    Cayin RU6: R-2R USB Dongle DAC with Head-Amp

    Use it on 76 instead, or one of the volumes right before the skip happens (64, 76, 88, 100). Trust me, you will get much less noise this way, and overall cleaner sound.

    Cayin RU6: R-2R USB Dongle DAC with Head-Amp

    If you tried the test I described, lowering volume of the source and increasing it on the RU6 and then checking the noise levels you would know right away what I am talking about, because it is very apparent. So either my unit is defective (which I doubt) or no one here really tried to...

    Cayin RU6: R-2R USB Dongle DAC with Head-Amp

    Thanks a lot for this very informative answer. I do not want to sound very stubborn but one thing is still unclear. As you quoted "the background noise of the R-2R ladder DAC circuit will increase as you turn up the volume", which makes perfect sense, but the noise I am talking about is not...

    Cayin RU6: R-2R USB Dongle DAC with Head-Amp

    First of all, thank you for responding. I am not doing this, of course. It was just to demonstrate issue that is difficult to notice without reducing volume (but is still there at max volume during very very quiet parts of music). I am not experience noise during switching, what I said is that...

    Cayin RU6: R-2R USB Dongle DAC with Head-Amp

    Well, did you try what I suggested? lower the source volume almost to 0 and increase it on the DAC, and pay attention to what happens to noise during volume steps. I feel like you are the one disregarding my claims without checking it. If I hear any counter arguments or counter evidence to what...

    Cayin RU6: R-2R USB Dongle DAC with Head-Amp

    Multiple things, LG v35 with UAPP, Ibasso DX160, PC, Tablet.. It does not matter, the result is always the same, because as I said, it is not a static I believe it is just imperfection of the DAC.

    Cayin RU6: R-2R USB Dongle DAC with Head-Amp

    It is not static, it is a weird noise during the very quiet sounds (but not during the silence). It can only be noticed during very quiet parts of high dynamic range music. But for the demonstration you can reduce the source volume a lot(almost to 0), then increase cayins volume and check the...

    That does not explain increased noise only at every tenth/twelveth step at all. If every step was analog at the same stage of the circuit, SNR would not fluctuate like that.

    Cayin RU6: R-2R USB Dongle DAC with Head-Amp

    I have a theory about the volume control, please correct me if there is any information which disproves this. The resistor volume control has only 8 steps (probably by having 3 resistors with different combinations) and substeps between them change volume only digitally (at the dac level or...

    Cayin RU6: R-2R USB Dongle DAC with Head-Amp

    I have a big issue with Cayin RU6's noise floor. I am not talking about the typical hiss, but rather weird almost glitchy noise during very quite parts of very high dynamic range music. This noise increases every time volume makes that 'glitchy' step(for example from 40 to 41). This means that...

    I am a huge radiohead fan but everything after the bends is mastered horribly, they qualify as one of the worst offenders of loudness war. Anyway, you should never have classical and non-classical songs in the same queue, even decently mastered mainstream music will be a lot louder than...

    I have both, Ananda and Elegia. They are two very different headphones therefore they complement each other very well. If you want more bass than Elegias then Ananda is not for you. Actually elegia is much punchier than Ananda, with much more defined imaging with clearer and more localized dense...

    Massdrop x Alex Cavalli Tube Hybrid Amp (CTH) - Dropping Monday

    Thanks a lot. I will definitely give it a try once I get over the honeymoon period with the Tung-Sol tube (it arrives next week). Will the difference be significant between different 12at7 tubes? For example between the tube you recommended and Tung-Sol 12at7.

    Massdrop x Alex Cavalli Tube Hybrid Amp (CTH) - Dropping Monday

    Hi, new CTH user here. I am planning to roll Tung sol 12AT7 with this adapter. Can anybody tell me if there is a reason for me to be concerned about frying the circuit? I know it is only recommended to roll 6922 but I am not sure how unsafe it is to not follow the recommendation.

    Does anyone here have any experience with any third party pads? I remember someone mentioned zmf oval pads, but I am not very sure it will fit. (Of course, I plan to attach the ring of ananda's old pads to the third party pads)
