    "Qables iQube v1"
    Pros - Excellent sound, great build quality, excellent battery life, simple to use, nice design
    Cons - Difficult to open and change batteries, surface of plates gets scratches, paint does come off after some use
    I have had my iQube for more than two years now and I love it more and more. I like the sound quality and compared to many other high end portable amplifiers this is one of the top competitors. The level of details is perfect. This is a truly transperrant and neutral amplifier with absolutely no grain or added texture to the sound. It might be a bit more expensive than other portable amplifiers but for me it has been fully worth it. 
     
    The iQube is based in a Class-D topology which is why it is very efficient and runs many hours (50+) on 4 normal AAA batteries.
