  • Good sound and good design

    Involvement Level: Expert (understands the inner workings)

    Pros: Good sound, simple neat design, solid case, separate power supply - you can use your own, good power source is very important for D-class amplifiers (as for any amp)

    Cons: No real cons, but the price is rather high. Due to separate power supply the whole system looks not so neat, and stock PS is not so good I think, it's usual switching construction. But never mind, it just works.

    Other: Real thing. Buy it if the price is OK for you.
