Yep, it does oversample. Reportedly Soren tried NOS and wasn't too impressed by the measurements as well as the sound. The DAC has 24bits maximum input word length, but runs at 28bits with the extra 4bit headroom for volume control.

It lives!



Sound extremely promising. With the exception of nasty plops which most likely are caused by Amanero loosing signal on Fs changes.

Great! Glad to have another pirate working on this too. Tomorrow I'm going to switch to an Amanero and use it to provide the ISO 3.3V power. I really want to get a sense as to any gain in using a Reflektor-D to power the ISO 3.3v vs. just powering with the Amanero.

Yea, no plops at all for me, but that's all about the Sonore USB board muting between frequency changes.

Would love to get my hands on a fully built unit sometime. Doesn't this allow you to load custom digital filters? Design might not work well for NOS (you all know I'd still want to try it), but I'd at least like to try a low-ringing/low-oversampling sort of filter option.

Yea, in the not too distant future we'll probably have access to a variety of user loadable filters.

Not only does this DAC has very good tonality, even technicalities are top notch. Very impressed!

Agreed. For a first article, it's sonically very strong. It's getting a lot of attention in the community too - which should result in lots of knowledge on tuning, etc. Very happy with it.

Hi guys, this just caught my attention...sounds promising...I'm planning to get the 02 board and the 12V power supply from Soekris...will I be needing any other accessories?

Thanks

Probably a input board, that gives out I2S. The likes of Amanero or JLsounds boards.
I'm planning the same setup myself.

CCCP legacy lamp switch, lol.

Does the board come with xlr-s?
Looks like your's and MrRoger's have the same xlr connectors.
