Thank you, I will
I auditionned at home Vivaldi Dac , Metronome c 8 and a new Gryphone Kalliope feeded from W20. All of them had some advantages over La Fontaine, but the overall presentation of Audio Aero is closest to my preferences : fast, detailed and precise sound but on the musical , rich and warmer side. My former player before I switched to AA was ARC Ref 8 and I liked it a lot during nearly 3 years. Then I decided to go " files" and that's a pity AA is closed - my next upgrade could be La Source.
I will go dsd with Lampi instead.
Congratulations for your sophisticated system.
Wow...that is quite a roster of the best of the best! I have heard the Vivaldi and Metronome but never the Gryphon Kalliope.
I honestly can say if we remove the Zanden transport from my system...and use the Audio Aero La Source as a transport to the Zanden instead, it is not so easy to tell the difference between the Zanden DAC and La Source DAC. The dealer and I spent hours going back and forth, and with the La Source as the transport, it was not easy for either of us to differentiate other than in certain minute elements of the treble. Needless to say, I was very impressed with the La Source and would describe it as you say about your La Fontaine.
One key difference (I believe?) is your La Fontaine can do hires where Zanden is RBCD only.
How does the Kalliope compare with these other SOTA digital sources (including yours)? Most curious!
