  1. According to who? That is typically the case for power cords - best cord from wall outlet to power conditioner. For ethernet, I gather most would put the best ethernet on the last link to endpoint/renderer. For ethernet I suggest trying ... switch > fibre (isolation) > best ethernet (low noise transmission) > endpoint. Why did you choose this? I agree with this 200%. However the outside world that is in your listening room can infiltrate cables and connectors too - so another place to stop noise is where cables connect to components. And finally, the outside world is a useful place to dump noise via ground.
  2. My next instalment of this journey is ... I had in mind putting an ECT in my endpoint (Devialet), probably on the ethernet isolation transformer. But instead I interrogated ER further. After reducing noise by having only fibre into Side A, is ER somehow still passing on or generating noise? My test was another ECT at the Side B port. Unfortunately this is the closest an ECT can be put to the pcb traces to the port. The ECT is on a heatsink for the ethernet format converter, buffers and flip flops (see below). To its left is Side B port. Just in front of that is the clock. Did it make a difference? Yes! Similar to improvements gained from recent change to fibre, but perhaps not quite as much. To put it in perspective, the ECT at US$60 had a similar magnitude of improvement as when I subsequently changed from ER > WW Platinum > ISO CAT > SR Atmosphere X REF to ER > JCAT Signature > ISO CAT > SR Atmosphere X REF The JCAT is US$350 more than the WW, and in a different config earlier in my journey here was significantly better than the WW. Maybe a greater improvement from the ECT could be gained if using ethernet from Side B to endpoint that reduces noise less than what I have there presently. Next will be to see if grounding ER to Synergistic Research Ground Block will help any further.
  3. So that could be 3 layers of isolation in 2 boxes. sources > ER1 SB > MOAT > ER1 SA > fibre > ER2 SA > MOAT > ER2 SB > EP Acheiving this with OMs could be sources > OM1 > fibre > OM2 > 2nd BE > OM3 > fibre > OM4 > 2nd BE > OM5 > fibre > OM6 > BE > EP A lot less tidy, more power supplies + cords, potential degradation from 2.more ethernet cables, and 5 -6 OMs at nearly US$500 + extra ethernet cablea more! Sure, OM1-4 could be TP link or whatever. But what is better isolation: ER MOAT or fibre via OM? A key benefit of 2 ERs could be that Side A and B are governed by the same clock. I'm gonna ask Alex if that is the case. It is possible the SOtM cable is just highlighting noise elsewhere. When I changed footers under my Devialet I had a similar issue - I got more good stuff and bad stuff - and then I put an ECT in the Edgeswitch that was in use then and the bad stuff was reduced significantly and good stuff got better!
  4. Well, I tried this. Actually for me it is this ... Sources > SS > Fibre > ER SA > MOAT > ER SB > WW Platinum > ISO CAT > SR Atmosphere X Ref with ECT on EP connector > EP This is another small improvement. Vocals more focused, more apparent depth to image, more strongly defined and solid bass, less smear of siblances. Lots of other improvements come along with these. For a while a key indicator of improvements for me was cymbals. They seem to be right in the part of the audio spectrum which really highlight the presence or reduction of noise. They can have a variety of sounds, each can have a range of ringing overtones and mixture chime like high frequencies, as well as explosive attack and long resonant decay ... or mellow shimmer. Go to a drum shop and bang a few, or ask a drummer to, to get an appreciation of how they should sound. In my system, cymbals are now very clear, dynamic, natural decay and have a great sense of 'space'. Now the remaining tell tale of noise is vocal siblances, especially female vocals. Like actors, singers train to pronounce those sounds clearly for better articulation. So I'm listening for how natural these sounds are ... ch, st, sh, sp, f, c, ch ... etc. If they are clear and natural, so will be lots of other things, such as guitar picking, and micro echos and cues. If I can get another similar scale improvement, there will be no siblances left.
  5. Silly me cant count ... that is 1 layer with OM and 2 layers with ER as per ... Sources > SS > fibre > ER SA - MOAT - ER SB > BE > EP Sorry! With your Phantoms you might go ... Sources + Dialog > ER SB > MOAT > ER SA > (2 x 2nd BE > OM 1 > fibre > OM 2 > BE > Phantom). This may cost less than a 3m+ run of BE. There are dual SFP port FMCs that may do well instead of OM 1 It is timely that I just stumbled on this ... while about OMs it covers some good fundamentals. https://www.audiostream.com/content/sonore-opticalmodule-review I got curious about what clock is in OM and came across this (BTW Superdad is Uptone Audio's Alex and John). ER is also referenced to an ultra-low-jitter/phase-noise Crystek CCHD-575 oscillator.
  6. How about ... SS = Standard Switch BE = your best ethernet cable EP = endpoint 1 layer of isolation = Sources > SS > fibre > OM or ER > BE > EP 2 layers of isolation = Sources > SS > 2nd BE > ER SB > MOAT > ER SA > fibre > OM > BE > EP It depends: - what is the best (ER or OM) just before EP. - what is the greatest source of noise - if your cables absorb noise (eg, JCAT, TotalDAC). I might try connecting my Edge server to the EdgeSwitch to get ... Sources > SS > Fibre > ER SA > MOAT > ER SB > BE > EP That is, shifting the noisy server from Side A to SS to put 2 x isolation between it and EP. You can see how Paul Pang got to quad switch and Afterdark got to dual optically linked switch. I'd say the moral here is ER is very good isolation, but SQ can be improved with additional layers of isolation. This really is a rabbit hole, um - warren!
