Dear Fred:
Thank you very much for your kind words. I have not forgotten the AU-X1 issue. I'm still waiting for answers. I have been so busy, and just start writing e-mails again. If you can share the info on B-2301 and C-2301, I'm glad to post on this site.
The "Fully Balanced Bridge Amplifier" design in 1984 must mean the X-balanced amplifiers, such as AU-G99X, and after. If anyone takes close look at some Alpha 907 amplifiers on this site, you can see balanced input connectors. Some Sansui CD players have the balanced output, too. Fred, if you have time to look for the article, I'm glad to post it, too. I have been a computer tech guy for twenty years, so I like tech stuff!
Sincerely,
Isao
: Hello Isao:
: I just checked back to see that you have expanded the Site. I wanted to say you are doing a great job! As you know already I am a HUGE Sansui enthusiast.(For the others who might be interested, a list of the models I own are shown in the database section over at the Yahoo Sansui Group's Database section).
: Isao- I have a vast collection of hifi mags and I will be going through them all to index all the Sansui reviews and ads. I just obtained some more issues that I needed, one of which is the April 1985 issue of Audio which gives a very in depth review of the B-2301 and C-2301. Let it be noted that the B-2301 was, at 300 massive watts, the updated version of the equally powerful and mighty BA-5000.
: An interesting thing in the review is mentioned- that the Engineering team of S. Takahashi & S. Tanaka wrote a technical paper on amplifier design in the 'Audio Engineering Society' journal called "Fully Balanced Bridge amplifier"- June 1984, Vol 32, No 6, pages 415-421. I would like to find this publication. When time allows I may look for it in the college library. If anyone might obtain quicker access to it- please let me know.
