To understand why
Panasonic does not design/market higher end audio products you need to back into the 80s' when Matsushita (parent Japanese company) marketed 2 brands of audio products. The 1st brand was Technics which was a very extensive brand that dominated receivers, components, direct drive turntables and cassette tape decks. The 2nd brand was Panasonic which was very strong in music systems, integrated components but of lower power/quality.
Somewhere within the higher ranks of Matsushita, a brilliant decision was concluded...
That the Panasonic brand could provide all
of the sale and profits,
that had been delivered by the sales of the quality audio components marketed under the brand of Technics. Then they would only have the marketing expenses of one brand and that the consumer would still buy the product under either Technics or Pansonic brand....
Sounded good but it backfired big time..
Virtually overnite once this announcement was made, any dealer or consumer having a Technics products instantly found that it had dropped significantly in $ value. So the dealer marketing network responded by dumping all of their unsold Technics products/stock... When the dust finally settled corporate Matsushita, realized too late that they destroyed the Technics brand while throwing away tens of $ millions..
Later when they tried to reverse their original decision and reintroduce the Technics brands/products the market turned their back as they didn't want to get burnt again.. They did sell a lot of Technics Direct Drive turntables later on but for the most part, Matsushita has decided to just stay with the Panasonic brand..
