Where to go from Rogue M-150 amps?


I'm curious the hear the responses and opinions on this question. What would a be a good upgrade from the M-150s. I'm not really interested in the factory upgrade to the M-180. I'm currently using my 150s with the Perseus preamp and Vandersteen speakers. Overall, I'm very pleased with them. Great bass authority and control. The mid are good, but could be a little more fleshed out and intimate IMO. The highs and detail is there; however, more air on the top end would be a plus. I'd like to stay tube, but will consider SS. Monoblocks are desired but not an absolute must. The amps must work well with Vandersteens as they are my speaker of choice followed by Magnepan; but I will probably stay with the Vandersteen line for a while.

Thanks!

I use 2 Ayre V-5's on my Vandersteen's. The Rogue's are great but even 1 V-5 would be a big step up.
The M-150s have a retail of $5K. So, I would be looking for something in the $6K to $10K MSRP range.

As for power I would like 50 watts or greater. I have a small listening room; however, Vandersteens like watts.

Why would that even matter? Spend more just for the sake of spending more? I won't tell you what to do, but I highly recommend picking a new amp based on sound quality and not price. If you don't, you'll fail.
Is there a reason besides logistics that you don't want to do the Rogue upgrade? I think that would be the most cost-effective way to go. That and replacing the power tubes with KT-120s, which will give you more extension both on top and bottom. But if you don't have a dealer to go through, I can see why it might not be an attractive option.

I'd also suggest trying different 12ax7s to get a midrange more to your liking.
