I own both amps, the BHSE and WES that is. I sincerely doubt this is the answer you are looking for, but at times I prefer the BHSE and at other times I prefer the WES. That is with the SR-009. With the -007 Mk 1, I generally prefer the BHSE. (Note: sources are a Bryston BDP-1, various Macs and/or CD players, DACs are a Bryston BDA-1, Weiss DAC202 or Wavelength Proton -- I often alternate between amps in the exact same setup). The sound of both amps does change quite a bit with tube rolling, with the WES having the more dramatic changes of the two (which is a blessing or a curse, depending on your perspective). They are both highly sensitive as to source, if not to every link in the chain -- they have practically ruined non-critical listening for me, since most albums seem to be recorded poorly. I've also been forced to tweak my setup (interconnects, sources, etc.) more than I would like. I range between irrational love of each amp to feeling underwhelmed, though that may have more to do with day-to-day/seasonal changes in my brain/ears and/or the dirth of audiophile recordings of interest to me than with the amps themselves. Friends and family (read, non-audiophiles) generally have no preference between the two. Resale is undoubtedly better on the BHSE, but at the expense of a long wait. I don't think you can go wrong with either amp. I haven't heard the Liquid Lightning.
