Why does Cary Audio keep discontinuing good amps?

"Because there clueless"

TBD but at leist they can sphell.

Lack of demand? when they introduce new products, it makes older ones unpopular.

"I understand planned obsolescence, but look at companies like Audio Research."

Arn't they the "leader of the pack" for this kind of thing?
I mean, how many preamp models have they done in the last 25 years, AND is there a point where they could have just stopped and still had an outstanding or maybe even better product - like the LS5- before departing into the "REF" series?

Two more reasons:
The Cary 120 amp needed a re-design because it runs too hot inside the chassis. The british press caught it, the american press went GA-GA over it.
The SLP-05 preamp has a Tube Engineering 101 mistake: the tube rectifier is mounted horizontally inside a slim chassis with very little ventilation. Rectifier failures are very common and expensive.
I believe that after Dennis left, they are clueless technically and from a marketing POV.

Cary lost me when they went into home theater.

There really hasn't been much of new product other than the 120S in like 10 years.

The Cary V12 was a great amp and cost 4k. Ahh, the days.
