I need to fix the resonances in my room. Trouble is, I do not have the DP version so I cannot use REQ to fix the interference in my room. Should I upgrade to the DP? (where and how?, I am in the US) or should I just get a Lexicon? (I think the MC-12 has the Room EQ. Or is there something better? I really like the warm sound the AV32R produces. It has a really low noise floor and even when turned up all the way, I cant hear a thing (if there is no source of course). I dont like the idea of tubes and fiddling necessary to 'get them right'. I also would rather not add an inferior box to the audio chain. Any ideas?
