I have the T1, and it does power the HE-500 pretty well. It very easily satisfies me when I don't feel like hooking up a speaker amp.

 

If you want warmth and bass though, you want something with tone control or bass boost. The Lepai works well here for fun, and is cheap.

The amplifier's output audio signal is an AC wave.  Like I said, when two positive voltage waves or two negative voltage waves combine their voltage amplitudes are added together (summed) and that double voltage spike could generate enough heat in the headphone drivers to melt something and "blow the drivers." Nothing I originally said is wrong, and yet I get a freakin' "Argh." Argh.

 

No, not quite, and I made other points that you seem to have glossed over. Perhaps your particular wording is just not jiving with me, and I think we may have been referring to different pictures anyways. Whatever. It's not worth arguing over high school physics and L-pads circuits that have been around for decades. A lot of those L-pad calculators can be found online too.

 

Kids, don't touch your +'s together. Most of the time you shouldn't touch the -'s together either. If you're not sure, then don't. For the rest of it... ah forget it no one listens anyways.

 

I think I'm going to clock out of this thread for a while.

Stop recommending the Lepai. No one wants it. I will never buy it. Stop. Please. Stop. Stop. Stop.

 

OK now that I finished that, I don't want to power the HE-500 directly from the T1 rather than use it as a DAC for the Emotiva and HE500 setup that I currently am using.

It's always hard for me not to, but I've always tried to avoid it. The banana plugs conduct throughout the whole plug so it can be difficult to not touch them when moving them around :P

I have a Aune T1 but not an Emotiva but the T1 sounds freakin' great and I would think its tube DAC would pair nicely with the Mini-X.

I put some fat heat-shrink tube around the black banana jack bases to keep them from shorting each other.

Alright, I'm definitely leaning toward the Aune T1 now. Just gotta see how I like the Modi first. And yeah, that's a good idea. So, it's bad to touch any two plugs together? What's the most dangerous two to touch?

What? That shorting a battery can cause sparks and heat? I'm glad you straightened me out cause I had no idea.

 

My original description of the electron flow through the misconnected TRS adapter is spot on.

I like this robrob guy

That's some strong koolaid.

You won't see me posting in this thread for awhile either.

With a single-ended output amp you can obviously touch (short) black to black (- to -) with no problems because they are already common, but short the + to + or + to - could cause damage.

 

With a balanced output amp even shorting black to black can damage the amp.

Which would cause damage to the headphones?

Well it sounds like the amp has protection circuitry, so it would be  unlikely if it's implemented well.

I think any of them could cause headphone damage because shorting the speaker output terminals can cause the amplifier to do strange things when it's blowing up. Most modern solid state amplifiers have protection built in for speaker shorts.

And the upa2 has as well. Don't rely on the protection circuitry. Don't want to discuss this further it seems we are getting nowhere for some reason.

You'd be surprised, plugging it in and unplugging it when the amp is on doesn't make much noise at all (maybe a couple db above the noise floor). Turning the amp on with the headphones plugged in doesn't make much noise either, but turning it off makes two quiet pops. Neither way would be an issue or cause any damage as far as I am aware, but I don't want my headphones plugged in on the offchance someone is messing with my amp when I'm not there.
