Interesting read, I never heard this specific set-up but look forward to hearing it at RMAF. Appears VAC will have some competition because there will be another pair of Grands paired up with another manufactures gear.
I'm a proud owner of VAC Statement 450's along with using their Sig MK2a pre paired up with my MBL 101E's for a few years now so I'm very familiar and very happy. I'm really looking forward to hearing along with any other manufactures speakers paired up with the VAC gear in general - curious you know. My speakers list for around $70K now and these Grands list for $195K so one would expect that they should put mine to shame. Should really be comparing MBL's Extremes considering all things.
If they do I'll be looking into getting a pair ;-)
I have only heard the Grands once with Devialet electronics and was left very disappointed scratching my head, I have heard the Stella's on numerous occasions with different electronics and most recently with Rowland 925's with same Vac Sig pre as mine but reading above numerous comments mirrors so far my findings. Apparently the Grands are suppose to be in a whole other league in comparison to the Stella's but this depends on who you discuss such with, sure list for allot more.
Anything I write is only my opinion and others may differ, I know shows are far from ideal but at least the tonality should be there. This is crazy money when you look at the complete package so it brings high expectations as it should.
I get tired of when I hear excuses from these show attendees, come on guys set-up your room properly - start by bringing a system that is fully broken-in - step one. I swear some just use this as a general excuse. If you aren't skilled enough then hire someone to do the set-up, bring this or that to assist in taming the room - use the same room over again and again. After two shows if you haven't figured it out what can I say
How many of you guys have gone into a showroom to hear this and that, the set-ups are usually never that great - have you ever asked your self why? Your happy to be back at home listening to your own.
