Apple Airplay support since day one

Thanks. Wasn't aware. Does Gustard R26/A26 Shairport connect on the native Apple music app? I don't use Roon.

The only network protocol I really see on that picture is UPnP/DLNA. The other are some kind of Bluetooth protocol?....

Roon needs endpoint that uses upnp anyway?

No Roon hates pretty much hates UPnP. They have their own RAAT protocol

@iFi audio what are the internal technical difference between the v1 and the signature, besides the upmarket Switch mode power supply provided on the latter? And does connecting up an external 10mhz clock time the streamer as well?

Our Pro iDSD Signature includes iPower Elite, but it also features upgraded power supply components to further reduce self-noise. These parts get you audibly tighter bass and darker background.

As for your other question, I'll double-check, but am pretty sure that a streamer would have to have the option to rely on an external clock rather than its own.

Does anybody know what's the output voltage of a 10Mhz clock (sine or square wave) necessary to feed the Gustard R26 or a Audio-GD DAC?

I've built my own master clock using my -118dBc hand picked and tested OCXO.

All parts sourced from AliExpress.

The unit will need about a month for the power supply to break in and for the clock to stabilise, but very pleased with the results.

I've added an IEC inlet filter so the AC is filtered TWICE before going to the linear regulator board. The left board is an AC filter and DC blocker all in one.

All EMI interference is totally shielded from the clock section using copper. I'm also going to shield the DC cable too

That's an awesome effort with some smart design choices (separating stuff, internal copper layering). Keep us updated please!

is the idsd pro bnc wordclock or?

Can you please help?

As per the page 12 of this manual: https://ifi-audio.com/wp-content/uploads/2018/07/Pro_iDSD_Manual.pdf

...it's a clock sync output. Thanks!

The voltage regulator board is not good enough, I used it before in my DIY R2R DAC, it is noise to cause sound not clear and layer enough, then I changed to use Li-ion batteries, sound was darker, cleaner and much more layer. I also use Li-ion rechargeable batteries with LT3045 LDO in my DIY OCXO now.

any information / links on the parts you use?

I used a large case and modular design on purpose so I can easily swap and improve the components

I am using four pieces 18650 Li-ion with LT3045 LDO board at 12V output, the OCXO is same as yours but just -112dBc @ 1hz, you can find many 18650 batteries and LT3045 board from AliExpress

There has standard charger for 4 x 18650 for electric drill use, I am using it to charge four batteries, then unplug the charger when I listen to music, you can use 2P2T switch to connect and disconnect the charger, then let the charger plug keep plug in the clock housing.

Does anybody know what's the output voltage of a 10Mhz clock (sine or square wave) necessary to feed the Gustard R26 or a Audio-GD DAC?

It is not that critical. Usually receiving gears can work with a clock signal of 0.75V to 3.3V. For instance Mutec work in 2V p-p 50/50 duty cycle (square wave)
