This is a review and detailed measurements of the Peachtree amp500 stereo amplifier. It is on kind loan from a member and costs US $1,499.
The amp500 comes in the same packaging of many previous Peachtree products. I wish company would innovate here as the design looks kind of dated. Then again it is very unique. This amplifier comes with balanced inputs which I very much like:
When I pushed the amp, the protection circuit naturally kicked it but unlike many other amps, recovered automatically without the need for a power cycle.
The back half of the box is empty so the amp module is small. And there is plenty of ventilation on top. There was only modest temperature rise in the case post all the testing I did which is admirable.
Peachtree amp500 Measurements
The amplifier was ready on power up:
Dashboard measurement shows above average performance:
Noise+distortion as embodied in SINAD is well above median although well sort of state of the art:
I could not come close to matching company spec for SNR:
Frequency response was flat enough and not dependent on impedance which is very good for a class D amp:
Crosstalk was state of the art so I am assuming some kind of dual mono configuration:
Multitone was respectable:
Let's see how power it pumps into a 500 watt load:
That is a lot of power! The clipping is quite sharp though which when combined with the protection circuit, would not allow me to measure max power. But I did get peak power:
I think spec is 700 watts but we are close enough. Even at 8 ohm we have good bit of power:
High frequencies bother the amp but go lower and linearity is excellent:
Finally, we have a new test: power on noise:
I haven't run this test on other amps to know if this is good or bad. Once I do get some mileage on it, we will better know what is going on. If I were to guess, I would say this is good performance.
Conclusions
Story here is simple: tons and tons of power with above average noise and distortion. A cool running switching amplifier in small package as well. Really, nothing much to complain about here.
I am going to recommend the Peachtree amp500.
