  • Excellent Amplifier

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:

    Very nice look, good combination of aluminum black case, front and back plate are silver. Sound quality is also excellent mainly from CD and DVD player, but from USB MP3 files have small noise between tracks.

    For better performance from CD or DVD via RCA plugs I suggest changing the resistors on input path for both left and right channel. For signals put 1kOhm resistors other two between signal and ground put 220kOhm. Volume quantity become much more.

    Cons:

    Bottom 3 red LEDs are too bright so if you can put diffused yellow and one red type.

    No user manual.

    OtherThoughts:

    Remote control is only for MP3 files through USB or MMC card. Volume control put near maximum so you can regulate on remote control toward minumum.

    Bottomline:

    I use it with two-way speaker system about 60W and 8 ohms impedance. For power supply 12V 2A is suitable.
