36v has more detail, clarity, and holographic imaging by about 25-30%. I often said here on AC about the Ncores, give me a lower PSU or battery, the Nores would no doubt sound a lot better.
I have run these with the same results on Zellaton Emotions, Gallo CL-1's, Audio Nirvana 8" full range, and Spatual M-3's. Rex has run his on Omega Super 3HO Monitors, Decware DNA Horns, and Audio Clarinet 1+1's with the same results.
It is amazing how Tommy O amps sounds so good with so many different speakers. And I was one of Tommy's biggest skeptics here on AC.
