    BasX: The Foundation of a Superb Audio System

    The goal of putting together an exceptional audio system is to enrich your life with outstanding sound. It isn’t about spending a lot of money, or about fancy knobs and jewel encrusted remote controls; it’s all about playing the music. As a leading manufacturer of home audio equipment, we’ve noticed that a lot of people still don’t have high-quality audio in their lives. Some folks don’t have the budget to buy good equipment, while others don’t have the time to spend trying to figure out how to use it – and that’s exactly why we developed our new Emotiva BasX products. Our BasX components combine great sound quality, a carefully chosen set of genuinely useful features, and rock solid performance, with a simple yet elegant design.

    This unique combination allows us to offer a combination you just can’t find anywhere else – great sound and great value. All of the components in our new BasX line are priced to be within reach of every music lover. You don’t need to be rich to afford them, and you don’t need to be an engineer to figure out how to use them. They’re carefully crafted to give you many years of reliable and trouble-free service, and they’ll look great in your living room or on your audio rack. You can build a complete music system out of our BasX components that will give you a true audiophile listening experience. Or try adding one or two BasX components to round out your existing audio system. Great sounding audio doesn’t have to be expensive or complicated.

    BasX Simplicity

    While the BasX A-150 offers lots of performance, you won’t need an advanced degree to install and use it, and you won’t need to rewire your home. The BasX A-150 ships with a removable heavy-duty industry standard IEC power cable. Just plug it into an outlet, connect it to your preamp or processor and your speakers, and you’re done. Your BasX A-150 will figure out your line voltage automatically, and its speaker outputs are heavy-duty five way binding posts that accept bare wire, banana plugs, or spade lugs. We’ve used industry standard connectors, so you can upgrade the power cable or your speaker wires if you like; the BasX A-150 doesn’t really need all that fancy stuff, but it’s ready if you decide you want to add it later.

    BasX Quality

    The BasX A-150 is built to last, with a heavy duty steel chassis, solid milled aluminum faceplate, and high-quality parts and construction throughout. We expect you to enjoy your BasX A-150 for a long time – and we back that up with a full three-year warranty.

Very Nice.

All the good reviews are correct, this is a very nice amp. Very sturdy and well built. What impresses me is that I can have it on for three or four hours during the summer with the air conditioning off and this amazing amp is still cool, maybe a tad slightly warm if that. The sound is warm but can be impactful. I have a pair of Martin Logan bookshelf speakers with their wonderful air motion tweeters that sound amazing but with the wrong amp can sound too strong at times, the A 150 tames the highs so they don’t sound too strong but brings out the instruments so they sound very natural. The mids and bass are very good perfectly matched with the highs. One of the best audio investments I’ve made.

Within minutes I was disappointed that I waited as long to add this as I did.

I have been running Emotiva T1 speakers for a year. I knew my integrated amp was under powered, but my listening area is small so I figured I could make up for it with volume. As it was, the speakers sounded great, or so I thought. Within minutes of hooking this up and putting on my favorite record I felt like a veil had been lifted to reveal what my system was capable of . Everything was far more present. Bass woke up with the speakers. No placebo here; I had to spend some time adjusting my subwoofer output because it became too much when added to what the speakers were producing. Guitar strings sounded crisp during interludes, and blast beats punched, oh did they punch. I won't pretend I know a lot of audiophile terminology or try to impress you with my knowledge. I will simply state that for my setup this power amp made a world of difference, and helps their speakers shine far better than my integrated amp ever could. Truth is, I ordered a new turntable while this was in transit. This made such a big difference, I honestly don't give a fudge about the turntable upgrade. Had I got this in first, I may not have even bothered with the new turntable.

A150

I paired this amp with the PT100 preamp and Whafedale Diamond 230 speakers in my little man cave ( 10x12 ) room.....WOW is all I can say...It’s everything I wanted..It’s such a warm and natural sound coming from my speakers..I’ve not had to touch the tone controls on the preamp...For the money u can’t beat this amp and preamp. It has a sound that would make you think it cost a lot more..

Truly great value.

The most amazing thing to me about all the Emotiva products I own (23 at this point) is the value for the dollar invested. I have heard amazing systems over the years and have wished that I owned some of them. But in my world, a house, a car, the basics, was somehow a higher priority. Being able to obtain such high performance in affordable products is such a joy. If I were designing them, I would change the user interface process, but ultimately the sound is all that matters and Emotiva delivers in aces.

Sweet Power Amplifier.

I have been a budget audiophile for 50+ years and I am amazed at the smoothness and clarity of the A-150 power amp. At first I wanted the A-300 but I thought let me try the A-150 for a few weeks and see if it would do the job and I could always moved up to the A-300. No need to move up, the A-150 is plenty of power to make my Monitor Audio B2's sound better than ever. I am using the A-150 with an all tube preamp and wow. Believe me it sounds as good to me as anything I have ever heard. In my small dedicated music room I am 100% satisfied. Thanks Emotiva. PS-I have bombed Emotiva with many questions and they were helpful, quick with responses and very professional. Highly recommend. If you are in doubt you always have a 30 day trial period. No harm no foul. KEEP UP THE GREAT WORK EMOTIVA. I'm a born and raised Tennessean and I am proud to have a company like Emotiva establishing their residence in Franklin. A+
