The Best Tweak EVER In The Whole Audio Industry

[@Alamo-cz5xc]

I have the dual ss2590s in a Geshelli Labs J3 DAC and in my humble system it sounds fantastic. Doing business with Sparkos is a great experience. Andrew Sparks is a cool guy.

Aside from having the best op amps I've ever heard, Andrew Sparks (the Sparkos founder) is not only one of the friendliest, but also one of THE MOST hilarious guys I've ever met in the industry. Add in the fact that they're insanely reasonably priced, and you've got a win/win/win. His products have certainly been transformative in my gear.

[@onemic-theminimalist]

These Sparkos opamps have been known in the pro-audio world for years. I have them installed in several EQs, mic preamps, and amplifiers. The difference you are experiencing may vary depending on the quality of the rest of the circuit you apply them to. However, overall, they are really nice-sounding. WARNING: removing an opamp from a PC board takes skill and will void any warranty. Very few manufacturers use swappable chip sockets.

If the op amp is surface-mounted (soldered) on the PCB, there is an adapter that allows the installation of a DIP-8 socket. Of course, you need to have the skill to do it, but this kind of equipment upgrade also implies some DIY skills. I believe that everyone is fully aware that such and similar modifications lose or limit the warranty.

[@onemic-theminimalist]

The biggest issue is removing a PC board from the circuit to access the bottom of the chip's pins. This can be pretty difficult if it's a complex circuit like an EQ. You will rarely find the accessible swap-out socket you see in this video.

[@StephenMcGregor1986]

The best and most inexpensive tweak I’ve ever done to my hi-fi is ignore the advice of those who claim mains cables make no difference. They indisputably do.

I had the same experience with my system. Replaced the rca output amp on my D90 AKM and whole new world of soundstage and detail I have not heard before. Decided that it could get even better, as the rca output op amp is driven by the XLR op amps, so I replaced the XLR op amps and used the XLR outputs single ended. More goodness! All had to be adapted and soldered in as the LME49720 originally in those locations are soic. Several hours work well rewarded. Considering doing the 4 I/v converters next, but sounds sooo good now I am just listening. All other amplification is tubes into Aerial 10t speakers.

[@jakephilbrick7384]

Two commercial op amps I always recommend people try. Opa1612 and opa1656. I'm convinced you'd have to try real hard to get the 1656 to oscillate. The 1612 is a bit more picky, but if it integrates with the circuit well, is probably one of the clearest commercial op amps (for audio) that currently exists. If the circuit doesn't play nice though, it will ring. Also better to replace another smd part with these, as the parasitics from the dip8 adapter alone can cause issues with the 1612.

[@oddmagnusbjerkvik5119]

Yes, those are good.

[@Jeep_on_audio]

Just try these and you will be convinced. These Sparkos are really that much better. Unless you're in a tight space then try Burson V5

[@raymondc9896]

I also like the opa1642. In most cases it has produced a lower measured noise floor over the 1656 and 1612 with no raise in thd.

[@jakephilbrick7384]

@raymondc9896 I guess I'm going to read a data sheet. I find it hard to believe that it would have a lower noise floor than a 1612. Almost certainly the circuit coming into play. Especially considering Johnson noise is going to be the dominant noise, at least with the 1612 in a circuit designed around it.

[@jakephilbrick7384]

@raymondc9896 indeed, the 1612 itself has "much" lower noise. 5.1nv for the 1642 and 1.1nV for the 1612. So I'm guessing the noise you're getting on the 1612 is its interaction with the circuit as a whole.

Even if the company goes out of business their components will still be in existence ! Anything you speak on is disposable tech ! The proof is you will be getting something else quite soon that will be the greatest thing you have heard ? And this is very possible, but it does not instill buyer confidence or brand loyalty? Resale? Fogetaboutit ? Music has not changed the notes are still the same! Our perspective and resources has changed! The longest line to heaven is sinners trying to book a flight at the last minute... audio allows you to hear what's going on with the music you listen to from what ever time it was made in ? Led Zeppelin absolutely said it best on stairway to heaven... you can't buy your way out of this! A lot of these things are cute it's like the Dynaco days of building your own equipment on a budget, and you learn something! Which made places like Radio Shack possible !

[@anthonyjackson7097]

I must be honest. $79.00 for any op-amp is not cheap! What I have seen over the years is that monolithic op-amps out perform discrete in any and every measurable way. I think Nelson Pass demonstrated somewhere with a discrete line level circuit that he could mimic all the so-called warm 2nd order harmonics found in tube amps. Texas Instruments, etc. do not design added 2nd order harmonics to their op-amps. Sparkos, Burson, and others are suspected of spiking their designs this way with 2nd order harmonics. It can be measured and has been several times. If you like the sound, I am all for it. But, if you want honest reproduction of a signal, these discrete designs are going to be your worst choice. He'll, why not a discrete vacumm tube op-amp? Or better yet, a Model T Ford racing at the NHRA Winter Nationals. There is a reason why technology advances and surpasses previous technology. If discrete op-amps were better than modern monolithic designs, you would see them in computers, televisions, and everywhere else they are used. Tube amps are liked because they add artifacts that are pleasing to the ear. And yes, I own tube amps.

[@kineahora8736]

I’ve seen tracings of the frequency response from these discrete op amps and what I noticed was *Lack* of 2nd harmonic that was more prominent in the monolithic op amps-sorry but I don’t think you are correct at all. Now: if you are gonna argue that people cannot *really* hear the difference because they aren’t doing proper blind listening tests with gain-matched testing and proper A-B-A sampling where the listener needs to identify correctly which was the B and which were the two A… then I am listening🤣🤣

[@realhi-fihelplarry8047]

What is several steps beyond this, is the su-r1000, it is an amp/DAC without op amps in it, and that does NOT use a chip when using the USB signal. Meaning that you basically have the most optimal amp/DAC and bypass this op-amp negotiation of sound. Mcintosh type of brands use a gigantic amount of up-amps in their products, and it really kills the sound/steers it. And gives it and edge type of sound that is very flat. Yes I believe Danny in this specific case because of fitting the specific design. But ultimately you want op amps out of a system.

