Summary: *ASSAULT AND BATTERY* I have mixed feelings about this unit. I bought it as an Amazon Warehouse Deals open box and I'm sure it was fine when it left their warehouse. But it was packed with almost comedic negligence.
Summary: I've been involved with stereo equipment for more than 35 years, I've never come across an all out bargain like the onkyo. The sound is smooth and powerful, with great detail and balance. To have an IA with both a MM and a MC phono pre-amp is very unusual--not to mention an optical input.
Summary: This integrated amp is perfect for anyone interested in an audio only system. I paired it with 90dB speakers (Monitor Audio BX2's) and could not be happier. The sound is clean, open, and marvelous. Incredible level of detail lets me spend hours just listening to music without fatigue.
Summary: I am a professional classical cellist. I listen exclusively to classical music, which places high demands on audio equipment: huge and often sudden dynamic changes, complex textures that demand excellent instrumental separation, and a variety of timbres that are difficult to reproduce accurately.
Summary: This amp has a wonderful sound, however, I just could not get over the following: -buzzing, -high heat output -lack of preouts -lack of loudness (Onkyo calls it Phase Matching Bass Boost) -worst remote I've ever seen or used It ended up going back. Oh well.
Summary: This Onkyo amp has so much promise, and when I first got it I was excited about it. I let it burn in over 100 hours, and I just could not eliminate the persistent hum it has. This actually interferes with quieter passages of music, such that I had to return it.
Summary: Bought this amp to power custom-built speaker set for Samsung LED TV, not for surround sound system. It works very well. The only negative I have noticed is no on-off feature on remote. Have to use the on-off button on the amp.
Summary: I paired this amp with an Apple TV (latest gen) over optical audio in, and then connect 2 pairs of Klipsch outdoor speakers for the pool/patio area. This allows me to stream my iTunes library over wifi, control the content and modulate the volume straight from any iPad or iPhone.
