I bought this DVD for less than 15 dollars based on a very favorable review on the sound quality.
For the price paid I did not expect anything out of the ordinary. But I was pleasantly surprised to connect it to my Yamaha ns 1000 and Sony TA 2000f preamp boxes with the TA 2000 power. It's detailed and articulated sound looking like the best recordings that each instrument had a separate channel and microphone for their recording. With powerful bass and a midrange sweet and sharp well defined, creating an atmosphere almost surreal, with physical presence of musicians. A real bargain for the price and sound quality.
