Guys, would you mind verifying with me a couple of things about R2R and its (normal?) specs? Yes, I love the form factor, I/O, sound an powaaaa, but I need to verify a few observations I need to verify with you, guys.
My obsevations:
-
Waking PC from sleep - sometimes the videos on YT will not load and sound will not work in general -- powering off and on is required;
-
Good old popping when you turn on/off, switch media (BUT NOT ALWAYS, sometimes it does, sometimes it does not), especially when I switch to speakers and have higher volume (pre-amp mode), input is USB;
-
After switching gain (L>H, H>L) and raising volume from zero, then on the first raise between 7-11 o'clock it makes crackling (like when you block radio antenna) noises in the headphones/speakers, lowering and raising again is ok and there is no more crackling, unless I switch gain and start raising from 0;
-
Analog-ish (white/pink noise style) noise raising its intensity with the raising volume (noticeable especially after 1 o'clock);
-
Transformer buzzing (the level you can hear when it is quieter around) which you can hear up to 70-80 cm (80cm =~ 2 feet 7½ inches) away from the front panel of the device (on a desk);
-
Starting at ~2 o'clock to maximum volume if you feed any signal (so let's say you have a song with an extremely quiet passage or you just pause the song)
you get a weird "sine-wave" sounding noise, here is the
sample)
All these were tested (if possible) with no source, no output when testing symptoms on headphones; especially to mitigate any common-mode noises. Everything testing on multiple power sockets with no other devices plugged in and on one socket on a completely independent power circuit.
If you find a time to get through these, let me know, if you experience similar things or if there is anything which you don't experience.
