    Default B&K 125.2 S2.... Opinions PLZ

    I am looking at this amplifier to power my LSI15's (hoping it will open up the bottom end a bit and give more overall control (running off a Yamaha RXV1800 now). I was looking at the specs and see that the damping factor is 180. Is that too low or am I misinterpreting the specs in some way. If anybody owns this amp and can give me a review on how well it stacks up w/ adcoms or rotels that would be great. I enjoy a warmer sound with full low end.
    Thanks oh wise Audio Guruus:)

    "A high damping factor indicates that an amplifier will have greater control over the movement of the speaker cone, particularly in the bass region near the resonant frequency of the driver's mechanical resonance."

    This is why I like Adcom's over some other brands. With lower dampening factor some speakers like the older Polk's will pop, because the amp doesn't have the ability to control the cone movement.
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks

    It's a solid amplifier and damping factor is not something to worry your head about.

    I have a 200.5 and think it matches wonderfully with the LSi15's. So while I don't have experience with that particular amp I'm guessing you'll be very happy with it.

    I know that amp very well. After dampening factor gets over 80, you can assure it wil handle most if not all speakers properly. It goes to 185 watts in a 4 ohm load and does it very very well. It will make your Lsi's sing. I also feel you should consider a B&K preamp. This will really make a bigger difference then just the amp alone. It will provide the correct amount of current required by your speakers but sound quality is going to be still of the sound of Yamaha.

    I really like B&K gear. It's so solid.

    I owned this amp for a while

    Pretty solid monster. Couldn't get it to clip.
