...Upgrade-itis. My present day DAC (Caiman SEG+ Dorado PS) appears more than adequate.

However, I'm keen on the Gustard. One problem is that the Caiman has 2 Toslink inputs and the Gustard only one. I really need two. However my AUDIOPHONICS I-Sabre V3 DAC ES9023 TCXO Raspberry Pi 2.0 A+ B+ / I2S - has, as you can see an I2S output and the Gustard an IS2-H (IIS-H). Are the two compatible, and, would a normal HDMI cable be sufficient to link the two?

All my system is 'unbalanced'.

The Audiophonics gear is largely redundant as I view the Rpi+ Allo system slightly superior (see: https://theartofsound.net/forum/show...748#post900748)

I'm largely ignorant of all the basic methods of inter-connects (I use RCA/Toslink/Optical - but not USB (well I do in my other system - but I'll ignore this at present). I know nothing about AES for example, (but it seems expensive!)

Any advice gratefully received.


Thanks.
