Hello, I just received my Aesthetix Io signature w/ volume controls about one month ago.I'm still breaking it in. I have not compared it to the Lamm. I have compared it to the Steelhead.I have no problems with RF or excessive tube noise. Although, I am accustom to tube "rush" with systems I've had in the past. The Aesthetix is a liability in terms of shelf space and tube complement. The naturalness of presentation on my system with the Aesthetix edged out the Steelhead. I was willing to take the risk with the number of tubes based on performance.
Sounds like the Io, Lamm, Groove are all about being on a similiar plain with different trade offs..
Good Luck...AJ
