also im awaiting a black lion 2x2 revolution interface which is usb powered (since i wanna replace my aune x8 because of the noise issue, it gets triggered with hqplayer quite often), it will be interesting to test the supercap
of the dac or of the ground filter device? pretty sure there are theoretical improvements after the device if you look at specific things (noise on datalines after common chokes for example), also the supercap should act kind of as a mild noise filter, not sure about the dac output tho...But can you measure a difference on the output?
i finally wanna get USB "right" at an affordable price, tho i still see myself end up one of these audiophile pcie cards maybe in the end just to see if there is more headroom..Sounds like you really working on it.
maybe in the higher (inaudible) frequencys but most reviewers dont show that...I'm with you that I don't think steady state tests would show much on the dac output.
My offer stands if someone wanna measure thisNull testing with something like deltawave would be pretty conclusive tho. Even tiny changes in the null ratio would show it's working.
yea i have some spare, since its a prototype and you are located in germany i can offer to send one for 20Euro including shipping if you leave a reviewHi ghoostknight. I just found out about idefender and googled for a diy version since it seemed a little expensive. Then k stumbled upon your posts here.
Do you sell your version?
Do you have schematics for me?Built my own USB isolator + filter Connector several years ago, it was for my iFi iDSD Nano DAC. Learned a lot at that time, inspired by the iFi USB Cable and another one.
Worked well.
yea definitely, all about USB seems to be a compromise, but you are right i agree with the general consent to keep cables as short as possible, tho for my setup it has to be 2m... i dont wanna park my hifi directly beside my PC...Use shorter USB cables wherever you can: they're a compromise.
i actually also still wanna build a power distrubution unit ... i already have the right EMI filter for it which im already using in a non-ideal plastic box, also this made a noticable difference EMI/RFI wise... also ferrite beads help alot, you can specially place 5-10 of them on the power cable of your PC for example... it really helpsHa, you found it! A behemoth of a thread but I was also learning as I went along. Good times!
