Actually a little presumptuous on your part sort of implying he's a kool-aid drinker. He was the first person to link one of the crocodile hunter objectivist videos on the forum asking for discussion. He replaced it with another because the guy comes off like a jack ass from an infomercial or petting zoo. I'm sure you're no stranger to certain people in audio espousing universal statements of fact from data of questionable value or correlation.

Ah, I must have misunderstood.

That'll cost me a constructive comment: isn't there a trade-off between the rise time of a square(ish) wave and higher harmonics which then manifest as added noise? Furthermore, if the switching threshold is reached with the same periodicity, then what effect does it have on jitter?

It seems you either need a LOT of different 'cleaners' (or use the newly released iFi which does it all ?) for optimal USB results.

This is why I take the subjectivists' advice and don't worry about it 'cause I can't hear it

As far as I'm concerned if I buy a high end digital audio product which turns out to be plagued by noise or connection issues, then I consider it defective and fit for a refund.

Actually, a lot of objectivists I know say stuff like, "fine, you've shown me numbers: now show me tht they translate into anything anyone can actually hear."

I don't care what it cost, if I hear noise from an audio component I throw it away. I do not have a high-end system: silence, played at full volume, gives me... silence.

(exception: turntables and vinyl)

(Oh, and my pre-amp, which is high-end but somewhat antique, has a sometimes noisy pot. Allowances have to be made for age. Even I crackle a bit.)

Yet another (positive) review of the jitterbug and the regen.

as soon as i saw synergistic research mentioned any and all credibility of these article was gone for me

anecdotal for now, friend plugged a jitterbug (also an effective small mouth bass lure) into an unused usb port on his mini , "it sounded horrible", he plugged it into a usb port > his power leg less usb cable> to dac and it sounded wonderful.  Tip to him, try it without the Jitterbug and then let me know.
