    Takes music and movies to the next level!

    I added the Marantz MM7055 to my Denon AVRX 6700, 5.2 setup with SVS Ultras. I was content prior to adding the amp, but I'm so happy I added the amp. Such an improvement in sound quality. My SVS Ultras are running off the amp leaving the 6700 to power my 2 SVS subs. Cleaner, more defined sound with appropriate umph. My only regret is that I didn't get the MM 8055 for more power.

    Great Addition to My AVR Rack!!

    A great addition to my home theater. I purchased this amplifier so i could add a 2nd pair of dolby atmos in ceiling speakers to my theater room to run 7.2.4 and everything is perfect! I use the amp to run my front stage and rear surrounds and have my avr power the rest, couldn't be happier.

    Easy to use, good sound

    Purchased this to augment my 9-channel receiver in an 11-channel system (I was using an old Insignia stereo receiver to power the rear Atmos/ceiling speakers). Easy to setup, the trigger input works well to turn on the amp automatically when the receiver turns on. Using it to power the front L&R, center, and rear surrounds. Sound quality is good. Surprised that I have to turn the volume up to the same levels as before; since the Denon receiver is 140w per channel into 2 channels, I was expecting the 140w per channel of the Marantz to play louder, but it doesn't.

OSD Audio - HTA7200 Multi Channel (7X) 145W/Ch Home Theater Amplifier
4.0(1)

The HTA7200 can easily achieve the reference cinema sound levels of 105dB from all channels. The HTA7200 is rated at 210 Watts per channel, all channels driven (not just one channel, as stated by most competitors) into 4Ohms. Used with typical speakers this allows for a sound-pressure level of 112-115dB, 7-10dB more than required for reference sound levels. The additional dB’s means the amplifier is working well within its normal range, and this keeps the distortion low. (A good example of this is turning your TV up too much - it does not sound good. This is because the closer you get to full power the higher the distortion.) With this amplifier at 105dB, the distortion is below 0.01%.

With this amplifier at 105dB, the distortion is below 0.01%.By choosing the best components, we can also achieve 110dB SNR at full power, this allows for a very wide dynamic range, allowing you to hear the softest and loudest sounds more clearly. This combination of performance specifications is hard to find from any amplifier, regardless of price. By choosing an OSD HTA amplifier, you have achieved the goal of great performance at an affordable price.
