Pops--
FWIW, I've been running the 14 since 1997 with matched Mullard 6GK5s. Audible improvement over GEs, particularly on voice, piano and strings. Top to bottom, the 14 has more of what you hear with GE or other tubes that I've tried. I also had a 17 in the system for an extended audition and possible buy (less money than the 16), but OVERALL, the 17 didn't equal the Mullard-tubed 14LS; I found it less appealing through the upper mids and treble region--not as much "there" there. System: Avalon Arcus, Classe Ten (modded), Accuphase CD player and tuner, Luminous Audio Technology Synchestra Signature ICs, Symo Speaker cable, Shunyata Viper PCs and Hydra.
