klipsh scala speakers

I have had my La Scala speakers for 35 years and am still finding ways to make them even more enjoyable than stock. (which I liked) Over the years I have built stands to angle them, built crossovers, bought crossovers, tried many different speaker cables and just messed with placement. Mine are matched with Mac gear and every little change was evident in the listening experience. Some would not want to put that kind of effort into their system but I relished it and still try different cables just to see what the effects will be. This might be a consideration for your son. Hopefully he can find as much entertainment in the quest as I have had. All the other comments about low playing levels, details and volume are true in my experience. For 30 of those years I used no sub, now I have 3 svs sb4000s and would never ever ever go back. Subs are essential in my experience but not unique to La Scalas.

A few questions to the OP:
(1) how big is his room? Do you understand how large La Scalas are?
(2) do you really want to spend $12K on speakers for your kid (assuming new)? If so, congratulations on your deep pockets and generosity.
(3) if his primary desire is loudness (assume he is going to listen primarily to rock or club music), steer him toward Klipsch Heresy, JBL L100 or vintage Cerwin Vega speakers.

"way too much stuff" hit it right on the head! you absolutely need good components ahead of any klipsch speaker. i have owned my cornwall 2s since new and would never give them up, BUT YOU NEED good high quality equipment ahead of them. that goes for cables too. with cheap recievers and cd players your ears will bleed. 

Speaking as one who is no fan of Klipsch products, but who has sold them professionally, the latest Forte should be the ticket for your son...quite sensitive, and much fuller range and better balanced than La Scalas, and therefore more forgiving.  Driven by a Rogue Pharaoh tube/ class D hybrid integrated they should do their best.  Consider reminding him too of the long term damaging effect of overly loud playback on one's hearing.  It shows up decades later...believe it!

They look more impressive than they sound. Not to mention the size.
He might be a Tekton buyer.
