Up for your consideration is a beautiful Audio-GD R28. It is from the 2019-2020 collection and has an R1 R2R DAC, and a NFB-1 Balanced Headphone Amp with 9 watts into 40 ohms. It is extremely well built, overbuilt with great parts and musicality. It punches way above its price point and comes with all of the original accessories. Original packaging, power cable, USB cable, and the jumper kit for upgrading firmware.

It works perfectly and is in beautiful condition with very few to no scratches. I will give it a conservative 8/10 due to being a few yrs old, but I doubt you will find a nicer R28 from this vintage online.

Thanks!
