Which DAC among Gustard X26 Pro/R26 pair better with this amp and Arya Stealth?

I would go for Gustard R26 and alternative opamps. The DAC is apparently much better than the X26 but with the R2R warm sound, if you get a transparent sound from the Burson 3X GT with alternative opamps you will have one of the better setups possible for your headphone of choice.

Alternate opamps means a mix of vivids and classics right?

Sparkos, SIL, Staccato etc.. see the previous posts in this thread

Okay, I've been playing mix-and-match all weekend between the following op amps:

- Stock red Burson
- JRC 5532D included in the amp box
- SIL 994
- Sparkos SS2590
- Burr Brown OPA2134PA

My absolute favorite combination is... stock red bursons on input and volume, and Sparkos SS2590 on voltage output

Funny how that works, I could have saved myself lots of money

Still interested in trying those Orange opamps though

Did a little more testing with my op-amp rolling issues and this is what I found:

1) Neither the 994s or 2590s in the volume control stage result in audio coming out of the amplifier.
2) Both the 994s and the 2590s output sound when in the input stage and vivids in the other 2 stages.

So now I don't believe either set of op-amps are the problem, but I don't understand why neither in the volume control stage will allow for audio out of the amplifier. The volume control stage works when I have vivids in them, but not when I have 3rd party op-amps in them. Very weird.

As for the sound with the 994s vs the 2590s in the input stage, I prefer the 2590s. 994s seem to darken the sound with bringing up the lower end and taming the mids. Not sure if I'm hearing much difference from 2590s to vivids, but I do enjoy the sound I'm hearing with them on the amp.

when you hear the Orange Op-amps, you will forget about the equipment and listen to music all day..

Are you saying all 6?

Also have you compared them to others?

yes.

for volume i use -130 db op-amps from alfa rppar . it's a company from Latvia. I accidentally found them via a russian youtuber!

the bursons smear details... in comparison

So are you suggesting orange or alfa rppar? And all 6 of each or a mix?

 

[sawindra]

I use alfa rppar as402 for volume buffer
Orange duals for voltage stage
input stage i switch between Sparkos Pro 2590, Muzg duals and Orange Duals


70% of the time the sparkos..i prefer

Final update on my op amp issues. Reached out to Burson audio support and they advised me to not use third party op amps as customers have reported back with burnt headphones or fried units. They don’t cover them through warranty and so only recommend I use their op amps in my unit. Unfortunate as heck, but I suppose I’m just unlucky that my volume stage won’t accept third party op amps. I’ll likely sell my 994s and stick with my 2590s as I prefer the sound with them in the input buffer stage. Might try out the v6 casuals since they should work in the volume stage.

I am trialing this config. So far outstanding and the most “tube-like” of anything I have tried. Need more time evaluating, but I really like what V6 Classics bring to the table. It’s the first config where I stop thinking…and just get lost in the music. I can also now explore more of the high gain setting now on the GT without it feeling like overkill. Man, this thing is fun to own.

Im surprised they would say something like that, unless my memory is wrong Im sure they used op amp swapping as a selling point. If that is the case, they need to offer more than 2 options of op amps considering people have seen pretty sizeable improvements swapping out the v6

Attaching my correspondence with Burson audio. Apparently others have complained about the Sparkos.
