Just got back from auditioning the Naim DAC-V1. Spent a couple of hours with it and this is the best that I've heard the HD800 so far. The amp is very capable with plenty of punch and dynamics and the DAC section is out of this world. The combo provides plenty air and detail, punch, beautiful mids and to die for highs. Is it worth 2x the price of the WA7? That's very subjective and it probably isn't. Music is more engaging from bottom to top and a soundstage is out of this world. For me, this is an exceptional one box solution for the HD800. The plan was to add a tube amp down the road but from the audition, I may not feel the need. Only time will tell.
Don't get me wrong, the Woo WA7 is phenomenal and the Naim takes the HD800 to another level.
You've probably figured by now that I ordered one. Going to get busy putting the WA7 up for sale to help fund it.
More to come once I've had it for a few weeks.
