Objective proof the UpTone Regen ISO can improve a DAC's output(*)

It would be nice to know if LPS-1 is needed for proper ISO-R operation. A $325 ISO-R price tag is significantly different than the $655 bundle with LPS-1.

In the real world we call this "bait and switch."

Being a USB regenerator, ISO REGEN is intended to clean up the USB signal going from source to DAC.  From measurements perspective, the measurements should be focused on quantifying the USB signal quality differences at both ends of the device.

By that logic, the green pens for painting CD edges should be judged solely by their ability to paint the CD edges green. Since they clearly do paint CD edges green, this is all the proof we need that they work exactly as advertised.

Yet still -112 db below reference, inaudible.

What happened to the "everything matters" mantra?

Are you referring to the buzzing introduced by the Regen?

D.C. and low frequencies flow along the path of least resistance. High frequencies along the path of least impedance.

No, current flows along all paths in inverse proportion to their resistance (or impedance).

It's like faulting a french press maker for not explicitly telling a customer their coffee will taste like crap when the customer decides to use Folgers with the press.

I'd say it's more like faulting someone for selling an expensive water filter that makes clean water taste worse and does nothing to filthy water while a cheap filter from Walmart renders the filthy water quite drinkable.

It does improve the output of the Modi 2 where nothing else has done so. The improvement is no insignificant.

What else has been tried? Perhaps the proper solution with the Modi 2 is to buy a different DAC. You can get a respectable DAC for the price of the Regen alone.

All of these post and everything happening has proved four of my fundamental beliefs:

1. In Audio everything matters
2. We don't know/understand everything
3. We can't measure everything
4. We can't hear everything

Bit of a contradiction between 1 and 4, I'd say.

Utter nonsense.

 

That was his JOB> And he was specifically directed to this other things which failed to do DIRECTLY by Bill Gates..with BIllions

at his disposal.

 

99.9999% of the others did not have a MS Warchest.

 

No character assassination.  That is Amir's job.

 

All in the public record.

What Amir did or didn't achieve at Microsoft is utterly beside the point. He set up a measurement and published both the details of the setup and the results. The relevance of this test has nothing whatsoever to do with his success at competing with Apple. Lots of good engineers are terrible businessmen, and vice versa. I don't know Amir and can't judge his skills in either area, but the test results he presented are in no way dependent on his personal success at anything. They showed a detrimental effect of the Regen device in a specific configuration. If someone takes issue with this, the proper response would be to replicate the setup and demonstrate a different outcome. Lambasting him for failing to be Jesus is pretty much the definition of character assassination. Even Alex has conceded that Amir's results are probably accurate. The matter is settled. Move on.

He could lose a lot of money by posting measurements of the products he sells and already has readily available.

And Alex couldn't?
