Why nobody uses McIntosh with Vandersteen?


Is it a classic mismatch or what? I mean nobody recommends Vandys for Mac and vice versa. I love both brands but if I buy Vandersteen 3A Signature I'll have to start looking for amps. I once tried hooking up 6900 to 3A Sig's and on 4Ohms the sound was dead while on 8 Ohms it was alive but thin. Is it the autoformers?

UPDATE: I now change my McIntosh MC2100 (105wpc) to McIntosh MC601 monoblock (600watts) and a McIntosh C2300 tube preamp. It's jaw dropping, the Vandersteen really woke up significantly.
I noticed no one talked of pairing Vandersteen and Ayre. I personally like that combination.
I have Vandy 3A Sigs powered by McIntosh C42 & Mc501 monoblocs.Use the 4ohm taps on top,with 2 ohms to the bottom in combination with two stereo runs of Kimber 8VS speaker cable.I'm very pleased with the overall results.In my situation I find the choice of interconnects to be a huge determining factor in obtaining the preferred system sound.Currently using Signal Cable silver,but still looking for that synergistic match.Any suggestions from Mac owners are welcome.I contacted The Cable Company for their suggestions.They're all over the place with their recommendations.Now they say PAD Genesis(their only choice).Other times it's been Mit,Cardas,Alpha Core.Not sure what to make of these guys.
Denmaqn, I use Crystal clear Audio Cable for interconnect and get excellent result. Go to this site: http://crystalclearaudio.com/ and talk to Mel the owner 909-856-8153. You can also read on his excellent reviews. Highly recommended.
I think Lrsky probably hit it pretty well.

SOme combos are just not as likely to appeal as others.

ALso, I do not recall every seeing a dealer that actually carried both lines. I've seen may Mc dealers over teh years, and a couple vandy, including one local current, but never both together that I can recall for whatever reason, probably just chance.

Mc tends to be sold in more mainstream shops with some snob appeal whereas VAndy is more of a blue collar workhorse type line in general I would say.
