I'm done as one can be. I'm to the point where I don't think I can make any significant improvements short of adding on to my house and building a larger room. I still play around with stuff that makes minor improvements but I feel like I'm running up against the limitations of the recordings more than the limitations of my system; and that is a good place to be.
BTW my previous CDP was the CDX2 that I was running off of batteries, which to my ear was much better than the internal supplies. I never tried it with the XPS2 but I had it for a few years and it was the best of many that I tried. The Altmann I have now is to my ear a much more musical device. The Naim is very good, and perhaps bests the Altmann in retrieving that last little bit off the disc, but the Altmann gives up very little in that area. The Altmann is big and dynamic and the Naim polite and restrained. Probably at this level a matter of taste and the type of music you prefer but in my system and with the recordings I prefer the Altmann is so much more musical I could not go back. It also costs less than 1/5 of your Naim but you will need to add either a transport or go to a computer based system. Just when you thought you were done ...............
