Good. Thank you.
Better when said.

1.4 uses ESS converters. There are no changes in performance and I don't think that tech specs will differ significantly, if at all.

Hi to everyone!

See the ADI-2 DAC FS was affected by the change of AKM to ESS chips.
See also on Thomann that there were a 1.4 revision of the AIO Pro with ESS ADC/DAC, as they posted a product picture of the PCB.
On the RME site it's still quoted that those use the ADI-2 Pro Converter AKM chips.

Is there a newest HDSPe AIO Pro revision?
Does the performance change between them?
Are there any new measurements of the ESS version?

Also, if I may ask, is the headphone output Class A,AB and Transistor or IC based?

Many Thanks in advance,
Federico
