Red,
Have you ever heard a fully modded SB with the ultimate power supply? I was skeptical at first, but after hearing it I was convinced. I had been on the DAC merry-go-round for years using DACS from Camelot, Bel Canto, Krell, Audio Alchemy, MSB and transports from Camelot, C.E.C. Denon. In addition, I had a Consonance SACD 2.0. Originally, I got the SB just to play around with, but after getting the mods, and fully burning them in, I sold my DAC, transport and SACD player. And, yes, I did try the modded SB through the Camelot DAC and the DAC's in my Anthem D2 (I have the full digital mods also). The question is do you want to put $1500-2000 into mods or go the DAC route. If you’re set on getting a DAC, them I would recommend that you get the modded Elpac power supply and just the digital mods (about $550). The stock switching power supply in the SB is really bad.
What we can agree on is the incredible convenience of the SB. I have over 2000 CD's ripped in lossless, using a dedicated computer just to run the SlimCenter software. I constantly find myself rediscovering my music collection. And, I can find any CD or song in my collection in seconds; no more digging through racks of CD's. I was using a Nokia 770 to control the SB, but I just got the new Duet. I purchased the Duet just to get the remote because I couldn't wait for it to become available separately in 30-45 days. I've played around with the Sonos remote, and while I do like it, I wish it was a little smaller, lighter and that it had a touch screen.
BTW - I have a dedicated listening room that's 20 x 18 with cathedral ceilings. It has been acoustically tuned with the help of Rives audio. My current Loudspeakers are Martin Logan Vantages.
