The amplifier is beautiful but the preamp, sadly is from the 'butt-ugly front panel' era we absolutely hated when selling Yamaha. Design wise, it is a fiasco and is essentially a high end preamp with a DSP3000 in it as well. It was $12k when we had one to play with and there were 3 in Australia (apparently Allan Bond had a set). I have no idea what they were thinking design wise, but they sure fixed it with the softer knobs and slightly curved panels the following years. Too many mismatched angles, odd sizes of buttons and placement and visually just a mess.
The amp is a jewel though.
