Tube amps vs solid state for large speakers

You might consider the Rogue M-150 mono blocks. 150 watts ultra linear or 90 watts triode. They are made in the U.S. and their customer service in very good. I am using with Martin Logan Summits that dip to 2ohms and are 90db. Used they are just a little over $2,000.

Thanks for all your responses. It seems that my speakers are efficient enough to run with lower wattage amps from what I am gathering here. Anyone have any experience with the AES Monoblocs? I saw a couple on the gon here recently and they seem interesting and good price point for tube amp entry. Also, anyone have any experience with older McIntosh tube stuff or should it be avoided due to age....

I haven't heard the AES Sixpacs but had an AES AE-25 Superamp, the DJH signature version. Great sound for the money, not the last word in tube warmth but more on the neutral side and good bass. The fun thing about the Superamp was trying different output tubes. I ended up trying over 20 types of tubes, each of which significantly affected the sound. You might be able to do this also with the Sixpacs, which have more power output and probably better bass.

I would think with those specs and assuming a smooth impedance curve that 60 tube watts would be plenty of power to drive them as loud as I would ever want to hear them. That of course opens up a much wider selection of choices - though I could hardly recommend a better value with great sound than the Music Reference RM9MKII previously mentioned, or the Quicksilver V4s if you want a little, tiny bit more margin of error over 60 watts on ultimate volume. I run my Merlin VSMs (89db, smooth 8ohm) with 30 watts integrated tube - no volume issues.
