CJ PV-2ar or PV-7 or ARC SP-6 for Klipsch Heresy?

I putting together an old school tube-based system to drive an unmodified pair of Klipsch Heresy 1 speakers I picked up on eBay.To give the "old school" a fair shake, I'll be using the best ancillary equipment and tweeks, Transparent Ultra signal cables, and MIT power cables and filtration, etc. Seems to make sense to me to pair them with one of the classic tube preamps of that era such as a PV-2ar, certainly might tame the brightness and "shout". Thoughts?

If an original set, you really want to think about a tube amp too- the crossovers in that speaker don't work so well with amps with a low output impedance- as a result the horns can be operating out of band, part of the reason for the 'shoutiness' or 'cupped hands' aspect for which many older horn systems are undeservedly known.

I'm pretty sure the Transparent cables will not be a good match as well- they work better with solid state.

Why those particular preamps?? Just because they are tube?

A cj might have too much gain to use with high efficiency loudspeakers.

But to say that the noise floor of tubes in general is too high for speakers of 100 db or more is untrue. The proof of this of course is that most horn speakers are used with tube amps, not solid state. My speakers are 98 db and I have to put my head in the mouth of the horns to hear the noise floor.
