Tube Amps With Good Bass Qualities

VAC.  Years ago, I heard a pair of the early PA-90 monos producing prodigious, authoritarian bass from Apogee Stages, which didn't make a lot of sense, but made me a VAC believer.  PA-90'S can be had for around $2200 a pair.

I guess a better way to ask my question above..... how to match a tube amp to a speaker, is one to find what the lowest dip in the speaker measurement and make sure the amp can over come that dip rather easily ? 

Right @stfoth, the SVT. For reproducing bass, a second for the RM-200 Mk.2. I didn't want to be the first ;-) .

br3098, that’s flat out wrong. If the speakers can handle < 40hz but the amp can’t, then you’ll never hear it from the speakers

Gfi’s suggestion sounds good; a pair of Shitt class A amps (~$1600), however, class A runs hot, burns a lot of electricity...

I have owned fully balanced all tube systems and good though they were, plumbing the depths was a weakness, which is why people use them on highs and mids and SS for bass. In fairness to Ralph/atmosphere, I never had the pleasure

However, I recently purchased a EVS 1200 (600 wpc) from Ric Schultz/tweakaudio. (I know what you’re thinking, but my current and future speakers are 93-96dB efficient.) It’s only got about 100 playing hours on it, but it has that inner musical detail magic that for the most part HAS BEEN the domain/allure of tube amps, but it also has gorgeous mids, lower mids and excellent bass; more bass then my speakers can project with a low end of 42Hz. I have new speakers on their way which will resolve that

It’s fairly priced at $2200, idles 24/7 at 57watts, and likely sets a new benchmark for price/performance under $3K, although... (cliff hanger)

The EVS 1200 comes with a 30 day guarantee, so nothing to lose. Mine’s not going back

Another vote for Manley or build a pair of VTA M-125 monos.
