All vandersteen users ?

Amps hit their sweet spot at differing points in the power range. I have a pair of Vandy 2c's that I ran with a 250w Bryston amp that was as sweet as it got in my listening room. I tried a pair of ASL Hurricanes with the Vandy's and even though it had more headroom the sound was more muddled, less defined and less dynamic. When the cost of the added power is figured in the choice is clear. There may be many reasons why the single amp works better in my situation, many have been mentioned already by others.

BTW the Hurricanes worked like magic on a pair of Alon's that I have, one of the most musical sounding pairings I have ever heard.

The Quatro VK-55 mono blocks would be a fantastic combo!!! If you can do this do it and forget playing around, you would have to add a pair of 2Wq sub and all the associated equipment to come close. I had 3A Sig's, a pair of 2Wq's, M5-HP filters etc. etc. I drove this with Pass X-150 (pre- subs), Quicksilver V-4's and ARC VS-115 (could have used a pair of ARC VS-55 like Vandersteen did at shows with Quatro's) With the 2Ce Sigs2 and no subs I think you need min 120 tube watts per channel to get punch in the low end.

Samhar,

Tks ur response. Suprised at ur comments as dealer mentioned that 110wpc w the vk 55 monoblocks r definitely way underpowered for the Vandersteens quatro...

No chance for audition :(

Go to the Vandersteen website then to the Quarto wood page and view the Qutro's and ARC VS-55 at a show!!! My Vandersteen dealer drove his home set of 5A's with VS-55 mono blocks. The Quatro and 5A's have their own internal bass amps driving the woofers (As Ecruz stated), you may personally like more power but it isn't "necessary". The SPL that you listen at may be a factor, if you can afford 100 +wpc mono blocks go for it they'll be great but if your looking at a reasonable output of cash with high return the 55's are the call. I think something to keep in mind is I don't have a horse in the race like the dealer may, something I have to remind myself of constantly when I'm speaking with a dealer!!

I'm not a Vandersteen user. Vandersteen recommends between 40-160 Watts into 8 Ohms for these speakers. I would humbly suggest you lean more towards the upper end rather than the lower end of this range.
