Hello everyone, I have a built DAC with Amanero and 2 Buffalo III SE (ESS 9018) modules. Buffalos work in mono mode. Question - Would it be better to replace Amanero with Amanero/Cronus/Hermes combo? Is Cronus more precise than Amanero alone? Also, does it make sense to upgrade to ESS 9028 or maybe 9038 Buffalo modules (again in mono mode)? Would it bring better sound? If so, what changes to expect with Amanero/Cronus/Hermes? And what with 9028 or 9038 modules? That being said, I am very happy with the sound now. But if it could be better... Thank you in advance!

The ES9028 introduced filtering that significantly improves midrange clarity (easily audible improvement in a good rig). It's backwards compatible with Ivy/Legato (but you need 2 of them to come close/equal the 9038)
The ES9038 added gain stage. It sounds at least as good as dual mono 9028s IMHO. In fact, there is no dual mono option available on the new boards (you have to create custom firmware to do it). The output current is significantly higher - so you must use the Mercury
You'll also need to upgrade the Tridents because of increased power consumption (at least for the 1,2V reg). The new Series Tridents offer an audible improvement (even on your existing 9018). I also highly recommend powering the AVCC and XO with separate clean power supplies rather than both the digital and analog regs running off of the same 5V supply. This makes a substantial difference. You can do the mod to your current rig as well.
The Cronus Hermes does make an improvement too
So if you have the money you will enjoy a substantial improvement

Thanks a lot for your answer!
I think, for the beginning, I will change Legato with Mercury, and Amanero with Amanero/Cronus/Hermes combo.
Which clock frequencies to choose?
Will they both (clock frequencies) reproduce CD, SACD and HD files up to 192 kHz?
Later probably add 9038PRO and Centaurs.
Is it possible to configure 9038PRO boards for dual mono operation?
