Tony Gee/Humble HiFi seems to be the only widely read reviewer of exotic caps who also tests caps for benefits accruing from .01uf bypass. In most cases he finds bypassing preferable(particular in crossover), and for this purpose he likes cheap Vishay MKP caps. I have not compared these Vishays to Russian FT-1, but I doubt that the Vishays can equal NOS Russian teflon in such applications. However, one cannot use bypass caps to make a silk purse out of a sow's ear. In my crossover, Claritycap MR without bypass easily surpassed stock cryoed Hovland with teflon bypass.
Reb, .1uf K-71 styrenes bypassed with .01uf FT-1 teflon sound damn good in PS around DAC and analog section of my CDP. However I have not compared this arrangement to much else.
