Experience audiophile-level performance with the dual TI TPA3255 amplifier chips in PBTL configuration. Our advanced Post-Filter Feedback (PFFB) technology delivers 0.0004% THD, 104dB SINAD (at 5W), and 125dB SNR—minimizing distortion and ensuring consistent clarity across all speaker loads. Push 140W@8Ω or 250W@4Ω per channel for powerful, dynamic sound that brings music, movies, and podcasts to life with deep bass and precise detail—ideal for home audio, bookshelf speakers, and desktop systems. - Pure Analog Signal Path & Flexible Inputs for Home Theater. Enjoy uncompromised sound with direct analog input (no ADC conversion)—preserving the natural warmth of your audio source. Switch to volume bypass mode to eliminate signal interference, creating a pure chain from DAC to speakers. Supports XLR/¼" TRS balanced and RCA single-ended inputs (with gain control), plus auto power on/off and signal sensing for energy efficiency—perfect for home theater amplifiers, passive speakers, and HiFi stereo setups. - User-Customizable Design with Swappable Op-Amps for Personalized Sound. Tailor your listening experience with swappable op-amps (stock OPA1656/OPA1612). Compatible with DIP8 dual discrete op-amps like Sparkos SS3602, MUSES02, OPA2604, and Burson V5i/V6/V7, it lets you fine-tune sound signature to match your tower speakers and preferences. The user-centric design adds flexibility for HiFi enthusiasts and casual listeners alike—making it a top audio component for serious setups. - High-End Components & 6-Layer PCB for Maximum Performance. Built with audio-grade capacitors, flat-coil inductors, low-noise op-amps, and TI power management ICs—every part is selected for superior sound and reliability. The 6-layer PCB design reduces interference and optimizes signal flow, ensuring the amplifier maintains peak performance even during extended high-power use. This is the next-gen amplifier choice for demanding home audio components. - Efficient Full-Body Heat Dissipation for Stable Operation. Stay cool under pressure with a full-body heat dissipation system. The dual TPA3255 chips are mounted on a large heatsink integrated with the chassis, while bottom and dual-side ventilation holes boost airflow. This design prevents overheating, guaranteeing stable, distortion-free output whether you’re cranking up the volume for a party or enjoying a long listening session with your desktop or home theater system. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0F8HG4KKN | | Best Sellers Rank | #46,820 in Electronics ( See Top 100 in Electronics ) #252 in Audio Component Amplifiers | | Brand Name | Generic | | Customer Reviews | 4.9 4.9 out of 5 stars (22) | | Included Components | A7 Power Amplifier x1；48V5A Power Adapter x1；User Manual x1 | | Item Dimensions | 6.69 x 6.61 x 1.81 inches | | Item Weight | 1 kg | | Manufacturer | 3eAudio | | Material Type | Electronic Components | | Maximum Output Power | 250 watts | | Maximum Supply Voltage | 48 volts_of_direct_current | | Minimum Supply Voltage | 48 volts_of_direct_current | | Model | A7 With 48V/5A Power Adapter | | Mounting Type | Freestanding | | Number of Channels | 2 | | Number of Items | 1 | | Output Power | 250 watts | | Part Number | A7 | | Unit Count | 1 Count | | Voltage | 48 volts | ## Product Details - **Item dimensions L x W x H:** 6.69 x 6.61 x 1.81 inches - **Manufacturer:** 3eAudio - **Maximum Supply Voltage:** 48 volts_of_direct_current - **Minimum Supply Voltage:** 48 volts_of_direct_current - **Voltage:** 48 volts ## Images ![3e Audio A7 Next-Gen HiFi Stereo Amplifier | Home Theater Amplifier | TPA3255 Chip 2x250W PBTL with Enhanced PFFB | 48V5A Power Supply for Bookshelf Speakers - Image 1](https://m.media-amazon.com/images/I/31Qh2YNbyCL.jpg) ![3e Audio A7 Next-Gen HiFi Stereo Amplifier | Home Theater Amplifier | TPA3255 Chip 2x250W PBTL with Enhanced PFFB | 48V5A Power Supply for Bookshelf Speakers - Image 2](https://m.media-amazon.com/images/I/314P7pkfjEL.jpg) ![3e Audio A7 Next-Gen HiFi Stereo Amplifier | Home Theater Amplifier | TPA3255 Chip 2x250W PBTL with Enhanced PFFB | 48V5A Power Supply for Bookshelf Speakers - Image 3](https://m.media-amazon.com/images/I/31FUqh6cb3L.jpg) ![3e Audio A7 Next-Gen HiFi Stereo Amplifier | Home Theater Amplifier | TPA3255 Chip 2x250W PBTL with Enhanced PFFB | 48V5A Power Supply for Bookshelf Speakers - Image 4](https://m.media-amazon.com/images/I/3102oviHNaL.jpg) ![3e Audio A7 Next-Gen HiFi Stereo Amplifier | Home Theater Amplifier | TPA3255 Chip 2x250W PBTL with Enhanced PFFB | 48V5A Power Supply for Bookshelf Speakers - Image 5](https://m.media-amazon.com/images/I/41XRlls5-QL.jpg) ## Available Options This product comes in different **Model** options. ## Frequently Bought Together - 3e Audio A7 Stereo Amplifier Home Audio HiFi with Enhanced PFFB TI TPA3255 Professional for Desktop Home Theater with 48V Power Supply - FosPower (2 Pack) 2 RCA M/M Stereo Audio Cable [24K Gold Plated | Copper Core] 2RCA Male to 2RCA Male [Left/Right] Premium Sound Quality Plug - 3FT - S.M.S.L SU-1 MQA MQA-CD Audio Decoder AK4493S XU316 768kHz/32Bit DSD512 Hi-Res DAC --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/726394520-3e-audio-a7-next-gen-hifi-stereo-amplifier-home-theater](https://www.desertcart.tn/products/726394520-3e-audio-a7-next-gen-hifi-stereo-amplifier-home-theater) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-27*
