This question still drives me crazy (and not because I don't like to see it posted either) as grounds and neutrals are all the same at the service entrance. I mean, in theory I understand why one would want a dedicated circuit and I actually have one for my gear only because nothing else is running on that particular circuit - just three wall outlets only used by my gear (technically I run digital and analog all on the same circuit). But still, as with mostly any residential wiring, the grounds and neutrals are all connected anyway. So what good does the dedicated circuit do besides giving your gear full service on the circuit without perhaps feeling the effect of a large central a/c unit kicking in and out, or the refrigeration compressors doing the same? Don't mean to sidetrack this post but I'll be anxious to read anyones thoughts here.
The above posts are right though, take it (the PC) out of the equation for awhile then see if you can really 'hear' a difference. If you can, leave well enough alone (assuming its a positive difference - not just 'different'). If you can't, maybe a lower cost unit would make sense if you could use the savings elsewhere.
I keep a low cost PC in my system more for the variety of outlets and trigger options then anything else. It sounds the same with or without. If my system actually needs something better, I've no clue. I'd rather just enjoy listening then worrying.
