Ok, thanks.
Do you know what the 'crystal technology' is ?.

Dan.

Pure BS :smash:

"The Bybee AC Module creates a holographic, 3D sound stage imaging that is unattainable anywhere else in the stereo industry. It works best in power conditioners and amplifiers, however it can be effective in any equipment where space permits. The product is designed to be internally installed, and inserted after the IEC (incoming AC) on both positive and negative legs, and on the ground wire"

3D sound via the inputs of the power transformer huh? Please pull the other leg while you are at it. :rolleyes:
 
Scott,
Frank is downright delusional I must say. So if I put a gun next to his ear and fire it his ear can protect itself because the sound is not distorted! Crazy I say. Don't they have people in White Coats down under? Someone needs some electroshock therapy, preferably with Vacuum tubes and large capacitors as the power supply!
 
Dangerous BS
Deary me ... if one keeps one's eyes open, then you come across this comment many times, by people who are in the game of dealing with higher level sound. Musicians in the middle of decent sized orchestras, big brass bands, bagpipe groups are constantly being subjected to intense dB levels, over extended periods, they can't run and hide in a quiet corner when they feel like it, when they've had enough - do they have some magic powers we don't know about ...?
 
Been to the symphony lately , there is no intense dB , crescendo's very rarely exceed 110db for more than 5-10 seconds, nominally it's 84-89 db ( yeah i measured ) horns are the worst if you are in their path.

Many practice session son, part of the process if you serious about this, there is no 132db symphony, unless you listening to the 1812 in front of the cannon ..


:drink:

Interesting you should say that - that's exactly what did happen to me, at the end of high school ... an idiot fellow student let off a starter pistol right next to my ear when I was unaware - my hearing had absolutely no warning it was going to happen, wasn't able to protect me in time. That ear played up badly for months afterwards, running off to the doctor and specialists, very slowly healed - but was always the weak ear for loud sound from then on ...

Fascinating how people always have to throw in a grossly exaggerated example, when trying to make a point ...

All depends which way it is pointed. ;)

What he really needs is a decent Mid-Fi system to tweek…….Then we will get no respite whatsoever! :rolleyes:

Yet again, people can't read words - I said 132dB peak, not average - I mention a magic number, and people think I want to listen to a constant barrage at that intensity - get a grip, mate!

If I wander up a live drummer, and he whacks a hard rim shot just as I pass by, there you go, a 132dB peak - everybody's ears on this forum just exploded at the thought of it ... :D.
 
Hmmmmmmmm well according to this website Bybee Curl Holographic Power Source

"In order to introduce Bybee’s new AC module, generate buzz, and attract the attention of audio equipment manufacturers, Jack has created an extremely limited run of power conditioners with these AC modules inside. There are only 10, and no plans to make any more than this."

So at $5400 a pop I guess that will pay off his new car :confused:

"It really has to be heard to be believed"

I think I'm going to be ill.:whacko:

BTW, there are most assuredly 132dB peaks in an orchestra setting, a serious study found that such peak intensities from some normal instruments, at reasonable distances occurred - it's a real "issue" ...

AD in the digital path I see ;). I've been playing with the new AD1955 reference design in differential mode, fairly impressive. Measurements of course, it passes a multitone better than an old Crystal design. Yes I'm biased, but don't hide it. :D

I should give that a try. Trying to complete an ESS based DAC but getting product is a pain. Hopefully this next week it will be running . . .
