Hello @lalitk , I have now spent some time comparing my current JCAT M12 Gold switch with the GTT Switch X and its companion Wifi X.

The Switch X sounds better.  Soundstage is wider and deeper.  Instruments are more separated, background blacker.  Bass is more present.  It is easy for me to hear.  

I know I am hijacking the Tempus discussion.  I am sure the Tempus is amazing.  I love Network Acoustic products and use two Muon Pro systems.  But I think it is that the Switch X is also a modem, and creates a clean network for music only.  Plus a switch.  I think we will see many more of these clean network modems from other manufacturers.

I can handle this upgrade because it is compact, goes in my office, and replaces something rather than just adding another device. (yes it adds the wifi but that is just a fact of having an isolated network for music only).

I read the Tempus review @markush posted:

There is also a review at: https://the-ear.net/review-hardware/tempus-is-everything/ which sounds really very promising. So I decided to get one 😃

I could say almost the exact same things as Mr. Kennedy (he is very elegant) about the Switch X as he did about the Tempus.  The big difference here is that he is comparing the Tempus to an English Electric (same as teh b with iFi power  vs my comparing the Switch X to the much better  (as @lalitk knows) JCAT M12 Gold Telegartner switch. with Sean Jacobs AR6 power supply.

The Switch X with Wifi X with included DeJitterit Power Supplies looks like the real deal and a value at GTT's price for this kind of upgrade.

Also to note, I tried adding the M12 back in just before my Muon filter (downstream of the Switch X) .It seemed to make no discernible difference.  I wonder if there is a benefit to putting it between my Verizon modem and the Switch X?

Finally, I think most folks miss the point of Switch X also being a modem.

?Smitch X  ? Clean Switch X?  SwitchMode X? ModeSwitch X ?  Modem x Switch?

I cant even spell switch correctly anymore :)

@lalitk I' also thinking of getting the Opt Bridge 1000M Optical Isolator.   I wonder it if it requires the special ethernet cabling?  Marcin (of JCAT) will know.  Have a n open rail /cord from the Cat PSU.

Hi @lalitk @wsrrsw @soix I posted my thoughts on the Tempus Switch on the What's Best Network Acoustics - Tempus thread.  In case you are interested!

@fastfreight 

Thank you for posting your impression. The tech keeps on evolving, maybe someday I get the opportunity to compare Tempus in my system. 

@fastfreight I did read; you bet. Thanks. (Page three for you cut to the chase types) I will not steal your thunder/thoughts and post a spoiler here.

Chaining the JCat and Tempus goes against the shibboleth of less is more but I don't doubt you either. 

I was impressed with the very cordial and cicil tone on What's Best.
