Summary: I have always been an Onkyo fan and have bought several Onkyo components over the years. This purchase was a big mistake. Sound is fine, build quality is fine, but there is a significant chronic buzz coming from the device that is noticeable during quiet passages and particularly noticeable when the CD ends and the device is in idle mode. I was not happy. For newbies, the term is magnetostriction and the buzz is most often emanating from the transformer.
Summary: Considering its price, I think the sound is very good. However, as many people have said, there is hum from the chassis (not related with volume, and not from speaker or headphones). If you plan to use it as a desktop amp, the hum may disappoint you, especially when it's used for speakers in silent night. If you are away from it at the distance more than 3 feet, it will be hard to notice the hum (but still depends on how sensitive your ears are).
Summary: I purchased an Onkyo A-5VL 9 months ago and I'm quite happy with it. I wanted an integrated amp primarily for listening to music, but that could also double as a 2-channel home theater system. The A-5VL stood out in my search primarily because of it's features: a phono preamp, remote controllable volume and mute, a volume knob, digital inputs with high-quality A/D conversion, and a low profile to fit in my small cabinet.
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: 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. The quality is far beyond its price point. Am I impressed---U BET.
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. It was just sitting on the very bottom of a large corrugate box with some brown paper tossed on top, and as a result it arrived beaten up. The front left foot had broken off due to in-transit trauma and was loose in the container.
Summary: I bought this integrated amplifier and conected to KEF reference speaker (4ohm)it drive my speakers efortlesly without any other issues like hum or noise that you read ridht here.It didnt got hot only warm to the touch.I t punps 80 watts at my KEF speakers and it souded very clean.It is heavy and well made.At this price point you cant get better than this.
Summary: This little--but heavy and nicely built--amplifier has the potential to be a very good or perhaps excellent performer. I listened to it for a few hours, but just could not stand the hum/buzz coming from the amp. The amp seems to have noisy transformers, as some reviewers have suggested. During quiet passages, the transformer noise is audible. It is sometimes audible when the amp is playing at a moderate level.
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. This is a secondary amp that is solely used for this purpose. It's located in a climate-controlled annex to the garage on the far end of the house. Works awesome!
