      Comments about Onkyo A-9050 Integrated Stereo Amplifier:

      I want to say that the service with B&H was terrific. I ordered the unit online and had it in less than a weeks time. I found that their prices were among the best I could find online. The service was very smooth and would definitely order from B&H again in the future. I purchased the Onkyo A-9050 to replace a 25 year old JVC receiver amplifier that had served me well but was on it's way out. Originally I was looking at receiver amplifiers for a replacement but really could not find one to my liking. I then began looking at integrated stereo amplifiers since I don't really need the tuner anyway, and after a lot of research this was my top pick.First thing I noticed about the unit was that it is not an overly large amplifier in physical size which I really like. The build quality is quite good and the dials are ergonomic and have a nice solid feel to them. This is a very simple unit to use and has somewhat of an "old school" feel to it as far as functionality and design go. The amplifier section is very crisp and has minimal distortion even at high volume. Power is more than sufficient and would almost say that it is even underrated at its 75W per channel rating. I am powering Klipsch 600RF's with it and have not had the volume much past the 10:00 o'clock position. The sound reproduction is fantastic using the optical digital input. The bass is very clean and full even at lower levels. The phase matching bass feature is a nice alternative to a loudness button and gives a much fuller sound without muddying it up.Overall this is an outstanding amplifier and I really can't find much wrong with the unit for how I use it. It just plain delivers what it is suppose to. This is my first Onkyo unit that I have owned and am very impressed so far. If you are considering getting a integrated stereo amplifier, then you should really consider the A-9050.

        Comments about Onkyo A-9050 Integrated Stereo Amplifier:

        I'm no audiophile, so my rating is based on my perception of quality relative to the price. I needed DACs and amps to add zones to my sound system. I'm using Apple TVs, which output only digital audio. I was looking at the Cambridge DacMagic, but for only $ more, I got an equivalent quality DAC and the amp. It sounds great and has plenty of power. For the money, it was a no brainer purchase.
