Hi, Funny I have the Snell AIII's and have just replaced my BAT VK 500 with a Plinius SA MkIII. In my case both amps sound fantastic but different, The BAT clean and precise with a little forwardness, The Plinius a more musical approach and a little more laid back. The surprise to me was the fact that the Plinius although not nearly as powerful has such a better grasp of the woofers providing a great low end slam, which is important for the Snell 12" woofer. Either way I defy anyone to find a better speaker on used market for under a grand that sounds even close. Good Luck.
