After several months now of waiting for Firmware patch I have taken the plunge and bought a used Limetree Bridge 11. I have taken my EE8 out, which was fed by Farad Super 3. The Farad is now powering the Limetree.
I am using the PhoenixNet as switch. ND555 connected via Audioquest Vodka. Limetree connected via Audioquest Diamond. BJC router to switch. Limetree connected RCA to BNC digital input 4.
Initial impressions are Wow! The bass is now dark and deep. No high frequency sibliance. Its sounded very smooth and refined. Just how it should be.
So with the Marantz as DAC it sounds excellent especially at reasonably high volume. At lower and higher volumes the Naim DAC ND555 sounds better. And so it should
I now see why so many have added Limetree to NDS and other DACs. Can’t fault it.
Seems you are running ‘Native’ (yellow light) @Dan_M . To try upsampling hold the toggle switch up for 3 seconds and the yellow light will go out. Sampling rate can be changed in the app settings (I prefer 192kHz).
