I would agree at times the tweeter can be a little harsh in mine and supoose that what I am trying get away from, I have'nt heard a lot about Mcintosh are they any good as I rememeber sombody bagging them once,that has stuck in my head for some reason I normaly dont try to think that way,
McIntosh on JM Labs is always magical. I have loved that combo for years.

Can McIntosh can be converted to 240v what are some models to kept a eye out for.
