Actually I did audition a more expensive Cambridge audio unit but the wiim sounded better so I kept it. Like I said, I trust my ears first and foremost.
It’s fine to trust your ears, but your Wiim is far beneath your system and although you may like the sound now you won’t know how much better it can be until you try something better, and there is far, far better out there. I’d suggest trying a better DAC with the Wiim first to start to hear what’s possible. For perspective, if I had your amp/speakers I’d have a streamer and DAC totaling in the $10k range so they’d be more inline with the sound/quality of your other components. In audio, the chain is only as strong as the weakest link and everything matters, and in your system the Wiim is a glaring weak link and is significantly holding back the performance of your system whether you recognize it or not. But I’ve only been at this for 40+ years so what the hell do I know? I’m just trying to help you here and pretty sure others will largely echo what I’m saying, but do with this what you will.
