Mal has indicated that it's preferred it's not necessary for his HE-500, but other planars like the HE-400 and MadDogs benefited.  It is apparently beneficial for most some planars (to help reduce the noise floor) and to allow more sensitive dynamic headphones to be powered safely.  I can say it works well with my HE-400.

Where did you end up getting your resistor from?

This is the same one that Brian used according to Mal.  You just need one per positive connection.

Heya,

 

Yeap, it's not necessary though at all. It would be probably a good idea with an amp that was 80watts or more. But at 50 watts, the HE500 doesn't need a resistor adapter of this magnitude. I had this adapter made specifically for the very sensitive headphones to be paired with the emotiva (or any speaker amp for that matter) as well as with my OTL amp where it peaks output against higher impedance (load). The HE500 doesn't need this, it's not sensitive compared to something like the Denon.

 

Very best,

Question for Mal or anyone running this amp. Have you guys noticed the sound stage with this amp tends to follow a "3 blob" presentation like the Mjolnir has? By that I mean sound comes from directly left, directly right, or directly center? Did this change at all with resistors?

Heya,

 

I haven't really noticed it being distinctly left/right/center for me, with or without a resistor adapter. I found it to be headphone depending in that sense. For me, the LCD2 sounded a lot more left/right/center. The HE500 however to me sounds like a cloud blended across the horizon. For me for example sometimes a vocal in some of the Swing I listen to seem to be off in the corner, not completely to the right, but not centered. I have a lot of vocal arrangements and everything is pretty laid out in a crescent, nothing is ever "just" left/right/center for me unless it's recording specific. I also test this with my speaker setup for comparison on the same tracks to identify sound stage differences in a track. But that's just my experience so far.

 

Very best,

Yea I somewhat agree with Mal. It depends on the phone. I've found the Emotiva to work best with speakers though in terms of proper soundstage though.

Thanks for the comments. Maybe I just need to sink into the music and stop picking on details. Happy listening to all!

No, no. Your comments were definitely justified as I recently was feeling the same thing with HE-500 for the past 2-3 weeks. Early February, I was absolutely loving the HE-500 with Emotiva. Although after listening to the LCD-2 for a couple of weeks, the HE-500 sounded off - specifically lacking in the centerstage. I think I'll probably try to get some more music and/or take a break from headphones for a while. Who knows, maybe a good break will get my love for them back again.

wouldnt the source or headphone have more effect on hearing that though ?

 

can you give me some recommendation on songs or specific tracks that I can listen to to try to notice this?

I think this may in fact be a result of the tracks I was listening to. It was a live recording and must have been placed on stage in front of the musician with the crowd left and right :/   Haven't had too much of a chance to sit down and listen. 

 

 

 

Quick question for all of you on the resistors (since I am not electronically inclined): Instead of having an adapter like Mal's, could I just use a resistor in line, like this?

this might be a really dumb question

 

if I have active speakers with RCA inputs on the back, I can just run the rca cables from the emotiva into the speakers and use the emotiva to control the speaker volume right ?

 

would the emotiva also still be able to power my headphones/passive speakers from the speaker outputs in the back or will the sound signal only come out one of them ?

 

 

 

 

side question:   say I am running laptop --> bifrost  --> active speakers

 

                        the bifrost DAC does not have volume control, so the only volume control would be on the laptop.  would this have adequate control over the speakers ?

Answering your 1st question:

 

 

Quoting Page 9 of the mini-x A-100 manual:
 
Connecting the analog (loop) Output of the Mini-X A-100 to another device
 
The Output of the A-100 provides another copy of the input signal for chaining to another device. The output signal is the same as the input, is buffered (so it won’t load down the input device), and is only present when the A-100 is On.

 

So, the volume control only affects the speaker terminals, not the RCA outputs.

 

Answering your 2nd question:

 

    Those RCA outputs can be used at the same time as the amplified (and volume-controlled) speaker terminals.

 

Answering your 3rd question:

 

    I would set it up like this:

 

    laptop > Schiit Bifrost > mini-x RCA Inputs >  mini-x  >  mini-x RCA outputs > active speakers

 

                                                                                                     >  mini-x speaker terminals > headphones or passive speakers

 

Leave the volume control on the laptop at maximum, so that you are not reducing the bit depth (dynamics) of the digital signal being sent to the DAC.

 

Use the volume control on the mini-x to control the volume of your headphones or passive speakers.

 

Use the volume control built-in to your active speakers to control their volume.

Regarding those resistors and their application, I'm not sure of the benefits entirely in comparison, or if they would be beneficial to add...it does look similar to HiFiMan's own adapter posted by wuwhere earlier in this thread:

If I'm reading this right, it seems as though they used 10ohm resistors to 'absorb' some of the current?
