Default Hypex ucd 400hg vs 400hg hxr.

I´m planning to buy 2 400 modules from hypex and just want to ask if the hxr modules are worth the extra money over the HG modul ?

I have upgraded my UCD400 from HG to HXR, and would say yes!, HXR is worth it.

HG sounds very good by themselves, and I found it hard to believe HXR could do much good.

But the difference is quite clear. The high frequency is more clear and detailed, but the biggest difference is in microdynamics, and perspective.

On my system it made an amazing difference to the perspective, suddenly I could "look" into the music, and place musicians much more precisely than before. And small details of every instrument stand more clear.

So I would say, go for HXR.

This regulators supply the input operational amplifier and the gate driver? If the operational amplifier has NFB , the gate driver supply don't go too low and everything is decent decoupled with the cheaper regulator , then why is a difference in sound?Can this be explained technically?

sorry, nfb is negative feedback (i often see this abbreviation in this forum)

I see that the opamp is lm4562 which is very good .This opamp works with a power supply from +-2,5v to 17v and has a psrr of 120db. How can a better regulator make such difference in sound like some people wrote upper?
