Nikko Audio - Beta II & Gamma I silver

Does anyone know anything about the Nikko Audio line of gear or can send a link for Nikko info?. I have an opportunity to buy a set that includes a Nikko Beta II Preamp and a tuner called the Gamma I (both in silver). I can't find much info about Nikko gear and have not seen even one review! I have had mixed reports from my friends. Some say the Nikko stuff was crap while a few swear by it. I'm told that Nikko was more well regarded in Europe and overseas that it was here in the U.S. I am also told that the silver components (which I believe were built earlier) are much better than the black Nikko gear. The Beta I preamp I auditioned seemed well built and sounded good pushing a Hafler DH120 amp into some vintage Altecs. I am looking for the "best for the bucks" and I am on a very limited budget ($500), so that is why I am looking at used gear hoping to luck into something phenomenal (fingers crossed). I want the smoothest, quietest preamp and the warmest, most tube-like musical sounding amp I can afford. This will be for the top of a bi-amp on a pair of Infinity 2.5 (EMITs & EMIMs)so I don't need much power. I already have a Carver 1.0 for the low end. If I don't get this Nikko gear my other considerations are NAD or Hafler. Any input from the big brains and experienced ears will be appreciated.
Thanks for reading this!
