I like them a lot, though I slightly prefer the upper Prestige range (Kensington/Yorkminster SE). At under 10K, the Glenair 15 is a (relatively) great value. I'm a heavy drinker of the Tannoy dual-concentric kool-aid, so do keep that in mind.
A while ago I turned away from the compact towers/bookshelves; sure they can put out an impressive amount of sound "for their size", but that's too heavy a qualification to go with $$$$ hifi systems. Unless you always listen at low-moderate levels, you just can't do proper dynamics AND bass extension without a good size.
To me, the Glenairs are of a proper size for a hifi speaker -- and they're just incredibly well integrated from top to bottom. There's no hint anomaly or disjointedness from bass to mids, etc. That's one of the major contributing factors towards their musicality. The balance is excellent -- they shouldn't present themselves as warm nor bright/analytical. I think you'll be quite pleased.
Also take note of efficiency parameter -- at 95dB/Watt, the bigger Tannoys are a godsend for tube amp lovers, and I still think you'll reap substantial benefit with your beastly Pass amp. You'll certainly be spending the vast majority of your listening time in the sweet class-A part of their output. The Glenairs do sacrifice that last bit of bass extension for their 95dB efficiency (check out the Yorkminster for some amazing extension @95dB/Watt in a slightly larger package), but they're still leagues ahead of lots of hifi speakers having no better extension coupled with terrible (in)efficiency. I was shocked at just how significant a difference there was in the mere 2dB from my Kensingtons (93dB/Watt) to the Yorkminster (95db like the Glenair 15). It is QUITE audible! Going from 87dB to 95dB per Watt is like multiplying the power of your amplifier by 6.4!
