Looking for advice on these speakers

Thank you, gentlemen, for all your input. I have to say, I'm a little bit surprised reading opinions about Daedalus speakers as they are appreciatively more efficient than Coincident speakers. Seems they should be a better match for low-power amps than either Coincident or the Silverback Reference. Even if the impedance is hovering between 7 and 8 Ohms above 100 Hz (according to Lou), at 96-97 dB and a flat curve they should be top contenders for SET amps, based on their specs at least. .

Thank you all very much for an excellent advice; it's greatly appreciated.

To answer the questions posed, right now I'm leaning toward a 300B SET amp, and actually considering the very amp Charles has, i.e., the Frankenstein from Coincident. I've also been looking at Border Patrol amps, but I think they may be out of my price range when all is factored in. I do not have any experience with the 845 tube (or any other tubes Charles listed, as a matter of fact). I do have some concern about a SET amp not possessing enough steam to offer satisfactory dynamics and punch for rock, which is about 50% of my listening. From what I'm reading, a Coincident speaker or the Orangutan may be a better pairing than the Athena or the Argos. I've read Charles' posts in other threads before posting this one, and it sounds like one can hardly go wrong with a pair of the Franks and a Coincident speaker, especially the SV.

The room size is roughly 20'X12.5'x9', but the long end opens up into an additional 10' by 12.5 kitchen area separated by a large column and a mini bar counter jutting out from the side wall. So it's a decent size room, I'd think.

I spoke with Lou a while ago and he was willing to put me in touch with Daedalus owners in my area, so I may reach out to him again, and possibly Israel, to see if an audition could possibly be arranged.

My post may be better suited for the amplifier forum, but since it is related to this discussion, I hope you'll indulge me.

My 180-watt tube monoblocks have a switch for ultralinear and triode operation. When I first got them a few years ago, I settled for the ultralinear mode and never thought to re-audition the decision, I guess since the mode was arguably the best compromise between low distortion and most power. This thread made me go back and revisit my choice and oh my. Perhaps there was something in the air today and it will disappear, but it was a revelation. The sound may have lost a fraction of the punch with rock music, but I just can't get over the overall improvement. Hard to describe it, but it's as if the sharp edges have been smoothed out, and a new quality to the sound emerged and made familiar recordings sound so revived and fresh they became literally intoxicating. In an A-B comparison, I could tell some difference, without a clear preference, leaning toward the triode mode, but not to the degree that the subsequent listening confirmed.

My amplifiers are obviously not SETs, but I'm curious to understand why switching to the triode operation made such a positive difference. Am I getting a taste of a true SET amplification with my 180-watt amps operating in the triode mode?
