I have become a collector of vintage audio equipment and have been at it for about a year and a half. The Nikko NA-890 integated amplifier is the flagship of my young fleet. I rescued it from St. Vinnies for $50 knowing at the time only that I had finally stumbled across something special. It is stunningly beautiful, very well made, works flawlessly, and sounds great throughout it's volume range, which is sufficiently loud to get the job done in my garage. I am not an audiophile, my rating of this equipment is based on the aforementioned points.
