yamaha dspa 1 processor


Posted on Feb 6, 2014

It is Yamaha`s latest statement piece, and it has everything we could possibly ask for in home theater processors, including high performance. It`s expensive, but worth it. Up until this point, I have not been a one box solution aficionado. That all changed when I first turned the DSP-A1 on in our home theater reference lab. There is a tendency to call all one box surround sound components `Receivers` because

it is a convenient word, and most of them have tuners (that`s why they are called receivers). But the DSP-A1 does not have a tuner, so it should be called a "Processor/Amplifier". I have seen it referred to as an integrated amplifier, but that term does not really define this type of product. Anyway, it`s all just semantics. The fact is, the DSP-A1 is a masterpiece. It`s rated at 110 watts rms per channel into 8 Ohms for the front left/center/right and rear left/right, with 35 watts per channel going to the "front effects" channels. Most of the inside of the chassis is occupied by circuit boards. The power transformer is huge, but there is not much in the way of power capacitance. This is pretty much the way all receivers have been, are, and probably will continue to be. As a result, I would estimate a more realistic 60 watts or so per channel when all channels are slamming out action movie sounds simultaneously. That`s still not bad, and better than most other one boxers. However, processor-wise, the DSP-A1 is the most exciting product to come along in quite a while. If you used the pre-outs with a multi-channel outboard power amplifier, this unit would still be worth the $2, 600 just for the processing power (however, the built-in amplifiers sound good, which I`ll get to momentarily). You can spend twice this much on other processors, and get only a fraction of the features the DSP-1A has. Do the $5, 000 processors sound...
