Kat88 is it any good?? with Klipschorns

[Grog]

hi,
i'm looking for a good valve amp to try with my newly aquired klipschorns.
i've seen a KaT88 for sale at a reasonable price, but i've been reading up about a few problems people have had with this amp.
I don't need huge power (althought he klipsch are 16 ohm i think, so voltage needed)
would i be better off with a secondhand maplin 4-20 (with upgraded optx's)
or a secondhand kel84.
they are all in a similar price point secondhand.
to me the bass is very important, the klipsch have excellent dynamics and depth, i don't want to lose that.
i have no problems at all building my own amp, have scope sig-gen, b&k mic etc

but it seems to be cheaper to buy a secondhand kit. funds are tight, as i've just got the khorns and don't know if i'll like a valve amp.
