1. In some ways, judging a company by past products is a good thing. What is the company’s reputation for sound? For innovation? For reliability and service? But there is one big downside and that is an inability to move past weaknesses of older designs. One example is the brightness of older Wilson models that used the inverted dome tweeter. I still get reactions from people when I mention my Alexia Vs….”oh Lee, Wilsons are so bright to my ears and very analytical sounding.” Really? Have you been to a stereo store in twenty years? Another example is tube amps. “I don’t like the missing bass on tube amps.” Really? Have you heard modern tube amps? Audio Research Reference? CAT? Conversely, “I think tubes have better midrange than solid state. Solid state has poor midrange.” Really? Have you heard the Class Pass Labs amps lately? It’s hard to put old prejudices aside but I think we must. Gear has become much better recently and certainly over time. The Rossini Apex is WAY better than the original Rossini. The new Magicos are way better than before. High end audio is producing super high quality, very advanced, aerospace-grade tech and it’s making for eargasms.
A few observations ...
I think you realize you are talking your book; its your job, so understandable. Very rarely do publications cover products no longer in production. An emphasis on the new is in your dna.
I don't think that changes the points you raise per se.
History is inescapable and so is memory. That products leave poor impressions in people's minds is experienced based and quite possibly those products were extolled by publications at one point. And those reviews are still out there to be read. We read about the new but such readings rarely point out past weaknesses as weaknesses overcome.
You say it is hard to put aside old prejudices. Perhaps that is true. Nonetheless, those "prejudices" (assessments really) were built on experience. Since you like sports aphorisms, I'll give you another one that goes out to manufacturers, this time from Redskins coach George Allen: "The future is now." What products do today will echo forward. It took the 20th Century to arrive for Audio Research to start moving away from the tin-foil-in-your- mouth sound of their amplifiers in the 1980s and 90s.
You observe "1. Audiophiles judge a new product by past products a company has had." There you talk about things like innovation, reliability and service -- considerations about a company. Reviews judge new products against past products but rarely talk about reliability and service from the company.
Many/most manufacturers need to keep their name in the press so we get continual Mark 2s and Version 3s. In an effort "to be new" sonics get changed, and while new sonics may have entertaining effects they can lead away from the sound of live acoustic music. Consider the continued addition of signal filtering in certain lines of cables. The reviewing community consistently compares the new Y to the old X, as in your Rossini example, which yields constant churn and constantly shifting references. Although flawed in how he implemented it, Harry Pearson put a reference stake in the ground that, in theory, did not change.
The used market is huge. I"m waiting for a publication that reviews past products and compares them to current products. There are many people and publications that engrave in stone: New is Better. Talk of 'vintage' this and that, particularly vintage sound does a disservice to buyers. Pity the manufacturer who gets it right the first time. Once again (no doubt to the annoyance of some) I'll draw on Vladimir Lamm. He made so few updates to his designs -- designs based on extensive testing with real people -- because human hearing has hardly changed over time.
I tend to agree with you that "materials, parts quality, and engineering approaches are ever getting better". But it does not follow from that alone that sound is getting better. Whether such changes alone lead to the somewhat presumptuous "rightfully earned time in the spotlight" will be up to the consumer.
