Article: UpTone Audio EtherREGEN Review and Comparison

Recommended Posts

Excellent review. My industry training also made me skeptical about audio unique benefits from an Ethernet switch but clearly something is going on that affects an audio USB

device with an active NIC. Based on your review, looks like I'll be buying yet another DC power supply to power the Etherregen 😉

Thanks David.

 

Have a look at Uptone's white paper, linked in the review. Food for thought.

GREAT review, Rajiv!!  As usual, you take more time and effort, and exceed all expectations!  Very illuminating with specific POVs that still allow us to ponder, but now with more and better info. Congrats to @JohnSwenson and Alex for creating a great new switch at an affordable price!

Very top notch review!  This is the type of review should be used as baseline for all reviews.

 

Well done, Rajiv!!

Looks admirably thorough but have you tried with cheap CAT6 UTP cables, you know the ones with plastic connectors so they don't create ground issues to start with?

Thanks for this extensive review and the different evaluations.
I still have a basic question.

Did you try once, playing form an internal drive in your music computer? I know in "theory" there is no difference for stylus in ram. But you need all the different stuff and different cables to feed a „one-box-solution“?
Thanks again for your impressive deep review.
Btw…nice music decision…

Great review, but perhaps one obvious point should be emphasized: the ER only addresses signal quality upsteam from the source connected to the DAC, so its effects are limited.

When you have a complex system like Rajiv's with multiple custom Paul Hynes DR SR 7's connected to your network devices, fiber isolation, multiple well designed switches clock synced by a top reference clock, JCAT Net Femto NIC powered by another Paul Hynes LPS, and so on - I can tell you what happens to those cheap CAT6 UTP cables with plastic connectors - you throw them in the garbage because they are the biggest enemy of your sound system. That's what happens :).

 

Amen!!!

Rajiv, a fine review, thorough would be an understatement!

 

One point to clarify, you placed the SQ of the EtherRegen and S100 as being very close.  Am I correct that this was with the EtherRegen using the REF10’s reference clock, and the S100 necessarily using its own clock?  I think I have this right, but I’m not completely sure.

This is a deep topic in its own right, and will take this thread off-topic! So, please post any followup on the thread I'll link below.

 

Yes, I have indeed tried internal drives, and it takes a lot of effort and optimization to mitigate for their presence in the music computer. Not saying it can't be done, but it's not as simple as just hooking up an NVMe SSD or SATA HDD.

 

The reason I went the NAS route is based on the simple idea that NO storage disk is quieter (from a noise perspective) than even the quietest one. And this was facilitated by the use of Euphony OS and Stylus. Once you can pre-buffer the music before playback, you've taken the storage device out of the picture.

 

I suggest you take a look at this thread: https://audiophilestyle.com/forums/topic/30376-a-novel-way-to-massively-improve-the-sq-of-computer-audio-streaming/ Check out the index in the first post, and do some searches. You will find people have discussed these tradeoffs extensively.

Yes, exactly right.