[@timmiee32]

Hope they start offering kits soon! 🤞🏼

[@pandstar]

Did I get banned? I posted earlier about other comparable discreet op amps, and they are not here, or on my history page. I'll try again. Sonic Imagery and Staccato make very well reviewed op amps, too.

[@dannyrichie9743]

You are not banned.

[@Pete.across.the.street]

Happened to me as well

[@MichelLinschoten]

Its always funny that audiophools super hearing powers diminish the second you spew these two words... Blind test ...

[@dannyrichie9743]

Not around here.

[@ThresholdZhor]

I'm gonna try it on my APT Holman preamp

[@markconner5569]

You Sir , go back aways.

[@CanberraProtest-dm6hu]

Ive never heard an op amp or chip power amp that I like the sound of. And have a bowl of op amps at home. Might try the sparkos in my Teac Reel to Reel and HD recorder now though. I haven't experimented for years

[@Karto86]

Damn, that Voena group has 67 monthly listeners on spotify, I suspect it's gonna be much more soon! Really good album!

[@SpirallingOut]

I'd like to see GR Research dip it's toes into the mini-mono amp, tube pre and DAC game with opamps like the SS3602 & SS2590. Give ChiFi a run for their money using even better components than the V3 Mono.

[@paull9989]

Danny love watching...I'm definitely not a tech guy. Would a phono pre amp contain an op amp? I have a cambridge audio alva solo. Like how it sounds but I can improve sound quality even more I'm up for the challenge

[@joshua43214]

I am oddly surprised this is your first experience with replacement discrete op-amps. They have been a huge thing over on DIYAudio for many years. Infact, one of the daughter boards on the DIYAudio M2 amp uses replaceable op-amps. SparkoS makes the upgraded output board on the Allo DAC, and it is the main reason the Allo is the king of RPi DACs.

[@RUMBLEGO1]

Me too. I'm just a casual lurker around different comment sections/forums and have heard of Sparkos op amps mentioned several hundred times now,

[@markconner5569]

I see Danny at every Audio Show I go to and have for years. I have never set up a room for a show myself and I know for a fact that he has on numerous occasions. While Dodd Audio gear may have never been produced in numbers to gain mass critical acclaim I can assure you that nobody in this conversation is an audio gear recluse.

[@tah700]

Ok I’v e watched your Video on Op Amps. First of All I’ve never heard of an op amp

[@Gassten]

i put a SS3602 in my AUNE x8 dac, it was rly nice, then i had to try the SS2590 Pro and damn its amazing!!

[@jamiefor1]

Have you tried the Burson OP Amps they are very good as well.

[@claptrap22]

Two weeks ago I placed exactly these op-amps into 2 Fosi ZA3's set up as mono-blocks for a second system and, maaaaaaaannnnnnnn.....So happy.

[@CorneliusHolden]

hell yeah, thats awesome to know. I have the same setup with an aiyima t1 pro preamp and i was thinking about about getting the sparkos for the za3s and a burson for the aiyima but was skeptical they'd make much of a difference.

[@raymondc9896]

Would be interesting to do some in depth measurements on the dac pre and post opamp change. Sometimes oscillation or negative effects can fool our brain into thinking more is there. Not saying this is the case, but wherever i change opamps i always do some testing using my cosmos e1da and scaler. Very important not to go in blind.

[@divadgnol67]

$79 today $299 tomorrow I feel a price increase coming brothers. You better jump on them

[@Jeep_on_audio]

"I find your lack of faith disturbing". There's competition and there's capitalism. That will keep your prices low. Also, there are alternatives. I have found other discrete double opamps that are also very good for less than $20.

[@nathanevans6277]

I don't think that Andrew has increased his prices in the best part of a decade. He's passionate about his creations and wants to get them into as many systems as possible. He doesn't strike me as a money-grabber.

[@richardgrant418]

Your choice of opamp depends on the sonic signature of the gear you are using it in

[@РомаСветачёв-у6ч]

Здравствуй Дэн! Пожалуйста,сделай видео о том, на что нужно обращать внимание при прослушивание музыки,чтобы понять уровень системы. К примеру что важнее детальность или построение сцены

[@joshdavis6378]

Just baught two more for my Geshelli J3 for the XLR .

[@larrydavid2807]

Man I wasted so much time researching speakers that I thought were of good value and performance. I wonder why companies go through all the trouble of researching, designing and producing speakers they throw crap parts into to limit their performance? You would think performance would draw in people who cared about sound. What a crazy business model. Danny, do you have any preferred resources to get the most out of the speakers one has in their room right now? I am thinking how to start with speaker placement, seating position and subwoofer integration? Cheers!

[@ja8020]

Going in sight unseen and sound unheard but if you and Skunkie Designs recommend them and I have never seen you so excited Danny then it's good enough for me and my Topping D50S. :):)

[@brannonmcevers1854]

They won't go in your topping

[@ja8020]

Found that out the hard way so yes you are correct as the Opamp is too tall. But with a little work with a finger sander on the housing I could make the pcb fit. I sprayed some black paint on the area and then reassembled. Soundstage and imaging got wider and taller. Bass tighter. Loving it.

[@brannonmcevers1854]

@@ja8020 i think Topping uses surface mount TI devices (opa1612 or opa1656.. I think). Very well engineered.
