  1. Well, I worked at WBTM in 1965-1967, 55 years ago. I don’t remember Alex Vardavas, he must have started after I graduated. Yes, a fellow classmate of mine sent me the obituary of Connie (the C in CEs). She was great. She let us students run a tab and pay when our parents sent us money. Is it true that Dan River Mills closed down? What do people do for jobs there these days?
  2. I went to school in Danville Virginia! Spent more than two years there getting an AA degree in electronics engineering at Danville Technical Institute (do they even still exist?). Lockheed Missile and Space Company hired me out of DTI, and paid me to get an EE, and eventually a master’s degree. DTI was on South Main Street, within walking distance of the city limit/ Carolina state line (and, in those years, walking distance for legal beer for eighteen year-olds in NC). Across S. Main from the campus was a restaurant called C.E.s. They had, what I recall to be, the best pizza I’ve ever had anywhere (but that might be nostalgia talking). I know that they closed after the owner, a wonderful lady named Connie, passed on in the ‘eighties. If you never got to experience Connie’s pizza, then you really missed out on something. While attending school, I worked as an announcer on both radio stations WBTM, and WYPR, and served on the engineering staff of WBTM (I already had my First Phone). Both stations were AM in those days and there were no FM stations or TV stations in Danville in those days, but WBTM’s lavish studio building was set up to serve as studios for AM, an FM outlet, and there was a TV studio in the building! Are they still operating in Danville? WYPR (called themselves “Whipper”) was a top-40 station, and I know they’re gone. When I was there, the city library was housed in an ancient building that was touted as the “Last White-House of the Confederacy”. That building was on Main Street north of where the street split into South and West Main. If you were heading south, it would have been on your left. Is that still there? Small world, is it not?
  3. Quite possibly. Most high-end amps either eschew overall negative feedback in favor of individual stage feedback, or they eliminate negative feedback altogether. The thing about negative feedback, is that it improves harmonic distortion when measured using sine waves. The problem is that sine waves are not music, and amplifiers behave quite differently with sine waves than they do with music, and it turns out that while feedback gives wonderfully low distortion specs when measured with test tones, it can actually cause other kinds of distortion when amplifying music. These are called slew-induced and transient intermodulation distortion, and it turns out that these are much more objectionable to the ear than simple harmonic distortion measured the traditional way. That’s why some of the best sounding amps, often don’t measure that way. For instance, the French Jadis tube amps have more than 2% THD (Total Harmonic Distortion) at rated power, yet the amps sound marvelous. Perhaps, this IS what Frank was talking about. Thanks for bringing that possibility to my attention.
  4. Well, I can’t argue with you there! Equipment like D’Augostino, dCS,and others have casework that is so fancy with it’s CNC machined front panels, knobs and switches that it surely must account for at least half of a unit’s selling price! One of the reasons why I admire equipment like Audio by Van Alstine, and Schiit is that all the money goes in the equipment’s guts, not in the casework bling. Where did you get the notion that Pass designs his equipment to “enable decent amounts of harmonic distortion”? I know one of his designers quite well, and he says that’s patent nonsense. One reason Pass uses class A in his amps is to reduce the distortions inherent in class A-B amps. Lots of designs use device “cookbook” circuits as points of departure for their designs. Always have. Nothing wrong with that at all. Tell me, Frank, where did you obtain your knowledge that allows you to second-guess a piece of equipment’s power supply designs? How do you know, for instance, that (A) the capacitors you replace willy-nilly are an improvement over the original design? Do you do the maths? (B) when your PS mods are finished, what improves? Voltage regulation? Current sourcing? Lower ripple? (C) How do you measure these improvements to the power supply; or do you just “guess” that the equipment sounds better? Frank, I have “read what you have done” for several years now. And just judging from what you have posted here, it doesn’t amount to a hill of beans. If you have, at one point or another, posted everything that you have done, then, that’s from where I have formed the opinion that your “method” cannot possibly enable the improvements in SQ that you have bragged about. Those speakers are never going to disappear, and that’s my point. I have no idea. I have never seen that movie. At first, I mixed it up with “Where Eagles Dare”, which I did see when it was in the theaters first run in ‘67 or’68. But I don’t remember much about it or its characters either, so, either way, your analogy is therefore lost on me, Frank. ??????????!!!!!!
