exau2i multi-channel asynchronous usb i2s interface fft plot
using 1khz -80db @ 32bit float/192k
Does this plot indicate that with gear currently available, jitter can effectively be elimiated?
Whether its the jitter, or whatever, these sure are special devices. The EXA U2I with Buffalo dac and the EXA E18 dac I'm using are giving me so much enjoyment I'm amazed they havent received a lot more recognition . The spatial presentation of these things is amazing , soundstaging is stunningly 3D , with placement of instruments so precisely positioned. Sometimes with a good recording you can sense such precise imaging in both depth and width that its like listening to a recording in a completely different way , hard to explain but no way i'm giving these devices up.
I'm using the E18 dac straight off the dac ouputs with the opamps and filters disconnected, tube output, and trying different combinations of the dac outputs ( the dac chip has 8 outputs, 4 per channel ) and the difference between using just one output and 4 in parallel is quite significant, output impedance is obviously the main factor, but I suspect something else is happening here. Its interesting that people comment on the Sabre "sound'- i can tell you there are a number of Sabre "sounds" , but I doubt the differences wouldn't be so audible without the incredible transperancy of the exa I2S devices.
