I am an owner of AYON CD-5 (bought used, but prob had very little hours on it, looked brand new), and it is really an amazing player (or DAC, as it used 80% of the time). I had the same question, and found on AYON S-3 manual on page 40 instruction on opening the unit, which has the same case as CD-5. But video indeed will be better.
Now I am thinking what tubes I should (and should I) replace. What tubes are actually inside - is it known?
