Silly me, you're right. I don't see any 4-pin XLR to female TRS plugs on that website... I guess you could also just get a 4-pin XLR and a TRS female separately and join them with wire. You could connect the TRS sleeve to either negative pin on the XLR. The unconnected negative pin's banana plug wouldn't need to be connected. Screw terminal plugs are harder to find but do exist if you don't want to solder.
Yeah, I'll see if this I'll solder it myself or order/add in another silver adapter to maintain high quality. For D2000, wire quality isn't too big of a deal as I have the stock cable and recabling is just not worth it. Although for a TH-900 in the future it might be worth it. I'm already loving the LCD-3 with Emotiva so much right now. If the D2000s sound good as well, then I guess the TH-900 will as well. After that, just pick up a killer DAC and kill it a year.
I'll talk to the Ebay seller about a 500 ohm or maybe Headphone Lounge.
...but that First Watt though.
