Thanks for this link, never noticed it on their website!

If my exceptionally complex calculations are true, then this thing would output ~1.4W @ 62Ohm (K701) and that's a lot

That is what I was trying to say and it really has very little to do with time difference. The rest I absolutely agree with you..

[size=x-small]I hear you loud and clear. For some reason some people seem to post strange and/or totally impatient questions to this thread that should be addressed directly with A-GD if they really do have a legitimate question at all. I'm continually amazed at how responsive A-GD is. I honestly think Kingwa should sleep more, but I respect his work ethic 110%++++. He's my type of professional, and I'm putting my money where my mouth is....

I think scenarios like Doping Panda's and others brought to the thread tonight are perfect reasons why this thread exists, and I'm very glad if any of my responses helped them out at all. These guys are just clearly music lovers wanting to enjoy their music...

Glad you found it useful, that link has been there for quite a while, you need to click on the specifications (above the dimensions and price in the Compass page), just like most of Audio GD's other gears, they don't write the technical specs on the product page, but provide a link to it.

SS,
Here's what you want to use. The itter specs are non existant. I use one to feed my Compass and a set of Digital studio Monitors. It is VERY Nice.

Emmm ... a lil bit of off topic, anyone one tried to place some Vibrapod isolator - The Vibrapod Company under their Compass? Quite alot of users from worldwide reporting audible improvement using them underneath CDP, DAC, AMP, Vinyl ...

Most important is their price is kinda cheap, USD6 per isolator

How susceptible do you think electrons are to Vibration?

Shhh! If you respond the tweak supporters will get angry. And when they come around, so do the skeptics! Pretty soon, we'll have another one of those ugly debate threads.

...Let's sit back and enjoy the music.

Emmm ... doesnt has a clue ... but I believe there must be some "effect" there ... as Kingwa mentioned before, you must do the practical part instead of blindly following the theory, best part is some of the Vibraport dealers are offering 30 days Money Back Guarantee

I guess it's no harm to try with this scheme

No harm at all. It's your money after all

Electrons are subatomic particles and they can get very confused with vibration. Result: particles that both don't know where they are and don't know where they're going. Jeez, don't you folks read your Heisenberg.

I have yet to receive a plausible answer to that question from anyone, whether audiophile or high end equipment manufacturer.


It's odd quoting myself, but I just saw a very interesting article on the topic of jitter by Steve Nugent of Empirical Audio in the May/June 2009 issue of Positive Feedback. It's the most thoughtful and intelligent discussion of the topic that I have seen, stripping away the usual audiophile bombast. While Nugent certainly advocates for reducing jitter as much as possible, he cites subjective listening tests in which, "the majority could not hear any difference between the tracks, even though the jitter ranged from 0 ns to 1000 ns." [Jitter is usually measured in "ps" or picoseconds, so 1000 nanoseconds would be an immense amount of jitter.] Nugent's position is that the tests show, "just how unresolving most audiophile systems are," and that it would take a trained ear to hear the effects of jitter. He even notes that in some cases, jitter could have a modest beneficial effect on sound, similar to that of adding dither.
