Best tube amp s for magnepan 3.6r


I have a pair of 3.6r's. I am driving them with rogue m-150 mono amps. I think I need more power, but would like to stay with tubes. The system is used entirely for vinyl and the preamp is a CAT SL-1.
Any recommendations?

Are you still satisfied with your choice of amp for your maggies? I have a pair of 3.5s and I find my Bryston 3b SST is underpowered. I was going to go Bryston 7B SST but have heard they may be a bit dry for this speaker. The VTL was on my short list. Other amps I see recommended such as the Wolcotts are a bit out of my price range (under $5000).
