Need Advice on a Tube PreAmp & DAC on a Frugal Budget

My Frugal budget is $1,500ish give or take $500 :).

I’m not a high end audiophile by any means and don’t think I would ever be, but…. I’d like to have acceptable sound to my neophyte ears. I basically listen to Classical/Jazz but also rock once in a while.

I’ve been buying a different piece every year for the past 4 years and tried to incorporate everything into an all in one Home Theatre.

What I currently have:

Polk LsiM703’s
MIT AVt3 speaker cables
SB SV-2000
Parasound HCA 1500A
AVR Pioneer VSX-01TXH receiver

I rarely watch TV or movies anymore, so I’m looking to get an acceptable Hi-Fi system. Currently I go from PC to Receiver (HDMI) when playing my digital rips and I have some HDTracks High Res.

So...I’d like to get a separate Preamp and DAC to stream HD music and play my digital tracks. I don’t own a good CD player (transport?) or turntable. But I may get a CD player at some point, not sure on turntable.

I would buy used if from a reputable seller and I’m not against building kits if they come with good instructions.

Hopefully you folks with more knowledge can give me some items to research.

Thanks for your suggestions!
