Yes, it's a tube/mosfet hybrid amp. I believe the mosfet output stage runs in Class A. The amp's heat sinks and tube does get hot after it has been on for awhile. I have only had it since Friday, so I'm not sure how much influence the tube has on its sound. I will be trying some different tubes, but have not had time yet. It replaced a Little Bear p1 tube hybrid amp but it is much more refined sounding than the Little Bear and the gain is adjustable on the Sunrise. Also, you can easily set the tube bias on the Sunrise
I have used the headphone jack on an NAD receiver for a long time and the Sunrise is more detailed and a little more refined than the NAD. I have 3 Cmoy type amps and have tried the Musical Fidelity V-Can, a custom made burr brown opa627 amp and an Earmax all tube amp. The Earmax amp was very good but could not drive the Grado's very well. So far, the Project Sunrise sounds better than all of the above.
