What could be the real world impact of that increase in distortion at -42 dB? It is similar in magnitude as an unmitigated ESS hump albeit sharper, and last not least even those ESS implementations that had a hump had it from a much lower distortion floor.
 
In the past I've used an Asus Xonar MKII to distribute 8 channels to active XO 3-way speakers + 2 subs. There's lots you can do with 8 exposed output channels.

Even if they essentially do the same thing, I think I'll keep my Okto Dac8 Pro.
 
What is the use of such a box? It is seemingly dongle sized but for 7.1?

A cheap way to experiment with multichannel audio setups (although you need some software to actually decode the source to multichannel PCM) and digital crossover/sub integration. For real use i would prefer multichannel dac like DM7/okto/minidsp or multichannel transport with few dacs on it wihtout all those issues mentoined in the review
 
I wonder if the line in frequency response looks like that because Amir measured the mic in rather than the line in.
No, I definitely made sure it was line in. Even for mic I can't imagine why that kind of filtering would be useful.

To listen to movie and game sound in surround. There used to be 5.1 speaker sets you could get for your computer with analog input which you would hook up to the PC this way. Not sure if they still make them or have switched to USB input.
 
Cubilux makes a nice $35 outboard volume control in a very nice aluminum enclosure, nice feeling large metal knob, with an ALPS pot with a heavy and smooth action. I know it is an ALPS pot because I took the unit apart, because, you know, to check!

i'm bad at maths but i think $599 is a very much larger number than $32...
 
Did you happen to measure the output impedance?
Performance reminds me of the Realtek chips used on PC mainboards, and all of those have 82 ohms output impedance for some reason.
 
Somehow after using the great holoaudio spring 2 dac for 5+ years I am still missing the days of great looking and functional internal sound caards, the likes of Onkyo SE300 PCI-e
 
the category for comparisons here IMO besides cheap-but-good-enough

no stereo-only units

and current drivers for windows.

Personally I value UAC2 for RPi/Linux compatibility, but maybe UAC1 is OK?
 
By combining it with Cavern software that can control ATMOS, you might be able to create a special 4.0.4ch Atmos playback environment on your PC.

It would also be fun to buy a bunch of old surround sound systems from eBay and play around with them. (Fidelity is irrelevant for now.)
