I’m the second owner of this xduoo ta-10r. This is the version with the akm4493 DAC chip. The original owner switched out the stock tube with a nos GE tube. I’m not sure of the exact model, but it sounds excellent. I’ve had the mt-602 in the past, and this is step up in soundstage, detail, and power. I have a few new stock tung sol 12au7 (6189) tubes I purchased from tube depot if you’d like those too for $25 each. It’s built like a tank. I don’t have the original box, so I knocked the price down. I’m not using it much these days, but it deserves to be.

Price includes shipping, CONUS only. If you live in the Philly area, I’d prefer pick up to shipping. PayPal preferred
