In order to keep myself occupied in middle age I have decided to try and find the best (affordable) hifi amp of the Millenium.... So from the last 20 to 30 to years or so. I have had several amps over this period, most now have been resigned to hifi heaven....but I still own a Denon PM720AE, a Yamaha A-S501, Cambridge Audio Topaz AM5, and have just purchased a Rotel A11 which is my daily listen. I have dug out my old amps and have today derived considerable enjoyment from testing them all (in my garage) in conjunction with some old, but beautiful sounding (and looking) Ruark Talisman ll's which I recently bought for less than £100 on ebay. What I am hoping to do is test affordable eBay amps, so second hand (BTW, affordable for me is under £500) then sell it on and buy and test another, or maybe keep 2 at a time for comparison purposes, then sell the least favourite out of the 2. Please let me know your thoughts, specifically your favourite amps which I may get for under £500 on ebay, or from anywhere else that sells second hand or reconditioned gear. Thanks
