metalgear 0 Report post Posted November 5, 2011 ps audio GCHA is also a very good amp... much like the lyr, without the crankiness of the tubes. drives up to 10 watts so can drive akg1000 and speakers. best its a digital amp (like bel canto) and doesn't have the harshness that solid state amps can bring to cans.
