HE-500, LCD2, D5000, DT770, SR80, on a speaker amp (Emotiva mini-X A-100) Project - Page 245

post #3661 of 3673

Hello, so I'm planning on upgrading to this amp setup that you guys have for my Alpha Dogs and my HE-400i that I will upgrade to an HE-560 in the future. I would like to ask about other possible costs that I may have to purchase if I go this route. Along with an amp, I need an XLR to speaker taps adapter or the adapter Ca5bah has mentioned using TRS cables along with a DAC correct? 

 

I was wondering if I just purchase this amp and connect the cables as is? I would love to remove the channel imbalance that was mentioned at low levels, and have the front panel installed but I have zero soldering skills so that might be an issue. It can be an excuse for me to learn how to solder and whatnot though... Or I wouldn't mind paying someone to do it for me + payment for the parts. Agh I don't know, I was initially looking at the 10.33 and getting balanced XLR cables but the emotiva route seems to be more power for cheaper for orthos.
 

Lastly, are there any potential issues or dangers with this setup?

 

*Edit: was also wondering if it's safer to go XLR to speaker taps than TRS to speaker wires?

They might, why dont you just call them? I had mine anodized black for the Gen 1. You can see my build in the link I posted in the post above.

I think I might just give them a call. I basically was trying to get the look you have without buying a whole Gen2 unit or having to go through anodizing. Looks like they didn't really change much in the realm of SQ for Gen2.

Hey,

 

I use speaker amps and a Lyr 2 with my 560's, you just need to take care with the volume nob, way down when initiating. If you use a tube amp, a resistor box, like the one Hifiman sells is recommended to provide a steady, resistant load for the amp.

 

I don't know why you couldn't go from speaker taps to TRS, mine is balanced, and the other's I have experienced are balanced as well, check with someone like Trevor at Norne for that answer.

With TRS the amp needs to have common ground (L- and R- shorted). It's okay with the Emotiva mini-X, but if you want to try other amps, you have to make sure they have common ground.
XLR is generally a safer approach when switching between amps, because L-, R-, L+, R+ are kept separate.

Hi team!

 

Quick question, if anyone has any thoughts of experiences it would be much, much appreciated.

 

I've got a Peachtree DAC >>> Emotiva a100 >>> LCD-2F

 

However, I can't turn the blasted volume knob on the mini-x more than 1cm, seriously, past say 7-8 o'clock before it gets waaaaaay too loud and painful. It's a pain especially as there is a slight channel imbalance at 7 o'clock too. If I turn it a bit louder to fix the imbalance, again, it's way too loud.

 

 

Kind of in a pickle at the moment because I love how the damn thing sounds :)

 

 

I was wondering, If I hook up something like the Schiit SYS in between the DAC and the Emotiva, would that allow me to lower the volume of the DAC's line out? Essentially allowing me to raise the volume on the Emotiva and enjoy comfortably?

 

 

Much thanks guys/gals!

 


Cheeeeersss

I've kinda got the same problem, solved it with a 12 dB attenuator box on the output. Even then the damn thing got way too much gain on HE-500 but it's usable. The schiit sys approach will work too but will not cut down noise and that sort of stuff.
post #3668 of 3673

Ahhh no worries, thank you!

 

 

Not really bothered by the noise as it starts from about 12 to 1 o' clock onwards :)

 

There's a very slight hiss that's always present but I've gotten used to that!

 

 

Plus, I've got very slight tinnitus and with my flawed logic, they cancel each other out hahaha

 

 

Thanks Davidsh!!!

post #3669 of 3673
Ur welcome. I experience a slight hiss too, but I find that bothersome at times
post #3670 of 3673

The hiss is exactly why I installed the inline attenuation (with resistors) in mine to lower the gain and also provide more play in the volume knob for headphone listening.

post #3671 of 3673

Thanks for all your help guys :)

 

The inline attenuation and/or box looked too complex for me so I ended up with a Schiit SYS, works pretty good.

 

To confirm, it's not a bad thing to lower source volume right? (I read in some long forgotten thread, it could cause clipping? No idea why)

 

(e.g. I have the Peachtree itx >> SYS (30% volume) >>> Emotiva @ ~50% volume (rather than the usual 10-15% volume setting))

 

 

Thank you all again 

post #3672 of 3673

In general, the topology of most "normal" amplifiers, including the Mini-X, has the volume control as a potentiometer/attenuator on the input, with a fixed-gain amplifier block after it.

 

This means that the output will always have some minimum noise on it that won't change much no matter where the volume is set (this is the noise floor of the amp); in addition, of course the amp will amplify any noise coming from the source (and many sources similarly have a minimum noise floor on their output). Optimally, you want the output of the amp connected directly to the headphones, so you get the best possible damping factor, so you're stuck with the noise floor of the amp itself. To find out how much noise that is, just run the amp with the input shorted (or, on most amps, it will be pretty much the same with no input connected).

 

However, if there's noise coming from the source, putting an attenuator between the source and the amplifier will help reduce that (although the volume control on the amp is already basically just an attenuator on the input anyway). However, adding an attenuator before the volume control will allow you to run the volume control at a higher setting, and shouldn't otherwise affect anything. (It's not going to cause clipping unless you attenuate the signal so much that your source can't provide enough signal voltage.... at which point it's really the source clipping.)

Hiya team!

 

Does anyone have any recommendation for an upgrade for the Emotiva mini-x a100?

 

Have the LCD2 Fazors and wanted an amp that might have more oomph on the low end, sub-bass wise! :)

 

For example, has anyone A&B'd the Violectric HPA 181 against the Emotiva?

 

Or any recommendations?

 

 

Thank you! :)
