specifically. I’m just offering an interpretation of his comments.

I am with Al regarding the purchase of the older equipment. I do like to buy used, however not vintage (with rare exceptions).  I have a NAD 526BEE and think it a great integrated for the price. It lacks a phono stage. I have not viewed the add for the  375BEE so don’t know asking price. Do know that it is just one series earlier than the 5x6 series so is not that old and has more power so can drive a wider range of speakers. 
It seems that should you sell the QSC and had a budget for a pre of $1000 you have a budget of ~$1200 for a integrated and phonostage. Is this your thinking?  

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.
