I would like to buy in one go from Mauser, ok for LM4562, what do you think about RC4560PI?
As a potentiometer I found this, okay?
RK27112A0-S20-C0-A103 Alps Alpine | Mouser Italia

so do you confirm that Audiophonics sells original and non-fake material including op amps which are much cheaper than other sites?
Yes, due to covid-19 restrictions, I can only leave my 60.000 inhabitants' city for work or essential shopping reasons.
I waited for a while before writing this review.
I had filed the class D with vintage system of the german brand Gundig, brand I'm still proud of compared to other more renowned brands.
I've listened to several low-cost D-classes, the best of which was the Elipson MC1 that is made up of IcePower 125 ASX2 modules, none of those thrilled me like the vintage AB class.
According to my small, limited and subjective experience, I expected the usual class D sound from this amplifier but instead I had to change my mind.
The sound that comes out is of a medium range a little back at low volume the remedy is to raise the volume and the voices are all forward so quite good and detailed. The high end is detailed and full of air between the instrument and with a good brilliance, the cymbals have a good texture without artificial metal effect sounds, the low end at first seemed soft but listenable, then after a few rounds of listenings it became fast and controlled.
The comparison was also made with a Pioneer SA9900, Dynaco of which I don't remember the model.
As soon as I have some time, I will make a comparison with some high-end tube amps.
Hi Nerone,
I don’t know how these could possibly be genuine given the super cheap price. A single OPA627 in smd package is approximately $25. Those modules have a pair of opamps for approximately $8 total
Be careful
Well, usualy this shop has a good reputation, which is a positive.
I can't comment on these OPA627 being original or not, but one thing that could (perhaps?) explain the lowish price is that they mention used/refurbished OPA627...
Still very low price though, as Vunce mentioned... who knows...
Just thinking out loud

I'm repeating myself, but this site looks viable ....
SOIC-8 to DIP Adapter - BrownDog Adapters - 970601

Do not worry ....
This subwoofer goes down to 19 Hz!
I make it work in semi-closed, for more tense bass.
I can't wait to try with the vitaly amp !!!!
Russian Post does not seem very fast ...

Hello Vunce,
as already mentioned here, Audiophonics has a good reputation and has not had any problems until today ....
You're right about the low price ...
If I look elsewhere, the prices are higher.
For example Single-to-Dual Op Amp Adapter - BrownDog Adapters - 031101A ..
Since it costs 59.10 dollars ......
The difference is of course very big ...
But a try is worth it for the low price ....
Ciao and have a nice day
Cardone

Nerone,
for the low price I ordered it and will test it ... According to users who have already ordered it, the opa627 should be good ...
Ciao and have a nice day

@drMordor, any updates if my amp is shipped. Did you check and please let me know the timeline when it will be shipped?
Thanks

I disagree with the Italian post office, my amplifier was shipped on February 24th, it arrived at the Russian customs on March 3rd, after which I have no more news about the shipment tracking.
On March 20 it arrived at Malpensa customs, on March 23 delivered, at 13:00 it was already connected to my speakers.
So if the math is not an opinion, the Italian post office took 3 days to deliver.

Thanks for your intervention, I will wait for Cardone who acts as a guinea pig

Thanks for your intervention, this is good news if it is refurbished products, it should justify the low price.
Congratulations on your contribution in the 3d that I am following with interest on how to improve Ayima A04
