It can't be that hard when looking into TLE2426 datasheets... Now can it? Or.. Had you even bothered to look at it? 3 Pins; IN, OUT, COMMON. Output (aka your desired ground level) is half the voltage level of IN and COMMON. So you want to halve the DC + and - to get the ground level? > Simply...

  But doesnt this asynchronous SMSL M8 already have its own (2) clocks in it? Now the same digital signal is just routed through another device, then back to M8, which still has its (not that good?) powersupply. What about the M8's coaxial input + digital to analg conversation? The M8 power...

    Could you enlighten me/us how routing the data through another device in the signal-chain can make it sound better? How do you output it from Gustard for example? Optical? What is the purpose of that / Why does it differ from feeding USB right into M8?

  But your point on that USB box/cable changing sound in those SMSL products still doesnt make point, even after doing your tests again. Since the SMSL products does not use the USB power line, which your "box" (and/or cable) is "enhanching"/filtering power noise. It only uses the digital data...

  But the SMSL M8 uses external +9V power supply, not USB's +5V. SMSL VA2 uses external +12V, not USB's +5V. Not using the USB +5V supply, so only way that "USB box" may change the sound is by wirelessly sending positive energy to the SMSL products. Unless it is filtering the digital data of...

  Just had to google what the heck is "Elfidelity USB purifier" and how in the world could it change the sound in the digital transfer of USB. Seems its just a box of bunch of capacitors added for USB's 5V power section? Besides, Doesnt SMSL products use external power supplies, so maybe the...

  Very interesting thoughts. Thanks for sharing!

Guys when you are soldering different capacitors on single op-amps for its power connectors, and judging how they change sound to your liking or disliking... Have you ever thought that there most likely will already be factory soldered capacitors on the pcb of the device youre using, for the...

  DAC SNR 98db vs112 Coupling caps vs no coupling caps (reducing sound coloring etc. by the caps on the signal way) Voltage regulator: unknown(?) vs LT1763 16 bit vs 24 bit ES9023 much lower THD, much better channel separation 70 vs 100 I have SMSL M8 with ES9018 and it sounds just great. The...

When listening to music, does it interfere with satellite tv broadcasts?

Does the zeros look more round and the 1's more sharper with that cable?

  If you tried the headphones straight from the phones audio output, maybe it is due the difference in the phones output impedance? From my own personal listening experience the output impedance has much greater impact on sound than DAC chip or OP amp itself. This could be found out, if you had...

  It means excluding VAT (tax), just as it says. So it will be expensiver for customer than that. Added to shopping cart it says Grand Total Inc VAT £189.00, which is 260€ / $290 Edit: Seems someone already explained it, wasnt reading the last page of thread yet.   Come on now, if it was...

Keep your output volume at 99% and lower your input volume to desired amount. Keep the signal with -1dB or less in RMAA.

What changes did you do for those new results, as now IMD and THD are greater for ELE DAC than previously? Have you also changed to 16bit/44.1k through windows playback/record devices? Are you using Xonar DG line-in to record? If you want to try, you could test the line-in of your mobo's...
