Bialbero Quattro V should be announced in July 2014 and 4 pieces of AA batteries required
I can concur with Rudi. If you have the 385, there isnt a great need to change to the 395. The low gain switch pretty much eliminates the hiss but there is a slight tradeoff in terms of power. Switch to high gain and it pretty much is like the 385. Some say the 395 has a slightly bigger soundstage but I didnt get that impression.
Wagnuis in term of SQ is my best Portable amp , i hope this new Quatro V Amp Sq is better tha Wagnius Epsilon S
Did you tried on Mook this new Wagnus Amp?
If I am not wrong, Wagnus brought only one unit of the Epsilon S Mad-Bk to the recent Mook Festival in Singapore and Sid must have bought it on the first day. It is basically a standard Wagnus Epsilon S with bigger battery capacity. There could be some internal changes that I am not aware of. But it is rather surprising to find sonic differences between the two amps.
Rudi, from my discussion with Tone Flake at Mook Festival, the bigger Epsilon is supposedly the better amp. He gave me the impression that the sound quality is better than the Epsilon S. Too bad I did not get to compare the S Mad Bk with the standard Epsilon S.
On another note, have you tried comparing the Wagnus Epsilon S with the stack consisting of ALO RX MK3 B + Venturecraft Go-DAP DD Ltd 12v + Ipod Classic? Since you have these devices, it would be interesting to hear your comparison
