I bought the Playmate 2 after searching reviews and information about Burson Audio. Since I just need a USB/Toslink devise with Dac/Amp in one, the P2 made sense. Construction is excellent, it runs cool, lot of power and great sound and details. My unit use the stock op-amps and may use the Vivid units from Burson. I use my unit with a HiFiMan Sundara and ordered an Arya Stealth this week. Service? Wow, top notch. Highly recommended.
Up front I played with the different OpAmps and I definitely prefer the V6 classic dual and single upgrades. This setup with Meze 99 classics (standard cable better than silver) is really good. This setup makes the Mojo so boring and lifeless... so glad I gave Burson a try. Highly recommended and everyone should try the opamps... they really change the sound.
The good: Seems very solid and well made. Drives my mag. planar cans very well and some powered speakers (though that shouldn't be difficult).
The not so good: The volume dial has a nice touch, but often doesn't advance or back off in increments. The worst part is the loud(ish) thump when turning the unit off. Probably not a big deal, but it's not very 'elegant'.
Overall I'm pleased and I suppose at the price point, it's about right.
