Hi all,
I love the obsession. I have put together a fabulous system, prioritizing digital through Qobuz and roon, and during this process I’ve had a few conversations with engineers from fancy audio companies and the like…
My digital stream is comprised of the following: Mac mini and wifi bridge (on their own circuit) → ethernet to a netgear with (on a dedicated circuit and powered by an sbooster linear power supply) → high quality ethernet cables from QSA → Nagra Streamer (on a AGY power conditioner hooked up to a dedicated circuit) → SoulNote D1 DAC → Decware 300B Amp → Pure Audio Project Duet 15 Horns.
I’ve paid special attention to quelling EMI, RFI, and Mechanical noise.
I hear a difference between Qobuz Connect and Roon through this digital chain. After my conversations with several engineers, I attribute this to the influence of each component and wire that leads to the Nagra Streamer. Each metallurgical and mechanical connection influences the sound, since it is influencing the electrical signal. It’s like a book with the same text, but with thick patina’d paper, vs a paperback. The information is the same, but the material (electrical signal) is different.
And since this tiny electrical signal, weather it be encoding the music digitally or in analogue, meets the power amplification from the electrical mains of your building, all of it has an influence on the sound.
SO… I attribute the difference between Qobuz Connect and Qobuz via Roon, to everything within my digital chain that Roon requires.
Qobuz Connect takes all of the same “bit perfect” music and brings this to my DAC in my Nagra Streamer. That is there the electrical influence to the signal begins. Nagra does it pretty purely in their streamer.
Qobuz via Roon takes the same “bit perfect” music and detaches a lot of the processing from my main component stack, minimizing noise from this source. But it is still dependent on all the components from my Roon Core and the Nagra Streamer.
AND, since I love the Roon interface so much, my question is how do I get my Roon chain to sound more like the shorter Qobuz Connect sound.
