Ο γερο-Περπατητής τον είχε διαλέξει για διάδοχό του στην Quad - κι αυτός αρνήθηκε!!! :mad:

“So many people don’t account for all of the things that could be changing as a result of the intended change they thought they were making” “A natural, balanced performance, capturing the original artistic intent, across the spectrum of all types of music” “There is no reality”. Ανάλυση, σύνθεση, αφαίρεση. Συγκλονιστικά απλός. Τα CR1 τα ονειρεύομαι πιο συχνά κι από τη Jessica Alba.

"You have a hierarchy: a mathematician, a physicist (which is a failed mathematician), and an engineer (which is a failed physicist)."

Μα τι λέει; Ελπίζω να μην αναφέρεται σε audio applications ο ασχετίδης...
Εκεί τα πράγματα είναι διαφορετικά:

You have a hierarchy: an experienced, golden-eared audiophile, a mathematician (which is an inexperienced, bronze-at-best-eared audiophile), a physicist (which is a failed mathematician), and an engineer (which is a failed physicist).

:cool:

Κι αυτή η ιστορία με τα take it easy listening tests μου θύμισε εκείνο το ωραίο του Άκη Πάνου: «Ήταν ο καλύτερος παραγωγός. Την ώρα της ηχογράφησης σηκωνόταν και πήγαινε για καφέ»!

"After studying physics and acoustics at university, I went to do research with Malcolm Hawksford"

Χεχε, προφανώς.


"Fincham joined KEF in 1968, and was instrumental in the development of KEF’s technical expertise throughout the 1970s and ’80s ... he needed somebody in his research group and asked me to join KEF in a pure research capacity ... I joined, and eventually became Chief Engineer. I don’t know how many mistakes I made along the way, but I was there 11 years.

KEF was a wonderful place -- a Speaker University, really. We had access to everybody: Stanley Lipschitz and John Vanderkooy, Peter Walker of Quad, Greg Mackie from Celestion, Neville Thiele, Dick Small -- all these wonderful people. We used to meet at Audio Engineering Society lectures and conventions. They would come and give private lectures at KEF, and then Dick Small joined KEF to become head of research. With these relationships and access, if you had questions about anything, you could just pick up the phone and call. Peter Walker was wonderful; we would meet once a month in London at the AES lecture series and all go out for dinner afterwards. I’d say to Peter, “I’ve got this problem about blah blah blah blah,” and he says, “I’ll think about it.” I always knew -- it could be days later -- the phone would ring, and then, “It’s Peter here, I was thinking about what you said . . .” and out would spill just this wonderfully elegant treatise on what you’d been doing. With Peter Baxendall, same thing. We used him as a consult. It was fantastic training. I think that a problem with a lot of companies these days is the absence of the opportunity to work with all these people to learn the real engineering behind what you are doing. Today it is too often just experimentation through trial and error, or redoing slightly what someone may have done somewhere else.

Τον Baxandall τον γράφει λάθος - και έχει και πολύ αστείο όνομα ("He arrived, bags and all ...").


"I don’t think people realize just how thorough an understanding of the fundamentals of acoustics and electroacoustics someone like Peter Walker had. People like Walker and Baxendall :rolleyes: can turn their thinking around and give you an elegant, reasoned answer to so many questions. Walker often said that if you needed more than A-level maths to answer a question, you are thinking about it in the wrong way."

Ο Walker τα επρέσβευε αυτά, όχι εγώ, αλλά μια και κάποιος -που δεν έχει γράψει ποτέ μισή λέξη της προκοπής- μας ανέμιζε κάτι πτυχία πρόφατα ... ;)


"If you look at a lot of the research that Floyd Toole does -- what do loudspeakers sound like, and what choices do people make when they listen to loudspeakers -- he hails from that old school: “I’ve done the research, I’ve looked at off-axis performance, I’ve looked at frequency response, and most of the time, I can rank speakers based upon the measurements of them. I think we know sufficiently about the measurements to rank them with a trained listening panel.” That approach is anathema to a lot of the subjective people. While there is a lot of truth in Toole’s position, is it the whole truth?"

"It confirmed a lot of beliefs that ceiling reflections are one of the worst. Sidewall reflections can be good, adding to a sense of spaciousness, if the stereo speaker possesses well-controlled directivity. This same sidewall phenomenon happens in concert halls, on a different scale. The tall, narrow, long concert halls -- traditional ones -- were always the best halls. Sidewall reflections are lower-correlation than ceiling or floor, so they add spaciousness. Correlated signals, by contrast, add coloration."

Not enough.

Στην αρχή συνοψίζει την ιστορία της TAD και στη συνέχεια έχει μερικές ενδιαφέρουσες, αν και όχι τόσο πρωτότυπες, παρατηρήσεις για τα ηλεκτροστατικά, τα ταινίας, τους τρόπους φόρτισης στα μπάσσα, τις αυτοαποκαλούμενες "γραμμές μεταφοράς" και άλλα.
