***SOLD***  NOTE: I have another available for sale...
For sale is the Liberty Audio B2B-100 in very good condition. It is 100% made in the USA. This amp has upgraded binding posts and an upgraded XLR input (the one used for monoblock operation) is a high end Cardas connector. 
The B2B-100 amplifier is designed by Peter Noerbaek who owns PBN Audio line of high-end speakers and electronics. The B2B-100 amplifier has seemingly effortless power despite being rated at 110wpc into 8 ohms (200wpc into 4 ohms). It has a very clean and musical signature. The amp is fully balanced, with a unique High bias/Low bias switch. Should you wish to pick up a second B2B-100 down the road, you can use them as monoblocks as they are bridgeable. 
Price is $995 plus shipping within USA.
