Full Range under $5k-ish

I think in the PBN speakers you will get exceptional sound. You will also get exceptional customer service.

Klipsch rf7lll's. I've owned many, much higher end speakers, but with McIntosh gear, I absolutely love them. Especially for your room size. Rock and roll!

For around $5,000 ,
I would look at TEKTON speakers and a pair of Tekton subs..
and possibly upgrading your amps to a tube variety, Quicksilver, Decware, VTA, Don Sachs..


I have on order a pair of Double Impact SE’s at $4,500 (2,000 off MSRP) , These are going to be hard to beat for the $..
They are on sale right now, and since I didn’t want the mirror finish on them Eric gave another $1,000 discount..

I’m upgrading from the Tekton Seas Pendragon’s..

My system for reference :
Apple TV4 (streamer) —needs upgraded—
Oppo 205 (DAC-CDP)
Denon DP59L (TT)
Decware ZP3 (phono pre)
Decware CSP3 (preamp-headphone amp)
Decware ZMA (35 watt PP amp)
Tekton Seas Pendragon (speakers)
Tekton Cinema (18” sub)
Cullencable loom (silver plated copper)

I'll throw my vote in for ProAc. Have owned a pair of DT8's for almost a year and have been very happy.
