I would expect nothing less from anyone serious about their system. However, there are several factors that must be carefully considered. This has to be an audiophile grade generator with windings from copper cured for +500 hours in a bath of meticulously temperature controlled vintage crude oil at ridiculous pressure. Also, a precision generator must not be powered by any run of the mill diesel engine (engines with harmonic dampers are particularly ill suited for audio purposes, but that goes without saying I guess), actually any piston engine is likely to have too much torsional vibrations resulting in overtones in the output of the generator. Japanese audiophiles swear by Mazda rotary engines but recent listening tests with gas turbines from General Electric running at a speed tuned to an odd multiple of the crossover frequency of the speakers gave favorable results. It wasn't a blind test though, the leaves flying off the trees outside the window was a bit of a giveaway. Next is the choice of fuel, naturally there may be no additives that may affect the imaging or contaminate the high range the way ordinary cheap jet fuel would. Medical grade ethanol is preferred by many for it's neutral tone, while a 24 year single malt is popular for the noticably warmer glow it gives to the tube amps and you will also enjoy a slightly smoother sound from your vinyl records. Sadly, the whole idea of running your own generator falls over since there is no economically feasible method of supplying enough air of the quality required. Normal outside air varies wildly when it comes to temperature, humidity, pressure and oxygen isotope ratio, not to mention the sonically detrimental effects of certain pollen types. So far, listening tests has been constricted to 5 minute sessions, nobody has been able to provide more processed air of the necessary grade to run the gas turbine for longer periods than that. If you live in a rural area and has a less revealing system you may get away with using outside air during the month of october.
Maybe one shouldn't mock this stuff though, spending money (even absolutely obscene amounts as in this case) on a power cord does in some sad way make more sense than spending them on "audio grade" USB cables or hard drives. -- alfista ------------------------------------------------------------------------ alfista's Profile: http://forums.slimdevices.com/member.php?userid=32396 View this thread: http://forums.slimdevices.com/showthread.php?t=91896 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
