Audio Research Sold

@ivanj;
Is this true of current era ARC such as my Ref 150 SE too? IIRC, an arcing tube will take out one resistor that is fairly easy to replace. It is also my understanding that ARC refuses to resort to fail-safe protection based on their belief that all such devices degrade sound quality. From what I can see when I remove the cover to check bias, the circuit boards are high quality single layer and the circuit is fairly simple and the paths are short-so much so that getting access to the bias pots is not easy due to the tubes being so close. 
I already addressed the questionable path McIntosh has taken above. Your comments don't surprise me in the least. I am cautiously optimistic that the new ownership will be a good thing for the future of ARC. 
I am a former bicycle racer that still eats and breathes all things cycling. For every Pinarello remaining at the forefront of engineering innovation, there are four Masi's that have completely sold out their once iconic status for the sake of mass-marketing and peddling mediocrity, 

There's so much utter horse shite spread on this Board (in general) and in this thread in particular that it makes my head explode. In order to not offend specific people, I will not cite examples. 
I do agree that McIntosh has diluted it's brand and thank goodness ARC won't be exposed to the same. ARC from day one has been a hit and miss company, some great products and some duds. In the last ten years things had improved. Hopefully that will continue. 

Every company that’s ever produced a product for sale has had hit or misses.

No, many companies never succeed in making a "hit". But perhaps we are talking past each other. I am talking about iconic stand-the-test-of-time products. 
There are countless companies that have risen to the top and then disappeared or lost all of their reputation due to changes of ownership or the death of the founder. In fact, it is the natural course of things and the exceptions are few and far between. 
I think this is a now a pivotal moment for ARC. IMHO, the loss of Ward Fiebiger was huge and since his death, the product launches have been more about style rather than innovation. Saying that "amplifier design is limited to only so many circuit designs and is not rocket science" ignores the fact that incremental changes in parts quality continue to occur. With each change in parts, there is an art to coaxing out the best possible sound. It takes a very rare corporate identity or corporate leader to make that pursuit the absolute number one priority. 
ARC's prices have always been high but not at the crazy high level of some other product lines. If it is true that ARC has not been very profitable lately, it would be understandable given the level of hand assembly and QC right here in the USA by mostly long-standing employees.
