  1. Absolutely delightful reinterpretations of her catalog
  2. I was all excited to get a USPS shipping notification within about 30 seconds of Alex’s post and got pumped! Alas, it was for a different package from Chicago. 8801 standing patiently by
  3. Saw the film last night. One of the most extraordinary concerts I've ever seen, and the soundtrack captures it perfectly. I urge folks to see the film in theaters if you possible can ("Stones" by itself is worth the price of admission...that performance will be etched in my memory for a very very long time)
  4. I believe the three SR7's per month is for the standard commercial SR7 build (PHL, based on Paul's designs, not built by Paul). Paul himself is doing the custom builds, so it will take as long as it takes him to work his way through the list. At one custom build a month, I'll have a nice Christmas present next year, but who knows what is reasonable for Paul to be able to do with all the other things going on (it is what it is) When I ordered my SR4 from PHL, it did arrive within a month of the promised time, so I have no reason to doubt that Mark and team would be able to deliver on the timelines they post for the PHL models. Great product, and something to help tide me over until my 3 DR rails are ready
  5. I'm #31, not sure how long the queue is. Alas, I don't move up when someone else cancels. In an ideal world, it seems fair that everyone that wants out gets a full refund (assuming no money has been spent on parts for that build), and the rest of us move up in the queue, at least until Paul has had a chance to catch up. That being said, Paul was very clear about his policy when I placed my order, and I knew going in I'd need to be patient.
  6. That is true. That was an experiment on my part (benefit of better power vs the cost of compromised isolation). The figure in the reviewcan be confusing, since it has a lot of the different configurations I was fiddling with. What I am currently running is LPS 1.2 to the clean side of ODX (closest to DAC) and a PowerAdd Pilot2 laptop battery to the dirty side of ODX. I found the LPS 1.2 to have more of a positive impact on the clean side. I have not yet had access to a third LPS 1.2 to try having one on both sides of the ODX (my other LPS 1.2 is powering my ISORegen)
  7. Doh! I meant I recommend the ODX very highly, not that my write up is highly recommended (too late to edit my post...oops). I'm glad it is helpful to you. Good point on DC cables Ken. When I did my tests, I had more limited collection to draw from. It may be worth revisiting now that I've invested in more Ghent DC cables to play around with.
  8. The ODX does filter above a particular frequency (it is designed for 768kHz). TBD whether 10MHz would get passed cleanly. That being said, I wouldn't be surprised if the quality of the clock signal isn't degraded by an electrical to optical to electrical conversion. Worth a try though. Here is my crazy write up of experiences with the ODX (highly recommended) https://www.head-fi.org/showcase/audiowise-opto•dx-optical-isolation-bridge-for-dual-spdif.23757/reviews#review-22155
  9. This I believe. I have developed a deep distrust of the PHY receiver chipsets out there, because that is the only thing I can think of to blame.
  10. I actually prefer the other notation with the stock Lush^2, but it broke down when I added a second black wire for my 4th shield layer Numbering the layers from inside to outside has helped me visualize what the different configurations physically are. For instance, for me having the USB ground layer physically closer to the data signal seems to be better than having it connected to the outside JSSG360 pair. What does that mean? Wish I had a hypothesis other than the ones that I proved wrong with these last series of listening tests
  11. Complete madness! Kidding aside, it still blows my mind how different shield configs on the Lush^2 can sound so different, and that has always nagged at me. Above experiments are about me trying to understand how different configs can sound so different, and test some hypotheses. At this point, I would not recommend anyone add a fourth layer, except to experiment.
  12. This was originally discussed in the "Novel" thread, but it seemed more appropriate to post some initial impressions here. Based on some posts by @Bricki and others, a couple weeks ago I added a 4th shield layer to my two Lush^2 cables, and I've been experimenting with various configurations since there. Some belated listening impressions (with thanks to @Bricki for the inspiration). For the below, here is my labeling convention for the various shield configurations: 0 (Lush^2 Black wire - USB ground) 1 (Lush^2 White wire - inner shield) 2 (Lush^2 Yellow wire - middle shield) 3 (Lush^2 Red wire - outer shield) 4 (new wire - added outer shield) Before adding the 4th shield layer, my Lush^2 configuration of choice was JSSG360^3 (A: 1-2-3 B: 1-2-3). Before that I was using JSSG360^2.5 (TANF) (A: 1-2, 3 B: 1-2-3) With standard Lush^2, I preferred the JSSG360^3 configuration: a bit darker and more relaxed, without a loss in detail. I added braided shielding to both my Lush^2 cables, attached a solid core wire at both ends, and then insulted and wrapped the wires. Pro tip: if you use an appropriate gauge solid core wire, it slides nicely into the jumpers on the end, making