Quick answer
Choose an Aperion Energy power amplifier based on your speaker setup and listening habits: the E2 for pure stereo, the E2H for high-power stereo, the E7 for a full 7-channel home theater, or the E3H for a 3-channel front stage. Each offers a separate preamp/power amp path for cleaner sound than a typical AV receiver.
Why separate the preamp and power amplifier?
A separate preamp and power amplifier reduce electrical interference inside the chassis compared to an all-in-one AV receiver. This can give you cleaner headroom at high volumes and less crosstalk between channels. The trade-off is more boxes and cables, plus the cost of two components instead of one.
Channel count vs. future expansion
If you already own a 5.1 or 7.1 preamp/processor, a 7-channel amp like the Energy E7 powers every speaker in one box. For a 2-channel music system, the Energy E2 or E2H keeps things simpler. The E3H sits in between: it drives left, center, and right channels for a high-performance front stage, leaving surround channels to a receiver or a second amp.
How to choose your Energy amplifier
- Start with your speaker count: Count the speakers you plan to power with the amplifier. A 2-channel amp (E2 or E2H) drives a stereo pair. A 3-channel amp (E3H) drives left, center, and right. A 7-channel amp (E7) drives all seven speakers in a 7.1 layout.
- Match power to speaker sensitivity: If your speakers have a sensitivity below 88 dB or you listen at reference levels in a large room, choose a higher-wattage model like the E2H (1000W per channel into 4 ohms) or the E2 (330W into 4 ohms). For efficient speakers in a small to medium room, the E7’s lower per-channel power is usually sufficient. Check your speaker’s nominal impedance and sensitivity spec before picking a power rating.
- Decide on future expandability: The E7 leaves no room to add more powered channels later unless you buy a second amp. The E2 or E2H can be paired with a separate multichannel amp later if you add surround speakers. The E3H can serve as a dedicated front-stage amp while a receiver handles surrounds.

Which amplifier fits you?
Best for
- Stereo listeners who want pure two-channel performance: Energy E2 or E2H
- Home theater owners with a 7.1 preamp who want one-box simplicity: Energy E7
- High-power front stage in a 5.1.2 or 7.1.4 system: Energy E3H
Not ideal for
- Budget-constrained buyers who need an all-in-one receiver (these are separate power amps, not receivers)
- Systems with more than seven speakers unless you add a second amplifier
