Popular Post lmitche Posted December 13, 2019 Popular Post Share Posted December 13, 2019 For those that are interested, unfortunately after several days, the Dacrown cables never shipped. Perhaps the white cable order meant that supply was constrained. Disappointed, I cancelled the order and did some additional research on Cat 8 cables. Findings included reports that the Dacrown, and most other Chinese Cat 8 cables, fail when measured against Cat 8 standards. It occurred to me that there should be "authentic" Cat 8 cables made by a credible manufacturer. After much browsing, the Cables Matters Cat 8 showed up. This is a Massachusetts based company and their Cat 8 reviews look good showing cables that measure well. The price was competitive so I ordered a couple instead of the Dacrown. The short one, 3 feet, arrived this morning, the long one, 10 feet, is a day late and still hasn't arrived. The connectors are the best ever seen here and are clearly industrial strength. Unfortunately the cable seems just as stiff as the BJC 6a. When the second one arrives, I'll test this pair against the Tera Grand premium. It will take a few days to break in of course, so stay tuned. FWIW, people are asking about my comment that the ER enables upstream tweaks to be more audible. It has always been my belief that much of what we hear as SQ quality enhancements, are largely due to improvements in timing. This timing impact is often masked and as we tweak various components and subsystems, both the timing related problems and improvements are revealed. The ER subtracts several types of noise from the chain, and adds better timing for the signal, unmasking and thereby making tweaks audible by exposing timing improvements from upstream components. The recent cable experiments here reveal greatly improved focus, like the sound is better time aligned, coming from a single point in space, rather than a larger blob in the image. This also means that the space between sources is much darker. The perception of realism and presence is at a new level. I hope this is all clear. I wish we had the tools to measure small but perceptible timing differences. Larry pas, lwr and gstew 1 2 Pareto Audio aka nuckleheadaudio Link to comment
HumanMedia Posted December 13, 2019 Share Posted December 13, 2019 My system is wireless endpoint to ER, to UltraRendu, to DAC. The UltraRendu is on its own JS-2. I know if I put the ER on the other output of the JS-2, it is not recommended, shared 0v etc. But what if the other JS-2 output was charging an LPS 1.2? And the LPS 1.2 powered the ER? Would this break the shared 0v and be OK? Link to comment

MikePid Posted December 14, 2019 Share Posted December 14, 2019 In preparation for my 3rd batch ER, I had the opportunity to upgrade the last leg from my cheap D-Link switch (powered by ifi SMPS) from the well-regarded BJC CAT6a to a custom Supra CAT8 with Telegartner connectors, which just arrived today. Holy crap! Even though it isn’t broken in yet, what a huge improvement! Much more 3D and listenable. When I put the BJC back in, it sounds compressed and distorted. I tried it a few times to make sure. Maybe I don’t need the ER after all 🤣 LOL. The last leg goes into an ultraRendu (powered by a recent upgrade to the new Sonore LPS) which goes partway towards a Signature Rendu. I have no idea how the ER can improve on this but it seems like it will. In the meantime I’m enjoying my music more than before. Bottom line is the Ethernet cable upgrade makes a big difference in my system, even without the ER. gstew 1 Link to comment

Ricardo, I have zero expertise with in wall ethernet cabling and related safety standards for plenum rated cabling. You might call Blue Jeans Cable or Cable Matters. I expect both companies will have answers for you. We may never know if the Chinese goods meet US safety standards. Pareto Audio aka nuckleheadaudio Link to comment

The “A” side of the EtherREGEN has both of these wired in along with a WiFi router (Eero mesh). As I understand it, I should connect the ground on the EtherREGEN.

Just checking for any other recommendations on noise mitigation or placement for the EtherREGEN. Unfortunately the exact "ground" to use for "BEST" results is not necessarily easy to figure out. The simple answer is any socket connected to safety ground. There MAY be very subtle differences with connecting to grounds from different circuits. You can certainly try different sockets if you have different circuits near the ER. The best is usually the closest to the ER so you use the shortest ground wire. John S. Link to comment

I’ve got the following receptacles and current connections that are all within inches of one another: a) a 20a circuit which currently being used by my Denali (it’s supporting analogue devices); b) a 15a circuit currently used by a low output wall wart for a Synergistics Research FEQ. So I can use an available receptacle on either of these circuits. In either case the banana to spade cable is 1.5m. Will either of these of these work? Any preference? Or should I simply connect the ground plug to a receptacle on the Denali? This grounding stuff is a mystery to me...

HumanMedia Posted December 14, 2019 Share Posted December 14, 2019 Are there any disadvantages / advantages to using different input voltages to the ER? Is more heat generated using higher input voltages, being regulated down? im in a hot part of the world with temperatures over 120 Fahrenheit due in the coming months, so I will go for whatever keeps things cooler, unless there is a compelling reason to do otherwise... Link to comment
JohnSwenson Posted December 15, 2019 Share Posted December 15, 2019 The voltage range is from 7 to 12V. It generates the same amount of heat no matter what the voltage is. There may be some people that hear a slight sound difference with different voltages, but there is no specific engineering reason for choosing one voltage over another. John S.

