    Default Is it time for me to get a new receiver?

    As most of you probably know by now, I'm using Harman Kardon AVR130 to power my new set of Polk Monitors. Power never was an issue before when i had MTX speakers with 94db sensitivity, but these new Polk speakers are only rated at 90db efficiency. When listening to music and stuff, i can notice small amounts of noise and distortion (traces of distortion seem to be present when the beat of a bass drum) present when listening to music above about -17 db (already very loud). Im beginning to worry that my little receiver is running out of juice for these speakers. My tone controls are neutral, and im using a Velodyne CHT-12 crossed over at 60Hz.

    What should I do to eliminate this? Should I....
    1) leave it alone... its barely noticeable anyway...
    2) Get a beefy receiver (HK AVR635 or 7300)...
    3) Get a cheaper HK receiver with preouts and get amps for the fronts?

    Any tips are welcomed

    I agree, #3. Once you hear the difference you will not look back. I own a Yamaha RX-V1500 and use a Rotel RB-1080 for the fronts.

    Switch the crossover on your Velodyne to 80hz.
    Switch all of your speakers to "SMALL" on your H/K- and cross them over at 80hz.

    Thanks for all the tips. I actually used the tone controls to reduce bass from neutral (12 o'clock position), i move it to about 9 o'clock and got rid of any distortion probelms so I think i will leave it like that. I don't particularly like the sound crossed over at 80 Hz.... probably has to do with the fact that my room is small.

    Anyway, what amps should i be looking at (please nothing TOO expensive)

    Thanks again!

    This one looks pretty nice:

    Would an HK AVR235 or 240 be a good preamp for one of these?
