Looking for Reviews of a Few Speakers

[Cosmic_Error]

I've heard about a few speakers that seem promising but I can't seem to find many reliable reviews on a lot of speakers, if you know of any good reviews of these speakers or just have an opinion of your own I would love to hear about it. Also any amp pairings would be helpful because I have no clue about amps. My amp budget is about $2000. Speaker budget is $3000 but I would like to be closer to $2000.
The speakers I'm interested in:

• Paradigm Premier 800F - Recommended by audioholics
• Monitor Audio Silver 300 - Recommended by stereophile
• Ascend Acoustics Sierra Tower w/ Raal Tweeter - Somebody on this forum, I forget who
