Tubes on Proac 1.5's

Used Rogue Magnum 120. Absolutley great match. Affordable This speaker needs alot of current and headroom.
I am using a An Audio Research VT 100 MK II with the Proacs 3.8 and I love it. I was orginally using a Bryston 4B ST and thought it sounded harsh with these speakers.

I just borrowed an older Sonic Frontiers 40watt tube amp and my wife and I are stunned by how much "percieved" power this amp has. The Classe' is more refined with more bass slam but the tube sang along really nicely.

I must learn more......

Thanx for the replies
I am using a Sonic Frontiers 80(KT-88's) and an Audible
Illusions pre, I love this combo. My speakers are the Responce 2. What I noticed a real help is a subwoffer. I do not know how much room you have aviable, but if you can stick a decent sub in the corner it will make the music bloom.
The bass is really quite acceptable with the sfs 40. Now I don't know which way to turn.
