What The Fidelity??

OK. So here is what I currently have, followed with what I was thinking of doing and ending with what a "pro installer" is recommending. Who can give me some opinions and insight?
Three years ago we moved into a new place and I called an installer to get things going. I only had Klipsch ref-62's for fronts and a 150.00 Samsung Blue-ray while watching a 46" panasonic plasma from COSTCO. That's it. He set up a Denon avr1910, Apple TV and a Belkin surge protector. Wireless control with a "genious 900 remote.
Time for an upgrade. I have ordered the Tekton Pendragons. Eric Alexander paired the M-lore center channel and sides for a 5.0 system. (I'll wait for now on the sub). I'm thinking either a 55" or 60" Panasonic VT50 or GT50. Room treatments from GIK (Brian has been quite helpful).
So, a new "pro installer " came over and right away said I have to forget about everything I have been thinking. He said the Pens would be too bright (Really!). The Denon is also too bright and harsh. The Blue-ray is crap. And finally, the TV's we buy at retail stores are also crap. They are tier 3 models. He can get the top tier models (better glass, better construction) and calibrate it before the install.
His line up is....
NAD T 757 receiver
NAD T 767 Blueray
Paridigm Studio 20 fronts
Paridigm Studio 10 rears
Paridigm Studio CC 490 center
J-29 speaker stands
Paridigm dual 12" ultra cube subs
HDMI Cable
He also suggests a processor (a 5,000.00 demo for 2,800.00) This total comes to around $14,000.00 not including the demo but it does include install, programming and calibration). So the question is......My price point with the Tekton speakers, GIK and HDTV would be around 7,500.00. Should I follow the expert advice or will my present components do the job?? By the way, the Samsung UN55ES8000ss is 4,000.00!
