I've been on this journey for a couple of years. It has taken me many places where I initially started with Swiss gear (Goldmund / Orpheus Lab) and then got enchanted with Tubes (Hence the original name for my virtual system - Move to Tubes). I was heavily into Zanden and Wavac for some years until I found Tidal Audio. This is by far the BEST electronics on the planet, and as you can see, I have slowly moved to an almost complete Tidal Suite. Sound is shockingly transparent and is glorious to listen to... Where will I go to next? Either try analogue (that I have been resisting) or find a good Computer audio system (that I am currently researching but can't seem to find anything on par)...
Italian furniture manufacturer (www.molteni.it). Not an audiophile stand but visually beautiful with superb finish. Pictured is the all aluminium storage bin that comes with the stand. Notice that a Acoustic System resonator is placed in the bin
Acoustic System Resonator
1 Platinum, 2 Silver and 1 Copper resonator. You have to hear this to believe these little jewels. Mind boogling amazing!!
Tripoint Troy
Amazing what it does to the sound!
Tipoint Orion
Master Reference A/C Conditioner. My system has undergone a magical transformation!
Orb Audio Kamakura Power Tap

Since you do not appear to be overly budget constrained why are you using the ud8004 instead of the ud9004? I own the latter and it is an excellent piece. Since all else you have is "best in class", why not go the same route with the Marantz. If you are using the universal player for 2 channel only (this appears to be the case), you could also get the new Ayre (10K), which is 2 channel only and allegedly the new SOTA in unversal players (stereophile review forthcoming)
