I need advice on which speaker

i never even heard of a lot of these speaker recommendations 

There are a ton of good speakers out there. Many of them are small businesses in it for as much the love of sound and craftsmanship as they are for business. Most speakers not found in big box stores are well made and appeal to different sound and listening preferences.  

I'm interested in SALK speakers 

basically got it down to  Salk soundscape 8, Revel F208, RBH SX-T2, 804D3, Monitor Audio PL200 II

Your Parasound puts out 240w at 4 ohms and 87db sensitivity, which puts it at the top range of the Salk Soundscape 8 ($9K), which is rated 100-250w. However, I doubt you'll be driving it for very long at those high wattages.

The Revels ($5K) are about 89db and can take up to 350w at 8 ohms. Your Parasound puts out about 160w at that resistance, so it should drive the Revels. The Revels are also tremendously well-reviewed.

The Monitors ($7K) are 90db and should fit very well with the Parasound, though I'm slightly biased against huge outfits like Monitor, even tho their speakers are quite good. Still, they use underhung voice-coil technology and for that I'd choose my Acoustic Zen Adagios.

I have no experience with the RBH's.

All of these are big speakers, so fit and finish should also be a consideration unless you don't mind sharing the room with two robots.
