Klipsch vs Infinity

As oddiofyl said, the Klipschorn is fully serviceable. Repair and parts are readily available. As far as the serviceability of the Infinity Irs Gamma, good luck with that. Besides that, I would still choose the Klipschorn. If "X" dollars buys a good amp for the Infinities, then that same amount will buy an outstanding amp for the Klipschorns.

Elizabeth, Agree to disagree.
Charles, Agree.

I owned IRS Gammas for several years.  Arguably the best speakers I have owned.  While the do not have the sensitivity of the K-horns, they will in fact play extremely loud.  The servo controlled bass is the best I have ever had in my room.   Reason for selling?  Just like everyone else has mentioned...servicing.  I had to re-cap the servo controller.  Even after that, it still drifted in and out of calibration.  I am knowledgeable to service and calibrate it myself, but still a PITA.  The coating on the EMIM magnets was starting to peel.  The L-EMIM is unobtainium (or really expensive if you can find one).

I have heard the K-horns on occasion.  They sounded ok.  I owned Klipsch Quartet for a year or so in my second system.  I never really got into the Klipsch house sound and greatly preferred my vintage ADS L710 I have owned for 35 years or so.  But if you are into horns, I think Klipsch are a very good choice.  I think 17' is too far apart.  You would probably be better served with Cornwalls or La Scallas. 

Just my $0.02 coming from a die hard planar / dipole fan.

Infinity just killed the entire EMIM making.

True. they haven't made any in years.

Even when great replacement diaphragms were being made in Australia, The folks who bought out Infinity stopped them with patent infringement.

Absolutely not true, as verified by Graz, who makes the diaphragms.
