Headphoneus Supremus
The information I have gathered on this amp is that it has sockets for changing out op amps and buffers, can use up to 15 IC's and puts out a little over 2.4 watts per channel. It is a quad design (all channels are separated) with a layered board having copper traces that are gold plated. The size is about the same as the iRiver H140 or 100mm long.
The PB2 is 12.6V when single ended, and it is 25.2V when balanced (swing). Run time is around 15 hours but varies widely depending upon what op amps are chosen and if the buffers are bypassed or not. There are many choices. The volume control is a custom ordered Alps for extremely close matching and is further checked to insure a extremely close tolerance with rejects being tossed.
