I currently own a Musiland 02 US DAC and a mini3 amp. I've been thinking about upgrading for a while and have heard some good things about the ODAC/O2 combo. I was wondering if anyone can shed some light on whether it's worth upgrading to the said combo. I plan to use it with the Denon AH-D2000, Sennheiser HD555, and Aurisonics ASG-1.
On a related note, does anyone know when the ODA (objective amplifier) comes out? If anyone has heard it, how does it compare to the O2, and is it waiting for?
