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

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

The 3e Audio A7 is crystal clear, dynamic, powerful, and detailed—kinda blows my mind. It’s hands down the best amp I’ve ever had in my system. Worth every penny, no question. I was thinking about upgrading my JBL Studio 530s, but now, I’m not so sure I need to. This A7 is a major upgrade for me, makes my speakers sing in a way I didn’t expect. All amps don’t sound the same. I’m not some audiophile, too cheap for that fancy stuff, but I can tell the difference.I had a little issue with my setup, thought it might be the A7 at first. So, I emailed 3e Audio support, and wow, they got back fast. They were super responsive, way above and beyond the call of duty. Turns out it was my setup messing up, not the amp. I really appreciate their patience and how they stuck with me.

If you read my review of the A5 unit, it had a design flaw which prevented the unit from being powered down without the power automatically going back on again after a few seconds.... Due to the "standby" mode being too sensitive and powering the unit back on, even with the absence of audio signal.There is a workaround with the A7, which I was not able to do with the A5: ***Be sure the volume knob is turned all the way down before doing this. Disconnect the input cables from the unit, and temporarily install "shorting plugs" at the RCA inputs. (This makes the unit "see" absolutely no audio signal in "standby mode" and hence won't trigger the unit to power back on.) Power the unit down as usual by holding down the knob. (The power won't trigger back on with the shorting plugs in place.) Now you can "disable" the "standby mode" by holding the volume knob while powered down, wait for the "RCA" LED to flicker. (Without the shorting plugs, trying to disable the "standby mode" doesn't work because the unit powers back on before the "disable procedure" is completed. This was what made me unable to disable "standby mode" on the A5 under any circumstance.) Then remove the shorting plugs and re-connect the unit as normally set up. The unit will now power down without turning back on.Like the A5, the A7 has exceptional sound quality for an inexpensive Class D amplifier. What stands out about this amplifier is the "clarity" in the upper registers, and the absence of "Class D" sound, heard in other inexpensive amplifiers. (It should more like a Class AB amplifier, if you will.)I would upgrade the review rating for both units to five stars if the "default" is updated with the "standby mode" being disabled, or if the trigger threshold for powering back on wasn't so sensitive. (The "standby mode" can be enabled again, but then the "shorting plug" procedure stated above would still be the only way for me to disable it again.)

I got these to pair with my avr for my front right left speakers. Works well for my speakers that go down below 4 ohms in a good chunk of the lower frequencies. Priced very competitively against other high quality amps.If you need more power youll need a 48v 10amp power brick. Should be an option to choose from.

This is an excellent amplifier in every way. Great value.

My favorite Class D stereo amplifier. With better heat dissipation and twin Texas Instrument Amplifier chips surrounded by premium grade components, 3E Audio (a quality OEM manufacturer of subcomponents for other manufactures) has an engineered a winner. This preforms admirably against my Topping PA7 in all aspects at 1/2 the price. This design uses a high current and respectfully high wattage circuits to drive almost any speaker out there with clean, dynamic and well imaged stereo audio. Audio Science Review recommended for all the right reasons. A really, really good stereo amplifier at the top of the budget mountain.
