Summary: Just unpacked this unit from Amazon, and I like it in many ways. The sound is good, the interface is clean. It's basically what you'd expect from an integrated amp. However, I do have one criticism. Surprisingly, the subwoofer output is active whether you select the A or B set of speakers. If the intent is to provide multi-room capability, or even to provide the capability to use two different sets of speakers in the same room (why?), this doesn't work.
The Yamaha A-S300 - A Splendid Integrated Amplifier

Summary: I received this Yamaha A-S300 Integrated Stereo Amplifier on December 17, 2013 and installed it into my system yesterday, December 18. To make a long story short, it is my opinion that this amplifier is a superb instrument, one which will bring a lot of pleasure (and excellent sound quality) to its owner(s). Please read on, if you wish, for my reasons for liking this unit so much.
Summary: i initially got the Yamaha as201 receiver and trade it in for the as300, and what a difference. This unit is more dynamic has highs, middle and lows. The nobs are plastic, but look like metal. The speaker wire connectors are really nice. Bought the unit to test my DIY speaker builds, and it will do nicely.
Summary: Handsome, simple design. It's nice to see that Yamaha realizes people want a bass and treble knob. Equalizers are ridiculous. This powers four Polk bookshelf speakers and I have two Polk subwoofers running as well which required a y cable running from the LFE. The remote has a nice metal face and is straightforward. The volume knob is a sore spot with some fellow reviewers as they think it looks cheap but that seems to me to be nitpicking. Beautifully simple unit.
Summary: This amp really opened up my speakers. I'm getting more detail with better staging, Power to spare; I'm running quality book shelves, and the decibels at full gain will chase grease off a gridle. This is not a pretty unit. All black, with tiny LEDs, it sits looking gloomy and unusable. I also don't like having some functions dependent on the remote.
Summary: I ordered the A-S300 to replace my 30 year old power amp. My Brother has a Yamaha Reciever and he really likes it, so I took the chance. In a word, it sounds great. I called Crutchfield support with some questions about hooking up verious components and they were very helpful. I will definetly order from Crutchfield again!
Pros: Easy to set up. Fits perfectly in my Entertainment center. The "Pure Direct" mode is a great feature. Controls are simple and easy to use. Great overall sound. Great customer service from Crutchfield.
Cons: Non! Unless you like super heavy bass, which I don't!
