First and foremost, best wishes with the surgery and for a speedy recovery. Especially if this is a temporary stopgap during your recovery I’d consider an Audioquest Dragonfly Red and just use that plugged into your phone or tablet. I drove my Hifiman HE400SE ‘phones with them quite successfully and your Sundaras seem even a little easier to drive. Plus, if you ever want to take your music on the go in the future the Dragonfly makes a great portable travel companion. Just a thought, and best of luck with everything!
Combo Streamer/Headphone Amp
I'm having shoulder replacement surgery in a few weeks so I'll be laid up without use of my right arm for sometime afterwards. Pretty much means spinning vinyl is off the table. And I will be pretty much immobile in a recliner for the first couple weeks/ So, I thought this would be a good time to catch up on my headphone listening. I have some OK Bluetooth (Bluetooth SQ limitations noted) Sennheisers, but I really want to use my HiFiMan Sundaras. What would make it great is if I could find a single box streamer/headphone amp combo using some relatively common app like BluOs. The Blusound Node looks like a candidate, but I'm not sure it has enough of a headphone amp to drive my Sundaras. Thoughts? Alternatives?
