best pre-amp new or used for under $500?


Hello there, just bought a 2-channel power amp and need pre-amp advice. My budget is low, as the title above states, and the power amp is a Rotel RB-1080. Speakers will be either Ascend Acoustics Sierra 1, Dynaudio Excite X16 or Totem Rainmakers. I have not auditioned these speakers yet, they are on my list because of reputation, look and price. Source is a Yamaha CD changer, will upgrade that after the speakers arrive. Room will be small, 12x12x8. Would prefer to have a couple sets of pre-outs so I can hook up a sub if necessary. A remote is an absolute must, my listening sessions are 90-120 minutes long. Thanks in advance and happy listening.

IRD purist, I have owned one twice because i regretted selling it, there was one here for under $400 STEAL. I now have musical fidelity a3cr which is GREAT for around $600-700

oh sorry no remote, look for a musical fidelty
NAD 118 Digital Pre. Great tone controls.Onboard Dac-sound adj.`s in digital domain.Overall sound competes well against higher end pre`s.No Pre-outs. You could hook-up your Sub@speaker level.
AS a matter of fact, I do own this unit, along with the ERC1 cd player. with their generous return policy you cant go wrong. give it a try
yes, I run a Velodyne fsp18, which I recently aquired. I run my Apogees full range, using the crossover of the sub instead of the usp1 crossover, If I was the run my Apogees using the high pass/low pass filters, I would use the crossover from the usp1
