Well , I took the first step , I've had an Arcam I-dock running in the garage for the past 30 hours . It does have a SPDIF digital output so a decent DAC will likely be next . Although , from the onset the sound was quite good , tinkering with some higher end RCAs that had been lounging around in a box for far too long , I heard one that was a match made in audio heaven , a pair of Vandenhul's . My yap was agape for three or four songs . I can't recall hearing a component that was so changed by interconnect's .
