Has anyone actually, independently tested the PA10 for power and other tech specs? If so, a link to the source would be appreciated.

Maybe try contacting Linsoul and see if they have any information to help you.

Ok, this sums up what I posted in the PM on how I got it to work. Maybe this will help. "I got it figured out. In settings - connected devices .... USB option was always greyed out. My PC didn't recognize the 220 until I accessed developer options and turned on MTP file transfer in the USB...

I found it. It's a PM string with another member. ... See if this helps ... https://www.head-fi.org/conversations/dx220.2974438/#convMessage-8157995

I had to do something too for 220 to be recognized (Windows 10) but cannot remember what it was. Had something to do with switching usb options in 220 to allow file transfer but i couldnt access those options. I had to do something to be able to access those options. I think its posted in...

Are you sure Cato isn't screwing with you ...

Does the same thing with the P1. Just cannot provide the juice. I've bitched more than once about the way in which A&K states their output power specs. Enough said.

For shielding?

The Q15 should be a very good value at $400. $100 more than G5 but more features. Plus, AKM's flagship chips and looks like plenty of power on tap. I don't believe it uses THX amplification which is personally why I'm a bit interested even though I'm not really looking for any new gear. And...

I don't know about the W2 but the G5 isn't "fake balance". It's not balanced at all and it doesn't claim to be anywhere in the specs. The 4.4mm output is for convenience only.

Cayin N7 has class A or AB switchable amplification.

You just nailed my biggest issue with A&K. It will most likely do the stated output voltage ... into 47Kohms

Same topology as NX7, a little less powerful. Makes more sense to purchase NX7 if you only want the amplifier section. NX7 has a little more power and is less expensive.

I suspect that your ears are just too good for the G5 then. Why do I say that? ... As just one example ... There are plenty of folks who claim they can hear differences in the filters. Subtle is how I hear it described. I have no reason to doubt them. But you claim to be able to "easily"...

Don't really have much advice. Personally I'm very pleased with the G5 and it's size isn't an issue for my use case. I think it sounds fantastic as a DAC + Amp. I'm feeding it via usb with a Hidizs AP80pro as the transport. I personally am not at all impressed with what comes out of the...
