Hey there @terrapin77. Am very curious about your thoughts on your new DAC and how much difference the big step up makes. I'm a fellow SMSL user, though a little beat down the line at the Sanskrit 10th mkII. It's cheap but it's great, does DSD very well which you should look into for classic rock and jazz, plenty available. Well, the Tubadour III SE does DSD to PCM conversion "on the fly", so I guess not native. But your SMSL does! IMO it spanks PCM up and down the street.
FYI there's only 4 Dead albums on SACD, done by MFSL: Workingman's Dead, American Beauty, Blues For Allah, and From the Mars Hotel. The first 2 sound incredible like they do in any format. The last 2 not so much, and I much prefer live versions of those songs anyways. I have the 24-192 versions of some '77-78 Betty Board stuff, love the Get Shown the Light box, but the hi-res is barely distinguishable from redbook. Maybe I need a better DAC. This is a great thread, I have my eye on the Denafrips Pontus II for a (far in the) future purchase.
