I just reduced Meze's stock by one. A shout out to Vlad from Meze tech support who answered some questions and helped me with my order!
I don't have the Abyss but have the LCD-4's so will post my impressions of the differences between the two driven with a balanced (BTG...formerly Q...Audio) cable, using a Cayin iDAP-6 as a source for a Schiit Gungnir Multibit DAC and Mjolnir 2 and some very rare Lorenz Stuttgart PCC88 3-mica tubes.
I let you know when it arrives and post impressions after a little burn-in time and comparison.
Cheers and Thanks Meze!
