Sonus Faber Guaneri Homage or Extremas?

Mal, please do tell us what you think of the two...However, please remember that the speakers will interact with your up-line gear and that this will, IMO, color the speakers in a way that you may or not like. The Extrema's need a lot of current to shine, the GH's less so, but still need an amp with good stick up front. My main point is the synergy with your other gear and room, is going to be a factor in your opinion of the speakers.

Interested as well !

Have the Mc352 amp working with Mcd500 and all connected to xlo cables. Thinking about changing the Mac amp but want to stay with McIntosh, any suggestions?

So how is it? Extrema or Guarneri Homage.

Mal, I personally do not like the match-up of Mac gear and SF, particularly with the GH's or Extrema's. The only possible exception to that is the Mac 275 which, while not IMO a great match to the GH's,is the best of the Mac gear I have heard with these speakers. With the Extrema's the 275's are, again IMHO, not powerful enough to really drive them and so I have no Mac suggestions for those.
