One thing I noticed from reviews was that the internal dac is supposed to be a bit rudimentary. Pretty sure that was upgraded in the WIIM Pro Plus Pro but not sure whether its a genuinely decent upgrade or they just wen't from a dac that's fox shit to a dac that's dog shitThat’s feedback that would be helpful because if I build an office set up it will either be my old amp which is a pos or powered speakers. Everyone seems to love them though.
So if you're using an old amp without a separate DAC may be worth going for the fancy version. Think its only about 30 quid more though
