    The maximum power for these speakers is 80 watts. Presently am running my M-85 volume at the halfway mark, am i driving the speakers at more than the capacity since the amp is rated at 240 watts. Thank you.

    I run my M-80 attenuators at min.And use common sense when playing with it. BTW The M-80/ M-85 is closer to 300 wpc than the rated WPC. The M-85 is and M-80 with all the service bulletins implimented.Only difference between the two is cosmetic.( front and rear panel )

    Thanks for the info Dave. By the way, thank you so much for the recap on my C-85 and the caps and instructions on the M-85 . WOW never thought my system would sound this good. Next project recaps on speakers . Still delaying this project though since these still sound good. If ever, thinking of using the Jantzen crosscaps since a lot cheaper than the Mundorfs. Warmest regards.

    I would imagine your 690's are what.. 96db @ 1 watt @ 1 meter. So they will get real loud around 5 watt or less.

    I would prefer the original 690 mostly because it is 96 dB @ 1 watt @ 1 meter, they are rated to 60 watts
    I don't know what it is on the 690II, but at max input of 80W on 690III you get more volume on the original, and multi-amp inputs:D
    who knows what max input and sensitivity are on the 690II?
    at some point, I want to get 690s to compare to my 670s

    I don't think any of my Yamaha 690 series sounded like they were rated 96db.
    That's pretty high, imo.

    Don't be so hard on yourself:whip:
    I'm just saying the 12" 3-way 690 didn't seem act any more or less sensitive than the 12" 3-way 90db 690II's or even the 90db NS-1000.
    Thus my surprise they were rated 96;)

    I run my NS-690 mk1's with a JPN domestic B-5. I keep the attenuators typically at 7 and it sounds good to my ears. They don't seem to be overloaded and the boost in power going from a CA-800 to an AX-900U and then to the B-5 seemed to only
    improve the sound. I also never really push them it's mainly a bedroom setup for moderate volume. I actually have an M-85 sitting right next to the B-5 but don't use it much at the moment.
