    Walt Jung was one of the first people to claim that capacitors affected sound quality and was one of the first to undertake some research (as far as I'm aware).

    No Oliver. Didn't touch a nerve. I just read the thread last night and thought a bit of a strange way to conclude. Personally, doesn't bother me in the least.

    Sorry if my humour was perceived as cynicism. It's what I love about forums: the way comments can be perceived totally different to that intended.

    Don't need to pull stuff off Google, Oliver. It's just what I have in my head. Go and read The Audio Amateur Jez mentioned, if it's on-line.

    There definitely context missing in the written form! I will definitely do some reading on the subject.

    I do see it's a bit of an odd way to conclude the findings and there definitely is a lack of technical info. I dont have that much technical nous but my ears are good so everything is done and judged by ear.

    I think I should have thought about how it would end before starting it. Maybe a "audible differences in capacitors" thread would have been a better thread.

    No harm no foul.

    What's happened to the superdooper Firebottle phono stage capacitor evaluation, gone up in smoke?

    Not at all Jimbo!. Its still on-going. Trouble we've had is that the Op amps aren't performing in the way one would expect so basically a redesigning of the circuit is taking place.

    As far as Capacitors go, Alan is looking to try and create a circuit that removes them altogether,

    The lack of news is my fault! Ive been on holiday and preoccupied at work.
