Thanks, all. 213runnin: The signal chain in question is Superberry DAC (a highly modded Beresford DAC) > MA3 (w/ Eichmann Copper) > McIntosh C220 pre > custom Litz RCAs (also w/ Eichmann coppers) > Vandersteen M5-HP crossovers > Odyssey Audio HT3 amp (w/ cap upgrade) > Ohm Walsh 2000s and a pair of Vandersteen 2Wq subs. The only thing I changed was the IC between the DAC and the pre, so all of my impressions refer to that change only.
initforthemusic: Thanks, I looked at the Cullen web site. Not too much info on the cable geometry, which, I think, matters. Is it stranded wire?
In any case, I will continue to try and put more hours on the MA3s, and try swapping the Monster back in once my friend applies his magic fix, and I will report back.
