Very very interesting thread. Thanks a lot ValentinHogea
The most interesting of the list seems to be the RWA Audeze Edition, but it's 16/48 kHz limitation from USB is not very convenient since it need a USB-to-SPDIF adapter to get 24/192 kHz. I sent a mail to RWA to see if they have a new "full 24/192 kHz version" planned... Otherwise the RWA Corvina + a portable DAC may do the trick, but this becomes a 3 pieces solution (Source + dac + amp)
YES - we are working on an upgrade to our Isabellina Pro dac that will allow for up to 24/192k async mode USB (including 44.1, 48, 88.2, 96, 176.4, and 192), converted directly to I2S that will feed out galvanic isolator chip (that we currently use) and will feed our NOS and High Res dac chips.
No driver will be required for Mac, but a driver will be needed for Windows (which we will have on our website for download when it is ready).
This will become available for ALL Red Wine Audio products that feature our Isabellina Pro dac, and upgrades will be available for customers as well who do not have this. I estimate it will be ready sometime next month.
Thanks for all your posts - this is a great thread!
