All vandersteen users ?

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.

Vandersteen speakers are capable of extraordinary performance. Even more important than raw power is quality of upstream components. Your best bet is to bring a pair home and try it with your stuff in your room.
