Home Visit: La Scala redux

I should have done this much earlier, but fortunately it's never too late. Quite a long time ago I met conrad2002 and learned that he, like me, is a Klipsch La Scala user. Recently I called him up and he said his setup does not sound good. A few days ago, before a group visit to Andy L and Simon in 錦繡花園, Andy L and I paid him a visit and instantly proved that he was far too humble. Setup:

Digital: Metronome
Preamp: Pass Lab
Amp: Sun Audio 2A3 using Full Music 2A3 and GT 6SN7
Speakers: Klipsch La Scala (later non-alnico) with midrange horn replaced by EV; Tannoy "supertweeter"
Cables: All very cheap

Once again, it proves that the La Scala benefits from corner placement. The corner is part of the folded horn we should remember. The bass is excellent, full and agile. Many years ago, Leo Fung in 音响之路 advocated the use of 10 tricks to augment the "insufficient bass"of La Scala, but that was only because he had the speakers way into the room to get more "soundstaging".

The simple but effective setup has stunning clarity and presence factor. With full-bodied sound that sounds like the musicians are in the room one does not even think about artificial soundstaging. I am convinced that the Electrovoice horn contributes a lot to this great sound. The horn is unusual in that in addition to the direct front-firing central small horn, the back-firing sound is directed into the larger outer horn. driver (I should mention the same La Scala midrange compression driver is used). The "percussion" Carmen was sonorous and crystalline in clarity. The midrange is very slightly lean on vocals, possibly due to the ss preamp, but no mistake about it, the setup is marvelous and what a horn setup should sound like! With an efficiency of 104 db, I doubt the lower-efficency Tannoy tweeter is making much sound at all.

A humble system that puts many hi-end setups to shame. The Persian is just as lovely!
