    MY TAKE:

    For more than twenty years Parasound has been a name synonymous with unequaled value. Their electronics are respected for both performance and reliability, and compete with significantly more expensive products. Modestly priced, previous offerings have changed common perception about the level of performance that can be achieved at the price point. - Galen Carol


    REVIEWS:

    Stereo+ (Norway): "Together, the Parasound P 6 and A 23+ are dynamite. Pure sonic magic with brilliant dynamics, delicious midrange and impressive resolution. To get such good sound for the price of this duo seems almost unnatural. One incredibly appealing preamp-amplifier package from Parasound."
