Review: first time switching op amps and all is well - these chips made my duok P1 Plus sound better and they are a bargain. there is a youtube short that says these are fake but the op amps are built to specs and I don't think the person auditioned them and they are being picky-picky. Review: Good for my cmoy - It works great in my old altoid's CMOY. It adds a nicer bass kind of sound to my headphones. From my point of view it really shines best with my grados and dt990 pro 250 ohm headphones. Totally worth it. ## Features - Item Condition: Brand New - Quantity: 5 Pcs - Actual item as shown in photos - Random send the part number - NOTE: Kindly compare your original item with the photos provided for the listing to make sure that you are purchasing the correct part. we don't provide technical assistance please make sure you are familiar with the product before purchasing. apologize in advance. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08QJHSSKZ | | Brand Name | Todiys | | Customer Reviews | 4.3 4.3 out of 5 stars (20) | | Item Weight | 10 Grams | | Manufacturer | Todiys | | Material Type | Copper | | Model | OPA2604 | | Mounting Type | Surface Mount | | Number of Channels | 2 | | Package Type Name | DIP | | UPC | 788505983089 | ## Product Details - **Brand:** Todiys - **Manufacturer:** Todiys - **Mounting Type:** Surface Mount - **Number of Channels:** 2 - **Package Type Name:** DIP ## Images ![New 5Pcs for OPA2604AP OPA2604APG4 DIP-8 Dual FET-Input Low Distortion Operational Amplifiers IC OPA2604 - Image 1](https://m.media-amazon.com/images/I/51zjuPW+H6L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ first time switching op amps and all is well *by J***S on September 13, 2025* these chips made my duok P1 Plus sound better and they are a bargain. there is a youtube short that says these are fake but the op amps are built to specs and I don't think the person auditioned them and they are being picky-picky. ### ⭐⭐⭐⭐⭐ Good for my cmoy *by P***N on February 20, 2026* It works great in my old altoid's CMOY. It adds a nicer bass kind of sound to my headphones. From my point of view it really shines best with my grados and dt990 pro 250 ohm headphones. Totally worth it. ### ⭐⭐⭐⭐ Marvelous Sound *by J***T on September 26, 2025* These were the third op amp I tried in my Douk amp, and easily the best sounding. I did have a failure of one chip. While playing at high volume there was a sudden metallic, percussive noise from the right speaker. Later I realized there was a steady low level hiss from that speaker. I swapped out both op amps, which fixed the noise. All is well, so far. I do realize that the authenticity of these chips is in question so time will tell. They do sound marvelous, rich and detailed. ## Frequently Bought Together - Todiys New 5Pcs for OPA2604AP OPA2604APG4 DIP-8 Dual FET-Input Low Distortion Operational Amplifiers IC OPA2604 - Bridgold 2pcs LM4562NA LM4562 Dual High Performance, High Fidelity Audio Operational Amplifier IC，DIP-8. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/284546824-new-5pcs-for-opa2604ap-opa2604apg4-dip-8-dual-fet-input](https://www.desertcart.vn/products/284546824-new-5pcs-for-opa2604ap-opa2604apg4-dip-8-dual-fet-input) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-21*
