Hey there,
You have a nice combination already. I'd suggest a subwoofer and room treatment are better options than a new amplifier from where you are.

Power Amp Question
Question: how to match a power amp to my system using an integrated amp as a preamp.
System:
Triad Gold LCR In-Room Speakers 4-OHM 100-400 watt
Audio Tecnica AT-OC9XL Dual MC cartridge
NAD C356 integrated amp
Rega Aria MK3 (recently added)
Thank You
