HE-500, LCD2, D5000, DT770, SR80, on a speaker amp (Emotiva mini-X A-100) Project - Page 73

post #1081 of 3639

Gotcha.

 

I only had the Magni.  I thought they were stand ins for one another.  I guess I still need to get a hold of an O2. 

 

But naw - my amps now are much better than the Emo.  I did enjoy it very much when I owned it thou.

You can use the m903 as a dedicated DAC to the a-100 mini.  The mini already has a volume control -

so i recommend using the volume control on the Emo.

 

 

 

Appreciate your response. Very helpful.

 

 

 

Is it necessary to use a separate DAC (like the m903) or can I just use the a-100 mini by itself with the headphone.

Thanks.

They pretty much are. The handful of in depth reviews peg them as very similar in sound and in SQ.

You should use the fixed lineout with the Emotiva, not the preamp/variable lineout.

the Emo does not have a DAC included.  So yes you would still need a DAC.

 

The a-100 / m903 should be a good combo.

Preproman/Khaine 1711* appreciate the advice. Another piece of advice needed. I am not sure whether to use my m903 with the Musical Fidelity (see below) or with the Emotiva. The MF is obviously more expensive being a well-known brand. Preproman,* you know the Emotiva pretty well though you may not have used the MF before. But based on your experience with hi-fi in general what would be your hunch as regards pairing the Grace Design with the MF. If you are willing to give your opinion it would be much appreciated. Thanks.

Low end MF stuff actually sounds kinda dry/bright. Don't get me wrong, I liked their Tri-vista amplifier, but the M1Dac and M1HPA were pretty bad.

 

If you got one in your house, no reason not to try it tongue_smile.gif. Use your Dac as lineout feeding the preamp driving the power amp, and post result here =p

If you got it,  might as well give it a try.  then you can be the judge on which one you like best.

post #1089 of 3639

I don't have the unit. Just one of the options being contemplated. Interesting to note the opinion of the Musical Fidelity DAC and Amp. Was on my sight too for a separate set-up. I usually like MF but maybe you are right the lower end stuff may not be as good.

Is anyone that is handy able to make a little box like this for me? It doesn't seem that complicated but i know pretty much nothing about electronics.... something I will want to learn in the next couple years....

Enjoy!

I actually just ordered a bunch of parts for various projects, including those needed for this setup.  I can assemble it and test it on my Mini-X this weekend then post my results, but I would be willing to help cool.gif

I did not have the skills myself and got the adapter built by a DIYer here in Spain. I will share my experience after I get the HE-6s smily_headphones1.gif

You can do it the peasant way (my way). The one with 3 ohm resistor in series circuit is 8.4 ohm. If you tie a 10 ohm resistor to the 8 ohm binding post without a resistor in series, it's actually ~8.3333 ohm, not much different.

 

 

 

+

 

 

 

The cable is aftermarket, but you can do the same to the stock cable.

 

This is for transformer coupled tube amp though. I feel that there's no need to use resistor on SS amps, if the gain is too high you can try line attenuator.

Wouldn't adding the resistors to the +/- binding posts essentially act the same/similar as an attenuator? What would be your recommendation to counter gain to reduce noise floor/low hum? Time for me to do some more research =)

khaine1711, I actually just saw your response in this thread which is what I suspected: http://www.head-fi.org/t/649107/speaker-amps-for-headphones/150#post_9402576  Catching up on the past 2 weeks here.
