Item delivered as single it's advertised dual and pictures are 2 units displayed additionally in pictures there is black adaptor to connect to mainboard is visible it's not delivered I ordered one more to make it dual but this time ship it correctly as advertised in picture with full accessories

Ok these came packed in a small cardboard box and all have arrived undamaged so far. I wouldn't say great packing (Anyone who has purchased on Ali exp know good packing) I can definitely tell the difference in my sound. Everything is a little louder and much more detailed.. very nice soundstage. I have now purchased 4 of these little guys, 2 fir my Fosi ZD3 and 2 fir my Fosi ZA3. Holy freaking wow this sounds good. I noticed the biggest improvement when I plugged into the ZD3, possibly because it's the first chain. I am planning to purchase 2 of these 3602's from Sparcos to see if there is a difference and if so how much. I'll try to post my findings on here. But at this price point you really can't go wrong guys!!

I chose this dual operational amplifier to upgrade my audio setup. It comes in an 8 pin DIP compatible package, which makes it a straightforward replacement for many standard sound op amps. The installation process is simple, and it fits easily into the socket of a decoder or preamplifier. The sound quality improvement is noticeable right away. The audio stage feels much wider, and there is a clear separation of instruments. The overall sound texture is thicker and warmer without losing any of the high end details. It balances the musicality well, making long listening sessions very pleasant. It works well across different devices, including music players and headphone amplifiers. If you are looking to upgrade your digital to analog converter or preamp, this module offers a significant and satisfying improvement in sound performance.

The opamps were recieved damaged as they were shipped in a plastic envelope rather than in a box. I contacted the seller and the opamps were replaced promptly. I am happy with the customer service and the product.

I don’t know where to begin. Tried one returned it and re ordered another and returned that one. Save your money.

Using a pair of them with burson audio vivid V6'S in a pair of fosi audio mono v3's, very happy with them. Highly recommend
