YES! ... another convert ... i'm happy that you're happy.
just wait until you try the sunrise with some different tubes ... such as nos rca 12au7 cleartop, nos raytheon 5751 windmill getter, amperex 6dj8 (bugle boy) .... that's when the fun really starts & your wallet begins to cry .... but start with the rca 12au7 - you can get new/almost new 'organ pulls' at relatively low cost ...
try pink floyd in hi-res format.
i'll have some suggestions for you regarding dac, but not right now ... too tired. are you looking for pure usb dac or would you prefer one that can handle spdif coax/tos as well?
Quite a few things you mentioned that I can look forward to. I had already started shopping around for tubes and so your recommendations really help.
Where can I get Pink Floyd in hi-res? The Wall in high res format would be wonderful. Any of the others also, but I listen to The Wall about as much as all my other music combined.
For the DAC, at this point, I primarily need USB input to take the audio from my S3 and my PC.
In this regard, back in Colorado I have a very early Wadia DAC from back in the 80s. Do you know if these are any good at all compared to today's equipment?
