very Awsome indeed Misternice, I believe, on the most part, The Rhodium GTX-D on tube digital is It from your very useful feed back, I already have the best speed and slam I have had on any system that I have ever owned, so to keep that, and not to add a sound that will change my sound, The Rhodium would be good for that position, what was your impressions on the solid state amp between the Gold and Rhodium?, Bob, whatever is your best sounding, biggest gauge for conductors power cable should go on the wall to power distributor, a power cord in this position carries the biggest burden of most componets, so if the Harmonix xdc2 fits that description, then you have what you need there, look forward to more, you are doing a fine job!, Happy Listening.
