I'm looking to buy an Arc Audio XXK4150 & XXK2500. Must be in good shape and also have some items to trade if interested. Items for trade if interested include the following:

MB Quart RAA 4200
MB Quart RAA 2400
Focal 165 K2P
JL Audio 450/4

The amps are in excellent condition and in the case of the MBQ's are NIB. The Focals are also in great condition. email me at krivera77381(at)gmail.com if you have something.
