Downgrade to FW2014v3 and you gain 32bit support back.
Any source on why using 32bit would be = to an external re-clocking device?
Back when I first ordered a Reference 1 from Kingwa, it only had a S/PDIF input. No other inputs were available. When I asked about adding an optical input (since I was using a MacBook Pro) Kingwa refused, as he didn't want to compromise the sound quality on his top-of-the-line DAC.
Now, however, we have 6 inputs to choose from, all added by demand from customers. I2S has been the last to come, but it is significant not because of itself alone, but because Kingwa's latest USB chip, a 32-bit asynchronous model from VIA, outputs to one of two I2S inputs on the digital board, not to S/PDIF as other chips do. This negates the need for double conversation.
2014v7 was just released. Perhaps it fixed the 32bit support.
There did you find a 2014 v7? I have looked at the AG site but didn’t see it.

I have upgrade/downgraded to FW 9.3 but still can’t select 32 bit in Jriver. Do I need to change the windows driver as well? I have Master 7 btw.
Edit: I found it!
Fun fact: the CM6631A can easily do up to 32/384. Why don’t we enable it? Two reasons: (a) There is no 32-bit music, and never will be.*** (b) There is no 384k PCM audio for sale that we know of. Sure, there’s DSD 2X at 352.8k, but that’s a whole ‘nother discussion.
***There’s a famous napkin-scribble by a famous analog designer floating around out there on the internet somewhere, regarding the noise and precision of analog circuitry necessary for different digital resolutions. I can’t find it at the moment, but it went something like this:
14-15 bits: standard parts and layout
16-17 bits: attention to power supply noise, premium parts, careful layout
18-19 bits: extreme measures taken with low-noise parts, multi-layer boards, and exceptionally fine layout
20-21 bits: God’s domain
Fact is, 24 bits is 144dB dynamic range, which is about the limit of our Stanford analyzers. The best DACs, to date, manage 19.5-20 Equivalent Number of Bits (ENOB), even if they are “24 bit” or “32 bit” spec’d. 32 bits is 192dB dynamic range, which ain’t gonna happen, no way, no how, not even in temperature-controlled circuits sitting within 2 feet of solid lead shielding. Consider that a stun grenade is 170-180dB, and you’ll see how crazy this is.
