You mean MQA decoding when connected via USB i assume? I do not play MQA with my computer attached via USB very often but when i do it worked perfectly. I played from Tidal for using the Roon end point on my computer and both worked great.
However, there are definitely problems with stability for anything that is under the "App" input (i.e. not only Ethernet but also SD card or USB hard disk). To me only Ethernet is really important. And indeed version 2.01 does not seem to have any improvements in that respect. I love how the Pro iDSD sounds. But one of the reasons that i was attracted to it is that it included streaming support over network. To me it is critical that the issues with the App input are solved.
Also, as others have suggested here, it would be a big thing to make the Pro iDSD Roon ready.
Right now i have to either wait until software updates for the Pro iDSD, have to buy a network bridge like SMS 200 Ultra, or look for a different product.
Hello, not supporting Roon Raat protocol is something to have in consideration.
To pair the Pro iDSD with good results with Roon and considering the SMS 200 Ultra also buy the SPS 500 Power supply and the silver cable for the power supply, and you can obtain good results, do not forget a good USB cable as at this level makes obvious changes in the sound.
But then if you consider the added cost to have Roon to work well, and I made all this hardware aquisitions, we start to consider the added investiment we made to make Roon work with the Pro iDSD could be very well spent to another better DAC with direct roon support, as the cost of adding Roon with decent streaming quality compared to the network direct connection is similiar to the price of the Pro iDSD, so the DAC duplicates easly the price to be used fully with Roon.
A simple move from ifi to support Roon could result in not spending an aditional 3000 or more euros, and have the same or better sound simply investing in a good network cable.
So if you are considering Roon for your music collection and have the funds to buy aditional hardware to get the Pró iDSD working well you have to take this into account, the SMS 200 Ultra is better than any computer I used as an end point, computers are noisy by nature. Otherwise search for another DAC because Roon only supports the Pro iDSD on Airplay, the same with Denon and Marantz Recievers.
I still have hope iFi implements RAAT protocol, to be sincere I like MQA but easly echange it for RAAT without thinking twice. For me is too late to make a decision on another DAC now, but you need to evaluate this before buying.
Audirvana is full of bugs, slow, and after using roon for an year as a lifetime subscriber going back to audirvana is not an option anymore, I could say the same for other software packages. The Muso APP is something horrible and desappointing.
But the Pro iDSD is an amazing DAC, but needs better and faster firmware devlopment to realy shine, the latest beta 2.01 is pretty stable but nor there yet.
