If it's made in West Korea, then you KNOW it has to be good.

Damn some of that sh!t looks scary.
WOW, that is quite the soldering iron he has there, I'll bet he stole it from his dad who used it for wood burning(carving) when he was a kid. I wonder if he uses solder paste and plumbing solder too. DOn't laugh, I just repaired a video card for this kid who tryed to solder back on some caps that he had wacked off and he used plumbing solder, what a bitch to get off too.
Drag, you want nice tight bass, stop using that crappy Xover and 10 feet of speaker wire and you might start hearing some tight bass.
lexx21, I see you still have some learning to do about electronics too.

ROFLMAO! Actually I have been doing electronics for the past 30 years. I even have a degree in it specializing in rf transmission. Ahh.. the days of klystrons, magnetrons, and possible sterility 
As a kid I would go dumpster diving at tv repair shops for components. Ham fests were a blast and frequently I would be dragging out a 150 pound scope (I only weighted 130, so it was quite a sight). I even have a permanent scar on my thumb in the shape of a Motorola "M" logo. I refuse to go into detail on how that happened but I will say that I melted a perfectly good breadboard (I was 15 at the time). Every now and then I will design and build something, but it seems that the older I get the less time I have to do things like that.
I suppose my point was that when it comes to home audio, you have to be a realist. The old adage that if it sounds too good to be true, it probably is. When you have "reviews" claiming a product such as the metal embedded cloth will make your cd player sound better simply by laying it inside, I have to call BS on that sort of thing. If you want to shield part of your circuit, house it in a metal enclosure an have that enclosure soldered to the ground plane.
Yeah, you can have caps go bad. It happens. You can have transistors and chips go bad. It happens. You can blow a diode. God forbid if you owned one of the Sansui integrated dc coupled amps back in the 80's. Turn it up too loud and it would blow the amp and fry everything back to the power supply. It happens and I repaired tons of those things. After running a circuit and heating a resistor it will change value over time. It happens. I'm in no way saying that parts do not go bad. What I am saying is this... the way they make it sound is that by running it for hours on end you are going to make it sound better, which is crap. Or that by using $100/ft cable, your stereo is going to sound better (utter bull crap).
The pics that were posted of that kids projects were a good example of someone who had more money than sense (and a serious lack of soldering skills).

A resister is going to be accurate to withing it's spec of 5%, 10%, etc.. |
I bought a decent pair of new speakers , Quad 22L's at about $1K a pair. Sounded absolutely awful for the first 100 hours or so. Then smoothed out and "openend up". you can believe what you like but something changes in eletronic devices as they go from brand new to a hundred hours or so of use. just because it hasn't been identified ina lab doesn't mean it isn't happening.

well it's 15 feet Do you think long speaker cable lenghts really suck out the low freq's?
My option is to build a small amp-stand, shortne the speaker cables, and use a slightly longer 2 meter IC. Do you think this is worth doing?
not sure what you mean by X-over? I have the speakers bi-wired and using the speakers interal x-over.

Drag .... I didn't mean to seem as if I were running down anything that you were saying. I was in sort of a rant mode after reading the review from the link that was posted earlier.
What are the cones made of on those speakers? It's an electromechanical device, so moving them in/out a bizillion times could cause a change.

Oh, no no no... The pics that Curt was posting and those mod threads of the murdered equipment... Those were all about the Valhalla guy on AVS... He's overseas somewhere.
I have no idea what Gary looks like. Has anybody ever met him? The only two visuals I have when I think of him is the Ted Bundy avatar, or the Obama butt plug avatar.

I always wondered if that was really him, though.
This is from Gary's MySpace page:
OK, so that's Ted Bundy on the left... Is that Gary imitating Ted Bundy? If nothing else, it's an interesting choice of parody.

I always thought that was Gary. He comes across as a redneck skinhead type of guy a la his avatar. Looks a bit like Henry Rollins as well...

They have moving parts though.

true, the Kevlar drivers can be kinda stiff right out of the box. still, the differences were so big and varied throughout the frequency range it seems unlikely it was 100% material conditioning of the cones?
I think audio vacuum tubes also tend to change their sound after a run-in, not really any moving parts there unless you account for the electrons buzzing around. True also for CRT, you have to come back after 100 hours and completely re-do the stig and flare so something is happening in there.
This subject seems to come up so often I bet there's a scientific research paper in there somwhere.

