MUSES02 is currently $44 each plus shipping at Mouser. Anybody know where to get genuine MUSES02 instead of fakes at a lower price? 4 x 44 + 8 shipping = $184 for four op amps plus tax so ~$200. Not willing to pay that.
Anything labelled to be "for audio" costs too much except when they are meant to be used by the industry. You could simply use another good opamp. OPA1642 and OPA1656 are both around 3 Euro.
OPA1612, Muses 8820...
By the way, I prefer 02 sound over other OPA even if price difference is taken into account. 8820 is 85% of Muses02 at fraction of the price, but 02 is still better to my ear.

Mouser has usually been the best price supplier of the Muses 0-series opamps. And they are genuine.
What is your application?

Actually asking @Never Get Old , however it’s always nice to hear from people who have used them with good effect!

A cheap Chinese DAC that cost less than $200. The 4 x OPA1612 in it right now sound ok. The 4 x fake OPA1612 in another identical one sound even better, surprsingly good in fact, but they required that I make tiny heat sinks for them because they run so hot. That little DAC sounds great now, after adding heat sinks and running it through my Furman PL-8C power filter.
I'm going to try the Sonic Scientific Oracle II - 02 based on a recommendation: https://www.facebook.com/sonic.scientific Only $6.50 each from one of the two authorized sellers: https://www.aliexpress.com/i/2251832834352133.html?gatewayAdapt=4itemAdapt

I just discovered that the Oracle II-02 and its designer appear in a video from Burning Amp Festival 2022, the fifth video down, "Project Displays."
https://burningampfestival.com/videos/
My four Oracle II-02 are scheduled to arrive Monday, from one of the two authorized sellers.
I did get them, and I have listened to them in comparison to others for some time now. My impression so far is that they are not ideal in this particular application. That is not to say that they would not work differently in different applications.
I can say that they run the coolest of the op amps that I have tried in this application. I also can say that they sound "analog" in this application, with no "digital glare" added.
Unfortunately, I also feel that they have weak and lifeless bass and sub-bass when listening to live blues performances. See this thread for more about the music:
https://www.diyaudio.com/community/threads/iso-audiophile-blues-and-jazz-on-cd.399588/
The bass lines are there, but I feel that Oracle II-02 is weak in comparison to Burr Brown 2604 (genuine not fake) and the Chinese fake OPA1612 labeled "OVII" (with my own custom heat sinks added PLUS ventilation perforations because the OVII run HOT) that came with two of the units. Oracle II-02 are smoother than the genuine OPA1612, but with the same issues that I am citing here.
I also feel that the top end is rolled off with Oracle II-02 in this application.
If you have an application where you feel the bass is boomy and needs to be lessened and cleaned up a bit, and also the system is bright and hard at the same time, then maybe Oracle II-02 would be a good option. Again, it would depend on the application I suppose. So far, they rank last on my list of op amps in this application.

Price seems too good to be true.
I have had good experiences with this seller on other items: https://www.aliexpress.us/item/3256803102972631.html

Looking at pictures people posted in reviews, these are not original.
Aliexpress is insanely dubious platform. If you want original chip, get it from mouser or any other verified retailer.
If you do buy from dubious places, one way you can check is quite easy, muses legs are copper. Very very pliable. And top print is quite obvious.
team2 arrived yesterday and the first thing he does is advertise for an ali salesman, it doesn't leave much doubt about his motivations for coming here.
It's silly that people want cheaper products that are way below market price, and expecting them to be genuine. Then cry (or even worse convince themselves in a lie that it is), and in the end purchase proper item from a proper retailer, spending more money, nerves and time in the process....
From the seller's picture, the round indent is located between the first and second leg, and from my experience opamps with this misplaced indent tend to be fakes.
It's supposed to be right on the first leg and nowhere else.
P/s: Also the fakes usually have a flat "stamped" circle, and not a sort of "rounded" indent.
I was looking at buying a pair of muses02's for less than 50 or 60 pounds a pop. I'd looked at many genuine vs fake posts on the net and looking at the ones sold by the seller on aliexpress and a reviewer stating them to be original, as he has originals to compare them to from Japan thought I'd take a chance on them. Someone else kindly directed me to a possibly better option on aliexpress. That's all bud. I've been reading up for ages on pre amp mods e.t.c
