Quality with a killer price-point.

The BasX a2+ has been ideal for driving my power hungry tower's and rounding out the source component's. When using for stereo only, I marvel at the bass punch. My avr 7. 2. 2 setup with the Emotiva tower power and Avantage A8A provide an honestly satisfying home theater experience.

Clean Power at an Affordable Price

Picked up the BasX A2+ to replace a failing Adcon GFA 535II and couldn't be happier. Easily drives my Keff Q900 speakers with plenty of headroom. Pairs nicely with the PT-1 preamp I purchased a few months earlier.

Added clairty to music and dialogue

This unit added great richness and clarity to music and tv.

My retirement present to myself.

I didn’t want this review to sound like an advertisement for Emotiva products, so I waited two months before writing it. After living with this system, I can honestly say it’s the best-sounding system I’ve ever owned. For the first time, I feel like I’m listening to the music rather than listening to the gear.

Words like transparent, clean, and uncolored come to mind. The LB12s, with their front-firing ports, are a great fit for my smaller listening space. They sound wonderful and are very well crafted.

My OCD would love to add a couple of Emotiva subwoofers, but I already owned a pair of Klipsch 12-inch subwoofers, so I’m using those for now.

I’m streaming music from my iPad to the XDA-3, playing music stored on my home network as well as Apple Music, and also using a SACD player. Regardless of the source, it all sounds just amazing.

Good bang for buck

Good quality infrastructure. The blue lights coming out of the machine is not overbearing as other products. The power output is exactly as I expected it to be. Makes my kef speaker soundstage feel a little warmer

High-end audio at an affordable price

It gives an impression of a much, much more expencive device.
Build is robust and stylish, audio is natural, smooth, detailed.
It does not add any colour to the source audio.
Dynamics is great, with all the nuances still present.
I connected the amp between AVR Marantz SR6015 and speakers B&W 603S2.
Even they are difficult to drive, with impedance dipping from 8 to 3 ohm, it sounds great.
This amp has a perfect control over the speakers.
Even the oldies like "Sixteen Tons" from your countryman Tennessee Ernie Ford now sound great and detailed (source CD).
DSD sound, Symphony No. 29 from W. A. Mozart (source Amadeus SACD 2004. ) gives tons of details with great dynamics. Basses are deep, punchy, violins are high in the air, violas are deep in the soundfield with cellos up front.
This amp is all I will ever need.
Great work, Emotiva!

Audio Bulldozer with Class

I needed a dedicated amplifier that could cleanly drive my Magnepan LRS+. . . . WOW! I am hearing musical depth and complexity that I knew my Maggie's with the right match, could deliver. This amp is affordable 'grunt' with Class with beauty.

WoW

Running a WiiM Ultra and a Fiio K13 R2R with my A2+! Am really happy with the setup! The A2+ is clean and the separation is fantastic! Paired with a couple of Elac 3. 0 DB63’s and I’m hearing a whole new level of awesome!! Couldn’t be happier with this A2+!!

BasX A2+ Stereo Amp initial impressions

I'll admit I was disappointed when my Emotiva XPA-200 amp died recently and I had a less than positive experience with their sevice partner. Since I enjoyed the sound of the amp and realized I had gotten a number of years service out of it I decided to give Emotiva another chance. After checking out a number of reviews and videos it seemed like the A2+ offered the best bang for the buck so I ordered one.
Ordering was very easy and the amp arrived quickly. The amp is packaged in double heavy duty cardboard boxes and arrived encased in a nice cloth wrap.
Set up was very straight forward. I used balanced cables to connect to my Emotiva Stealth DC-1 DAC and connected my Martin Logan Aerius i to the amp with Transparent MusicWave plus speaker cables. I chose to use the signal sensing power feature and so far it seems to work fine.
Initial impression was a deeper, more "solid" low end from the Aerius than the last amp. As I'm still tweaking I'll hold off on any further review.
So far so good.

Incredible BANG for the buck.

I wanted a high quality 2 channel amp for my power hungry towers. Painstaking research led me to this Emotiva model. On-line purchase/delivery process was hassle free. Most importantly, the Basx A2+ let's my towers shine while allowing my avr to manage the 7. 2. 2 speaker array efficiently

Great

Gives my Klipsch 8060FA L/R speakers the juice they need. They sound powerful and more clear now! The trigger input works perfect when the switch on the back is set to On. I like how slim it is. It stays cool and silent.

A2+

Got the Amp delivered in good shape, no damage to the box or the Amp. Packaged nicely, very secure. Looked it over no nicks, scratches unit is in pristine condition. Hooked it up to my Pre-Outs of my Yamaha RX-V6A to power my New/vintage old and repaired McIntosh ML1C's. Does a nice job at doing that. Running the Pre-outs through an McIntosh 102 equalizer which was designed to go with those speakers, found that one on Ebay and won that one, provides a nice bass and amplification. Very pleased.

