Tube Monoblocks in the 5-7K Range

Rogue also has the triode/ultralinear switching on the fly.

And if you look closely at the Stereophile review, it is suggesting that the Rogue has "the control" of a SS amp. Better control than a Pass amp? High praise in my book:

"The biggest difference was in the amps' control of the low bass, especially in rock and pop. The Rogue M-180's control of low-bass notes was exemplary, with great speed and heft, and the Pass XA30.5 simply could not complete in this regard. Through the Pass, the leading edges of bass notes were rounded, each note hanging over a bit too long."

Between triode mode and the ability to roll tubes you have some flexibility with the Rogue. And you don't have to give up some of the characteristics that are considered tubes' weak points.

But as alwasys auditioning in your system is far preferable. All about synergy with your speakers and your tastes.

I guess I'll need to find some place to hear the Rogues. I take any professional reviewer's review with a giant grain (more like a chunk) of salt - put more trust in the ears of end users like you guys, so if you're all saying the Rogues have tube warmth, I'll need to consider them.

I guess all these amps take a variety of output tubes that will have a big impact on sound in virtually every one of them.

The Rogue M-180's are very, very good at that price range. I would also put the Manley Snappers on your list to consider.

I have a pair of Cary 805C to drive my Merlin VSM 87 dB
Very powerful for 50wpc. Do a search online, Stereophile had several reviews. 805AE cost more but not sure it worth the money compare with 805C
I currently use them to drive my Usher BE20's top freq ( bi-amp with Class D driving low freq)
Good luck

The Quicksilver V4's are flexible in tube choices to tailor the sound. Hand made in the U.S.A and built to last. I would not describe them as overly warm, but if you want a creamy mid range you could go in that direction with a tube that has that characteristic. They can also use the KT 120 which is supposedly very nice in those amps. I use the JJ KT88's and find them to be very nice. Mike Sanders uses them as his premium tubes in those amps.
All of the amps mentioned by other posters would be worth auditioning. It's all a matter of system matching and taste. Good hunting.
