Thanks it's actually Wonderful when someone reviews products on RUclips with a system that can actually produce true details of recordings. Very Rare!!! I need a lower profile OpAmp for my application in the Douk Q11 DAC with tha upgraded power supply
Witam Pana. Fajnie się ogląda i słucha filmików. One comments which Audio Maniacs should be aware off is voltage requirements of presented OPA, when 4 pcs is required. I had MuzgAudio OPA also Polish brand but my Phono Stage failed to start at all after OPA roll off. I do not faced such problems when instaling 4 x Muses03 or OPA627. So please, everyone be carefull and read closly specifications to not waste Your time and money. Kind regards from Gdynia City
Yes, ICs do require a lot less current to start and work properly. If the device was designed for rolling opamps it will usually have better power delivery capabilities, but if that's just random replacement, things can be different. That's why I think it would be useful for manufacturer to maintain a list of devices confirmed to be working properly with a specific opamp - same goes for Akliam. Dziękuję! :)
Yes, You are right, such a list would be very helpfull. However to modify sound also roll off of the fuses is very interesting subject. I have started from Aucharm Red fuses in my system and I was very happy regarding better sound, but presently using Synergistic Research fuses. Aucharm adding very nice midrange and analog sound, SR adding all frequency like you would add booster equalizer to your system, worth to try... Pozdrawiam serdecznie
@@KatarzynaJachimska I had a phase when I was replacing all fuses everywhere :) Nowadays I'm changing it only in sources like DACs, as the results are strongest, and good fuses tend to be really, really expensive :(
I’d avoid touching any pins or any conductive materials on circuit boards. While not every component is sensitive to electrostatic discharge, it’s a good habit to get into. Especially in low humidity/high static environments. If you are building circuits and need to touch the parts, that’s different and you can wear ESD straps tied to ground for component protection.
Yes, thats a good practice. Though the last time I actually have seen something damaged by esd was in 90ties, It hink all (or most of) semicondustors have protections built in now. But you are right, its a good habit to observe that precautions SO EVERYONE: DONT DO AS I DID AND DONT PLAY WITH THEM BAREHANDED!
I wish somebody would just make a bunch of wave files recording a system playing using different op amps so one can simply download the waves and see if there is a discernible difference.
Unfortunately the sound is changed as it passes through, To be more specific the blue LED took almost 60 years to create after the Red and Green but that breakthrough led to the flat screens we use today. But on the note of wave files Yamaha DSP does that I purchased there first system in the early 90s now SMSL has a DAC with 11 OP-Amps
That is my question too. I use a bunch of the Akliam LC2 (now LC5) discrete opamps and they sound better to my ears than the SparkoS. Bought on AliE, 20 euro!
Both are class A, so they are similiar. LC5 are a bit airier, Staccatos softer and more analog sounding, so it boils down to personal preference and matching with specific equipment. I will do a video on all of my opamps from my collection
Can you please create a summary video of where to switch op amps along the signal chain? DAC? Pre? Amp? Which component to start with first when experimenting? Let's say the DAC has a discrete OA, should I use a relatively neutral one in the amp? It would seem like overkill to just put sparkos or bursons or staccatos in every component. Help me map out my op amp rolling journey (rabbit hole). A lot to ask, I know. Sorry.
@@murshedrahman8399 Hi! That's actually on my list of to-do-videos! Along with the one about choosing the upgrade path for power cords, interconnects etc! Stay tuned! (Start with the source, that's always the best place, and in DACs that have LPF and I/V replaceable start with I/V and move down the chain - I'll cover more in the video)
You can order (with large orders!) factory matched batches. These are ordered by 1000 matching pieces, and then there's manual pair matching, hand picking transistors for specific sets. And then there's thermal coupling, but that's the icing on the cake. That probably also partially explains the price, that sized order do not come cheap...

Have you considered wired dip8 adaptors?
I really appreciate your evaluations of these clones. Very interesting!

Thank you!
Interesting...could you use these in a crown xls class D amp ?
As long as there is enough space to fit them inside, yes. There are also other geometries available, Ive seen the horizontal version

That's obsolete advice now days

The problem is youd need qulity ADC for that, like E1DA Cosmos. But I like the idea, good thinking!
How they compare to akliam opamps? I believe are better?

Are those adjustable bias pots? If so, I’m surprised they didn’t put a drop of paint on them, to preclude the setting from changing.
It will not change by itself, but I like the idea, its a simple precaution!
different folks different strokes i've tried both staccato vs sparkos I liked the sparkos more, the staccato's sounded to smooth for my liking
Yes, at this level its highly about personal preference and equipment matching to get the best combination possible
Would it work with Fosi ZA3 or V3 monos?
@@Grooverski AFAIK yes, but you have to check for room inside
@@k4syx Thanks a lot
Can 4 single OP work same with adapter?
Im not sure I get what you mean, can you explain?
@@k4syx i have two OSH-S - Single Discrete Opamp, can i use them as Dual with adapter?
@@andrews4379 Ok I get it now :) yes you can as long as there will be a room for them
any sound test?
No, doesnt make sense to do that on YT untill I'll get some really good microphone.. on my list.
@@k4syx What do you think.. which one speakers will fit best for them?
@@andrews4379 These are made for amplifiers and DACs, I would place them in neutral and colder sounding stuff
friend of mine swears by these, says he like them better than sparkos ss3602...guess ill have to get some now lol
Better than Sparkos. Prooven
They are seriously good and they are used in some German hi-end equipment as a base one of components
Another great video ! Would it fit Semibreve DA50 and how much it would improve on DA50 over LC5?
I'm concerned if these things are even matched pairs. I mean aren't most transistors generally +/- 10% on current gain (or worse?)
You can order (with large orders!) factory matched batches. These are ordered by 1000 matching pieces, and then there's manual pair matching, hand picking transistors for specific sets.

I prefer Muzg Audio Jfet also from Poland
@@MoizAudio May try to get these too!
@@k4syx trust me better than staccato. I ordered 10, so you have to wait..haha
