Buy a Threshold those Naks are great for the money but for another $800.00 you can have real real amp that will sound much better than the Nak or the Rotel. Here is a link for a decent deal on a Threshold here on audiogone. If that is too much money the second link is a great deal and for sure will sound better than the Nak, Adcom, Rotel and any other MidFi amp.
