Rather good, especially as you can get them for little money (less than £50).

re: Sonamp 260

Just bought one of these. I could use some help. If I apply a signal and turn the volume up just a bit, the protection circuit kicks in. I thought it was my preamp so I bypassed it. The problem persists. Is there some way to adjust sensitivity on the protection circuit? Any components I should swap out? I can't find a schematic for this amp. Any help would be greatly appreciated.

re: Sonamp 260

There is two opamps right behind inputs, One or both said bye bye. It`s cheap to replace and no soldering required.

re: Sonamp 260

These amps almost never break. Check your speakers and speaker wires for shorts. While they will work well with 4 ohm loads ( 2 pairs of 8 ohm speakers ) they are designed to open the protection relay with
speaker loads below 2 ohms. The other possible issue is one of the small caps in the protection network.
If open bass notes will trip relay. I have sold and installed many 260 and 260 x 3 and still own a few of them for my own house audio system. I never seen a schematic , but they are a very standard circuit. Good luck.

I got two of these amps for $30 and I am blown away by its performance.... I had no idea they sounded this good and they brought life back to my speakers..... you can run Tower speakers with no problem.
