I'm setting up my home, well flat-office, and starting from scratch having recently lost my portable dac/amp while travelling. What would work well with an iMac? I'm looking to spend less than £300 ish as i'm on a small budget due to new circumstances but I can't live without my music. I prefer using Tidal for streaming and don't mind a bit of MQA. I've used an iFi before - the now lost nano BL) but I'm open to suggestions. Doesn't have to be portable as I now pretty much office based. Thanks.
