Have the DPS(desktop power supply)/UDAC/BUDA combo from Headroom. Started with a balanced AKG 701, and was quite amazed. Now just recently acquired the HD800, not yet fully burned in, and the cable not yet reterminated with XLRs for balanced feed.
Prelim: I love these HD800s! Agree with all of the above positive descriptions so far. The soundstage is big and wide. The imaging detail is better. The performance is another level above the AKG 701s. Perhaps not quite proportional to the cost ratio. Nevertheless, I'm, thrilled to own these, and I can't wait to hear them in Balanced mode, since many people suggest that there is a big difference for these headphones in balanced mode, compared to SE.
Does anyone know if going to a ~$300 aftermarket balanced cable such as those from APS gives a noticeable difference from stock cables reterminated with XLR connectors?
