Clean layout, easy to modify and work on. Sounds detailed and accurate to me.

Power supply does let a little low level hum thru. Was designed to have good sound, but they didn't filter the power as well as could have.

Model I have is the one with the additional feet, better power cord, AC filter and the DAC board installed.

Have been quite pleased with this unit. At this price point this is a very good unit. Sound is very pleasant, clear and distinctly detailed. I have changed tubes and you can vary the sound somewhat by picking a tube that suits your prefrences.
