Yystantabarbera we sell the NAD and the Anthem products.
A viable solution is the Anthem STR preamp coupled with a really good solid state amplifier.
The Anthem STR we feel is a bit less colored sounding then the NAD products, add a Coda .8 amp and an Innous streamer and you will have a fantastic combo.
The NAD Hypex amp is okay, what you are liking is the Nad M22 which is a warm and full bodied preamp it is a bit more colored than the warm sounding STR.
Our combo for you would combine the excellent Anthem Room Correction which is a huge bonus, the new genesis version is supposed to allow for custom Eq which would allow you to fine tune the Persona 3F to add a bit more mid bass giving them a bit more warmth.
The Coda .8 is super open, warm and resolute just a fantastic amp for the money, and the Innous Zenith server presents digital with a full bodied and liquid presentation. This is a very well balanced combination of great components.
