Hi Melm,
I have assembled a Raspberry PI4B based Streamer/Dac composed of the following IAN CANADA boards:
1. PurePi II (Ultracapacitor Power Supply + LifePo049
2. Raspberry PI4B
3. ShieldPi Pro
4. Flagship Re-Clocker FifoPi Q7 II with the new FemtoMck XO clocks
5. ES9038Q2M Dual Mono II DAC Hat
6. MonitorPi Pro
After several tests I found the correct settings but I think further refinements are necessary. What I am listening to both with DSD files (played in direct mode up to 128), both with DXD files and with Flac Music both from files and in HiRes Qobuz seems to me to have obtained a high degree of acoustic quality. Certainly in my system there is an excellent analog chain (SME TT - SME Arm - Lyra Titan - Benz Micro LP etc.) which obviously sounds better but as far as digital is concerned I am extremely satisfied. Surely the next upgrade will be to insert a IAN CANADA UcConditioner MkII/Pro 3.3V to further improve the power supply of Re-Clocker and ES9038 DAC. What I learned the power supply is fundamental. And anyway thanks for your experience. Kind regards.
