Someone private messaged me about my experience so far with the Luminas. I cut pasted the body of my response for the whole group:
I really should post more on the site about my Luminas.
I am still trying to find something that they don't do well. I am sure there is a weakness, but other than their weight (they are VERY heavy) and that they are awkward to carry/move due to so much of the weight occurs in the baffle, I can't really think of a negative.
I have not tried a really low watt amp with them, but I often use my Pass Labs XA-25 (which is the tubiest sounding solid state amp I have ever owned) is only 25 watts into 8 ohms. I think the Lumina sounds better with more watts. The other amp I am using is the Esoteric A-100 which is a 45 watt amp. The speakers are more dynamic with the Esoteric, as they should. I have some nCores I should hook up just to see how they sound.
Transparency. You will hear everything you change upstream. I have had and continue to have issues with my front end. That is part of the reason I have not posted more. That and the fact that I haven't listened nearly as much as I would like to. They do not have as high of resolution as my Martin Logan Summit Xs did, but they are transparent and there is a "meat-on-the-bones" quality, especially with the Esoteric, that really leaves the Martin Logan sounding a little too polite.
Soundstage/Imaging. They do image very well, but I feel I haven't got the best out of them yet. I have heard Clayton's other speakers, in bigger rooms than mine, where the imaging was simply the best I have heard by a long shot. I am not there yet.
Bass. I need to measure my frequency response in room. The bass is amazing, plentiful and adjustable. The adjustable is probably where i need to work. The bass on these babies is absolutely to die for! And the bass from this design is simply different than that of a box speaker. Not just different, superior. Canon shots, sound and FEEL like canon shots.
Midrange. They don't offer the same purity as my Fujitsu Eclipse TD712z single driver speakers do, but the coaxial driver that Clayton uses does come very, very close. And the dynamics that the Luminas possess completely dwarf the Eclipse.
Highs. Let's be honest. I am a 60 yr old male. I don't hear anything above 8khz. So, that being said these speakers perform extremely well delivering high frequencies. There is a lot of air.
These speakers are dynamic, honest, deliver ungodly bass and are room-friendly. I have owned, Salk, Zu Audio, Emerald Physics (many models), ATC active (amazing in their own right), Martin Logan Summit X and Fujistu Eclipse, and others over the last 12 years. These are better than all the aforementioned speakers and in most cases by a considerable margin. I, for the first time in the last 12 years, am not looking for replacements! My wife is very happy and she LOVES the look of the Luminas!
Please call me or write with any questions or concerns. I don't know if you have dealt with Clayton, but he is truly great to deal with.
