  1. Not being able to listen to all files being upsampled to DSD512 (even though your DAC is 512 capable) is common due to your computer not having enough computational power to complete the conversion quickly enough. There is lots of this discussed under Software-- HQ Player. CJH
  2. Miska--I tried a straight USB connection with a two different USB cables (Belkin Gold) and still having problems. Following up--I contacted Drop about my misbehaving D70 and they said: "Contact Topping, thank you for giving us your money--have a nice day" . I will not purchase from Drop again due to the lack of responsible customer service. Hopefully, Topping will come through with a working unit and it won't cost me $$$ in shipping charges. I will say for the few minutes I got to listen to the D70 at 768--it sounded quite good. CJH
  3. jabbr--just wondering if you ever got your D50 working with HQPlayer. I have a D70 and am having problems with HQPlayer/Rendu as well (always works with my iFi Micro DSD BL). Can't get DSD working and when I play PCM it works for about 10 minutes than I get a continuous blast of full volume noise-no matter what the HQP volume is set at. My speakers won't take this too many times longer until I lose a tweeter or two. CJH
  4. Not sure why you want 2 RJ45 connections to your JCat. My thought was to use the optical connection from both Sonore optical modules and an optical connection from the etherRegen into the Mikro Tik CRS305 since it has four possible optical connections (no use for the RJ45 connection of the CRS305). Then use one RJ45 connection from the etherRegen to your JCat. Total optical isolation and great clocking going into the JCat. CJH
  5. Hey Nenon how about lose one EtherRegen and replace with a multi SFP switch like Mikro Tik CRS305 (at $153). Both Optical modules can plug in as well as one EtheRegen feeding one RJ45 to the JCat. CJH
  6. Sorry, my mistake (wishful thinking) I have a microRendu that only accepts 10/100. So I guess the oM won't work for me. CJH
  7. Would like to try an oM but I have never been able to get my uRendu to work with anything except 10/100 (FS-105). I have three 10/100/1000 switches and my uR will not work with them. CJH
  8. Is there going to be a version with Male C-USB plug? CJH

    Glass cd's

    My recollections are from more than 15 yrs ago and are a bit sketchy. I wish Winston Ma (FIM) were available to answer these questions but sadly passed away in 2016. No mastering trickery was applied. It was simply a higher quality process of producing a CD disc. Pit errors are a result of the CD manufacturing process with a typical disc having perhaps 100-150 errors per disc. The JVC UHQCD process is a refinement of the CD manufacturing process and I believe the errors these discs averaged is around 25. The FIM glass discs averaged 4-5. Each disc included a multipage booklet explaining the process. Most of these discs were sold in the highend Asian market, but surely someone out there has one of these discs and can provide more accurate and comprehensive information. Since Reference Recordings did some of the FIM recordings, I would speculate that Tam Henderson or Keith Johnson has one or more of these discs. CJH

    Glass cd's

    Glass CDs have been around for quite a while. I had the privilege of visiting Winston Ma of First Impressions Music back in the early 2000s at his home and was treated to hours of listening sessions on his exceptional audio system. He was an early promoter of the glass CDs and had a few of his recordings done as these "glass masters". He likened them to direct to disc LPs and had documentation of the lower error rate for each disc compared to even the UHQCDs. While its been a very long time, I still remember the exquisite sound of these discs. Yeah, they sounded quite a bit better. At the time I believe he was selling them for around $150 each. CJH
  11. USB in > optical isolation > USB out. Using USB in to power the first optical stage and external power for the second optical stage and USB out. Let's call it IsoptoRegen. CJH
  12. Is it possible for John S. to design a USB optical isolator using this technology? CJH
  13. Musikfan & iLguapo: Check out www.fs.com for quality modules and cables at reasonable pricing. CJH
  14. austinpop: Good question as I have tried just adding additional ethernet cables in the past (what sgr is doing) and it simply seems to confuse the switches and I loose internet connection. There has to be more to it. Let us know Steve. CJH
  15. the_doc735: Sorry, I'm old and have no idea how to make diagrams in these forums. Chris H.
