My Geshelli labs J3 pro arrived today..it has the Sparkos 2590. I upgraded from Schmitt Modi3. I'm still picking my jaw up off the floor. It's like rediscovering the beauty of my collection all over again. Goosebumps. Did not expect this.
I have a J2S AKM 4493. I have tried the Sparkos ss3602 and ss2590 in the RCA stage. I find the ss2590 to be much more dyamic with a more emersive sounstage than the ss3602. Both are far better than the stock op amp IMO. Also both benefit from using a linear power suuply as does my streamer (a Wiim Pro). Thanks for introducing Burson. That op amp is probably the next one on my journey
I have a similar setup, but with the J2S 4499ex chip set. Agree with your observations re the 2590 Pros with the LPS. I view the 2590 Pros as providing the same magnitude of improvement relative to the 3602s as one would get going from the standard op-amps to the 3602s. It's quite amazing actually, and as you noted, the LPS enhances everything quite a bit further.
I have a Geshelli J2S with the huge Sparkos SS2590s in all three positions. Recently I was able to make a comparison between those and the Burson V7 Vivid. The Sparkos SS2590 is much the same character as the SS3602 except a little more expansive and textured. Your review very much agrees with my observations, whereby the Sparkos has slightly more relaxed and warmer presentation with layering focused along the edges of the soundstage with the Burson being a bit more lively with slightly more front-focused layering. Both are top-tier op amps. At present, I have the Burson V7 Vivid in the balanced XLR positions and the SS2590s in the single ended RCA, allowing me to instantly switch between the two, and I agree that each seems perhaps just slightly better suited for different types of music.
Thanks for sharing. Was there much difference between the sparkos SS2590 single ended and balanced ? You didn't mention if you have the AK4499 and which amp your using. Thanks
@@deadline7610 I upgraded from J2 AKM 4493 to J2S AKM 4499EX last year. I have two different headphone amps (Rupert Neve RNHP and xDuoo TA-26) and a Crown XLS-2502 for the speaker system (with meticulous placement and REW calibration). The differences between op amps is clearly audible with all gear. The SS2590 is excellent on all J2S outputs, and if there is any performance difference between the SE and XLR outputs, it is so slight that it is negligible. One advantage the V7 has is size. It can be easily fitted to all outputs, whereas the huge SS2590 can usually be fitted to the SE output without contact issues, although fitting them to the XLR requires an adapter to increase the height on one socket and an extender for the other. I detailed this exercise in the Head-Fi org forums.

Great stuff! I would like to try the Burson V7 Vivid at some point. I have tried the Sparkos SS3602 - and the big Sparkos SS2590 (two of them in a DIP8 adapter) in the RCA/single ended socket on my J2S AKM 4499 - and the big Sparkos is essentially more/better of the same qualities of the smaller Sparkos. The big Sparkos costs $126 MSRP but you can get 15% off by signing up for their very infrequent emails - so about $107; or $27 more than the SS3602. I hope you can review the SS2590 dual mono unit!
I compared Burson v7 Vivid to OPA828 - and it can't hold a candle to the OPA 828 for the high end that's above 450Hz. The speed and pin sharp detail and clarity of the 828 is on a completely different level because of its ultra-fast slew rate of 150v/uS. But that's playing fast, complex, recent and well recorded 24/192 EDM music/ vocals. If you were playing something slow and older the warmth and spatial nature of the Burson V7 might suit you better. For me, I ended up using the V7 in an active cross-over to drive the sub-base below 70Hz and they do a mighty fine job of that.
I have a J2S with SS3602's in all slots and Archel3 Pro with SS2590 pro from Geshelli. I don't consider myself an expert on audio but I can tell the Geshelli equipment is a decent step up from my ifi signature amp. You've done a very good job with this review and it answered my question about whether or not to upgrade to the Burson V7 Vivid. I think for the time being I will stick with the Sparkos SS3602's as they are an immersive experience for me. The archel's tone controls also help to sort of EQ the sound a bit and that's more important to me than swapping out the the opamps. Thanks again for a great review.