  5. I have DSP room correction in my amplifier. I don’t notice much (if any) difference overall, but I will tell you where the technology was invaluable. I futzed and futzed over getting the subwoofers to integrate with my Martin Logan’s. There are so many variables; sub placement, crossover frequency, level matching, etc. It’s a nightmare and they never sounded right. My amp has outputs for two self-powered subwoofers and I have two subwoofers. The outputs, if you choose to activate them, are in the DSP circuit, and will be adjusted along with the main output. So, I set the crossover frequency for the subs to 80 Hz, positioned the subs where they were as inconspicuous as possible, and I cranked each of the powered sub’s level control all the way up. Then using the calibration microphone that came with the amp, I ran the calibration program. I told the amp that I was running two powered subs, and I moved the microphone around as the program instructed. When the calibration was complete, the subs suddenly disappeared! I could no longer tell where the main speakers stopped and the subs took over. All I noticed was that I now had seamless bass down into the twenties. I’d say for that reason alone, DSP room correction is well worth the effort. In fact, I’d go so far as to say, don’t do subwoofers without it!
  6. I like what actor George Sanders said when a reporter asked him how he felt after his divorce from Zsa Zsa: “Like a squeezed lemon.” Never saw the appeal of either of the Gabor sisters, Zsa Zsa or Eva.
  7. Not really. I think that divorce should be equitable. Former spouses should be able to shake hands and walk away, with each taking 100% of what they owned going in and 50% of shared assets. Alimony would not exist, but of course, child support would also be 50/50. That’s only fair.
  8. Nah, my thoughts are much too politically incorrect. Heaven forbid that I exercise my Constitutional First Amendment Right of free speech! 😉
  9. It is if you’re a modern re-incarnation of Wallace Whimple. These guys I know are that. They’re not happy, they’re afraid of their wives, and they are more afraid of the California court system which, if they try to divorce the shrews, will give her everything the man has ever owned and anything he would be likely to own in the future. I don’t blame them there, the CA divorce courts are brutal to guys in a divorce. I shudder just to think of it!
  10. In our modern society, that seems to be more likely the case than not. I have a number of married friends, and in NONE of them is the husband the head of the household. One of my friends even admits it. “I’m not management at my house,” he says. “I’m merely the hired help. My pay goes into her account, she decides where to spend it, she pays the bills, if I need money, I have to beg for it, but she doesn’t ask me when she wants to buy something. I’m just here to fix broken things and chauffeur members of the family around”. If I were this guy, I certainly wouldn’t admit to being in that position even if I were. But I wouldn’t be. Were I stupid enough to commit matrimony (and I’m not), I would run my marriage the same way that I have handled all of my female relationships. They get three strikes. After the third strike all my former girlfriends were OUT. I would do the same in a marriage. Piss me off three times and it’s ADIOS mi’lady!
  11. Truer words were never spoken. In engineering school I took calculus, statistics, solid geometry and several other advanced mathematics classes that I slept through, but somehow managed to pass. In my entire career as an electronics engineer doing design work, I have never had occasion to use anything more advanced than high-school algebra!
  12. Actually it is very representative of the vast difference between men and women. Men are logical, “women are irrational, that’s all there is to that! Their heads are full of cotton, hay, and rags!”* But then, what do I know? I don’t trust the fair sex** and I loathe the idea of matrimony. “Let them (other guys) buy those wedding bands for those anxious little hands... I will never let a woman in my life!**🧐 ** “Women, even the best of them, are not to be trusted...” Sherlock Holmes * *** George Bernard Shaw by way of Alan J. Lerner and Frederick Lowe
