samsung phone charger PS, yes it was connected all time as it should. stand by and power on was managed by E30 as source appear.which power supply / charger adapter were you using? Did you used to leave it connected in stand by?
Is it a fast charger? It may supply a higher DC voltage than 5V.
iirc, there were reports that some fast chargers, after you plugged in a compatible device that triggered >5V, then plugged it out and plugged in a USB to barrel plug adapter without any handshake logic, would not reset to 5V and instead continued outputting 9/12/etc V.Every charger starts default at 5V and switches only to fast mode after extensive negotiation with the target device. I have a standard Samsung fast charger here continuously plugged in and it does all apparatus, from E-reader, tablet to all kinds of mobile phones in the house.
I don't think the introduction of MQA to the E30 ll can be expected at all.Will mqa support come to E30II with firmware update?
I received an E50 for another room and took the opportunity to test both side by side, with same cables, power, sources. Yes, I hear a difference, but very subtle, far from the way it has been put. I would say that the E30-II produces a flatter signal, but both have great musicality and the same performance, as expected. I also have an iFi DAC with a hybrid multibit chip and the difference is more noticeable. It doesn’t measure very well, but both E30-II and E50 may sound overly revealing to some people when compared to that one.UNLESS, my MBP 15-inch, mid 2012 has two different USB outputs OR my old Pioneer A505R amp's Tuner and CD inputs are different ... Have you compared the E30 II to any other DAC?
