Preamp upgrade

Hi guys,
I'm looking to upgrade my preamp (Parasound Halo p5) and would greatly appreciate some suggestions in the $1500 to $2000 range. I would consider pre-owned tube or SS options. Living in Tucson, listening to options before purchase is not likely.

My system includes a Parasound A21 amp, bluesound node2i, Tekton impact monitors and a single (soon to be dual) SVS sb3000 sub. I primarily steam classic to hard rock, funk, reggae and classical via Qobuz.

My listening space is about 12'x20' and is open on the 20' side. The ceiling is slightly vaulted with a max height of 9'. 

Thank you all for your considerations.
