Hi, I just sold my DirectStrem Dac Snr to fund a speaker upgrade. Amazing with Roon and the Jnr is 90% of the fun of the Senior I thought, for a lot less money. Great value.
But I have just gotten a HiFiBerry Dac+ Pro (Roon Endpoint and Dac, all in one) for a 2nd system, and just modified the power supply to the Dac itself and I’m blown away. I’m going to add a 5V @ 2.4A battery power supply to it next week. If the reviews that adding better linear supplies to the Dac board are to believed, I might be in for an even bigger surprise.
I don’t mention this to really compare with the DSD Jnr because it’s not a fair fight, but might be a really nice progression from the Squeezebox and meet your requirements (streamer and Dac, all in one). It would leave you plenty of spare cash to spend on other areas too. Having said that, the source is super critical and the DirectStream Dacs are other worldly as sources (Bridge II for Roon)
