I received the Cosmos today. It seems to do what it should.Fingers crossed Ivans new cosmos gizmos will do the trick and put an end to your seemingly endless collection of door stops once and for all Abbey.
Quite an achievement. However, I strongly suspect my ears will once again much prefer my sign-magnitude R2R DAC with 0.007% THD, no DC offset filter and a reconstruction filter that shaves off a little more top frequencies to ensure better time domain behaviour at low sampling rates. Even when listening to orchestra recordings. ;-)Heres some new info on the ES9038 pro dac ,
single channel gives -132db noise , 8 channels in parallel yields -140 db SNR ,but not without 3 op amps per channel as shown in the technical data .
A pristine 24 bit signal can get -144db s/n , 32 bit can get a theoretical -190db noise level , next to impossible to realise those figures in the real world though . Obviously the Cosmos dac wants at least -130db noise just to keep up with the ADC performance , then the APU might filter out another 20 db or more over a specific frequency range .Its not far off the best Audio Precision specs for the equivalent of pocket change .
A recording system with 130db dynamic range and 180khz+ bandwidth isnt required for rock n roll thats for sure , but it might preserve the scale of an orchestra going from quiet to loud intact , from a whisper to a roar .
Yes. John Mulcahy recommended it over ASIO4ALL that has some issues also with 384k.Was that the Flexaudio Asio driver you used Abbey?
Don't know about it...The Comtrue driver seems to have a few issues , specifically running at 384khz with REW .
I hope so.Ivan is in close contact with the chipset manufacturer and its my guess the issues will be ironed out soon .
I noticed he communicates on discord, but when I found out it was some kind of Facebook/Twitter wannabe that propagates malwares I fled courageously.He has a discord page here relating to cosmos ADC in case of any questions ,
Good question. SSL certs used to be expensive but if you're a non-profit you can use Let's Encrypt. Certs are only good for 3 months but you just install the auto-update script and never have to worry about it again. That leaves domain registration and hosting. Domain registration comes out to about $20 / year. For hosting, I'm pretty sure there are some free options but they're probably limited to static pages. Then you have proper copyright control over your content. If you want a forum, ZenForo (the forum software used by this site) is not really that expensive. PHP hosting is probably $15 / mo. If you're selling a product then it's tax deductible (but you would then have to buy a proper cert).Why can't people put their pages on a website?
I took the "B" bundle, as it was the only one available.Abbey, which cosmos 'bundle" did you buy?
I'm not so sure but it looks like it, although there may be a difference in THD (as they may be difficult to discriminate from each other)Do you know if the only difference is on the noisefloor?
I haven't seen a price for the "C" version, but I doubt it's significantly cheaper...I'm asking because I'm trying to be a bit cheap and get "bundle 1" which hopefully will still be OK for most of the tasks.
