Hi Lou
I'm in same boat. Thinking about it hard!
If you're not already using networked music player, it is something to consider. They are pretty handy. Squeezebox, Sonos, Rocku, Dlink, Olive, there are a lot of them now, each with + and -.
Basically anything can be used as transport into the Altmann if you get the JISCO option which "filters out" the jitter from any transport/cable scenario, even cheap consumer grade stuff, although that may not last very long. With a true high end transport like Oracle CD1000 we did not hear any difference switching JISCO on and off. Some people have reported improvement when using JISCO with transports of lesser pedigree. I didn't here much change with JISCO engaged while using SB as transport either, but it has relatively low jitter anyway.
