    Topping D90 Balanced USB DAC Review

    Try another source on the same input to verify it`s DAC related. If so, and you use a PC check that your program is using D90 for sound.

    Intona USB 3.0 Isolator Review

    Sounds like USB noise. I had the same issue. When running PC on battery it disappeared. Lack of proper galvanic isolation in the DAC combined with a faulty power supplt was the case. Intona made the issue go away 100%. No need for battery opation. Tried other cheaper isolaters from Ifi first and...

    Intona USB 3.0 Isolator Review

    Intona is not cheap, but it works. I had ground loop issues and bought an IFI USB 3.0 which should brak the ground loop. Didn`t work. Embraced the suck and bought the Intona.

    Topping D90 Balanced USB DAC Review

    I have experimented a bit with different filters on other DAC’s than Topping though. The difference between minimum phase and linear phase filters seems clearly audible. Much more difficult to distinguish one linear filter from another linear phase filter or one minimum phase filter from...

    Topping D90 Balanced USB DAC Review

    Well, all DACs with filters, sound ever so slightly different. I haven’t experimented myself, but from what I read some prefer one Topping D90 filter and some prefer another. If the filters sound 100% identical, only one filter would be needed! I guess logically speaking one filter could...

    Topping D90 Balanced USB DAC Review

    USB noise sucks. I’ve tried different fixes. Ferrites, power conditioners and the Ifi 3.0. The Ifi helped, but just a tiny bit. Could stil hear USB noise from listening position. The noise varied from time to time in strengt but was unacceptable. Went for the Intona and all ground noise...

    Topping D90 Balanced USB DAC Review

    My D90 turns off automatcally a couple of minutes after turning off the computer. Displays «See You» last seconds before turning off. My D90 is in preamp mode and I haven’t done any adjustments upon taking it out of the box.

    High Performance PC Server Interfaces (Async USB)

    Hello. yes I am still using the Berkeley. I`ve tested The HiFace, a cheap solution. It gave OK results, nothing more. A solution only if you don`t have USB. I`ve wanted to use only the USB and lose the Berkeley. Can`t play DSD with the Berkeley. Not a big Issue, but if I can do with less...

    Intona USB 3.0 Isolator Review

    Thought I'd share my personal experience:). I had a serious grounding issue with my old Asus PC. Heavily distorted sound when streaming from the USB output into an Accuphase DAC 40. When connecting headphones directly to the sound output of the PC I could hear the same issue. I tried an IFI...

    Nord Three SE 1ET400A Dual Mono Stereo Amp Review

    @amirm. Thank you for yet another interesting review. You write that the dual mono probably will last a lot longer than the stereo version. Could you elaborate a bit on this please? what lifespan do you think we can expect from these amps?

    Review and Measurements of PS Audio PerfectWave DirectStream DAC

    I think, nontransparency is part of the business model for PS audio and many other manufacturerers. It sounds different, costs much money, therefore it's better. Had a PS audio HCA-2 power amp, back in the day. Reviewers stated: "Finally a non tube design that sounds like tubes". Well, It had an...

    Review and Measurements of PS Audio PerfectWave DirectStream DAC

    Thank you Amir, kind of expected poor results but this was far worse than expected, and kudos to the owner sending it in. Would really like to see tests of other costly DACs from DCS, Bricasti, Berkeley and so on. But I guess the upside for an owner of an expensive DAC is negligible and the...

    Review and Measurements of Wireworld Starlight 7 USB Cable

    An inspiring review. Didn’t think this could make any difference. Went into my cable storage and pulled out my Gemini USB cable and installed it into my system. Never used it before. :).
