Hi, I am new to putting together a stereo. I always used to buy a surround sound system already put together or but a portable stereo with a handle or just use headphones. But putting adding individual components has its personal touch and it has a better sound as I understand it. I currently have Fluance XL7F floor speakers with the following specs: SYSTEM TYPE 3 Way - 4 Driver Floorstanding Main Speakers TWEETER 1 inch Neodymium Balanced Silk Dome Ferrofluid Cooled MIDRANGE Dual 6.5 inch Polymer Treated Butyl Rubber Surrounds Separate Enclosures WOOFER Isolated Down-firing 8 inch Polymer Treated High Excursion with Butyl Rubber Surround POWER HANDLING 80 - 200 Watts FREQUENCY RESPONSE 45Hz - 20KHz SENSITIVITY 89dB CROSSOVER FREQUENCY 800/3500 Hz Phase Coherent - PCB Mounted Circuitry IMPEDANCE 4 ~ 8 Ohms ENCLOSURE Tuned Rear Port Bass Reflex Tower Design DIMENSIONS (H X W X D) 45.8 x 8.5 x 13.4 inch WEIGHT 45.2 pounds/speaker and I have the Denon AVR-S900W on the way with the following specs: Power and Processing: 7-channel amplifier 90 watts per channel into 8 ohms (20-20,000 Hz) at 0.08% THD, with 2 channels driven Dolby® and DTS® surround sound decoding, including Dolby Pro Logic® IIz upscales standard-definition video signals to HD and Ultra HD (up to 4K) Audyssey "Bronze" speaker calibration and system optimization includes: MultEQ® auto setup and room calibration delivers balanced, dynamic sound for as many as six seating positions (microphone included) Dynamic Volume anticipates loud sounds to keep volume levels even Dynamic EQ improves dialogue, bass response, and surround channel levels at lower volumes Will the Devon be enough to power the Fluance speakers? Or do I need to get a power amp? If so, do you have any suggestions? Thanks, Matt
