Just too loud or too much power? I guess that goes hand in hand. How much wattage was your amp?

Too loud put too much power on them at once. The amps are 125w. The drivers will only take what they need based on what you want for db.. In my case, I had bought a new DAC and didn't take the time to know how to set it up first. The input was boosted 24 db + the output was boosted 24 db for a combined +48 db into the amp. Not good. I now use the same DAC with a setting of 0db boost on both and drop the volume by about 10 db for perfect operation. This is a pro audio AD/DA converter so it has too many options for the hobbyist.

I've ran the same headphones on 450w amps with no problem.

The shiny part has always been there, it's part of the driver design.

And I have a myriad of floating questions like: Would I be able to use banana terminated plugs on an external resistor? How would I check the values from an external resistor? Etc.

 

Would be great if there was a guide to all this, but it looks like it's just dispersed throughout several threads on this forum.

 

We're always seeking volunteers to work on a FAQ and keep it updated.  ;)

I have my banana plugs well labelled on my HE-500. Have had them hooked up to a 150W amplifier with no problems. Just make sure you have the volume set to its lowest and switch your equipment on in the correct order.

 

A couple of years ago a speaker wire came loose on my Rotel amplifier by accident and shorted to the next binding post. It wasn't pretty and basically the Rotel's guts had to be replaced at a cost exceeding the value of the amp. Fortunately it was still under warranty and the great folks at Rotel agreed to fix it!

I made a point to use one type of banana plug for positive, and another type of banana plug for negative. It's still a worry for me, though. I use the same amp for my speakers and for my headphones, so there is somewhat frequent unplugging and plugging. I'm going to grab another amp strictly for headphones as soon as I can (one with less power).

I use a headphone extension cable with banana plugs on one end. Therefor I can still have speakers connected by piggyback or use the speaker lugs to the amp post and then use the banana plugs with the headphone extension cable. Latter I may get a headphone box.

Would the mini-x be too powerful to drive the Mad Dogs reasonably?

It's not too bad. Not a lot of play with the volume. I enjoyed it but felt that it accentuated certain aspects of the MDs and brought out a little too much of a V-shaped signature.

Just my personal opinion and you may not have the same experience or even prefer it.

I love the Mini-x so much that I am going to run them Mono-block style.  :D

Hmm you should check my recent post on the XPA-1L in the other thread: http://www.head-fi.org/t/551345/hifiman-he-500-he-as-in-high-end-impressions-and-feedback/9750#post_10055168

Was it very hard to add in a plug in the front of the amp? I remember you (or someone else) posting a couple pictures of it a while back. Do you have any inside pics of the operation?

Here's a link to the post in this thread with a few more details, pictures, etc. on how the 1/4" jack was mounted into the front panel.  The work looks excellent!

Oh, with this amp on sale for $169 (again), I think it just proves that the few times each year Emotiva runs a sale, they are crazier than Schiit for what is offered.  :D

Sweet, thanks a lot. I guess I would just solder on the insides of the outputs? the hard part is the hole I guess.
