I'm really liking the audio alchemy dac/preamp unit. With the optional power supply it is exceptional and well within your price range. It was also highly recommended in an absolute sound review.
Pre amp with Dac
Is there a Pre with a dac included out there in the $2500 used that does a good job. I stream Tidal from my computer; no phono needed. I use Bel Canto 600ref mono's for amps. Thanks Gary
