Shielded vs. unshielded Ethernet and Grounding

[Ralf11]

curious about the forthcoming etherREGEN...

 

is it intended as a high priced ($3,000 level) sort of item?  or much lower?

 

is it going to be specialized for ethernet only?

[Ralf11]

Thx - those are the NVE Spintronics devices?

Air Defense for Everybody!

comfort relieves you from the stress of listening for a tiny decrement in SQ (and all the bad neuro-chemicals that implies)

 

comfort relieves you from the risk of falling down deep when a cornice snaps off 

 

comfort is a safety margin

[Ralf11]

is the offer good if I play Placebio Domingo?

Yes, he did. All over the place. Look starting here and then throughout the thread: * * *

 

If it is not "high-impedance leakage current", what is it?

 

 

it is a leakage current thru a high-impedance - Mansr can propose a different term if he wants

 

jabbr gave an xlnt and concise description (which should be placed in the CA Archives)

 

my question is: how important is it likely to be - esp. given the recent ruminations from jabbr about noise levels...

 

OTOH, it is easy to get rid of (some of) these - so just do it

[Ralf11]

yes

[Ralf11]

Yup

 

- he may mean on the receiving side, but that is why I used the word "some" ?

[Ralf11]

Thevenin's theorem - for those listening in... no 'i'

 

** people could post the color coded model output from the $$$ software, or just point out how to avoid / deal with leakage currents

[Ralf11]

Some say the transformers on wired ethernet do not adequately reduce parasitic leakage currents, which carry noise to the DAC...

 

It is not too hard to use optical and solve that problem

 

... or use WiFi as per the above post

 

of course, it is always possible that the convertors on the DAC side inject noise into the DAC

 

or that noise arises inside the DAC or its chip

 

and then... there is Johnson Noise✋

[Ralf11]

what DAC do you use?  maybe it is impervious, while lesser ones are not...?

[Ralf11]

ok, designed to be impervious - I agree it never hurts to do a few simple things to reduce EM noise

 

do you know what GK does in his DAC?  does he use opto-isolators? and/or...