  7. I've been meaning to share this pic of a US$6k Ansuz ethernet ... with cells!
  8. Well, I skipped plugging ES psu into power conditioner, and went straight to replacing AD with fibre. WO > WWS > ES > fibre > ER SA > ER SB > WWP > ISO > SR > EP Another incrementally minor improvement even though SFPs are fresh and not burned in. I cant imagine plugging ES psu into power conditioner will make any difference given fibre isolation. All these latest improvements are about 5-10 each as per my previous scale. Except ... whike putting the SR POD on my server before using Side B was 80, taking it off when Side B is in use made only say 20 difference ... oddly an improvement! Well, I felt with POD on server the sound was a little dark/dull and a tad more relaxed than when I took it off. But the point to this is that changes upstream on Side A still affect SQ via Side B, even if just a little. And ISO Cat added further refinement downstream of Side B. I liken this to more layers of paint on a sports car giving a deeper more pure shine. The ER has laid very good base coats ... now its more clear coats, and polish. Its from Core Audio Technologies, now out of business. He made LPSs for audio PC servers. The DC Cable is also a bit fancy, but I can't remember in what way. Edit: It is called Kalos, this is inside it.
  9. My tinkering eith EdgeSwitch is to see what can be achieved. The only noisy thing connected to Side A is the Antipodes Edge, but its noise is quite reduced by the ECT and JCAT LAN cable. Now I have solved my problem, and explored some more ways to arrange cables, I will consider tweaking.
  10. Tonights instalment f more trials ... After lots of troubleshooting, my issue with connection of my network to Side A seems to be my in wall cable. To solve this, I put the Ubiquiti EdgeSwitch upstream of ER. Below is list of acronyms and steps underlining each improvement to the ethernet system. Throughout, there was no change to connection from ER SA to Antipodes Edge which remained JCAT Signature LAN. Also there is a Synergistic Research ECT on the underside of the connection to the endpoint. WO = Wall Outlet ES = Ubiquiti EdgeSwitch ÈR = EtherRegen SA = Side A SB = Side B Cables UTP = Unsheilded Twisted Pairs WWS = Wireworld Starlight WWP = Wireworld Platinum AD = Afterdark LAN (sheild not attached to connector at one end) SR = Synergistic Research Atmosphere X Reference ISO = SOtM ISO Cat EP = endpoint (Devialet) WO > WWS > ES > Cat 5e UTP > ER SA > ER SB > SR > EP Using Side B to connect to EP is superior to just ES and just ERSA. Not hugely though. WO > WSS > ES > WWS > ER SA > ER SB > SR > EP Removed SR POD from Edge - noted improvement, more life/liveliness and a bit brighter so more definiition Placed POD over Devialet Core Infinity Board - noted another improvement, cleaner. WO > WWS > ES > AD > ER SA > ER SB > SR > EP WO > WWS > ES > AD > ER SA > ER SB > WWP > ISO> SR > EP Each improvement was incremental, and combined to something between minor and moderate improvement. Next installment will be: - plug ES PSU into power conditioner - fibre to replace AD. Then remove ECT from connector and strategically place that ECT on ethernet isolation transformer inside Devialet.
  11. Thanks for all the interest - I didn't realise these would be so popular. All gone now.
  12. Does @Snoopy8 think the CPU heatsink on ER improves ERs SQ? How about some thermal paste? I have recently said elsewhere when sharing my comparisons between ER Side A only and my Ubiquiti switch with ECT , both with my hi end ethernet cables, lps and power cord ... ... the overall impact of the entire ethernet system is probably ... in the order of the benefit of a good power conditioner. I feel that is the best analogy, because a stock basic $40 switch and $5 Cat 5e cable is like using a hardware store grade powerboard with stock power cords. They both serve the purpose, and every improvement from that base is about improving signal transmission with less noise getting into the audio gear. And maybe that is where the next generation will be - ethernet conditioners where signals pass through 'cells' that suck the noise out, think Shunyata, Akiko ... Oh, look ... cells ... from the makers of power conditioners ... https://shunyata.com/products/digital-cables/ethernet-digital-cables/ethernet-cables-venom-delta-alpha-sigma/ https://www.synergisticresearch.com/cables/galileo-sx/galileo-sx-digital/galileo-sx-ethernet/ See also Ansuz powerboxes and attach pic of Ansuz ethernet cable. ... Rest assured that this experience demonstrates that the ERs MOAT is very effective. Previously, with my old switch, when I changed the Cat 5e UTP between switch and wall outlet to WW Starlight Cat 8 (triple sheild) the improvement was significant. However [with ER Side B MOAT], I cant be certain there was an improvement [changing from UTP Cat 5e to WW]. So that's a big plus for the MOAT. I note Gigafoil is an option for isolation. ER and Gigafoil are about same cost, but with ER you also get a good switch, integrated with the ability to send data across isolation of MOAT to endpoint without possible degradation from cable and connections. My current ethernet system (incl switch, cables, lps, power cord) is about US$4-5k rrp and I feel easily competes with the >$US8k rrp power conditioning (excluding power cords). But it is likely the full benefits of the ethernet system could not be appreciated without the power conditioning and rest of the system's resolution. PS. This is only relevant if any of your audio is digital files that are transmitted via ethernet.
  13. Oh, you should really put some fans on that big heatsink, the ones with blue lights, if not for SQ, at least bling! 😅
  14. Correct, that is what the BC stands for. The BC are considered by many as the sweet spot in terms of value for money at retail prices.
  15. Further information: I have 12 available, ie. 4 sets of 3, $140 ea kone, $400 per set of 3 including postage.
