Seven of us gathered at my place on Saturday to listen mainly to the Orpheus headphone. We had three HE90's and an HE60:
However, the star of the show was the prototype of a new amp by Headamp.com based on the HEV90. Here, Thrice listens to the new amp (the circuit seems to be complete, but the amp does not yet have a case):
This is a two-box design, with power supply in one box and amplifier in another:
Here's the power supply:
And here's the amplification section. Note that this amp uses the same tube complement as the HEV90 (2 12AX7's and 4 ECL86's):
One of the objectives of the meet was to compare the prototype to my Stax SRM-007t, which included the resistor in the bias line:
But I've got to admit that the prototype amp was the one that got me dancing (particularly to gpalmer's Bob Marley disc
):
I'll post a bit more about the sonic differences in a bit.
