    Very nice! Updated after returning
  

*by J***S on Reviewed in the United States on 19 December 2021*

I had been wanting something like this to come along (tube preamp with DAC and sub out).  Most other tube DACs are considerably more expensive in the audiophile world.  I've tried out several other preamps like this (Chinese brand) over the years.  Some I've sent back and some I've kept, and this will be a keeper.  I like that RCA and USB cables were provided.It's important to know that I upgraded the tubes right away, and I have not been able to try out the stock tubes yet.I'll first comment on build quality/aesthetics.  The preamp is hefty and solid, and tubes sit firmly in the sockets.  The power/source button provide a firm click feel, the bass/treble knobs turn smoothly, and the volume knob has a very satisfying tactile turn.  There are small white LEDs which illuminate at the base of the tubes - very subtle.I have tried two different methods of connection so far, the aux and optical.  Both have worked perfectly and provide very good sound in combination with my audiophile power amplifier.  Sound is clean, clear, and images quite well, but with separation of instrumentation, etc.  I'm sure this will develop as the tubes get more play time.My speakers benefit with the use of a separate subwoofer, so it's very convenient for this preamp to have the dedicated sub output.Overall, I'm very impressed with this preamp, and I'm very glad that here in the US I have access to these Chinese audio companies who keep developing quality products like this.EDIT: I ended up returning this because I determined that it generates way too much noise in the line.
