Gallo Reference 3 vs. Spendor S8 vs. Harbeth Super

You'll need a good sized room for the Harbeth; it's a big speaker. I've heard the Gallo at a dealer and thought it rather bland and boring but it may have been the other equipment in chain.

I think the HL5 is in the same family as the Compact 7 (which I have) and that would make it very musical with a clear, open, but easy midrange. You can check a back issue of Stereophile from this year in whcih Sam Tellig gives a pretty good description of the HL5. It will be a very different sound than you've been getting from the Klipsch.

I went to the Gallo when I went to a small room (there was not enough distance for the sound from Dunlavey SC III's to integrate properly).

I am surprised at Tomryan's comment about bland & boring, I have found this speaker anything but that--in my system, my room, my cables, my music (mostly jazz & blues) etc (details listed elsewhere).

"accessories" are also availabe: I have mine on IsoRock GRIII stands and just added Gallo's sub-amp...

Gallo Ref3's were fantastic the week I had them to demo.
They do take some correct room setting up,but when locked in they shine.
I do prefer them with woofers out,and 36" from back wall,and facing straight foward,with about 1/2inch front raise for my room...15x21 listening area.Towing them in about 1 or 2 inch makes them more focused if you like a small club effect.Imaging is unbelieveable. For the price its a no brainer.
I am waiting for my dealer to get in the Spendor S8e for a demo.But think the Gallo's will be better.I am not fimilar with the Klipsch.
There is a company called Bright Star Audio www.brightstaraudio.com that make special stands for them to add some height to them.Side wall placement of speakers is important and the starting formula is (room width divided by 18 then multiplied by 5 and then multiplied by 12) which gives you starting distance in inchs to center of speakers.
