Little Vinyl Rant

Bubba, that pic there mimics my setup in 1975. Except for the groundwellers they were a Magnavox box full of 15" woof and 12" horn. All 4 being pushed by a healthy Spec 2. Pretty darn good and portable as hell as I was moving all over the state chasing the oil boom.

As I mentioned thats an older pic. I dont have the Series VI's anymore, and the Bose power amp is no longer in the mix. They were replaced with V's and the Crown power amp.
 
On ZZ Top---Tres Hombres and Eliminator, saw them in Casper once--Awesome.
 
It's sometimes tough to hold too tight to the topic, because in light of trying to help a member in a specific query or observation, we try to steer the conversation to our own personal experiences. I would much rather hear about personal experiences related to audio because it's not the same as reading a review made in a magazine where you are parroting some one else's view or recommendations. I have made references, as recently as the other day on the Oppo BDP-105 thread, but only to supply technical details.

I hope that Joe isn't offended by any seemingly off-topic discussion on this thread, but should he be, we owe him an apology and decide on whether to acknowledge when posts go off skew and correct it.

Gentlemen, off topic has yielded some gems in this forum. If you have to wait or try and remember what crossed your mind in a thread you didn't feel it was ok to post in, it'd be a shame to lose a piece of tactical levity, or brilliant insight. I will now try to generalize a mode of behavior for which we have blessedly not had to do, nor do we have to now, IF A MAJORITY OF THE POSTERS HERE FEEL OFF_TOPIC IS TABOO< LET IT BE KNOWN HERE_______


I will let this post kinda stew here and then repost it as a separate thread. Been awhile since we discussed it. The official, unofficial stand was if the OP didsn't like the way things were going he could let that be known and the unobjectionable behavior would cease......or not depending on whether the offending posters thought he was serious......


A perfect example is this thread, Joe has always been a good sport, and the speaker placement/dynamics discussion is topnotch. We can prune and move all relevant speaker posts to a new thread but it takes the ebb and flow out of the discussions....what do you guys think???

Thanks, I think?

I'm for off topic unless the OP wishes otherwise, for exactly the reasons you cite above- here and further up. How about asking the OP (not this particular OP) to declare a preference a the outset (subject to change at his/ her whim) if they have one, and let things wander otherwise? That's where we are now, right?

In my view, the stripper/ hooker stuff really doesn't belong (also my fault) but since this is an audio board, audio related stuff should be fair game, again, unless the OP wishes otherwise. Thank goodness no one took up the political aspects of what I said. That'll ruin a thread quicker than shit. Hey, I enjoy a good (or strained for that matter) metaphor, what can I say?

It's all related, and I think we can all benefit from these meanderings.

If any of what I wrote is deemed helpful, then it's a good thing we wander. How long would it have been before I would have had another, natural opportunity for this to have come up? I sure wouldn't have started a "look what I know" thread. Might be sooner if I went to the appropriate section, but I don't.

OTOH, it's maddening at times to find stuff on this board due to the OT nature of things. So, if you're not part of the initial conversation, it's harder to get involved.

OK, excellent. And I'm not against a true single point thread, just hate to hobble the discussion in any way, but........I'm just like that.




within 50mS of the direct sound (Haas effect), Zach, I had read somewhere that , that effect started at 15ms and ended about 50ms. Not being picky I just remember a range, not a specific number.

I don't recall that, but it's been a while, so let me take a minute to consult the acoustics bible- The Master Handbook of Acoustics.

"In the 5-35mS region, the echo level has to be 10dB higher than the direct sound to be discernible as an echo... For delays of 50-100 mS, reflections are perceived as discrete echos." Mr. Everest also mentions other specifications of the integration time, etc. So, looks like it depends on the relative SPL level and the time delta. There's a graph showing all of this as well.

This is just what I meant by helping all of us- I wouldn't have looked back at this reference work without this conversation and would have been stuck with my 10 or so year old memory of it, which comes up short as it turns out. I had forgotten about the dependance on relative SPL.

I had bought a pickup load of bBPC at a ranch sale awhile ago, some good stuff but mostly junk, and on the way out with the ladt armload I stumbled over this book. "Sound Reinforcement Handbook". After reading it I would take all that stuff back to keep this book. An exhaustive treatise on that subject that went from theory to application, then real world consequences. The other pic is one of my daily references.

I'll post the table of contents, if someone has an interest in any particular subject I believe I can scan and post it.
 
Hey this is ALL GOOD guys. It's relevant and fun. After all, the biggest recent change was the speakers themselves, and taming these was defineatly needed. As said, sometimes you need to step away from an issue to get some clarity!

The other thing is to keep in check how seriously we take ourselves, and I'm really referring to myself. You know the story, some guy goes into see a doctor, shows him that it hurts when he twists a body part in some overly contorted way...doctor says, Don't do that! Problem solved. Most certainly I've been guilty, of not that specific example, but relatively speaking about all sorts of things. Defineatly in my approach to my own personal audio system(s).
 
You come up with many great analogies, Joe. I am as fussy as you are regarding what I want from my stereo system.

Nando.
 
You said you were wrong about your approach to your audio system. Hence my question.

Well. I did in fact attack my listening fatigue complaints in my apartment by changing a great deal of things, within the system, to make a particular pair of speakers sound easier on my ears. However the reality was more that they were not the right speakers to begin with. Thus, I was abandoning certain aspects of fidelity from a playback "purity" perspective for something more "colored" and tonally soothing. Is it wrong? Well, it's what I was doing. The problem with doing things this way is fixing a mess with something else that is proportionally an equivalent mess in the opposite direction. So... What happens then when you change a component within a system built in such a way? You can end up worse off with a new component, even if it is one of truly higher fidelity! Now THAT, is the ugly side of what "synergy" can be.
Tossing Vinyl playback in as a source upped the anti on the problem scale by a factor of 2.
 
No Lee, I looked it up: Piezoelectric Force Microscopy effect.

I've got the amp book, and a couple of Mr. Sloan's other books- been a long time since I read that. The other I don't have, since it looked like most or all of what's in it is in books I already have. It does look like a solid reference, though. Might pick it up later. I'm behind on my recreational, technical reading already.