it easy to experiment with the Lush^2 connection strip. First, starting with the JSSG360x2 (A: 1-2, 3-4 B: 1-2, 3-4). My initial impression of JSSG360x2 was very strong, and I preferred it to JSSG360^3. However, after some extended listening tests, I was finding the extra vividness to to be a bit too much on some more challenging tracks. That was motivation this weekend to step through some additional configurations to see what patterns I could see. Alas, in a fit of unusual efficiency, I had added a 4th shield layer to both my Lush^2 cables at the same time (one from NUC 7i7 to IsoREGEN, and one from ISO Regen to Matrix Audio XSPDIF2, which then connects to my Hugo mScaler by Toslink). This meant I didn't have an easy way to compare the 4 shield configurations with the usual 3 shield Lush^2 configurations (DOH!) Below notes that compare to a standard Lush^2 are from memory, and should be consider a plea to someone with more foresight than me to test a 4 layer config against a standard 3 layer config. JSSG360x2bullseye A: 1-4, 2-3 B: 1-4, 2-3 A JSSG360 pair nested between a JSSG360 pair. This definitely got my attention: Cleaner/darker sound, less high energy, more relaxed presentation. It retained the air and resolution of JSSG360x2, but cleaned up some of the fatigue I was sensing on some more challenging tracks. I preferred it to JSSG360x2. The new top dog. JSSG360x2link A: 1-3, 2-4 B: 1-3, 2-4 Clean, but more high end energy than the bullseye config. Still seemed a bit better than 360x2, but still a bit fatiguing on the more challenging tracks. Bullseye still in the pole position. JSSG360^3+ A: 1-2-3, 4 B: 1-2-3, 4 Same as my original favorite JSSG360^3, but with the 4th shield layer floating above it. Seems brighter than the 360^3 that I remembered, and more fatiguing. Not sure if leaving the 4th layer floating is a wise thing to do. I still prefer bullseye. JSSG360^3.5 A: 1-2-3, 4 B: 1-2-3-4 Cools things down a bit, and takes away some strain, but still brighter than I remember with JSSG360^3 before adding the 4th layer. Still prefer bullseye. JSSG360^4 A: 1-2-3-4 B: 1-2-3-4 Better, but still seems brighter than I remember the JSSG360^3 (and yes, at this point I'm kicking myself for not leaving one Lush^2 cable with the standard 3 layers) Makes me want to go back to Bullseye. So based on above, I went back and reread some of the original JSSG360 posts and discussion. In all the above configs, the USB ground line (Black on the Lush^2) was disconnected, meaning the shield layers were floating from the source and destination. What would happen if I started bringing USB ground back to the party? JSSG360+360^3 A: 0-1, 2-3-4 B: 0-1, 2-3-4 This config connects USB ground from source to destination but leaves the 360^3 layers still floating. Still too much brightness for me. JSSG360x2s A: 0-1-2, 3-4 B: 0-1-2, 3-4 (favorite) So what happens if the inner JSSG360 pair is connected to USB ground on both sides, and the 2nd JSSG360 pair is floating? This is a winner! Great detail, less harshness than 360x2 with the more challenging tracks. This is currently my new favorite. JSSG360x2s1 A: 0-1-2, 3-4 B: 1-2, 3-4 JSSG360x2s1’ A: 1-2, 3-4 B: 0-1-2, 3-4 So what about floating USB ground on one side or the other? Still keeps the great air and detail of the 360x2s, but is a bit harsher on more challenging tracks. JSSG360x2bullseyeS A: 0-1-4, 2-3 B: 0-1-4, 2-3 So how about adding a USB ground connection to bullseye? Would that bring it even with 360x2s? Not quite. Definitely cleaner and with less high end energy than bullseye, but I am finding myself wanting to go back to 360x2s With the initial survey done, time for some extended listening with JSSG360x2s. With that new baseline, I may be tempted remove the 4th shield layer on one of my Lush^2's, and directly compare JSSG360^3 to JSSG360x2s. Empirical listening aside, I'm still trying to get my head wrapped around the field dynamics in play when you have this many shield layers. Given that I still don't have a hypothesis for why JSSG360^3 would be better than JSSG360, the complexity of having a 4th layer makes it even harder to understand why one config sounds different than another. When are layers an antenna and when are they a Faraday cage? In aJSSG360 config, aren't they both at the same time? I need to ponder this some more, with something stronger than sparkling water.
  13. I was able to add a fourth shield layer to my Lush^2 cables earlier this week, and I agree that JSSG360x2 is a definite new favorite (absolutely dark backgrounds, no loss of real detail or resolution, very very relaxed and stress free presentation) Coming from a JSSG360^3 config, impact was immediate and obvious. Thank you @Bricki for doing the additional experiment and reporting your findings! I have a bunch of configurations I plan to test this weekend, mixing and matching the 4 shield layers in different ways For the Lush^2, assuming these wires (from most inner shield to outside shield): 1 (White) 2 (Yellow) 3 (Red) 4 (new - block/stripe) I will be testing these configs: JSSG360^3+ A: 1-2-3, 4 B: 1-2-3, 4 JSSG360x2 A: 1-2, 3-4 B: 1-2, 3-4 JSSG360^3.5 A: 1-2-3, 4 B: 1-2-3-4 JSSG360^4 A: 1-2-3-4 B: 1-2-3-4 And for fun: JSSG360x2link A: 1-3, 2-4 B: 1-3, 2-4 JSSG360x2bullseye A: 1-4, 2-3 B: 1-4, 2-3 Hard to imagine something better than what I'm hearing with 360x2, but very excited to find out!
