  1. @992Sam, the DG-58 is now replaced with the DG-68, the new Accuphase model has some very worthwhile improvements, sometimes, it's not so drastic. For instance the 2020 pre-amps have improvement to the S/N some 5db or more, that's considerable on paper, would you hear this..some would suppose :) The Accuphase product is designed for the long term, 15-20 years about the minimum expectation, my vintage E-205 (bought 1988) integrated amp still works. Don't feel that the new model is a must have I need to point out, once an Accuphase model is no longer available from the factory, that'
  2. The commercial reality conflicts with your intentions. I agree that an SMPS with low leakage output with respect to noise is about but not easy to find. There's a brand from Japan, name escapes me for now, but not available for the hobbyist from the likes of Mouser or simialr, inaddition to that nonsense of exclusive distribution to the one country. What is a cheap linear supply? That statement is a bit open ended, but let's find some common ground. It all depends on the load device in question. For instance the EtherRegen or the range of LPS from Uptone. The power supp
  3. many, many others have heard a difference of what an LPS can do. It depends if a SMPS is part of the AC network, the same as the audio, then there will be problems. Inside commercial network switches are also SMPS, defeating purposes somewhat.
  4. Thanks for the advice as it mirrors many who have an EtherRegen fitted. There's a few instances where the Etheregen and Lumin have dropped connections now again, but looks like these are largely solved. The use of the linear supply would benefit components outside the chain, as noise can find a path where it likes and ends up in what can be heard. I don't think noise can be eliminated, but at least add a component to be 'minimal impact' and that ends up with a good LPS as a start.
  5. Well, if copper is converted to optical and then back again to copper there's two power supplies that can be removed. Unless the connection is more than 100m, then the extra conversion allows more noise at either end of the optical chain. The X1 is the only Lumin with optical, so it avoids the last conversion externally and is treated inside the X1, fair enough. I'm not willing to spend $$,$$$ to perhaps improve the sound which I may not audibly pick-up. So for now, the U1 is doing a great job with copper, saving for an Etheregen to add in the future.
  6. Change to a different player? I don't hear clicks with Jriver, Roon, Audirvana, but on DSD , HQPlayer can struggle. The change in volume is instantaneous, maybe something in the DAC that it needs the don't mute function to be designed properly. For example, Sony TA-ZH1ES hp amp mutes the relay at every track change, sends me nuts with Jriver and Audirvana, but the Accuphase DAC-50 and DC-950 are fine with Jriver and Roon, but plays up with Audirvana. The real problem is when the clicks are heard at every start to the track.
  7. Roon can network input to a streamer, Kodi cannot. KODI cannot play to multiple devices over the network either. After trying to find fruitless what sample rate Kodi can play, will assume it can't play DSD let alone SRC. You tube opinions are rife with just that, opinions to entice clicks, hence revenue.
  8. Either the Regen or the ifi Micro USB 3.0. Have good results with the latter, it's a good cleaner of USB crud. Needs a good 9V linear power supply to get the best out of it. Can then use existing cable from the Micro USB3.0 to the DAC and a new cable to feed the micro.
  9. I used the regular windows format command and didn't work, so tried with create partition with Bootice and from then on, the ripping worked. The USB stick wasn't labelled with any certainty of working hahahaha 😀
  10. I gave up on Sonore and Java some time ago with a new Win10 pc. For ripping SACD, I use the command line with admin privileges. When you changed to a different USB stick, looks like the original was not partitioned. Even though the files and folder are the same , the partition needs to be active. Smaller the USB the better like and old 1GB or less. "Prepare a blank USB Stick, use Bootice to create a new MBR, format the drive to FAT32.." Hope this helps. Here's the batch file I use, called SACD-Ripper2.bat created in Notepad. Run it from the desktop, and
  11. Extreme upsampling contains processing noise which is mistaken for ‘clarity’. Since the OP is using USB to the DAC, this further exacerbates the issue, unless there’s a USB fixer in the chain that minimises noise from the host. If you listen long enough to upsampling, the sound becomes tedious to the point of irritating, reverting then to the standard sample rate of the source then sounds ‘as intended’. IMHO.
  12. Lera Lynn - On My Own Touted as a career changing album, well, that's pretty close. Lera's pitch is very similar to Sara Bareilles, that's about it for commonality, very thoughtful and haunting album., one of those that draw you in. Production is spot on., very highly recommended. One of those albums when ends is far too sudden. DR10 (measured by Roon) bodes well, great image and depth across the sound stage, these guys did well with that.
  13. The 0V from the PSU is at earth potential. The -ve rails cannot be grounded since it will cause a short circuit. The 0V in a computer power supply is often earthed, the two PC's I have are out of the box. Grounding one end to earth of the 0V doesn't guarantee that it will be the same at the load end, since noise pickup will create potential differences. By using a balanced supply and routing the 0V can effective noise cancellation occur.
  14. Here's a low noise design, but it's only a guide to illustrate the purpose, the voltages and currents are incorrect for ATX use. 30,000uF is substantial for power delivery, must say, not much would get through that. When the load is connected across +VA and -VA, the voltage is 26V (not zero). +13V is measured at the + and PGND1 and -13V also at PGND1. PGND1 is connected further back at the transformer to earth (ground) PE conductor (AC 12V C.T.) Depending on cable lengths, say 300mm or more, the load side PGND1 needs a separate wire back to the transformer earth po
