Old tube versus new tube gear

I think newer tube gear in general sounds more neutral and is better geared for those who listen to a broad range of music genres and vintages. That makes it more versatile I would say! More vanilla. Older tube gear, in general, is more "flavored". Age of the item and overall operating condition accordingly is commonly probably a significant part of that in practice.

Al,

I'm curious if in your opinion, the old Brook amps, assuming in good modern working order, could match the performance their more modern equivalents overall, particularly on newer recordings of various genres that are digitally mastered? I'm sure the exact kind of modern speaker used would be a big factor. Not just any would probably do.

I guess my question might be rephrased. How much better are modern SOTA tube amps than their ancestors? And also how much should/does it really cost to play that game these days?
