@murali-reddy I have a C22CE from the late 90s together with an MC275 Mk4 from 2002. on my 1977 LaScala it can sound very fine and subtle, but if I want it and the music suits it, I can create naked raw scary acoustic violence with these amps. very dry, fast and explosive even in the bass also as you say not too deep but anyway. Maybe the LaScala aren't properly broken in yet if you've been listening to them for 300 hours but quietly?   I restored 51 year old Khorns this summer. They now have brand new all original K33E Klipsch/Eminence woofers..like in your new AL5. Believe me, it took a few weeks, say two months, before they sounded completely resolved, clear, authoritative and well defined. I also only hear the lowest octave really energetic and deep after this break-in period. Give your AL5 some time and occasionally play louder music so that the bass can settle in properly. BTW I guess you checked all wiring, also the AL5 internals for correct phase?

Hello All.    Thought I should give you an update.   I've gone to four Jubilee dealers now.  While they currently do not stock the Jubilees the only stereo shop that was able to give me an excellent demonstration was Audio Classics in Binghamton, NY where they had them paired with double mono McIntosh MC 275 tube amps. (Thanks for introducing me to them, (Ryan K at Audio Classics, Binghamton, NY).  I just bought consecutive serial numbered MC-275s from them.  Since my memory could be faulty from back in May when I was at Audio Classics and wasn't ready to change my speakers out, in the end I had to go with wheat I could hear today.  I really think that had I been able to hear the Jubilees properly set up with tube amps again I might have gone in that direction. I'm getting Classic Audio (not to be confused with Audio Classics) T1.5 Reference speakers in their Contemporary line.  They sounded wonderful at the Capital AudioFest.   John who makes these speakers near Detroit one at a time hopes to have them to me by Christmas with the veneer that I was able to choose.  He's going to drive them out (about 9 1/2 hours away). get them upstairs and set up.   https://classicaudioloudspeakers.com/cgi-bin/index.pl?fs=2&upper=38&content=39    Thanks to all on here who guided me on here.    More detail for those who want to hear it all.   The Jubilee dealer nearest me (I'm in Saratoga Springs, NY) wasn't able to set them up with tube amps.  I think their showroom may have been less than ideal.  Not much side wall interaction.  speakers weren't in a corner.   listening position may have been too close.    I looked into to going to the HI Fi Loft in New York City to compare the K-horns to the Jubilees but because they mostly sell to New York City people (with size constraints) they don't carry the Jubilees, Just the smaller Heritage speakers.   Dealer in Chicopee, MA. would have loved to sell me their 75th anniversary pair of Jubilees.   But they weren't able to properly demo them for me.  They have them in their main show room.  They did hook up tubes for me.  And they were able to demo all the other Klipsh Heritage speakers for me.  They all sounded great.  Aaron (I think I have his name right) was extremely helpful at Safe and Sound.  He really understands sales and customer service.   I met with the owner of a Heritage dealer outside of Boston.  Great, warm, enthusiastic and helpful individual.   He gave me a tour of his place and played some K-horns on solid state amps.  I think they needed tube amps to warm up the sound that I perceived to be a bit harsh on the top end.  They had sounded better to me with tube amps at Safe and Sound.   Good base but not as low as the Jubilees.   I'm really looking for true full range solution.  He took me to his home and played the Jubilees which he has in his listening room.   He had them with solid state on the bottom and tubes on the top.   In this particular room with this set up the sound stage didn't open up as wide as I had hoped.   Might've benefited with tubes on the bottom as wekk as the top or maybe the set up in the room which was filled with equipment might have colored my listening experience.    I went to the Capital Audio Fest.  140 rooms of equipment.   Almost boggling.   My wife got some nice dinners out of the trip and we went to a great Jazz Club in Georgetown: Mr. Henrys.    We spent 8 hours at the show on Friday and 4 hours on Saturday.   Lots of great innovative things going on in the audio industry.  Heard many speakers.  In the end I went with horned speakers (which I expected) with tubes.   Thanks all !

Never tried skipping preamp. will give it a shot. thanks

8 ohm, never tried 4 ohm, will give it a try

An Exorcist. 

Would be more believable if they could only be seen with a camera outfitted with lenses designed for infrared or ultraviolet wavelengths. 

I don't believe that, Mark. You won't be able to upgrade every LaScala to AL6 level. At least in my old LS the doghouse is completely glued and to upgrade to the AL6 not only the squaker and tweeter have to be replaced but also the woofer with a completely different 12 inch woofer and the slot for the compression is also completely different. If I have to replace the whole woofer alignement, squaker, tweeter and xover, plus parts of the dog house, plus purchasing a new active DSP, then there's not much left of an AL5. I would leave an AL5 and if you want you can buy an AL6 directly. Unless Klipsch is very charitable and sells the upgrade for a mildly symbolic price.

Your K402 is still pointing down a bit🙂or again after you tried it with straight alignment. I can't give a financial-strategic answer to the AL5 question. Only an emotional answer. I would keep the AL5 if I were you, at least until everything has settled down and the new AL6 has been released. Why? Because there might be more people like me. Personally, I would like to have a fully analog speaker in a fully analog chain (except for digital sources besides vinyl).   From my point of view, the AL6 is not an evolutionary development but a completely different animal. Certainly the AL6 will do a lot of things much better than the AL5. But does it still touch my heart? I loved your AL5 from the very first note, its tone, the color of its middle. I found it a bit weak on bass and lacking in spaciousness, but I imagined how it would have sounded in my room with my amps. You have very good amps, but I have a different philosophy when it comes to amps (more power etc). I would still keep your AL5, at least for a while, unless the money is very urgent. But I'm very subjective, I love my 51 year old Khorns, with all their strengths and weaknesses. A description as a comparison between Khorn, Jubilee (from memory) and 1977 LaScala will follow soon as well.

Really, you don't need an AL-5 to upgrade to an AL-6.  You can do this with any Lascala.  You may need to do some routing for the tweeter.  That ought to tell you what an AL-5 will be worth soon.
