I ended up with a Musical Fidelity A3CR when looking for the best for the price of dirt ($600 on ebay) and am still glad I did.
The Best Amp for the Price of Dirt
The Berringer a 500 Reference Amp that can be purchased on Musican's Friend web site for 194.00( each) to your house in the US of A w/ a 2 year warranty is a KILLER. I have several amps and these are scarey. Granted they were designed overseas & built in China... However, they are 19lbs GIANTS . Don't take my word go to the "Audio Critic" web site for a full review. This is my one an only give-away . Use it or loose it. Best to 'All
