I have the Hermes/Cronus/Rhea and a BBB, but never really liked all the fiddling around with Linux, so the whole DAC has been in 'mothballs' for the last few years. Now, I would like to add a USB input, as that seems like the simplest route to go down. As I understand it, I have a few options: a waveio, a diyinhk module or an Amanero. Is there any way to use what I have, or do I have to buy a new Hermes etc? Sorry, it's been a while since I read up on all this.
If your Hermes is for BBB you need to buy a new one Hermes for Amanero.

Thanks francolargo. Is the Hermes/Amanero all I would need to buy? Does it come with the Amanero board?

I use Foobar2000 as my player. How good is that volume control considered to be?

I see on diyinhk an XMOS board with optional FIFO and which uses xCORE-200. How would that be? Does the XMOS version make much difference apart from maximum sample rate?

As far as I know, none control DAC volume. [Edit:] Perhaps a new volumite with firmware would solve the volume issue. Lately, however, some volume controls included in music player software have improved to the point that on-DAC volume attenuation is no longer superior. You'll have to compare for yourself, since it depends on which player software you are using.
Software based volume control can be the "best" option as it usually runs at 64 bit. The only problem with it is for those who like to play DSD, as most playback softwares do not allow volume control with DSD playback. I use ROON and I sure wish they would incorporate software volume control for DSD (there is a way to do it in ROON using the headroom adjustment feature, but it is convoluted and not very practical). Yes, DSD has to be made multibit (AKA DSD-wide) to control volume, but good playback software can accomplish this transparently now.
The one exception I know of is HQPlayer, which does allow software volume control for DSD.

Looks like the Amanero and Hermes isolator are separate items on the TPA website.

Should be fine, as long as the PC is transmitting all the bits.

I don't (yet) convert PCM to DSD, so perhaps @Barrows can speak to the broader use case comparing XMOS to Amanero. I am messing with a USB board that uses an XMOS XU208 and am quite pleased. It is rated up to PCM768, DSD256 via DoP and DSD512 native. Maybe a more powerful XMOS is available, but to what end? [Sometimes the better I can hear how poorly recordings are mastered, the more distracted I am from the artistry! ]

Stay safe my friends,

Frank

Thanks all. I went for the Amanero in the end - it seemed like the simplest swap from BBB-Hermes to Amanero-Hermes. I'm not sure why I didn't just do that five years ago - it would have saved me days of frustration!

Amanero is connected to I2S isolator properly:
-POWER from Amanero
-FSCLK
-BCLK
-DATA

I2S isolator is connected:
-POWER from Chronus pin 19 gnd & pin 20 3.3V to isolator
-FSCLK from isolator to pin 12 gnd & pin 2 D1 Chronus
-BCLK from isolator to pin 10 gnd & pin 1 DCK IN

Chronus is connected:
-DCK ufl connector to MCLK Amanero?
-D1 left channel output
-D2 right channel output
-One jumper is set to MCK+
-The other jumper is set to J1.1

It's possible can't works because I use NDK SDA but don't installed C1 0.01uF C0G in the Rhea module?

TIA
Felipe

N.B. My player Daphile plays normally without any problem the only is that can't listen music.

I am not sure what you mean by "isolator"? Are you just referring to the stock:

Amanero-Hermes-Cronus stack, connected together by the stock pin headers?

A picture might really help here.

Because you are using a NoDAC, which I am not familiar with, can you give some explanation of what it requires for input? For example, does it just take:

DSDR
DSDL
Bit clock

For input signals?

Again, a couple pictures could help. What DSD rates are you feeding it, and what firmware are you running on the Amanero? And, are you sending DoP or Native DSD from Daphile?

I'm not using Hermes, I'm using diyinhk isolator attached pic of isolator.

noDac not requires clock only needs DATA & FSCLK, the Chronus clock is for Amanero configured the cloks as slave.
