I have one deployed in my system and it I cannot tell a difference. I like that it supports the PC going into my X200 so it is a expensive support. I found the Akiko Tuning sticks to be effective attaching them to the power cables feeding my power distributors and conditioner. Can buy these things on Aliexpress for a lot less!

Oh exciting to hear - thank you for the pointer!
@Network Acoustics Based on the options provided at https://www.synergisticresearch.com/isolation/accessories/pink-fuse/ what version would be most suitable for the Tempus?
For some reason out of ALL the audio tweaks, fuses were always something I refused to look at or be open minded about. Unsure why but it is what it is.
Well for sure this is not an area very obvious for many, but offers a nice potential. There is a video and audio files to download at the end of page https://www.synergisticresearch.com/fuses/master-fuse/ for comparison (and this is just between these two). Many dealers lend you some or you have 30 day money back anyway too.
NA, If possible, please research the size of DC barrel/plug for Verizon FIOS G3100 router. It’s slightly off from the standard sizes. Very frustrating! Fios is a very robust Fiber system & I’m sure the G3100 could benefit from a dedicated LPS. Perhaps someone has located the proper size DC plug without crimping barrel as someone else suggested?Hi Luca, The tempus PSU is not compatible with most Routers. This will be a Router specific power supply based around the same technology we developed for the tempus PSU, but tailored to the specific needs of a Router. It will be rated 12v/3a. We will share more information very soon.NA
I've ordered the Tempus. I'm lost about how to install it when the Tempus and Power supply combined width is 20". My equipment shelves are 18” wide. And the umbilical power supply cable is too short to allow to separate to a higher or side by shelf. Usually, power supplies shouldn't be stacked on top of what their powering. Best sound generally best sound is realized by setting apart. Anyone tired comparing stacked vs side by side placement?
How long is the DC wire? I agree with you, I’d prefer having the units well separated. As soon as you find a way to place it in your rack, I’d be very curious to know your thoughts about it compared to the PhoenixNET. TIA

Initially, I looked at photo on the order page and the umbilical looked really short, then I re-reviewed the specs and found it's a 1m long, so I will be able to separate them onto individual shelves.
Rob one of the co owners told me before it is more than OK to stack em. Just fyi.
Good to know, thank you. I ordered the Tempus Friday. The NA web site showed it had a month back order, so was surprised to see Fed Ex show up at my door this morning with my Tempus.
Yes service
Yes service / support is always great from NA. Very much looking forward to your listening feedback.
Hi all, this thread got me to join here, thank you! I'm tempted by the April Synergistics Research Switch special, the reviews are great, but I've seen some comments in forums that it's not the best. For anyone that has compared the SR to other top switches, especially Tempus or Dejitter It SwitchX, would you please provide a little more info on what was different (EQ, dynamics, clarity, imaging, etc), and tell us which power cable and fuse was in use. I suspect that a Master fuse would be best for switches for the same reason that many are now thinking that SWPS are better, better transients. And tell us how long it burned in and which AC cables you used with the other switches.
--I almost forgot to ask @fast.freight since I think he's had both the Tempus and SwitchX. I'm also interested in hearing more detail about the sound differences between those switches.
I think I'd prefer the Tempus (newer design focused on timing, SFPs, purpose built HW, and hybrid PS), but have to be sure it doesn't make the sound too lean. The addition of an SR Active Ground Block SX w/ Euphoria SX AC cable has helped me get the bass back in my all digital, all SS system (details on Agon under user Nagel). I'll post about that on agon as soon as I get the Puritan Ground Master connected in parallel to restore the treble.
I think Dejitter It and SR are proposing a similar topology: use a router (SwitchX is not a modem!, SwitchX and SR Router use Router OS) to block unneeded broadcast traffic from your audio devices. SR goes a step further saying that removing that traffic from the switch fabric, closest to your devices, also helps. Did anyone compare the SwitchX as just a switch first, without the clean side/dirty side config? I'm trying to separate out that effect from the audio quality of the switch itself.
I'm eagerly awaiting more Tempus reviews since I have to decide on SR by middle of next week. The best system might be a Tempus fed from an SR Router or SwitchX.

I cannot address all your questions, but I had my new Tempus burning for a day. I owned SR with a Purple fuse and still have my PhoenixNet. It takes me a while to make the listening/ mental adjustment to a new piece injected into my system, so I don't have a clear idea of the sonic character between the Innuos and the Tempus just yet. My first impressions are good.
The SR replaced a EtherRegen Gen1 and it was a huge leap up in every category. I had read great reviews on the PhoenixNet so I purchased it and spent over a month comparing the two once the Innuos was fully broken in.
The SR is great sounding switch especially with a Shakti stone on top (a must have for every streamer). Of the three switches the Shakti stone brought the largest improvement to the SR. The SR had a better dynamic contrasts, what I call the jump factor, but the Innuos had far better harmonic information and significantly better density within the soundstage and a move obvious refinement. Overall given the trade offs, I sold the SR.
The Tempus hopefully will reinject the jump factor and keep the refinement of the PhoenixNet. Over next month, once the Tempus is fully run in, I’ll make some the comparisons between the two switches and post my thoughts.

Sigh. I'm still hoping the EtherRegen Gen 2 shows up soon.
You have my attention. I may evaluate a Tempus upgrade over the PhoenixNET. Take your time and keep us informed.
I guessed correctly on the Master fuse, per Andy, a top person at SR:
"Yes, we always use Master fuses in the switches we use in our reference room and at shows. It’s been universally beneficial in every setup we have done so far."
I have an SR switch on the way with that fuse and upgraded Euphoria SX AC cable. I really liked the Euphoria SX AC cable on my ground block where it made a large difference. Vangelis, do you think you had the stock AC cable on your SR Switch? I ruled out Dejitter It SwitchX due to higher power draw and concerns about climate change. Does anyone know the power draw of the Tempus? I hope to buy a smaller Microtik or other switch to front the audio switch and use vlans to separate the broadcast traffic, but first need to decide on a new house router.

I also ruled out the SwitchX due to the requirement of dual routers and a proprietary second IP address.
Fuses, power cords and of course my Shakti stone has constantly improved the sound from switches and streamers in my system. I never used a stock pc with the SR Switch. I did compare a mid level Nordost and a SR Foundation power cord but the Atmosphere SX Excite was clearly the better with the SR Switch. Euphoria SX is supposed to another big leap over the Atmosphere SX Excite, but I’m absolutely frightened to audition one, since I would likely end up with five Atmosphere SX Excites I would be compelled to replace. I have to imagine a Euphoria SX and Master fuse would elevate the SR switch beyond what heard. I have a friend planning to order a SR packaged in the same configuration.
I've just ordered one of these:
Ubiquiti USW-24-POE UniFi Gen2 24-Port Layer 2 Managed Gigabit PoE+ Switch w/ 2 x 1GbE SFP Ports, 16 x PoE+ Ports & 3-Year Hosted Cloud (95W)
My house network consists of fibre internet, 5 wired Ubiquiti access points and a collection of switches and PoE bricks acquired over the years that can be consolidated into this single switch. The audio is sent over a dedicated fibre connection to the streamer. I intend setting up a VLAN for the audio SFP port on the switch.
The only other device it will need to attach is a Buffalo network drive that hosts my music library. I can plug that into the Unifi switch (which is on a different floor of the house to the hifi) or the back of my streamer (Innuos Pulsar, has a second ethernet socket for that purpose), either way it will be on the new VLAN.
