Andrew,
It's difficult for me to answer that type of question without hearing the Orpheus on MY system compared to my Temper W. I wouldn't call Larry's system all that warm to begin with. It's a very detailed system that excels with classical music, which IMO is no simple task. Also, we're talking about horns here.
That said, I didn't find the Orpheus to be much different than the Temper in the warmth category. It's slightly more detailed, digs a bit deeper and seem to have a blacker background with a bit more transparency. I really don't think it's a night and day difference as described above. It seems to do everything the Temper did, just a little better. There's also the issue regarding Larry's "V" which certainly sounded better six months ago than it did when he traded it in.
From what I've heard so far, I believe the Temper and the Orpheus are very similiar. Is the Orpeus worth the difference in price? It certainly was for Larry. I'm not so sure I'd feel the same way on my system playing old jazz LPs 90% of the time.
