Had one of these and want another, it's an amazing sounding unit especially with the right tube. I like the IEC Mullards, RCA, Raytheon etc. each tube changes the flavor. It is a more refined version of the smaller TA-01 which is not as accurate but still fun. Good review!

Is this better than Dark Voice?

yeah, really a great all in one tube amp, wasnt expacting that much clarity and soundstage improvment. Unfortunately, i'm still waiting the tube I order wich is a Mullard 12AX7...would have love to have more tubes to test for the review, but its the start of a new passion, tube swapping after OPamp swaping.
