  1. LPS1 is driving my iso regen and mixed opinions about replacing chords Wall mart. I burned my happy time secret Audio tokens on 2 intel NUCs and bits. So a cheap fully built studer can fill the wallmart gap and finally rid myself of them until i can afford an Uptone. Apologies to the Thread OP as other than Uptone i couldnt give a recommendation. I hope his purchase works well in his system. I'll post details if the Studer900 built unit gives me a boost on the Qutest.. Good luck all and thank you. Dave
  2. Always ways with tools. You can draw around a connector. Drill lots of little holes near, then file out the rough bits. 3mm hss drill and needle files... Rubber grommets for sharp edges... Sorry OT
  3. I copied the description from the link and then search inside aliexpress. Got the exact model coming in the post..
  4. I have heard both sides saying for and against using a linear for the Qutest. I have one on order (Studer) to see. If anything to loose another wall mart. Id love to see if a secondary REG like LDOVRs would improve things more.. 8uV out low noise... Thanks for the heads up, i wasnt going to try with my Qutest from what was said in general... Ill post when it comes Good luck Dave
  5. I thought this interesting, from a piece from Darko talking to Gordon Rankin. Many bits tie in to aspect of the Dual NUC, Buffering and external USB V internal drives. Product aside, a cleaner to reduce CR errors. Something to read. https://darko.audio/2016/05/gordon-rankin-on-why-usb-audio-quality-varies/
  6. Just to add to the oddness, i had two copys of headless tried for ages fiddling with bios.. didnt boot. A copy of the original DL worked ??? On the same USB I burned the original DL file 3 times, the copy got picked up first time. The server original failed, its copy worked. How the original failed ??? Copy was a minute later. Can you easily check the checksum? If a file is corrupted do the checksums count match? Just wondering...
  7. Hi and thanks again for that listen too your Dave in Milton Keynes way back. Headfi quiet room. I have the Qutest off this experience now. My isolation trans was pulsing and getting worse over time i tryed rubber Car panel and PC rubber noise blocker. I even have a mains DC blocker.. Off another issue i bought a mains pass through reader, i was getting the max UK voltage of 251V in Birmingham. I added the Power inspired pre Isolation trans as it outputs 230V Sine. This pulsing has gone. Moving to another part of the national grid might have solved this for you. Most trans seem to be 110 220 230v. I dont know and want an answer if its core saturation, mag flux with higher voltages over 230v causing hum pulsation??? , not sure what others abroad have 240+V as well as UK. Love to know what the cause is just to empower others... SR black suprised me just hate the cost. Glad its fixed, wish i had the PH to play with. Happy new year Dave
  8. +1 Iso regen improves the SQ with my Qutest. A solid DAC at the moment just running off the Switching supply. Powering the Iso regen is my LPS1. Alex and John are cornering the input market with thier leading products. My Qutest sounds simply better with them both cleaning up the signal. Never an issue with recommendations. I hope this helps @Chiler54 Just a nice company..
  9. Makes a good tag line.. "If its about audio, do it in Style.."
  10. Case removal and sbooster helped. Didn't the mac mini Mod by Uptone kill the square wave noise. Removing the fan entirely doesn't have this noise pulse. It ia an audible difference, more than i thought it would be.. Better power helps, the mac mini is Alex's domain.. i use my LPS1 for the iso regen..
  11. Love to see this threads take on the 3.0. As always some positive reviews on this improved spec version of the ipurifier.
  12. The king is dead..Long live the king. Lovely job Chris, cant wait to see what else is in the pipeline. Happy new year to all on A.S. Dave😎
  13. Top off the line are probably the phone makers P+P machines. Those things are monsters placing hundreds of parts per min. Running these is a full time job set ups change overs programming....glad i dont run them anymore. Hats off to you, hand placing a full board is a pain, soldering the lot worse... Good luck as always.. Dave
  14. Probably the wrong place to post this but my balanced isolation transformer was ringing/ pulsing loud and had been getting louder. (Bedroom) i bought some sound deadening wrap (car and PC). It helped a little.... UK voltage 240v i get 251v. I reintroduced my power inspired regenerator as it outputs 230v, pre isolation trans the loud ringing is gone. A DC offset filter did a little. I thought over voltage would just produce heat not ringing as its the same 60hz. Or is this over saturation? Just interested as a non EE, Happy i can hear my music again and keep my iso transformer. I hope you find the right solution Chris.
  15. Happy new year all. To the CA family and those who are important to you. Thank you for a great years worth of reading and learning from you all. Its been a pleasure Best wishes David
