Hi Austin_Jeff,
There are a lot of great suggestions here. IMHO If looking for the best sound for the budget you have - with the equipment you have...
I would take Wolf_Garcia's suggestion and hook up the Schitt Freya to your existing NAD 275bee . Freya is by far the best bang for you buck as it has several options and respectable specs. As you get comfortable with the set up you can roll NOS tubes and get a real sense of the tube feel.
The least expensive and best way to maximize your investment in the Focal Aria 948s is to take Larry5729's suggestion on upgrading your subs to the REL S3.
REL is known for their quick, seamless ,musical sub bass system with the Neutrik SpeakOn connectors. However Its only worth the investment with the connectors. I believe Analysis Plus makes The REL Cables on request. - if you decide to go this route request bananas connectors for the binding posts on the amp end. It will be easier to hook up.
Schitt Audio - $699

REL - $2,400

With about $1,500 to spare I would invest in a couple to decent power chords to maximize the performance of the NAD 275bee and Schitt Freya
I think you will be extremely pleased with the results.
What ever you decide, enjoy!
