## Description

desertcart.com: 3e Audio A7 TPA3255 PBTL Next-gen HiFi Stereo Amplifier with Enhanced PFFB Professional Amplifier with 48V/5A Power Supply : Electronics

Review: Powerful and so clean sounding amplifier, Just Get It - Excellent clean sounding amplifier, just excellent. Small in size, powerful output, great build quality and good quality components - it has everything that I would want. It sounds so super clean even on running hard, amazing. I use 48v 10a psu with it and it can drive my floorstand speakers with ease. Simple but elegant, enough space between speaker connectors that I could use my thick cables without issues. Volume control is a big plus too. All this for so reasonable price, unbeatable. Highly Recommended
Review: Outstanding class D amplifier - I must say that at first I was not that impressed. But like most quality amps they have got to be burned it. Today I am so impressed with what this amp can do. I keep my volume turned up and control it at my keyboard and there is no noise. Great highs and amazing bass. What first got my attention was I was listening to one of my 24 bit FLAC recordings and this, never before herd, drum snare sound came on and I thought, “what the heck is that?” There was a crispness that I had never herd before. I backed up the recording to listen again. My jaw dropped and I knew at that moment this is a special amplifier. From that day forward I am still hearing new sounds. I played Stevie Ray Vaughn and his brothers album, Brothers the other day and discovered more new sounds. If your interest are into clear 24 bit streaming or recordings but don’t want to spend thousands then this amp is for you. Highly recommend

### ⭐⭐⭐⭐ Warm and rich but can be too forced and fatiguing.
*by T***G on December 31, 2025*

I paired this with Fosi ZD3 DAC with Elac Debut b5.2. It produces warm and rich, bassy sounds. But the highs are too forced. It provides details but can be noisy for polysymphonies and altogether fatiguing. Rock songs sounds especially bad but simpler vocals and ballads stand out. In the end I returned this in favor of the SMSL ao200 MKii (no affiliation).