That's Gary ... He used to have other avatars with real pictures of him and it looked the same.

I'd argue that your ears compensate the most.
Go listen either to a concert bootleg or AM radio for that matter. At turnon, your brain tells you that the recording or playback is sub quality, but listen to it for 1/2 hour, and unless you switch to a studio CD, it starts to sound pretty good all by itself. I record a lot of bootlegs, and find that every time I listen to one.

Peri, You run a legitimate business because you don't want to field questions from people like Gary.
Plus we would loose total respect for you if you were one of those buy my "magic cables" guy!!!!

HERE HE IS AGAIN!!!!
************************************** SCAM ALERT **************************
This is the same guy that sold me the $1,000.00 and $1,500.00 speaker cables claiming they were just as good as coat hangers, or maybe even better!!!!!!!!!!! Don't beleive a word he says!!!!
I am still without sound and a BOAT load of money. ( I bought cables for a 7.1 surround system )
Now, he is selling speaker cable "supports"? RIGHT!!!!!!!!! I ordered some, and I thought the box was rather small when it ariived.
What a rip off!!!!
BUYER BEWARE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

lexx21,
Welcome to the on going debate. RF transmission, very interesting stuff and no doubt the most finickie in the field of electronics design.
drag,
The longer the speaker cable the worse the damping factor looks (to the speaker) provided by the amp, add to that a crossover comprised of typically a cap and a inductor and now your damping factor might as well be zip.
Go to at least bi-amping and drive your bass driver directly from your amp with a couple feet of cable. Of course having an amp with a high damping factor will help tighten up the bottom end too. And of course that brings up the bass driver and its enclosure too. All these contribute to just how tight of bass you'll get. I 've heard a lot of very expensive audiophile systems (100K+) over the years at the local highend stores and I still haven't heard one with as tight a bass as I have on my system.
To start with I use a pair of 12" Dynaudios best bass drivers in a specially loaded enclosure which also includes a speaker mounting front plate which is 1.5" thick and made of solid lead ( yeah each speaker cabinet weighs about 250lbs). Mounting your drivers on a plate like that sure helps.
Actually I just about forgot about another very important factor in getting tight bass - GET RID OF THE HUGE EL CAPS IN THE POWER AMPS! THose things are just bad news when it comes to good sound.
If you want some good amps try to find some old Hafler DH220 or DH500 amps. In their stock form they're okay but can be modded into very good sounding amps.

You are bad. 
I should tell my story with Gary. I think the only people I have told are Bruce and Mark. I believe I told tse and Darin over lunch, but I can't remember. First, I must confess that I never particularly cared for Gary, but I softened my stance until I was pretty neutral about him.
Anyway, I had an XG that had black tubes and didn't want to spring for new tubes. So, I decided to part it out. Gary had purchased an XG and was having difficulty with it. I sent him a PM stating that I had some parts that I could sell him. He was interested and we agreed on a price of $300 for all of the boards from an XG LC. I boxed up the boards in bubble wrap and shredded newspaper. I used newspaper, because one of my suppliers found that his claims went to zero after using shredded newspaper. If you have ever received anything from my supplier, then you could see why.
I sent the box to Gary through USPS. When he received it, he emailed me saying that the boards where extensively damaged and that my packing wasn't that great. It is probably fair to criticize my packing as I am not a professional shipper. He decided that he wanted to send them back. This is where it gets interesting. His idea was to send them back and when I received them make a claim with USPS. In this manner, I could get some money for the damaged goods. I felt a little uneasy about this, but agreed. When I got them back, his packing was worse. I guess he was doing this so the parts could break easier. Upon inspection, I think two boards were damaged. One had some caps that were knocked off. The other I can't remember, but I think it wasn't to bad. I sent pics to Mark and I remember him saying something like "I thought Gary was a pro solder and electronics expert. He should have been able to put the caps back on in a couple of minutes.". I pretty much thought the same thing (Mark, if you don't want me using your name then I will remove the comment).
I ended up not making a claim with USPS, as I didn't think it was right to penalize the USPS. To this day, I still think either Gary tried the boards and didn't like them or more likely had something else lined up. |
More likely he swapped your good boards for his bad boards and made up that story so he didn't have to pay you.
Is there any way to know if it was your boards he shipped back?
