I bought into the Senn. drop last month, and am considering this amp. If I'm guessing right, at 320 ohms, the Senn. 6XX, with this amp, ought to be good for about 120 db. Does that sound reasonable? And the one thing that makes me consider this, is that Cavalli put his name on the amp. He would look mighty bad if this thing is a turd. And I know turds. I bought a Pulse. Now, how about a killer ladder dac with a built in power supply? And a nice LPS for the CTH? Or an LPS that would power both?
