Hi, I am new here. Has anyone measured or compared streamers for a Hugo TT2 USB input which I understand is well engineered. I am running an RPi4 with ropieexl out of one of the 4 RPi USB outputs. Got a better power supply for the RPi4 and it does seem to make some difference although I am keeping an open mind whether it is real or I want it to be. For a well engineered DAC would an Allo USBridge family make any difference? Is the RPi4 that noisy that it conspires to reduce sound quality to a well designed DAC input? Am open minded and sceptical at the same time and do not want a religious debate - would be interested in those that tested a TT2 with several USB streamers to let me know their impressions. My speakers are ATC40As. Thank you!
