🎯 Which Scenario Are You?
Choosing an amplifier feels like a puzzle, but it really comes down to your space and what you’re plugging into it. Before you buy, think about your speakers’ sensitivity, how much room you actually have, and whether you need wireless features.
❓ What is your primary concern?
If you have large speakers in a big room, prioritize wattage. If you’re listening at a desk, focus on low noise and high-fidelity components.
❓ What is your budget level?
Check your source. If you’re streaming from your phone, Bluetooth is a must. If you have a DAC or turntable, look for reliable wired inputs.
❓ How often will you use it?
Think about the future. If you might add a subwoofer, look for pre-outs; if you’re building a rack, look for trigger functionality.
