So the problem I have is that my android S10+ has bad firmware for decoding master mqa stuff. I get pops in the audio for anything above 16/44. I can circumvent this with a dedicated audio player but then can’t use Roon. So I decided to look at the 2go.
2 - any decent rechargeable battery of the type used to charge phones - a 2,000 mAh one will give you about 2 hours of play time, but even 10,000 mAh ones ( about 10 hours play time) are not that large and expensive now.
All in all, with the battery, your talking about £100 max. With no battery about £60 with a power supply
Yes, it bulkier than the 2go - but considering that the 2go doesn’t work…
Most of the Roon issues are your own network issues. I use an eero mesh network system which is comparatively inexpensive. I run 8 zones of wireless audio throughout my house and not to mention our computers, phones, iPad’s etc. I can stream Roon to all 8 zones with no issues. I have one of my three eero’s wired to the router, beyond that everything is wireless. It works like a charm. No clicks, no interruptions nada. Get rid of wires and do a mesh wi-fi network. I do get an occasional click once in a blue moon and I noticed that on the rare occasion it happens is when I go from MQA files to standard definition and this is also very rare. You cannot underestimate the power of a strong wireless network. Mt Nucleus is totally wireless (except for the power) and I stream through a Blusesound Node. Remember I can stream all eight zones continuously. without any issues. Good luck and make sure your Roon/Nucleus is updated.
