Did you move from RCA to XLR? A balanced component like the HiFi Rose will output double the voltage on XLR, usually while keeping noise floor the same. So that’s a huge advantage (and +6dB level boost), among other balanced drive advantages (common mode noise rejection). Quality cables definitely matter, but a lot of what you’re hearing there is probably due is the move from RCA to XLR.
Not all components sound better from the XLR outputs / inputs versus RCA. There’s a lot of variables. But it is quite often the case.
