why are tube amps sporting such low RMS numbers?

[Guest105]

According to my local tube guru, the conducting medium in tubes is - air. In transisitors it's semiconducting solid material. As in solid state? Quite a bit different in electron efficiency I'd think. But real, actual, RMS ratings are thing of the past seems like. Chinese ratings have little to do with RMS. The old saying goes that if you want your solid state amp to have a tubelike sound, turn down the treble. Might be some truth to that in some cases.

What do you mean by electron efficiency?

The poor little electrons navigating that crystal lattice have it kind of tough. I know one man's vacuum is another man's sewer, but it is called a vacuum tube for a reason.

As an aside: it's rather amazing all the crap that actually comes out of something seemingly clean under high vacuum conditions.

I would run away from that kind of "guru". Their existance is why hi-fi audio gets bad reputation among general publuc.

LOL at that clip from "Ruthless People".

At least OP knows that his "comfort level" is around 80 to 90 dB. His ears will thank him for that. I actually think he should invest in some Klipsch Cornwalls and a 100W amp (a good one). It's not all about power. It's about efficiency. Cornwalls could easily get louder with way less power.

It's about both, power and sensitivity. They're equal factors up to a point.

I don't have the physical space nor the proper layout to use (typically) pretty large, high sensitivity speakers in my living room. But I do have room and a layout conducive to powerful but relatively small amplifiers and relatively thin lower to moderate sensitivity tower-type speakers.

Much of it is simply what works better, or is practical, for the space you have to work with.

Found a speaker that might go well with the OP's Pyle amplifier and listening habits .

I've restarted my tablet just too see what pic you posted, I keep getting q blue question mark!
I cannot see it. I wish I could tho.
