    What does "B" stock mean? Is this a refurbished item?
    Alec P on Apr 27, 2017
    BEST ANSWER: basically yes, however this no a bad thing since you know it was done by Monoprice and eliminates the possibility of a dead unit and it comes with full factory warranty. This is a great company and I have purchased from many times, never had a quality or any other issue with them.
    is there a rack mounting kit for this unit (Monolith 7)?
    Mikhail F on Apr 27, 2017
    BEST ANSWER: No. Need 5u Rack shelf that can support 100lbs.
    Where do the sources plug into it?
    A shopper on Apr 27, 2017
    BEST ANSWER: The sources will come from either a audio or av receiver, or a preamplifier. the sources will plug into one of these devices. souurces can be the receivers tuner, a dvd/cd player, a turntable or a seperate audio tuner. Hope this helps
    Does this amp handle 2 ohm loads? I have a pair of Martin Logan Odyssey speakers that have an impedance dip to around 2 ohms that I want to use as my front speakers in 2 channel mode.
    A shopper on Sep 15, 2018
    BEST ANSWER: Yes, this can handle 2 ohm loads without issue.
    I see the new unit with XLR's is made in the USA, is this older one built in the US also?
    New User U on Apr 13, 2018
    BEST ANSWER: Yes, all the Monolith amplifiers are built in the USA.

    Amazing value - small scratch
    B stock had a scratch on the side of the chassis and the outer packaging was really beat up but otherwise everything seemed to be like new and working perfectly

    Thoroughly impressed. Best amp made for the money.
    This thing is a beast! 93lbs of pure beautiful sounding power. I have this paired up with a Denon x4400 AVR and SVS speakers all around which include the prime towers, prime center and prime satellites and a PB2000 for the low end.

    I couldn’t be happier with this Amp, this is exactly what I needed to somewhat “finish” my system. You know a home theater is never finished. But I will own this amp for years to come. Very clean and plenty of power to bring my surround to reference levels with ease.

    Brings the muscles to your home theater speakers
    Sounds fantastic, brings out the dynamic scenes at higher listening levels where a regular avr would struggle. It's pretty heavy and seems to be built well. Really happy
