Question 1

How do these compare to the NS-555s? I need to replace my floor standing 555s with equal-or-better wall-mounted bookshelf speakers.

Accepted Answer

I have the 777's as my main front L/R and the 333's as my 4 surrounds.  The 333's are less responsive in the low end then my 777's (as expected) but if you have a sub to fill in then I wouldn't be concerned with a theater environment.  Overall I am very satisfied with the performance of the 333's and am considering getting more for my office stereo (the low end response is sufficient for music).  They are not a small speaker (check dimensions) but if you have the right wall bracket (or shelf as I have) they are great.

Question 2

What is the frequency respond of those speakers?

Accepted Answer

Manufacturer's Specifications: http://usa.yamaha.com/products/audio-visual/speaker-systems/home-speaker-systems/ns-333/Frequency Response: 65 Hz - 35 kHzImpedance: 6 OhmsInput Power (Max/Normal): 150W / 60W

Question 3

Do these have mounting brackets or receptive screw in mounts on back?  thanks

Accepted Answer

It has a pre-drilled, single-holed bracket to mount on a wall. I would recommend to place a thick felt or rubber/silicone feet to the backside or bottoms of the speakers, so not to scratch wall or mar piano finish to bottom of speakers. These NS Series (333s, 444s, 555s, and 777s) are a fantastic deal considering the realistic sound which these speakers reproduce. All my speakers in these series (excluding the larger 777s), require time to be broken in. Mine took half a year of very infrequent music and movie watching via A/V system. You will discern a big difference of the sound once they are broken in. I knew it when as I was listening to a movie's intro. The sound was very room-encompassing. Enjoy the quality of Yamaha NS speakers and the elegant glossy finish.

Question 4

What cable would be the best for connecting these speakers to my Yamaha receiver?  What AWG would I need for the best possible quality sound?

Accepted Answer

Although not necessary for this speakers or home use, try to get the lowest AWG cable and as short as possible. Cable acts as a resistor between the amp and the speakers, so the more AWG the thinner the cable. Think a cable as a water hose, the longer the water the heavier is push out the water and the thinner the water hose, more difficult to pass water.
