hmm seems dropouts don't coincide with latency spikes.  Might just be dirty power or RFI from other USB?

guys, what exactly do you call "dropouts" in DI's case?

presumably crackling of some sort or dropped samples (actual silence bits)?

 

[kr0gg]

if talking about cracking it is usually fixed by connecting DI to a USB-controller which is not occupied by any other device (that can be checked in the Devices menu of My computer). also, there are cases when setting low playback latency (50-100 ms) helps.
 
talking about dirty PC power - i had this issue (which was pretty unexpected because i thought that my Chieftec 750w PSU is pretty good). switching to a separate power supply made those noises quieter, switching to Audio-gd's PSU for DI made them even more quiet. but anyway when not playing music and turning volume on my amp to the max i can hear noises coming from USB.
never had any dropout issues due to dirty power. i guess it isn't the reason for those.

Mine usually manifest themselves as popping if doing something else CPU/GPU-intensive like Bitcoin mining (DI is the only thing connected to my USB2 controller). More commonly, I get silence for a short amount of time that usually corresponds to the buffer setting.

Has anyone experienced ''clicks'' from the psu affected by room electricity, like air conditioning?

Is there something to worry about?

Yes we have.
 
Yes you have: the PSU of your transport/source is not that good.
 
With my gear: listen to DacMagic, turn on the old CRT TV in the room - music drops out (clicks) for a split second. Do the same while listening to RE-1 - nothing happens, music just continue to play unaffected.
 
For non PSU sag related dropouts with Win PC you might try Fidelizer.

So what does Kingwa mean exactly when he says 'Class A' power supply for the DI?

 

[kr0gg]

it means that it operates in class A - heats a lot, eats more than produces, but gives out really stable voltage, etc.

 

[wushuliu]

Hm, was hoping for a little more detail. I'm aware of how Class A generally works in amplifiers, but not sure how it's being used in the DI power supply.

I'm a bit worried after reading through the last couple of pages. How come people report such significant differences when rolling components such as the hex inverter and such? Honestly it's a bit absurd for me.

Totally agree.
This DI is so well implemented that even upgrading the power supply is barely evident on very resolving systems/headphones.
 
Obviously upsampling is one way of testing sonic differences.
 
I have been using an AD1865 dac with the original mode of the DI, and then with the upsampling turned on - this is definitely a noticeable difference.  The upsampling is highly preferable.  I suppose to some (and me, a few days ago!) it seems absurd to put a upsampled audio streams into a non-oversampling DAC, but at 96khz, the AD1865 seems to have a much better treble!

 

[kr0gg]

well...i myself don't know how people report significant differences when talking about DACs in under $500 range

 

[kr0gg]

dunno about upsampling
at first i liked it a lot, but since getting the PSU i feel that i no longer have the previously experienced harshness in sound, so i switched to non-upsampled mode. it sounds more natural to me now

placebo/bias + not a direct comparison . Price is not necessarily a valid indicator of quality either (and feeds back into the other two ).
