I have always liked trivia & since audio is my favorite hobby here goes. The emphasis on this trivia challenge is "interest" as opposed to "technical" since these are to be fun not give someone a headache. I try not to become obsessed by my hobby like some sports fanatics who can recite the entire rosters of every baseball team and the players batting averages, but I have picked up some interesting trivia along the way. You can write the answers down on a piece of paper for yourself to see how many you got right, when I post the answers on this same thread on August 18th. Don't post your answers on here, that would give it away & ruin it for everyone. Looking stuff up on the net is cheating.

Heres the scale: 10 to 13 correct=Good
14 to 18 correct=Very Good
19 to Perfect ( Exceptional)

Q1. What company came out with an audio product called the POD. Decades before iPhones & iPods. It has nothing to do with phones.

Q2. A.J. Van den Hul, inventor of the stylus shape & famous cartridge designer had/has a phono cartridge upgrade/retipping service for any brand of cartridge. What according to an interview, was the only brand/model cartridge he wouldn't upgrade with a new stylus because he felt it was a good design as it is? It was not one of his own Van den Hul cartridges.

Q3. What was the first half speed master LP that was released by an audiophile LP label, simultaneously with the regular pressing from the groups regular non audiophile specialist label?

Q4. What lp, as a gimmick, came with a conductors "stick/wand" attached to it? Obviously a Classical title.

Q5. Name the speaker company that came out with a speaker model called the "Clyde."

Q6. Name the two opera singers who went on to become very famous audio designers? Both of their commonly referred to names have 3 letters in their first name & 5 letters in their last name.

Q7. What major high end manufacturer coined its name from the name of a "being" in an old famous Science Fiction movie?

Q8. Name the famous Jazz LP which had speed/pitch variation difficulties, which devoted collectors try to get both versions. If there is more than one example of this; the more famous LP is the one we are looking for

Q9. Name the famous classic rock LP whose Dolby noise reduction broke down in the studio while being recorded. It was later released as a half speed master audiophile LP and was also the audiophile labels first rock title to go out of print.

Q10. What company once came out with a product called the Cartridge Coupler, which dramatically improved everything from tracking to transient response?

Q11. What famous conductor had a feminine sounding first name which a major record company chose to conduct for its last LP to be released on its most famous series of records, before switching to a different record cutting process?

Q12. What high end manufacturer came out with a transformerless amplifier called the Panthere?

Q13. What audio amplifier company came out with a series of amps whose model names were based on an old famous foreign made "monster" movie?

Q14. What famous audio designer known for his colorful wardrobe and hats had a collection taken up by a major US audio publication, asking readers to send donations to help him pay for a needed medical procedure involving his cancer?

Q15. What came first in the US: the introduction of the cassette deck or the first all solid state stereo amplifier?

Q16. What came first: the end of the Korean war or the first available "Stereo" releases of music in the US?

Q17. Which fiery hot tempered "golden age" conductor was known for throwing his baton at musicians who he thought were not playing well. Hint: his first name was a nickname that US military personnel often called their prisoners.

Q18. In what decade was the first electrostatic transducer put into operation?

Q19. When navigating a friction producing record groove, stylus tip temperatures can reach temperatures up to: A.400 degrees F. B.800 degrees F. Or C. Thousands of degrees F ?

Q20. On one of the old black and white Danny Thomas comedy sitcoms there is a piece of audio gear prominently displayed in middle of the living room in virtually every episode. What make & model of gear is it? This is the one question that I am not 100% sure of myself.

Q21. The phonograph was Thomas Edison's self proclaimed favorite invention. How long did it take him to get a workable example from start to finish?

Q22.. This is the last and in my opinion hardest question. A homophone is a word that sounds & is pronounced exactly like another word but has a different spelling and meaning. Name an obscure speaker company from the 1970s,( not that obscure; they had some reviews), that is a homophone of something that this trivia challenge has countless examples of?

As I say I like trivia and had enough questions written down for 3 or 4 of these. Maybe there will be another in upcoming months. When I post the answers to the questions, feel free to say how many you got correct (without cheating) and other comments. Thanks.

Try my, somewhat shorter, easier, and more tech centric, quiz from 2002:

https://forum.audiogon.com/discussions/ ... dio%2Bquiz

I liked yours very much, though I believe when you reveal the answers that there are multiple answers to some of the questions. Thank you!

