I have been making small payments for a mid 90s YBA 2HC amp (used) since last month. I should be getting the amp early next month. It will be replacing an 80s Luxman M-113 amp in my system. YBA is high end and makes their own parts for their amps. Very robustly built. I had the chance to audition one of these amps in the mid 90s and it impressed me a lot. Im hoping this little amp will put an end to amp buying for my main system. These amps have great dynamics, are very musical with great imaging of sound, and is the only amp that passed my one song test I use when listening to gear. Anyone here have any luck ever hearing one of these amps?

Well after making payments on this amp for 2 months, I finally got it home today. Hooked it all up and its sounding nice. I didn't crank it up just yet, since its late here. Now I can concentrate the rest of the year on getting that new job and working more on the bills.

A symmetrical design, completely seperate power supplies for the two channels, custom made 1W 1% metal film resistors, polypropylene copper capacitors, absence of resistors in signal path, output transistors mounted on mica and copper to reduce capacitive affects, and cabling is pure crystal copper. My amp is the high current design.

70 watts into 8 ohms (230V line power)
140 watts into 4 ohms ( " )
Distortion <0.09% from 20hz to 20Khz
Frequency response 5 Hz to 80 khz at -3db
Rise time 3us at 10 khz.
Unweighted S/N ratio: >100db
Input impedance: 27 k Ohms
Input Sensitivity: 1.1V at P max
Damping Factor: >400 at 100 Hz
Power consumption: 100 VA, at P MAX both channels driven: 660 VA
Weight 13 kg

And though this amp is not that big, it weighs a ton. The power output is sufficient for small bookshelf speakers. Its the sound Im after.
