Thanks DanBa ... good to know.

Startech looks like this:   http://ca.startech.com/Cards-Adapters/Sound/USB-Audio/USB-20-to-Audio-Adapter~ICUSBAUDIO   Matrix Mini is this (but this might be a slightly newer version)   http://www.matrixelectronics.net/matrix-mini-i-c-66.html   Both work fine with my Samsung S3 and both...

I upgraded to Android 5 on my Nexus 7 2012 (sideloaded using adb as the OTA wasn't being pushed). Native USB audio does not work with the two DACs I tried (cheap Startech thing and Matrix mini.)   With cyanogenmod both DACs work fine.

+1 Integration with BubbleUPnP would be a major win for UARP.

I thought I'd chime in here too. Got the USBROM and after a few self induced screw ups I got my Nexus 7 to easily recognize my Matrix Mini and a cheapo Startech USB DAC.   Using BubbleUpnp I'm streaming FLAC files flawlessly to my stereo.

Herus looks nice. Here's an OTG cable I found for a few bucks:   http://dx.com/p/micro-usb-male-to-usb-b-male-otg-data-cable-black-25cm-233994?tc=CAD&gclid=CL_Ut-TygLsCFYY1QgodN1sAng   Any reason why it might not work with a Galaxy S3?

Yes. The Jameco one has the correct (negative) polarity.

No toslink on that one though. If you want to stay in the pro audio world you could try this:   http://www.amazon.com/Roland-Cakewalk-FA-66-FireWire-Interface/dp/B003UVWU5Y   a bit over $200.00 but has optical in (but no USB!). I had one for a while and it's nice, but runs hot.   The...

Quote: I just got my SR-407s yesterday driven by an SRM-252II. I spent a long time comparing the Stax to my HD600s and Woo WA2.   The 407/252 combo is really nice and I would have to say on most material clearly superior to the 600/Woo combo.

So my Stax system arrived a few hours ago. I got it from elusive disc with their 10% sale and it consists of an SR-407 and a demo SRM-252 II. Been listening to some Beethoven violin sonatas and some Vivaldi as well as some music that I've written. This is very good stuff.

Two part question:   Can anyone tell me what the output impedance of a Stax amplifier is? Any Stax amp is fine I just want to get an idea. The only thing I've seen that has this spec is the Mal Valve Three which is apparently 600 ohms.   Also, does it make sense to use the same...

By way of some background I picked the Jameco wall wart for you because it was the same spec (power, barrel size,) as what this guy ordered:   http://www.head-fi.org/t/447175/stax-2050a-srm-252-information   Jameco changed their part numbers, but I looked at both data sheets and they...
