A friend of mine loves horn speakers but can't stand the erratic frequency response most of them have. So, he uses the Accuphase digital EQ to flatten the response. Of course there are newer less expensive models available from other companies like TACT now. But, it could be a way for you to keep the speakers you love and get better sound.
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).
