I don't know...
I just ordered a DI V3 (with TCXO) and hooked it up. I just use the coax input on the DI, no usb connection, so I thought the firmware version was irrelevant.
I repeat: this thing sounds fantastic!
I would be interested to see if you can connect using the USB with the EDO software in your SBT, I dont think I have seen anybody in the forums that has managed that yet, if there is I would love to know how you do it. As I have said previously I am using the green Firmware (#5) from the shipped pack, to run the SBT via USB can run the 192Khz files but only in adaptive mode. You wont be able to run above 96Khz using SPDIF.
And that is why I gave up on the DI-V3 and went with Plastic Fantastic (a Micromega MYDAC) - I knew it would work perfectly with EDO. I really hope they get the EDO issues worked out because it is a good looking product...
I would, but I can't. My very few 192 kHz files are on a usb hard drive that occupies the only usb connection on the SBT. And, though I have EDO, my SBT does not play 192 on coax either. I don't mind that very much, because the Ref 7 doesn't go higher dan 24/96 anyway (it plays 192, but downsamples tot 96). With the Ref 7 / DI V3 combination I am astounded how good 16/44,1 WAV files can be, let alone 24/96 FLAC.
So do I. I have green firware by default and received green as second firmware.
Is the black asynch and green adaptative?
If some here tried both, could you please report what real differences you found about sound signature?
You have to ask for it when you place the order. You'll have the I2S output at the back of the DI, which you can use to connect the DI to your I2S input at the back of a Ref7.1 or something like that.
Apparently, you can also have I2S input for the DI.
