A Newcomer to Digital Looking to Upgrade My Dac, Tubes? Ideas?


Being a relative newcomer to digital downloads and playback, I love the convenience when I am looking for a short music session and don't feel like going through my vinyl. I find the digital quality pretty good, but looking to upgrade my dac to get some additional warmth into my playback, I'm thinking maybe a tube dac, not sure what I should spend but cost wise was thinking of $ 2,000.00 as a budget. Not sure if such a dac exists, or if you have suggestions. I have built up a pretty good collection of both PCM and DSD HD music, mostly copies of what I have on vinyl but the vinyl has seen better days. Currently I am using a TEAC UD-501, tube preamp- (Schiit Mjolnir 2), Amp.- (Adcom 555se), Balanced throughout usually through my PC but I also use my portable through the coax to the dac. Speakers are Wilson Benesch Square 2. Unfortunately I have an L shaped listening room, which seconds as our living room, typical of what you find in a condo, volume levels are generally low to medium, to spare the neighbours, and I split my time between the speakers and headphones.

If you are a music lover a $2k DAC will not give you the sound quality you are used to with Vinyl.  Now if you just want music in the background then any inexpensive DAC will work.  I have had 4 Lumin DAC's ...U-1 mini, D-2, A-1 and X-1.  Each one was a step above and the sound level improved in each stage.  I now have a Lampi Pacific, which now exceeds the X-1.  Check out the Lumin Line for SS and there are some Lower end Lampizators that would shine.
Upgrade DAC?  Tubes?  Ideas?  

Upgrade the acoustics in your room.  It's a lot cheaper than electronics and more aesthetically pleasing.  Use a dozen or more artificial Ficus trees scattered around the room to be used as sound diffusers and absorbers.    
Don’t take any advice from jasonbourne52, he thinks everything cheap is better than anything you have to spend more than a couple hundred dollars for.  You could easily find a Audio Note Dac with R2R Dac, tube output and tube regulated power supply.
Good Luck with your search!
I tried a few Dacs and after being tempted by and MHDT DAC for months and researching way too much, I got an Orchid. It’s great. Adds some tube flavor to digital that just sounds right. Still very clear and with great dynamics and tube rolling helps to dial in the flavor. Highly recommended
