Network Acoustics - Tempus network switch

[kennyb123]

Both are great sounding supplies with the Tempus. And if I didn't know about the other I would be happy either way. But I would say in this limited test I preferred the NA PS on the Tempus

Thanks for sharing your observations.

With the NA power supply there was definitely more detail retrieval and better separation of instruments/voices

Great to hear! And you will see with a better power cord the Tempus will benefit even more. Happy listening :-D

Did a quick 1 song comparison of the NA power supply & the Uptone JS-4 powering the Tempus (note: JS-4 had been powered down for a week and this swap was cold)

Gosh Frank, just one song and from cold? Gee, your JS-4 deserves a bit more than that.

Also, can you remind us what duties you took the JS-4 away from for the test? (Though the Tempus is a very light load, so I'm sure you could leave the JS-4 in 2.1A/2.1A Dual-Mode and power something else as well with the other output rail.)

This certainly warrants more testing

Thanks! Will look forward to that.

Hi Alex - Sorry. Agree that it was a very limited test but I did want to report what I heard. But will certainly follow up

In that test the JS-4 was only powering the Tempus at 12V on one rail. The Tempus has replaced my AD Clock/EtherRegen so the JS-4 is unused at present

I have been living with my new Tempus switch for a few weeks now and I can tell you one thing. It's not coming out of my system

Comparing my 2 different delivery streams:

1 Unifi Dream Machine Router>Ghent JSSG360 Cat 6>Sonore OM Deluxe/Farad Super 3>Cisco AOC SFP>ER/AD Project ClayX GIESEMANN/Uptone JS-4>Sablon 2020 LAN>Meitner MA3i
2 Unifi Dream Machine Router>Blue Jeans Cat6>Tempus>Sablon 2020 LAN>Meitner MA3i

Cold out of the box I was preferring the Tempus. But it was close. Only got better as it ran in. At 100 hours it was an easy decision. Hard to explain but it sounds more natural. What I really notice is it seems to go deeper into recordings. Soundstage is also a bit wider but the bigger emphasis is deeper/higher. At 300 hours it really seems to bloom. The larger soundstage appears to leave more room for instrument separation. Overall presentation is definitely smoother. I like to listen loud and do not like any harshness. None here. There is a naturalness to the presentation. A more liquid quality to voices and other instruments. And more realistic plucking of guitars. You just want to keep listening.

Going back to #1 I could notice it was a bit more strident/harsh (a bit). But noticeable. Not as natural. More top end. Not the same cohesion

Adding in the overall simplification of my system and it is a no brainer.

I did test out a Finisar FTLF1318P3BTL FMC to the Tempus and while it sounded very good, I still liked the copper feed better. Just more analog like.


I do have to test my Uptone JS-4 with the Tempus. It is a great sounding LPS. Even though NA strongly believes in their SMPS approach it will be an interesting test.

An now I just need that QSA Discovery Lan cable to arrive for the last mile to the Tempus........

Impressed enough with the NA equipment to be seriously considering the Muon Pro.

Just curious if you tried both of the switches in the same chain? Personally, I also like simplification too, but such experiments can be informative even if not successful. You know, in your copious free time.

Hi PYP -

I had already done that in essence in previous testing. My Optical chain through the ER easily bested copper from my router to the ER. So the fairest comparison is my optical ER chain vs the copper Tempus

I may be misunderstanding you. I was thinking: router > ER > Tempus > Meitner MA3i.

Some folks have found an advantage to using more than one switch. Could be an advantage is the switches eliminate different kinds of noise. Not sure if that is the case.

Hi,

I think it depends on the individual network setup at home and there is no 1 clear answer for all.

I don’t have the ether regen nor the tempest but I do have the silent angel Bonn nx switch and fiber box 2 extreme (similar to ER).

When I started out on my streaming journey, my network is router -> fiber box 2 extreme -> silent angel Bonn nx switch -> streamer, i was using the stock smps for my routers, commercial grade lan cables. I would imagine that my network back then has significant noise from the smps powering the router and also the high cpu usage.

Back then the fiber box 2 extreme was helpful to reduce the noise floor by a significant margin and resulted in a darker background and more clear sound.

However 2 years down the road, I upgraded all routers to be powered by hifigrade LPS, swapped all my network cables for hifi grade one and also optimise the network setup.

The fiber box 2 extreme was no longer needed since there is drastically lower noise across my network and including it in the chain only reduces dynamics of my system.

Hi PYP - Agree but I really didn't want the ER in the chain with it's 100mbps limitation. The Tempus is a 1GB switch and Network Acoustics insists the higher throughput is advantageous. Could be part of what I am hearing. Also Roon runs much better/more responsive with the Tempus

Maybe stacking multiple Tempus switches. it's only money

hadn't thought about the bandwidth since my switch only feeds the streamer, therefore audio only. Of course, experimentation is the only way to know and you have done that.

Someone has to be the first one to stack the Tempus! We know it has to happen because, well, audiophiles.

Of course, adding a Muon Pro would be a more cost-effective experiment. But for a switch-obsessive audiophile (not saying that is you), that will only delay the inevitable -- double Tempus. I assume the designers will shake their heads, shrug their shoulders and say: Ah, audiophiles are a different breed.

 

[f.demello]

I'm was more inclined to go the Muon Pro route (vs stacking) although the QSA Lanedri cables are throwing a monkey wrench into those plans

As I understand it, the Muon Pro will still allow the use of one’s preferred Ethernet cables both in and out. It would be fascinating to hear how well it performs with both in and out cables being Discovery Veridian. NA’s own streaming cable is said to be excellent so it’ll be interesting to hear how they compare.

I guess the key word, and thus very subjective is 'high quality' digital audio data being delivered. Because no system/environment/LAN is noise free. Quality components (ie. switches), filters, cables, etc, are always a matter of noise reduction. The degree of succession at that task determines a device's (or cable's) value. And the Tempus removed/filtered more noise from my system than any other component to date. As I've said before, not many things improve everything in a complex system (audio streamer, OLED, video streamers, etc). The arrogance was thinking my system couldn't sound much better before springing for the Tempus. Was it what I would consider high quality? Sure but I would also never go back after hearing how much better it sounds with the Tempus inserted.

A very interesting statement: a digital data packet with integrated error correction causes analog noise. This can only happen if your DAC does not have good galvanic isolation. I would rather invest in a DAC that can do this better than in expensive additional devices. Radio interference from Wi-Fi is really a problem; the higher the signal strength, the less interference there is. This can be easily optimized with the Netspot app.
My recommendation is the reclocking DAC from Mutec Astralius. The uncompromising galvanic isolation, together with the built-in reclocker mc3+, creates a very strong barrier against interference from the digital side.

I can't recall if I read it in this thread, but wasn't there a recommendation on the port to use for the output ethernet cable? The 1GB section offers better sound, right? But do you plug the ouutput cable in the port right next to the input cable or do you leave empty ports between them?

 

[luca.pelliccioli]

In my experience it’s better to keep in and out as far as you can one from the other.

 

[Republicoftexas69]

I do

I do this on my Edisoncreation Silent Switch.....

Thx for confirming!

I like my tempus and my muon pro, works wonders for me.

I got the Aurender N50 on way to me as I sold the Oladra recently and am beyond excited.

My tempus and muon pro will be used right before the N50.

They also have a no risk trial I believe. Great guys, two of em dudes.