I approve of using these op-amps...I have them in two portable amps right now and they are game changing and excellent at what they do. Five steps above the OG Burson v5i. The clarity, separation and thump these have are NO JOKE. To fit them in the case for the amps I had, I got a dip-4 slot extender that turns the op-amp to the side (as opposed to the its normal straight up orientation).
Great comparison. Looks like Burson with V7s did lot of improvement over V6. Would you consider to bring Staccatto opamp from Poland (not far from you) it is also discrette circuit, which for many reviewers sound better than Sparkos. This would be excellent opamp battle! My Best!
Thank you so much for this very in-depth and relevant review of opamps. Helps to pull everything together and makes choosing a little easier. Would it be more beneficial to change the opamps in an amplifier instead of the DAC? Thank you again for your time efforts and for sharing your perspectives with us all.
Thank you for the review, Srboljub! I have been eyeing various Burson op amps for my garden stereo and this review gave me more meat on the grill, so to speak. I am currently running dual MUSES01 and while I find that the instrument separation is surprisingly good, I do lack a bit of punch and liveliness in the music. The Burson's a bit pricey though.
When I use the Sparkos 2590 in my mods (which is , so far, my favorite op amp....have not heard the V7 or Staccato) I modify them by removing the input protection diodes, damping them with small contrained layer material underneath the board and shorten all the pins and change the two input pins and the output pin to pcocc neotech 18 guage wire. Results in a cleaner and clearer sound, faster and at the same time less veiled and is more transparent and real sounding. Andrew Sparks knows that I mod them.....he actually told me where the diodes where on the board. I would try some small pieces of the EAR SD40AL damping material on the heatsinks of the V7....probably make it more musical or even more detailed....or both....but too much damping and it might make it slow sounding......damping is an art.
🤯 I thought I was one of the few that solders out the cheap IC opamps, puts in a socketed DIP8 adapter to enjoy my discrete PRO Sparkos opamps. Turns out there’s a level above me ... 😅👍👍
I have a Geshelli J2S 4499 DAC. I put two muses02 opamps in the two xlr slots. I like the sound of them, I'm no audiophile. I plan on putting some muses02's in my Fosi ZA3 at some point in the future.
Thanks for that perspective, and your analogy of the thre fat men is excellent: it really is a strong image and I understand much more than I did fifteen minutes ago. Good work, thank you very much.
I hope one day you will have a chance to assemble and review the IanCanada’s flagship Full function SYNC Clock mode DAC KITs. This design uses amazing quality parts and very intelligent design choses
You want more bass, just boost the low end on the EQ. Everyone is using DSP, that can change the sound much faster than having to disassemble your DAC and swapping out op amp chips.
Great explanation, I have a Hegel H190 and considering adding this DAC to replace the Hegel built in DAC, do you think this Geshilli beats the built in DAC in Hegel H190?
Everyone’s ears are different as to the speakers and audio amps used. I also watch several TH-cam reviewers and that’s where they are best in the web ether.
I have the J2s AKAM 4499 with sparkos 2590s and I’m wondering how this set up compares to the internal dac on a McIntosh C53 with the DA2 dac. Haven’t taken delivery of the Macintosh yet so I’m just curious if anybody has any opinions on the DA2 that McIntosh uses. Thx!
For my type of music (deathmetal) I think the default Texas Instruments sound better than Sparkos in my Geshelli dac. The sparkos seemed brighter and more forward. Maybe the sparkos will sound better in my Fosi ZA3.
I have about 300 hours on the Vivid V7 Pros in my J2S using a high quality very hefty 12v LPS and clearly prefer the V7 to the Sparkos. How would you compare this combination of V7/J2S+LPS to the SMSL SU10 and the Gustard A26 in terms of overall sound quality since you have studied all 3 quite extensively? Thank you!