So you are like Leif Erickson (spelling?) and I am like Columbus. Maybe there were even quizmasters on these type of forums before either of us.
I enjoyed your quiz and embarrassingly I only got about half of them right. The tube questions I didn't't know, I didn't know the Sanken transistor one, even though I have been through some Luxman equipment, Primiare sounded Italian to me, even though at one time I read up on their equipment & would have known it was made in Denmark if my memory would have been fresher. The Dayton Wright electrostatics I did not know had a tweeter like that. I knew the part about the bag.
Mike Wright came out with a line of dynamic speakers in the late 1970's called Watson Labs which also used a bag. Hexaflouride gas he used in the bass modules. Tightest most musical bass ever. The dipole midrange and tweeter panels on top easily outperformed stuff like Dahlquist DQ10, Shahinian etc. They were probably the best overall dynamic speakers on the market at the time, but being the perfectionist he was, he discontinued the line when Audax stopped making the tweeter his speakers were designed to use. There are some photos on the net of the top of the line model 10 and some write ups.
Dayton Wright speakers are rare. When you punch in the company name on ebay, all you usually get is old pictures of Orville & Wilbur "WRIGHT" who were from "DAYTON" Ohio.
After I put the quiz on, I realized it was harder than I thought. Regardless of what I wrote, if people get more than 5 questions right; they've done pretty well. The hint on the question about the conductor who was known to sometimes throw his baton; referred to what US soldiers sometimes called prisoners in WW II, which I didn't specify. The hint in the last question, which is my favorite; probably won't help at all unless you ever heard of the speaker brand. A picture of the speaker was on the cover of an old issue of Guide To Stereo & Tape Equipment to be reviewed and the name sounds like a famous audio electronics company and a famous speaker company merged. In fact when seeing the issue on my coffee table, a relative of mine thought that and asked me if the companies joined forces. Which they didn't.

Yes, your test is hard, Chris. May I call you Chris? Feel free to call me Leif. Or ask me to Leif. Whatever works.

I am very confident in 9 of my answers to your quiz. And I have taken a stab at a handful more. Doubtful that I will answer 50% without a tail wind for my ships and a good deal of luck.

I got one of your opera singing designers right away, and am racking my brain for the other. Can I get 1/2 point, LOL?

Multiple choice seems the way to go when dealing with audio hobbyists....well, this audio hobbyist anyway.

The other question that could have multiple answers is the speed variation on the tape a famous LP was made from. That could have happened many times, so I asked for the most famous example of this.
I have some very interesting direct knowledge from some of the best designers from the late 1970's early 80's. When you called the companies back then, they sometimes were actually the ones who answered the phone at times. Boy have things changed.
If I do more, I am going to include a few bonus questions. Stuff that I myself always wondered about and really want to know, about audio & music. Of course I will have to verify the correct answer to the ones that I want to know the answers to myself.

I definitely will post the answers under this thread on Saturday, August 18th 2018. Don't you just hate some of those threads in the other forums where someone promises to do an interesting comparison between different pieces of equipment and everybody is writing back & forth in excited anticipation and the conversations are 10 pages long and everybody's waiting & then "NOTHING" at all.
I will add a bonus question NOW, whose answer will also be revealed Saturday.

BONUS QUESTION: Remember the old Gong Show hosted by Chuck Barris? There was a comic who regularly came on the show with a brown paper bag over his head, and was known as The Unknown Comic. Which audio company featured him, pictured in one of their ads for their audio equipment?

When putting together the quiz, I had some other questions written in ultra shorthand, that my mind couldn't figure out. I guess my shorthand was too short. Now that my memory came back on them, I could use the questions in the future if I do another quiz
One of the questions concerned Duke Ellingtons favorite speaker, which he owned and was designed by a famous audio guy that was totally associated with designing amps and never speakers.Maybe the first "major" amplifier designer who started his career by designing speakers ?? You wouldn't' believe who was also involved with the project. Like a who's who of soon to be famous audio designers.
I also would like to ask or interject into the next possible quiz, some things I once knew but forgot. One involves the composer Igor Stravinsky. Another famous composer once said or wrote, that in his estimation, Stravinsky never had a good musical idea in his entire life. I used to know who that was but forgot. Stravinsky composed music that was really unique ano strange at times, and even though I like it, it is not hard to picture someone who wouldn't care for it in the least.

Another thing I always wanted to know was exactly who fashioned the first cone driver? Maybe some private experimenter in a garage somewhere. For years and years conventional speakers used paper cone drivers. Some of the old timers just have it in their minds that paper is what drivers swould be made of; but the guy who made the first cone speaker most likely didn't try out dozens of different materials, listen carefully to each one and then decide on paper as the ultimate material. He probably just fished for something that he knew should be lightweight and thought of paper, since it was handy and abundant. In retrospect, probably the best thing about paper as a driver material is that it doesn't' add much of its own character to the sound, low in coloration. Most speakers above $1,000 use something other than paper for its drivers, although there could be a trend back to treated paper cone in some circles. It might be more, how the use of the materials are actually carried out in the design.

