Asus Essence One Headphone Amp/DAC (CeBIT 2011) - Page 228

post #3406 of 3417

@raoultrifan - sorry man, haven't had time to do an A/B comparison of the Essence with the Burson's. I'll try get to that and report.

I finally received my 7812/7912/7805 from the US, so I'll be looking at replacing stock at some point.

 

I have received my HD800's (after some stupid import issues). Noticeably better than the HD650's I was using prior. Very impressed.

I actually have a balanced cable that came with it but am currently using it with the normal front 1/4in jack

 

This brings me to the question: has anyone driven balanced headphones direct, with the balanced outputs on the rear of the unit? Is it doable?

You should not directly connect balanced headphones to rear XLR plugs; they are intended to connect to a power or headphones amplifier only. Besides, on XLR outputs you don't have enough current to decently drive headphones and there might be an impedance issue as well. Also, output buffers might break, depending on the headphones used.

 

I DIY a XLR>6.3mmJack adapter to connect balanced headphones to my Essence One output jack. All you need is a 6.3mm jack and a 4-pin XLR one, of course a decent cable between the 2 connectors.

Ah yup, thanks for the heads-up. Figured that was the case (which is why I haven't done it already).

 

My current setup is using a balanced cable that terminates to an XLR-to-6.3mm cable - if that is what you mean.

 

Also, you mentioned the Jotunheim above... do you have experience with that piece of hardware? I think I'm almost ready to migrate from the Essence One and move on to superior kit. Recommendations?

 

Sorry to barrel you with questions, raoul - but it's your fault for being a good source of information :P

Thank you damier for the kind words. :)

 

Don't have experience with Jotunheim and I'm not sure it can be considered as a real upgrade over the Essence One (especially if we're speaking of MUSES version), but I'm sure it worth a try. What I love to Schiit guys is that they're really engineers and they do know how to design a Hi-Fi piece of equipment (low noise internally power supply, great decoupling, minimise jitter or re-clocking etc.). Perhaps you could check out the Jotunheim forum here on Head-Fi and in case you'll buy it please update this page too for details and A/B compare (if possible).

 

Regards!

The new set up (827 in I/V) runs cooler than 49990. 

post #3411 of 3417

Has anyone tested OPA827 and Muses 8920 in I/V? If yes, kindly share your experience. 

post #3412 of 3417

I need your help:

 

I am getting a scratching noise only from the left speaker (audio out) when I turn up/down the volume knob on Asus Essence One. It goes away when I stop the movement of the volume knob. Also when I move the knob to lower volume, the output drops dis-proportionally on the left side as compared to the right channel. At full volume, left channel performs perfectly.

 

There is no such noise from the right spk when I move the volume knob either way.   

 

While there is no such noise coming from headphone output (left or right side).

 

I didn't notice this issue earlier so I am wondering whether this has to do with my changing op amps yesterday?

 

Kindly advice.

post #3413 of 3417

I changed the op amp in the audio out section and the noise went away.

 

i think the soldering of the 827 opamp was not done properly on the board.

I just bought two V5i's as I still have the V5's -- I was planning on keeping the V5's in LPF and replacing the V+Gain MUSES02 with the newer V5i's. That would be best, no?

 

Regarding how I made the V5's fit; Burson sell 3cm extenders. They can be found on their website: https://www.bursonaudio.com/products/supreme-sound-opamp-v5/ -- quite convenient


Hi,

 

I recommend 2xV5i duals for the LPF and for headphone gain stage either 2xV5i duals either 2xV5 duals with wire adapters or angled-DIP8 adapters. There will not be much difference between the MUSES02 and the V5i duals in LPF, but if you can A/B against another device it would be great. In this moment I have 4xV5i in my E1 DAC: 2 in LPF + 2 in headphone gain stage.

 

Cheers,

Raul.

Has anyone tried AD797? Which model (AD 797BRZ?) to be used one Essence One? 

post #3416 of 3417

You really need to dig into this forum a bit more: http://www.head-fi.org/t/542563/asus-essence-one-headphone-amp-dac-cebit-2011/810#post_8300531.

 

You will find a lot of posts regarding opamp changing in Essence One and most of the opamp rollers recommends to use opamps recommended by ASUS; otherwise, read carefully opamp specs and use a scope.

 

P.S.: If you don't want to spend money on expensive opamps, then you can use MUSES8920 in I/V and MUSES8820 in LPF, Headphone gain and Output buffers stages.
