Sounds like you have some nice kit to play with
I am currently using Cyrus equipment, I suppose the value of the transport + DAC + power supplies is in the region of 5000 Euros. The DAC is the DAC X Signature, I don't know if it supports DSD or not:
http://www.cyrusaudio.com/product/pre-amplifiers/dac-x-signature-1Pardon my ignorance, but what is the advantage of converting to DSD, or any other format, for that matter? I have always thought that you can't get any more information than there is to start with. In other words, how can you get better than CD quality from the original CD?
Just to clarify what I have been doing with the iPad:
1. When I want to access my (few) music files which currently reside on my PC: launch JRiver on the PC & enable the media server function. Launch the JRemote app on the iPad & select my amp (not the iPad) as the player. In JRemote I can see the media on the PC, so I then select what I want to listen to & bingo, the audio goes through my hifi system.
2. If I want to listen to Qobuz, JRiver is not used. I launch the Qobuz app in the iPad, select the amp as the player as before. Then sign in & choose something to listen to, which then plays through the hifi, not the iPad.
I'm guessing that in each case the music routes through the iPad, then wirelessly to the router, then down the Ethernet cable to the amp, which has a network connection.
EDIT: I think I misled you slightly: although my preferred DAC is the Cyrus, it does not have a network input, so I'm currently networking through a Pioneer AVR which has ESS Sabre DACS. I've just tried playing a DSD file through this AVR, but it will not play, so I guess this one does not support those files.
I have a Cyrus streamer on the way, this will allow me to network through the Cyrus DAC, so will give it another try when the streamer arrives...
