Hi Krellpower1; I've been following this thread with interest. My present system is all digital, and while not quite "State Of The Art", I think it is an excellent "real world" rig. It's taken me 7-8 years to get to this point. This spring and summer, I added dedicated AC and ground systems to 4 Hubbell duplex outlets, and Levinson 37 transport and 360S DAC to my Sonic Frontiers Line 2 pre-amp and McCormack DNA-2DX power amp. Speakers are Vandersteen 3Asigs. For wire, I use Syn. Res. Phase 2 ICs, Syn. Res. Sig. No.2 bi-wired spkr cables, and presently have Syn. Res. Master Couplers on all components. Yes, I like Syn. Res. products, and I intend to try their Reference power cords on my source components. I use a Cardas AES/EBU dig. cable between transport and DAC-- it is less detailed, but more musical than Madrigal's MDC-1 cable. As of now, I think my system has no weaknesses, ie it all works well together. I have 5 ASC tubes in my room, and I'm going to continue to fiddle around with tweaks-- just got two Seismic Sinks. Some might say this system could support better speakers (more expensive?), and I'm seriously considering Vandersteen 5s-- but this whole thing sounds so good that I'm in no hurry (and also broke). Cheers. Craig.
