Yes, Thanks. I always wonder how these top drawer speakers pair with modest avr gear. Sounds like a person would need to upgrade their system to bear the fruit.

The new AL5 La Scalas are wonderful. My wife and I purchased a pair in 2019. We drive them with a Primaluna E300. If you enjoy Klipsch and tubes, this tandem is worth an audition.

He's using the single ended 211 amp on the right.

Both are outstanding speakers! I have tested The Kliptch Klipschorns flat down to 29 hz.

Hi Jeffrey, the K-horns of course have a folded horn bottom end, which results in sonorous bass with very little distortion, a big plus. But the horn is long, good for low bass but not so much for low midrange, so the mid horns have to take up the slack at a lower than typical crossover frequency. And the big difference in bass and mid horn lengths creates some timing issues at crossover that may be detrimental with some program material. Consider also that by design the K-horns must live in corners or have false-corners to complete the horn sidewalls. Based on my experience, I would recommend that you stick with your Cornwalls and spend some money on actively triamplifying them and burnishing their voicing with some DSP equalization. The results I'm getting with my Cornwall-like DIY speakers and active multiamping are beyond all my expectations, especially in the area of uncanny pinpoint imaging and soundstage depth. And I think they sound sweeter than these K-horns---if this recording is a faithful representation---but still very lively.

I've got a pair of Jubilees :)

Those speakers are 105 dB sensitive. Horn bass is very fast and controlled I believe, and most of the impact of it is probably lost via a mic.

Their efficiency is such that they hardly need any power.

You cant tell cos you are not in that room, if anything is lacking power it might be your set up.