Good quality product

High quality sound , very good product , price is reasonable .

New A2 power amp

Ordered the new A2 power amp from Emotiva to replace my 15 year old parasound halo A23. was hearing hiss from the speakers. no longer as quiet as it once was. Power rating on both amps about the same. wasn't sure if the amp or pre amp was breaking down. plus some other issues were pooping up. anyway called emotiva spoke to a sales rep cause i needed a preamp with a record out capability for my cd recorder. You guys need to make one. still some folk around who like to record music on cd or tape. Anyway The A2 is smooth and has enough power for my paradigm studio 100's v2 i paired it with an advanced Paris pre. Damn, butter smooth music and loud enough for kickin it. By brother in law has Emotiva power amps and so does my next door neighbor. So you guys cam highly recommended. Plus factor you guys were having a xmas sale. Made it even better. Merry Christmas to me lol. Joe W.

Great Headroom and Control, Especially at Higher Volumes

I have it connected to a Fosi LC30, since I have a pair of bookshelf speakers and some floorstanders that I built myself. They’re not difficult speakers to drive. I previously had them connected to a Dayton HTA200, and while it performs quite acceptably, the difference became noticeable mainly with the floorstanders.

There’s less compression when I listen at higher volumes—or rather, I keep turning the volume up because it always continues to sound good. The bass response is more precise, and I would say the mids are cleaner. That said, the difference is still subtle. The overall character of the amplifier isn’t drastically different.

I also have a Fosi Class D amplifier that I use for testing, and… after spending time listening with the Emotiva, I can’t stand going back to it.

I now have much more headroom, and it shows. The dynamic range is excellent. I’m very happy with it. I’m using a WiiM Ultra as my DAC.

BasX A2+ Amp

Started with a BasX A300, then BasX A2, and now BasX A2+. . My sons acquired my previous 2 music systems!! Now I buy with no fears of being asked for!! I absolutely love Emotiva Amps, PERIOD!! The BasX A2+ is my favorite of all Emotiva's BasX Amps!! Cannot find a better amp for the same amount, anywhere!! Using it to power my XT2 speakers and they ROCK !! I will never buy any audio equipment except from Emotiva. . .

Very satisfied with my amplifier

Very satisfied with my purchase delivery was quick and convenient easy and I like the capability of the amplifier I like the automatic cooling fans. I like the 500 damping capability I like the automatic standby mode and I’ve hooked it up with my S booster which I took me 5 1/2 months to receive but it kicks ass. It really sounds great. I highly recommend recommends people by both maybe Eva should make a S booster so I’m enjoying it and I’m putting it through which paces I’m running to Jensen model five in parallel with the 2JBLL 19 in my man cave and plan on buying a couple of more speakers for my work room, which is right behind the man cave and I ain’t got that all sorted out yet but very happy with my purchase. Thank you Kevin.

Adding this amplifier to my

Adding this amplifier to my system has made a huge difference. I already enjoyed my TA-100, CD-100, T-Zero Towers. This is a significant upgrade and goes well with other upgrades in cabling and the addition of a streamer.

The Emotiva BasX A2+ sounds great and has plenty of power to drive my Cerwin-Vega XLS-15s and Technics SB-G900 speakers, but I’ve had some frustrating issues. I’m running a Fosi Audio S3 streaming preamp with Cable Matters XLR cables and a 12V trigger. The AUTO ON feature randomly cycles the amplifier in and out of standby, even with nothing plugged into it. I spent quite a bit of time troubleshooting, disconnecting the XLR cables, trigger, speaker cables, and eventually unplugging the Fosi entirely. The amp still turned itself on with nothing connected. Switching to ON fixed that issue, and the 12V trigger works normally. More recently, the amp went into protection mode during a high-volume session despite not being hot. I checked the wiring and connections, restarted it, and everything worked again. Excellent sound quality, but these reliability issues are disappointing.

Excellent customer service

The A2+ is everything I expected. Works well with my Maggies LRS+. Highly recommend and my questions were answered by a real person.

Amazing quality for the price!

I'm using this amp with a WiiM Ultra and Martin Logan Motion XT B100 bookshelf speakers. The sound quality is stellar! The build quality is superb. I think it's safe to predict many years with this amp. I will definitely be a return Emotiva customer.

Trustworthy products!

I own a basx a4 and now also this a2+. I felt totally confident buying another Emotiva amp. Works like a charm as expected. Great stuff at a reasonable price!

Sounds great and stays cool!

This amp pairs perfectly with my Emotiva preamp. It sounds flawless and even after playing for many hours on end does not even feel warm to the touch. I am very pleased with this purchase.

Excellent
