I recently sold my DAC-AH to a fellow HC'er. It arrived in good shape, but he had the following issues with it: I received it back today, again in good shape. I briefly powered it up without making any audio connections and there was no tingling or any other feeling of electricity. I touched the case in multiple places, including the RCA sockets. When I was using the DAC, I never had any electrical problems. One difference is in how we used it. The buyer used an optical connection between his source and the DAC whereas I always used a COAX connection. I'd like to debug this without electrocuting myself. I have only very basic electric circuit knowledge and definitely need some help. Could anybody suggest what is happening here? Why did the buy have problems, even after changing power cord, electrical socket and RCA interconnects? Thanks in advance for your help.

I see. Well it's nice that Ken offers a "bargain" version.

It's only $195 on the ALO website! Why that's darn right reasonable.

That's why you are getting shocked. It's God punishing you for watching trashy network TV!

Gene Kelly is dead! Definitely be the mouse!

Me too! To the OP, you can also look at www.headamp.com for more information.

Another fifth of Rebel Yell. I was out and am making "Bourbon Wieners" for a for a pot luck tomorrow.

Remember that the fellow is the mirror is very untrustworthy when it comes to these kinds of things. Keep smoking cigarettes and you'll be 50 soon enough too.

Vicki shares better than you guys do!

Vicki, please bring it to MOA. I'd like to compare its amplifier section with my AE-2.

I do one or the other. I either fill out and mail in the absentee ballot or I take it into the polling place. So I doubt that I'm invalidating my vote. They all scare me. I'd love to see a viable third party. One that's fiscally conservative and socially progressive. You know, kind of the opposite of the current administration. It probably won't happen in my life time.

What?

A bit? A bit?

At the moment, I'm a K340, Singlepower, eXemplar and APL fan. Of course, I can't (or won't) afford the latter. For speakers, I'm a Joseph Audio fan. These all could change at any time. I'm pretty much permanently a tube fan.

Nope. I do absentee voting, so it's only a matter of a little time with a pencil and a stamp. I don't do it for every choice on the ballot, only when all the choices for one office are bozos.

Because of the choices, I often write in "Jerry Garcia". He'd still do a better job than most of the jokers running for office.

Technically, Jack Daniels is Tennessee Whiskey. Edit: Jacob beat me to it.

That's right. Steve, how long does it take for the magic solder to burn in??? P.S. I have one of your Hammond cased Pimeta portables. It's a nice little amp. I just used in on the train rides from SB to San Diego and back.

Oh come on. Everybody knows that commercial manufacturers have magic solder that makes their equipment sound much better. Of course, only after it has been burned-in!

We can do that after everybody leaves. Wait a minute, nobody is leaving. Uh oh!

Maybe Todd would give you a loaner to take to MOA? If it's a good deal, he would be smart to do so.

Hi Aaron. I'm not going to jump down your throat. I'm sure that all those components sounded better to you after they matured. I'm sure that a lot of burn in occurred. Let's look closer in the case of a new amplifier. On one hand, you have a pretty simple electrical device that will change slightly over time. There just isn't much there that can change. On the other hand, you have the brain, which is processing the signal from the amplifier via some wire and a transducer. The brain is an extremely complex biochemical device. It is very flexible and adaptable. It shows almost constant change in how it works. So over time, I'm willing to bet that the vast majority of burn in is occuring in the brain and only a minute amount occurs in the equipment. Notice that this doesn't invalidate your belief that the equipment sounded better over time. It's just that your brain was doing most of the changing. My favorite case of brain burn in is the experiment where a person was given given glasses that inverted all images. The subject had to wear the glasses during all waking hours. After several days, suddenly the images that the subject saw were right side up again. The brain had burned in a bit, eh? Then the glasses were taken away. Again images were inverted to the subject. Again after several days, the brain righted the images. I have to believe that similar experiments would show the brain doing interesting processing on aural input. -ken Life was unlistenable out of the box!

Hey JP, I sure hope that this wasn't a freudian slip!

Mike, if I drive I'll bring both my eXemplar Denon 2900 and a SACDMods Eastsound E5. If I fly, people will have to be happy with my iPod and AE-2. Of course, it's no longer a $1400 eXemplar. I had John Tucker put in the latest mods and now it's an $1850 eXemplar.

You mean ask Ray?
