Vandersteen Aficianados please step inside (Quatro)

Yes, no problem! Get a pair of Dynaco MkIII's. These are great sounding tube amps built with excellent iron.

He might already own the 60 watt amp that he's referring to Jason.

So, despite the somewhat low sensitivity ,these speakers are an easy load. The bass is handled by a separate class D amp thats in the speaker so you're really only driving the midbass up. I've not tried it but I suspect you'll be fine. You can call Vandersteen and ask. They'll probably put Richard on the phone. 

If you are looking to get something new, the Belles Aria seems to be getting a reputation for being a good match. I use the dual mono 85 watt x2 with the Quatro. Not a tube amp and not the one you mentioned. Apologies, if I’m off topic.

@ozzy62 - get an amp that offers negative feedback like the Ayre amps do. That is what makes them shine. The 60WPC is plenty. I drive mine with our Class A mono block amps 40wpc. I also have driven my Sevens with a 28wpc power amp.

Call John Rutan at Audio Connection in Verona NJ he knows what will work.

Happy Listening.

Thanks for all the input. I ended up going in another direction and bought a pair of Verity Audio Parsifal Ovations.

Great speakers and certainly tube friendly.  Enjoy!  Verity will be greatly missed.
