What preamp with your GaN power amp?


I plan to buy a GaN Class D power amp in the next few months.  I currently have a tube integrated amp, so I will need a preamp to go with the Class D power amp.
If you own one of the new GaN Class D power amps, please post which preamp you are using with it?
I am particularly interested in which preamps pair well with AGD Audion, LSA Voyager, and the Peachtree GaN power amp.

OP, the Atmasphere is an excellent preamp, very transparent and neutral I can vouch for it as I own one. The Supra is a good preamp too but completely different sound, it depends on what you like.
I'm using my Atma-Sphere MP-1 with mine since the amp accepts balanced inputs.
I 'm using a DHT/ 6SN7 Supratek pre with my AGD Audions and it's an excellent match. The realism is uncanny very musical, everything is just right i'm not wanting for anything.
