Picking the right power amplifier doesn’t have to be complicated. Emotiva keeps it simple with two clear paths: BasX for maximum value and everyday performance, and XPA for reference-grade, audiophile muscle. Each series targets different systems, listening priorities, and budgets—whether you’re building a home theater amplifier stack from AVR pre-outs or upgrading a dedicated stereo amplifier rig.

Below, we break down what sets BasX and XPA apart, line up key models head-to-head, and help you choose the amplifier that fits your room, speakers, and goals.

How to Choose an Amplifier

When selecting an amplifier, consider the following:

• 
  • Budget: Determine how much you’re willing to spend.
• • Audio Needs: Think about your listening habits and the quality you desire.
• • System Complexity: Assess the complexity and power needs of your audio system.
• • Room Size: Larger rooms might require more powerful amplifiers.

Understanding these factors will help narrow down your choices and ensure you get the best fit for your setup.

BasX Amplifiers: Quality Sound Without the Price Tag

Looking for big sound on a sane budget? Start with the Emotiva BasX Series.

These affordable power amplifiers focus on clean, reliable performance and truly user-friendly operation—perfect for budget audiophiles, stereo rigs, and home theater amplifiers fed from AVR pre-outs.

Our new BasX Plus models step it up with balanced XLR and unbalanced RCA inputs, giving you flexible connectivity with AVRs, processors, and DACs.

Here are a few popular models to explore:

• • BasX A2+ Stereo Amplifier: Delivering 160 watts per channel into 8 ohms, this two-channel amplifier is perfect for a dedicated stereo or 2.1 music system—or for taking over your AVR’s front Left/Right channels in a 5.1/7.1/Atmos setup—for greater headroom, control, and clarity.
• • BasX A3+ Three-Channel Power Amplifier: With 140 watts per channel into 8 ohms, this three-channel amplifier is ideal for powering your front Left/Center/Right speakers in a 5.1, 7.1, or Dolby Atmos/DTS:X home theater, taking the load off your AVR for cleaner dynamics and headroom.
• • BasX A7+ Seven-Channel Power Amplifier: For a full 7.1 bed layer or a 5.1.2 Atmos rig, hand the workload to the A7+ via your AVR’s pre-outs—seven channels at 90W into 8 ohms each—so your system runs cooler, hits harder, and stays clean at reference.
  

The BasX series is ideal for enhancing your home audio experience without a hefty investment. It’s perfect for casual listeners and those building their first audio system.

XPA Amplifiers: Premium Performance

Serious listeners and home theater builders choose the Emotiva XPA Series when reference-level sound is non-negotiable.

Engineered for clean, high-current power and a vanishingly low noise floor, these audiophile power amplifiers deliver explosive dynamics, fine detail, and iron-fisted control—exactly what you want from a home theater amplifier or stereo power amp.

Here's some of our standout models to consider:

• • XPA-2 Gen3 2 Channel Audiophile Power Amplifier: With 300W per channel into 8 ohms, it’s a natural fit for reference-grade stereo or a punchy 2.1 music rig—and a killer upgrade for taking over the front Left/Right in a 5.1/7.1/Atmos theater via your AVR’s pre-outs for extra headroom and grip.
• • XPA-3 Gen3 3 Channel Audiophile Home Theater Power Amplifier: At 275W/ch into 8 ohms, your L/C/R finally get the muscle they deserve. Drop it into a 5.1, 7.1, or Atmos rig via pre-outs and hear cleaner dialogue, bigger impact, and effortless headroom.
• • XPA-7 Gen3 7 Channel Audiophile Home Theater Power Amplifier: Seven channels, 200W each into 8 ohms. Drive a full 7.1 bed layer or a 5.1.2 layout from your AVR’s pre-outs—and keep the biggest moments huge, composed, and strain-free.

XPA-DR Amplifiers: Ultimate Audio Experience

If you’re chasing true reference sound, our XPA-DR Differential Reference amplifiers are the move. They combine massive current with vanishing noise for clean, effortless dynamics in real rooms with real speakers.

• • XPA-DR1 Differential Reference™ Monoblock Power Amplifier: A monoblock amplifier with 650 watts RMS into 8Ω. Use a pair for reference-grade stereo, power a single demanding center channel in a large theater, or drive ultra-low-sensitivity towers without breaking a sweat. Ideal for audiophiles who want the most headroom and control.
• • XPA-DR2 Differential Reference™ Two-Channel Power Amplifier: Two channels at 550 watts per channel into 8Ω. Perfect as a stereo power amplifier for high-end 2.0 or 2.1 music systems. Also a great fit for taking over the front Left/Right in a Dolby Atmos or DTS:X home theater, letting your AVR or processor handle surround and height channels.
• • XPA-DR3 Differential Reference™ Three-Channel Power Amplifier: Three channels at 450 watts per channel into 8Ω. Built to anchor your L/C/R in a premium home theater amplifier stack. Pair it with a separate amp for surrounds and heights, and you’ve got a powerful, quiet foundation for 5.1, 7.1, or 5.1.2 systems.

The XPA-DR Series suits serious listeners who want audiophile dynamics, rock-solid imaging, and effortless volume. Big power. Precise control. Music and movies that feel alive.

Modular and Upgradable Design

One of the standout features of our XPA series amplifiers is their modular and upgradable design. This allows you to customize your amplifier to fit your specific needs. Whether you start with a two-channel and later decide to expand, Emotiva can upgrade your amplifier for you, ensuring your system grows with your needs.

Model Comparison: BasX vs. XPA

Let’s compare these models head-to-head to highlight their differences:

• • Power: The XPA-2 (300 watts per channel) and XPA-3 (275 watts per channel) significantly outperform the BasX A2+ (160 watts per channel) and BasX A3+ (140 watts per channel).
• • Technology: XPA amplifiers feature advanced technologies like the Soft Switch™ Class H power supply, which enhances efficiency and performance. BasX amplifiers, while still using a simpler AB power supply, still offer excellent sound quality for their price.
• • Price: BasX models stay wallet-friendly, so more people can step into great sound. XPA models deliver higher performance and cost a bit more, reflecting the advanced engineering and long-term value you get in return.
• • Flexibility: XPA’s modular design means your system can evolve over time, an option not available with BasX.
