$9000 speaker Orangutan or speaker + amplifier

The Orangutan is intended to be moderately high efficiency and an easy load for tube amplifiers. A transistor amplifier is not likely to show them off properly- I suspect that the design may not work properly with transistors. (for more on why, see http://www.atma-sphere.com/Resources/Paradigms_in_Amplifier_Design.php.)

Given what I have seen of them, to really make them sing you will want some power, of course a lot depends on your room!

Tube amp + Orangutan (very cool name for those speakers BTW) is likely a very good match, but I would still lean towards 30 w/ch Pass SS amp with 90+ db efficient Orangutans rather than any 30 w amp, tube or SS with 86 DB efficient speakers, Harbeth or otherwise, for best performance overall, given the choices, but personal preference in individual cases is probably the deciding factor in the end. None of the combos should sound bad, especially at low to moderate volumes. It all depends. THat's what keeps this stuff interesting. You often never know for sure until you try. Specs and technical designs only tell part of the whole story.

Atma,

I thought the Orangutans O/96 will go well with SET amps (8-10W), is that not the case ? That would be sad, if so I will not bother with the Devore. My prime interest in this speaker would be to get a chance to try out SET amps and see what the fuss is all about.

Mapman, If I go for the Harbeth I would have to spend the 5K difference in price (between Harbeth and Devore) on a tube amp 50W+

So approx it will be same cost. 10K + change.

12K = Devore Orangutan
6K (Harbeth) + 6K (Higher power tube amp 60W) = 12K

Still wondering which might be better.

Having never heard either speaker, and seeing both options as viable, I see bigger up side with larger and more efficient and costly Devores even off you r current 30 watt amp, so my guess (only a guess) is that is the better way. But no telling which any individual might prefer. If someone has heard both speakers and could chirp in, that would be helpful.

Are you able to audition either before committing to buy new? That would be a big bonus.

Otherwise, wait to buy either used when you can and do not overpay and then sell and try other later if still needed without taking much of a financial hit.

Otherwise, take your pick (along with new amp if needed), but be prepared to loose money if you buy new and end up still wanting to try the other and have to sell to finance. With Harbeth, if you sell you might decide to keep the new tube amp to use with Devores and sell old amp, in which case financial loss would be less selling just new less expensive Harbeths.

If you're buying the Devores new, why don't you take advantage of your dealer's expertise? Nobody here owns them, so everyone is basically talking out of their ass. Go to the dealer, try them with a set amp and try them in your home if you need to. Then you'll really know if everything works. When you pay full retail, you should take advantage of the dealer's services. That's a significant part of what you're paying for. I've owned the SHL5 and they are wonderful, so you won't be making a mistake with them either. It's just that if you're buying used, you don't get to hear them before buying. It's a crapshoot at best as to whether they'll work in your room.