It will take a few days to break in of course, so stay tuned. The Amazon Gods were a bit kinder to me than they were to Larry. Today I was able to followup my cable listening tests last week with the new contenders. As background, here is a link to what I posted last week: For this followup test, I wanted to listen to some more CAT8 cables (vs the Dacrown Cat 8 winner from last week), so I picked a random Amazon CAT8 cable (Phizli) and got a Cable Matters Cat 8 (all in black of course). I also picked up the premium Tera Grand Cat7 cable that Larry mentioned in his write up (vs the flat cable that I had last time). All tests were with no break in on the cables. I still have my EtherREGEN still powered by a Paul Hynes SR4 @ 12V, with a Tera Grand 6’ Cat 7 cable connecting it to my ethernet wall jack. In my closet, I have a stock MacMini running Roon Core. However, since I’m done with my power supply experiments with EtherREGEN, I now have my ER connected via various cables under test to my NUC i7 (Euphony running HQPlayer Embedded, powered by PowerAdd Pilot2 battery at 16V) connected by a Lush^2 USB cable to my new SoTM tx-USB ultra (stock, powered by Uptone LPS 1.2 @ 12V) then Lush^2 to Chord DAVE to Voxativ 9.87 speakers direct. Here are the cables that were invited to round 2: WALL TO ETHERREGEN: Tera Grand (6’) CAT7 10 Gigabit Ethernet Ultra Flat Patch Cable ($8) https://smile.amazon.com/gp/product/B01F7MLJU0/ RUNNER UP FROM LAST WEEK: Tera Grand (3’) CAT7 10 Gigabit Ethernet Ultra Flat Patch Cable ($8) https://smile.amazon.com/gp/product/B01MQHD96X WINNER FROM LAST WEEK: Dacrown Cat 8 Ethernet Cable 5’ Shielded ($8) https://smile.amazon.com/gp/product/B07QZH6C8F NEW: Tera Grand (3’) CAT7 10 Gigabit Ethernet Premium Patch Cable ($7) https://smile.amazon.com/gp/product/B00G4M4FIG NEW: Phizli Cat8 Ethernet Cable (3’) 40Gbps, 2000Mhz with Gold Plated RJ45 Connector ($8) https://smile.amazon.com/gp/product/B07XNZ2CGH NEW: Cable Matters SFTP Cat8 Ethernet Cable in Black (3’) ($12) https://smile.amazon.com/gp/product/B07NVS8BF5 Like last week, I mainly focused on bass detail/imaging, and dynamics (a good tell for me for what ER brings to the table. I used several test tracks, but an example is Till Bronner "A Thousand Kisses Deep" from Nightfall, and Diana Krall "The Boulevard of Broken Dreams" from All For You. For this eval, I was mainly focusing on the sense of space and presence I'm getting from the bass, but the benefits of the ER (as I hear and many have reported) are more than that. Here are my very subjective ratings after sweeping through these a couple times: Tera Grand Flat Cat 7 6 (baseline from last week) Dacrown Cat 8 8 (baseline from last week) Tera Grand Premium Cat 7 8.5 (a bit more bass attack) Phizli Cat 8 9 (clearer, and maybe a bit better attack) Cable Matters Cat 8 10 (even more clarity and attack) The Cat 8 cables were generally better than the Cat 7’s, but there was variability from cable to cable, and even overlap (the Cat 7 Tera Grand Premium did better than my favorite Cat 8 Dacrown from last week). As a last test before I called it a night, I wanted to check whether the cable on the A side of the ER (connected to the wall in my case) make a difference? With the new favorite Cable Matters Cat 8 on the B side to my NUC, I compared having my random ethernet cable from a box (lowest rank last week on the B side) to the Dacrown Cat 8 from the wall to the ER (last week’s winner on the B side). With a confirmation bias squint, is there a difference? Maybe so, but maybe not. I think it would take an extended critical listening test to suss out differences. At this point, the delta is not enough for me to really worry about. Since the Cable Matters cables are so reasonably priced, I’ll get another one (black of course) to put on the A side to the wall, and not think about the A side any more. As a next step, things are still stepping up enough that I suspect there is more to be had on the B side than what the Cable Matters Cat 8 brings to the party. If I have time over Christmas break, I may try to do some experiments with adding JSSG360 shielding to this cable to see what happens. Of course, as we hear feedback from people using the EtherREGEN with the Phasure ET^2 ethernet cable with different shield configurations, all the better! Larry, thanks for the pointer to the Cable Matters cables (their Cat6 cables are my go tos in the rest of my house).

Popular Post RickyV Posted December 15, 2019 Popular Post Share Posted December 15, 2019 I already had the parts and with my new ER I got renewed inspiration to built a new Ethernet cable. My previous and the new cable both use Supra cat8 cable as a base. I have seen the ET^2 cable and I have the lush^2 so why not make my own. So at the heart of the cable is the Supra cat8 and over that go two layers of braided tinned copper shields separated by electrical tape. Every shield has it own connecting wire ( white, yellow and red). White being the shield of the supra cable. On one side, the ER side, I also made a black wire to possibly connect to the ER ground screw and is also connected to the metal connector. I have not experimented yet so it’s on A:wyr B:wyr. Oh it took me about 5 hours make. Bricki and Avalfa 2 Meitner ma1 v2 dac, Sovereign preamp and power amp, DIY speakers, scan speak illuminator.

I am thinking of trying the telegartner connectors on my jssg360 x 2 Supra cat 8 cable... Once I get my ER I'm thinking of shortening this cable and putting the telegartner connectors on it.... I'll be interested to know how your new cable is sounding once it's settled in 👍 Link to comment
