Excellent all in one unit from Burson audio. Right now these are onsale for 460 with the standard op amps plus another 145 for the pair of v6 dual classics and another 90 for the pair of v6 single classics so almost 700 usd new plus shipping, so save yourself a little over 200 dollars on this deal. If you have wanted to try a all in one from Burson this is such an excellent little unit and with the upgraded op amps makes for the perfect small setup. Smoke free home and shipping/paypal included in the price. I am trying to bring a decent deal so others can get a chance to hear equipment without breaking the bank. Pm with any questions or offers.
