Mark Levinson 27.5 vs McIntosh Mc-2500

I bought a pair of Klipschorn 17 years ago, I do not seem to be able to get rid of them for they are so incredibly good. I ended up bying systems around it. I am now running an AR Sp-4 preamp and a Dunlap-Clarke Dreadnought 1000 amp. They sound great but my local stereo repair shop complained the last time I took my amp for routine chek up. I now want to buy another amp. I have $2,500.00 disposed for an amp. I love McIntosh and Mark Levinson. I will be happy with either one but I want to know which one is better. I will take any suggestion including other speakers (I listen to classical mainly and occasionally use it for home theater).
