Another GaN smaller integrated, Technics SU-G30 has everything bar the kitchen sink.

I actually have this model and have been using it as my main source of amplification while waiting for a new amplifier to arrive (one of my JC-1s broke).  I think it is quite a good value used (about $2K) since you can just plug in a digital source and don't need an external dac.  

There is one huge caveat IMHO with Technics implementation of this technology in my experience with the SU-G30.  The analog input is digitized, and that conversion adds a significant digital flavor to the sound coming out of the speakers compared to a pure analog setup (in my case BHK pre and JC-1 amps).  

I have used the DLNA compatibility to wirelessly stream music off of a Sony HAP-Z1ES server, but I found that I greatly preferred the sound quality of something directly connected to the unit (like a CD player or music directly off a USB drive).  However, the Sony is not known for having a really clean digital output, so my results are certainly not conclusive.  I do like the built-in internet radio feature. 

I have hooked up a Holo May dac and Marantz SA-10 CD player to the Technics, and IMHO the sound is improved over feeding it a digital signal, but only slightly.  With my regular amp and preamp, the Holo May will make some digital recordings sound as good as reel to reel tape or an excellent vinyl system.  When played through the Technics, the sound of the Holo May is changed into something resembling a delta-sigma dac type of sound.  

 The G30  never sold very well to begin with.   Now that the newer, much better looking, and cheaper SU-G700 Mk2  is coming out, there doesn't seem much need for the G30 (which is also pretty old at this point).
