It's unavoidable that Pioneer will get outsized recognition and nostalgia just because they sold so much that they dominated the market. I'm objective enough to acknowledge that, and even state my respect for some of their gear that I've personally had in my collection.
What I don't get is the guys who will bag on Sansui or Kenwood or any of the other smaller outfits who made some top shelf gear just as a knee-jerk response to anyone whose preference they don't share.
Just one's ego getting in the way I suppose, but it comes off as juvenile "my dad can whup your dad" posturing. To come into the Exclsuively Sansui forum and post:
Never had any interest in Sansui gear back in the day, always considered an inferior brand by most back then so I can somewhat see the articles point.
Also never had any interest in receivers, still bottom of the tier in performance so who cares.
Is like being at the park on a sunny spring day and randomly telling someone their dog is ugly. Unless the point is specifically to inflame ala the daytime TV talk shows or radio shock jocks of the 80's and 90's, then mission accomplished.
It is self evident - given the following and prices commanded on resale - that Sansui was high quality gear, and even their most modest models - while often lacking in features - were still built to a standard that represented the company well and have often lasted just as long as their fancier counterparts. Moreover, Sansui was an engineering-centric outfit. They poured incredible amounts of money and expertise into furthering the art and science of sound reproduction, most notably in amplifiers.
They had some missteps, too. They committed to quad in a huge way and had the most advanced and best performing of the matrixed 4 channel formats. Regrettably, the market gave it a big yawn so it was largely a wasted effort, much to their economic detriment.
Then there were the big wins: Super Feedforward, X-Balanced, ultra high-speed and high bandwith output devices, industry leading recognition of total intermodulation distortion and how to measure and reduce it. So too the attention to detail and quality evident in the AU-X1/TU-X1, B/C-2301 and the late stage alphas. All those were far beyond anything to be expected from a solidly mid-fi maker, even if that is where most lf their efforts were concentrated.
