Amp/Preamp Synergy for 6K Used

Rather than separates, consider going with the new BAT integrated. It has tubes, phono stage, remote and it fits within your budget (new w/ warranty). Assuming you like the BAT family sound, synergy clearly won't be a problem. It will also allow you to save on an interconnect.

$6K for an integrated? I've always heard of the compromises to expect with integrateds. How is this one different? I assume you refer to the VK-300x. Sounds good from the literature, but I am a bit skeptical about the modular desgin - adding super tubes, phono stage, remote, etc.

There's a front cover review in the latest TAS. I've never seen or heard the product and I'm only suggesting you consider it based upon BAT's overall reputation. It certainly does look good on paper. Obviously any integrated must represent some level of compromise when compared to separate components. However, if you're willing to accept less than an amplifier chain consisting of a separate phono stage w/ outboard PS to preamp w/ outboard PS to monoblock power amps, then at least in theory you're willing to accept the type of compromises inherent in an integrated amp. JRDG, Musical Fidelity, YBA and now BAT are redefining what is possible in a single chasis.
