mac and vac amps with thiel 3.6

Yeap. I had a Mac MC225 connected to the Thiels 3.6. It sounded horrible! Ended up buying a VAC Ren 70/70. What a huge difference...
Before the Thiels, my Mac 225 was connected to a pair of Kefs and it sounded very nice. Not sure if I was doing something wrong, but what I can tell you was that as soon as the Ren 70/70 was connected in the system, it completely opened up the sound. Clear, natural, wide soundstage. Liked the VAC sound so much, that I have replaced my preamp with a VAC Ren Pre, too.
Due (and only to) to space constraints I might end up selling the Thiels. Otherwise, nothing to complain!
Good luck.

Well, the 70/70 is way more expensive and way more powerful than the MC225 so I would hope you would like it better!

Garnetts - did you have the MA2275 in mind? I haven't heard it yet but am curious.

as has been pointed out before on the forum, Kevin Hayes voices and tests all his VAC products on the 3.6's he has at the VAC factory. i would say the VAC would be a safe bet with the Thiels.
