But how would you know?
If you have to run something through something, ie can't be run alone... You can make inferences and assumptions based on lots of stuff but you'll never know.
 

I believe every headphone/earphones have their own sound signature, no matter what you run it from.
Signature will always be there, but perhaps the level of distortion differ from amp to amp.
But who am I to judge this? I've got no amp, little inventory of headphones and most importantly, a noob
 
 

Yes, shatterer of dreams, destroyer of hope, eater of pasta... wait.

   Well, at least I got chicken (If you know what I'm saying )

The 8610 and 4627 sound extremely similar to my ears. I'm not positive I could tell them apart in a blind test. Of course YMMV.

 
Has anyone else been able to directly compare these 2 op-amps? I'm really interested in pulling the trigger on this amp but want to know what the perceived difference is, no matter how subtle, between the 8610 and 4627 specifically.
 
I'd be using this primarily with the SRH1540 and HD600 if that matters. Maybe the safest bet is to just go with the default 8610 if it provides the best "balance".

If it helps, I much preferred the ADA4627 over the OPA209 with my UERMs and HD600s. Haven't done much testing at all with my hd800s though.

I'd go with the default op amp. Then, if you want, buy more and experiment later.

Yes I directly compared these at length and was unable to come to any real conclusions about sound differences. They sound so close to each other that I can't be sure that there's any real difference at all. I would likely fail a blind test between the two. So I sold the 4627 and just kept the default 8610. 

 

[Kendoji]

As Nick says, when in doubt get the default opamp.

 

[thegrobe]

After screwing around swapping several opamps in the mk2, I always came back to the 8610. The default that was in it from the beginning!

I'm glad to see the 8610 spec'd in the new 760.

 

[rpaul]

Thanks, the default 8610 it shall be.

How does the UHA-6 MKii (with optical) compared to Modi/Magni?

I actually prefer the Leckerton plus Modi. Over the Modi + Magni.

I actually compared these two setups too. I like the Leckerton + Modi combo with my CIEM over the Modi + Magni. 

 

[robm321]

Yeah, while people complain about the USB DAC limitations (rightfully so to some degree), via optical, the DAC is very very good. Not the best out there, but getting a top rate amp, and, by the way, a very good DAC for under $300 - a steal. 

 

[Bazirker]

Why is the DAC different if the digital signal comes in via optical rather than USB? Would optical and SPDIF have identical performance?

 

[robm321]

The SPDIF inputs are functional up to 24-bit/96kHz while USB tops out at 16-bit/48kHz.

Picked up a 760 and put my 6S up for sale if anyone's interested. Really liking the 760 so far. The digital volume is great, and three gain levels gives some more usable volume for really sensitive iems.

Have you noticed any sound difference between the two (say with the crossfeed turned off on 760 and both at lowest gain)?