In 1925 Kellogg & Rice at GE got credit for inventing the first commercially usable cone speaker, but there are reports that people were experimenting and getting paper to electrically vibrate and make sounds well before that.

Hard to believe that people have been listening to cone speakers for around 100 years. AR came out with dome drivers in its model 3A in the 1960's. If you had an older model 3 you got a letter from Acoustic Research in the mail informing you of the new driver and an offer to have your cone driver upgraded for a reasonable cost. The way I understand it, you had to send your very heavy speakers to Acoustic Research for the fitting. Oh well, the postage wasn't too bad back then. To mail a letter cost less than 5 cents if I recall right.
I will post answers 1 through 11 of the trivia challenge quiz Tonight before 10 pm EST. I will post the second half of the questions 12 -22 daytime tomorrow. Let us all know how many you got right, your favorite questions and other comments you may have.

Correction on the above: it was the AR 3 not the 3A which is generally credited to have implemented dome drivers.

Here are the answers for questions 1-11 of The Audio Trivia Challenge Quiz. Due to time considerations I will post answers to the second half, 12-22 tomorrow, as I promised.

A1. The EON POD was a vintage 1980's record LP clamp. Inexpensive, lightweight & effective, it tightened transients and all kind of other good things.Once you got used to it you couldn't listen without it. Still use mine. It slipped over the spindle, and the bottom section, (which resembled lunar module feet), pressed down against the record label while the top part tightened its grip on the spindle. Clever & ingenious. Rare.

A2. The one cartridge that Van den hul would not modify because he felt it was a good design & didn't need messing with, was the original DENON 103. I believe it has a simple conical stylus ! Wow.

A3. The Police album Ghosts In The Machine was released by the audiophile label, Nautilus simultaneously with its non audiophile release on its own major record label. A first.

A4. The LP that came with a conductors wand attached diagonally right across the front of the record cover was the golden age RCA LP "Music For Frustrated Conductors." Various conductors & music from Carmen, Victory At Sea, The Mexican Hat Dance etc.

A5. Castle Acoustics, a UK speaker company many years ago came out with a highly rated speaker called the "CLYDE".

A6. Famous cartridge designer Joe Grado was an opera singer turned audio designer.Another one was Sid Smith who designed for Marantz most notably and was involved with the Marantz 10b and classic model 7 tube preamp. Both he and Grado lived in the same general NY/NJ area. In case there were others (its a big world), I asked for two names with 3 letters (first name) & 5 letters (last name).

A7. Krell was named after the name of a creature being from a golden age Sci-Fi movie.

A9. The 1970's album that during its studio recording session had its noise reduction system go out & become inoperable was Katy Lied by Steely Dan. It was planned to be a great sonic showcase, before the technical difficulties according to an old High Fidelity magazine interview. It was later released by Mobile Fidelity as one of their fairly early half speed Original Master Recordings and was their first rock title to go out of print.

A10. The Cartridge Coupler was a tweak item marketed around 1983 by The Mod Squad. It was a slim piece that fit between the top of your cartridge and the headshell. The bottom part of it fit flush with the top of your cartridges shell, the top of it contacted the underside of your headshell via 3 tiny sub bb size hollow balls of an unknown material. The Mod Squad invented tip toe speakers to be placed in tripods (3) configuration under your speakers. There were tripods tiptoe couplers for your cartridge. The improvement was immediately noticeable & dramatic with my MC cartridge. Faster, cleaner,clearer, more open with much better tracking. If too much torque was used tightening the cartridge screws the little balls of the cartridge Coupler could get crushed in, ruining it.

A11. Rene' Leibowitz was the conductor that RCA chose to conduct POWER OF THE ORCHESTRA. It's last "true" Living Stereo LP before going over to the Dynagroove record cutting process, which many audiophiles disapproved of because of its sound.

The answers to the remaining 11 questions will be tomorrow.I gave these a day early. Also my shorthand prevented me from making out what Q8 was. Will take a look and add that on in a minute.

The answer to Question 8 about the record with speed/pitch variations is Kind Of Blue by Miles Davis. The best selling jazz album of all time.

Well, I’m at 6.5 so far. And teach, it’s “Ghost In The Machine.” Singular, not plural. That one stumped me, as did Leibovitz, Sid Smith and the baton wonder, and the DL103 was a total shock. Thanks for the fantastic info. Keep it coming.
