My recently acquired McIntosh 225 literally obliterates anything else I owned prior. It made the Mjolnir and BHA-1 sound mid-fi within the first seconds of listening. I can tell you it was a pleasant surprise, my HE-6 are scaling a level above my HD800's right now; plus they're not aggressive (and this is with LCD3 pads which open up the sound but brighten things up because of loss of bass).
Would you kindly post a pix of your Mcintosh 225? Using speaker taps? Thanks.
