The Best Budget Amp So Far? AIYIMA A70 Review Reveals All!

Summary

The Aima A70 amplifier review covers its performance, power output, and features. It delivers around 80 watts per channel at 8 ohms and up to 200 watts at 4 ohms. Despite not meeting the advertised 300 watts, it offers solid performance, with good build quality and protection circuitry. ABX testing showed no significant difference in sound quality compared to higher-end amplifiers when power output was matched. It's suitable for medium to small rooms with sensitive speakers but may lack power for larger spaces or less sensitive speakers. The review also discusses its inputs, subwoofer pre-out, and power supply options, concluding it's a reliable choice for its price.

How does the Aima A70 amplifier perform under stress?

The Aima A70 is described as a solid amplifier that can withstand a good amount of abuse, remaining powered on for days without overheating or experiencing power failures.

What is the approximate power output of the Aima A70 amplifier at 8 ohms?

The Aima A70 provides about 80 watts per channel into 8 ohms.

How much power does the Aima A70 amplifier deliver at 4 ohms?

At 4 ohms, the Aima A70 delivers closer to 200 watts, depending on the power supply used.

What was the outcome of the ABX testing comparing the Aima A70 to a 200-watt monoblock amplifier?

In the ABX testing, the only noticeable difference was the higher power output of the monoblock amplifiers, which allowed for louder volumes without a significant difference in tonality or other audio qualities.

What are the input options available on the Aima A70 amplifier?

The Aima A70 amplifier features both RCA and XLR inputs, with indicators that light up when engaged.

Does the Aima A70 amplifier have a subwoofer output?

Yes, the Aima A70 has a subwoofer pre-out and a 12-volt trigger, but it lacks a high pass filter for the main speakers when the subwoofer output is engaged.

What power supply options are available for the Aima A70 amplifier?

The Aima A70 comes with a 48-volt 5-amp power supply, or for an additional cost, a 10-amp power supply can be purchased.

What is the distortion level of the Aima A70 amplifier at various power outputs?

At 8 ohms, the distortion starts to ramp up significantly at about 114 watts, and at 4 ohms, it's about 144 watts before protection kicks in.

How does the Aima A70 amplifier's frequency response vary with different loads?

The Aima A70 shows very little variability in frequency response between static loads of 4 ohms and 8 ohms. However, with complex and simple loads, there is some variability, with the complex load showing slightly more significant changes.

What is the reviewer's overall opinion of the Aima A70 amplifier?

The reviewer gives a positive review, stating that for $200, the Aima A70 is a good product that performs well and is recommended for medium to small-sized rooms with reasonably efficient speakers.
