Chord Qutest + MScaler

I improved the SQ of Qutest significantly when I changed BNC digital socket to Audio Note silver RCA and started using NBS Signature cable. I also removed the original brass RCA output socket from Cary CD player (used as transport). 
Thank a lot to @zipost suggested me to do it! All these BNC digital socket made of brass and ruin SPDIF signal as well as RCA brass sockets.

I have Altec 604E speakers with Werner Jagusch crossover (upgraded with Duelund and Jupiter capacitors) and 300B amplifier with Hashimoto H30 output transformers.

Have anyone tried Sbooster with Qutest?
I have a horrible experience with 2qute and a MCRU power supply.
The sound was so odd and ringing like a glass. I sold the MCRU power supply on EBay but I lost 70% the of prise.
