high power tube amps vs ss

Schubert, even if it's not NOS, the high-powered amp uses 6...12 tubes per channel averaging $20 each.

Agree with Phaelon, the speaker's load characteristics(impedance curve-fluctuations and phase angles) will determine if tube or transistor amplifier is the best option.

Along with Isochronism and Larryi I much prefer the lower power amp with high efficiency speakers route for the same reasons they cited.

The best amp is the one which is most synergestic tube or SS. I prefer tubes but one system I have sounds best with SS. I have tubes in other systems which are also magical. Try both tubes and SS. Carver and Manley, ASL Hurricanes are all good top fuel choices. Tubes will seem cheap to a transistor replacement and they do have a lifespan. A friend had his Krell mda 300s repaired...3k. 3k buys a lot of tubes, no free lunches. I prefer high efficency speakers. Pick your poison..... Jallen

In 48 years of using solid state amps I have never had to replace a transistor...
Total of parts was one blown cap.. in 48 years..

“My questions is: is there anything to be gained by switching to these higher power tube amps over ss amps?”

Tough question. It kinda depends on what a person wants from his or her system. Each type of amp has it advantages and disadvantages. This subject debated countless times here. Spend a little time and search the forums and you will be rewarded was plenty of SS vs. tubes thread. A seatbelt may be required.
