The amount of clean power that this puts out for its size is truly amazing

Cons: It has a very annoying blue power light -

The oversize power brick may be a problem for some people, but not a concern for me, since it shrinks the footprint of the amp as it sits on my desk

so I wanted to get a decent, clear amplifier to power my JBL Studio 130 speakers in a 4x4m room

Pros: Great sound and power from a tiny amp

This amp has enough power for them,

Works very well, provides clean power to my Micca mb42x speakers

The blue power LED is extremely bright and annoying

It does an excellent job powering the devices and has exellent bass response

Compact, enough power, sounds just fine.
