  1. GREAT review, Rajiv!! As usual, you take more time and effort, and exceed all expectations! Very illuminating with specific POVs that still allow us to ponder, but now with more and better info. Congrats to @JohnSwenson and Alex for creating a great new switch at an affordable price!
  2. Rajiv -- thanks for all you do! I'll be glad to share what I've done, as I am enjoying sounds I never would have imagined (compared to where I was) without the help of this forum's contributors and you. Know I am not a DIY (although I did manage to create add the JSSG shielding to my Lush cables!), so my process has been to read the discussions in this topic, learn and pick my spots. I got engaged Summer 2017 and the attached schematic is where I am presently. My system has been developed almost entirely from information uncovered in this topic thread, personal messages with Rajiv and a few others, and one fun trip at the outset to meet and learn from @austinpop and Eric in Austin. I have adopted SQ recommendations from most of the areas discussed in this thread. Importantly, in many areas I have ratcheted up SQ by adopting second and third-step improvements all of you have uncovered in your never-ending quest for the best. Examples would include servers, endpoints, power supplies, cables, shielding, sequencing of devices, location of cores relative to endpoints, the move from lower to higher power voltage, and more. I wish I could say my system benefitted from all the items in Rajiv's list, but it doesn't. Having said that, I do believe I am hearing SQ at levels that make me very glad I started down this rabbit hole and invested a not insignificant amount of time and money to get here. It's my opinion every person goes through a SQ Continuum. Let's say there are 6 stages from poor SQ to the "best". At each stage of relative improvement to my system, I was blown away by the change in SQ, and couldn't really imagine how things might sound better still, and no idea how to get there. However, the inertia and contributions of the members on this forum topic kept teasing me. I read over and over again about higher levels of SQ I couldn't imagine, so decided I better stay tuned to this channel! I'm sure I've only made it thru 2 or three of the SQ improvement phases, but I can't believe how good the music sounds. Thank you to all, most of whom have unwittingly helped me get to this point. I don't do much A/B testing for lack of interest (I have all of you for that!), and to do so is very difficult with the cramped quarters in which my system is housed. My observations in terms of SQ equipment mirror what I've heard here, but I dare not try to identify them in rank order because I have not done the critical testing. I also believe what most you say here - every system set up will have different points of inflection. - Power supplies: Who among the uneducated would guess this?! Whether it has been the LPS-1, LPS 1.2, or now the PH SR-4, these devices make a tremendous difference. Also, moving from 7v to 12v (or higher) also provides greater torque and SQ, or so it seems. - USB regenerator: My modded SOtM tx-ultra has provided a nice bump in SQ from the get go. But things get better with better power, as I'm learning. - Reference Clock - I've only had one: the Mutec, and when combined with Habst cables, it definitely makes a difference. I wish more devices had ports for a reference clock. - Cables: I was slow jumping on this one, but having made a leap to more significantly-priced power cables (Cardas Clear) in particular, I hear nice improvements in SQ. Ditto for the Lush USB interconnects and the Ghent/JSSW 360s. - Server/Endpoint/Player - I've enjoyed the MicroRendu, UltraRendu, and Zenith SE as endpoints. All gave me great improvements, but equipment like the SE really move you to a different phase of the SQ continuum. I've had my Roon Core and Player both in the Zenith, but separated them, as I felt even if the iMac is sub-optimal vs. Epiphany and NUCs, SQ is better when there is a switch in between the Core and Endpoint. And as many have pointed out, I apparently can take that still further, and add a second switch in between for more upside. I've gone on long enough. Thanks to all, and I'm looking forward to adding another SR-4 with Cardas Clear in early October. I hope to have a period of prolonged "listening" at that point, but I know all you will make that hard to do! My Music Topology 08.22.19.pptx
  3. @austinpop So Rajiv, what is the server you have embedded Euphony + Stylus into? Is it the one you had built for yourself?
  4. I have now added artwork for whatever was missing among 1845 artists. Each is sized to fill the screen (rectangular) and in png format. Everything has slowed to crawl. Search. Play. Everything. Pls help me fix this picture.
  5. @Thank you for the nice introduction, @Superdad I just got my new SOtM 9v switch today - with CLK, 75ohm REF10 port, silver, the whole enchilada. Installed nicely and powered by the UpTone LPS 1.2 which I enjoy more than the standard SOtM 9v power supply. My baseline was a SOtM-modded Netgear FS108 switch pigtailed to the SOtM txUSB ultra so the switch would take advantage of the ultra’s better clock, as well as the REF10/Habst cable the ultra had been modded to accept. Now the REF10 directly controls clocks on the USB ultra and new SOtM switch. I’m only 3 hrs. into what SOtM says is a 50-hr break-in. I will say, though, the combo (new switch with mods, direct REF10/Habst connect snd LPS 1.2) is already providing enough of a SQ bump to make me happy with the purchases. I already had the second Habst cable and LPS1.2 on hand, so my new investment was less than it would have been otherwise. Although I knew the dimensions, it’s size -for a switch - still surprised me. It looks great and I don’t find the size to be an issue. It’s just uniquely different. I’ll report back when I’ve gotten thru the break in!
  6. Thanks and Happy Holidays to Rajiv, Eric, Romaz and all the other CAs for sharing their time, knowledge and experiences. My SQ compared to original has improved more than I could imagine over the last year. While more a beneficiary than a contributing experimenter, I hope to soon share some thoughts on SQ impact when I: - replace an SOtM modded Netgear108 with the new SOtM switch (with upgraded capacitors + silver) - replace the pigtail from the tx-USB ultra’s clock and REF10 with rhe REF10/Habst directly cabled to the SOtM switch. In the new configuration , the SOtM tx-USB Ultra and new switch will both have the CLk and a direct REF10/Habst Input. I’ll try to share what my ears hear as best I can! Bruce
  7. Thanks, Alex. Look forward to Feb when you hit the market and we can hear the results of this labor of love. Since I’ve already invested in the REF-10 it will be easy to A/B and pick the best path for my system and ears!
  8. Sorry, if I missed this, Alex. Will your EtherRegen have a Reference clock input port?
  9. Thanks on the cable debate -50 v. 75 ohm- question asked and answered!
  10. Thanks! I will be using Habst which is available in either 50 or 75 so that won’t be a consideration with me, but I appreciate your reply. In your opinion there there is no real difference. Would you feel the same if a 75 cable is used in a 50 ohm REF-10 output to a 50 ohm input? thanks.
  11. Different Question: is 50 or 75 ohm optimal for use with my REF-10? Most of what I read in this forum or others seems to suggest 75 is better. Here’s what May/SOtM told me: -> Normally 10MHz signal use 50 ohm cable. And word clock or SPDIF signal use 75 ohm cable. If you want to connect audio signal or clock signal in long distance like CATV signal, the 75 ohm is better. But, for most cases, audio application is not needed to connect in long distances. So 50ohm cable is better than 75 ohm cable. Do you agree with this?
  12. Rajiv, it’s not you. I’m just easily confused! Thanks for the additional clarification.
  13. Rajiv - I don’t think you use a sMS Vsnilla/Neo in your regular setup do? You use the SE for both Core & Roon Ready and then strait into the tx-USB ultra? I’m taking a step back here, but does the idea @romaz presented - and that is at play in your neo vs. vanilla test - that adding the additional switch and Roon endpoint after the Server (Core) improves SQ? If I recall romaz preferred the mR to the uR in this configuration?
