    Internal load resistors do NOT switch into unused amplifier as advertised. Tech support were no help and would not admit that design is flawed.

    5.0 out of 5 stars If you have multiples of amps and speakers, you need at least one!
    Reviewed in the United States on April 28, 2025

    If you are one of those weird audiophile types that has multiples of EVERYTHING, you need at least one of these. I am one of those weirdos. I have 4 variations of this and this one is my favorite. I am always comparing different amps and speakers. This lets you do it via remote control and stay seated in your listening position. If works well, its easy to use and setup, and looks good. At the price, it is a good value. It is a little bigger than some of the others, but I like the look so that was a plus for me.

    Reviewed in the United Kingdom on December 31, 2024
    Verified Purchase
    This is not particularly cheap, but is easy to install and works well. It looks smart when in use. Perhaps the only downside is that I chose the dark coloured meter option. The unit has ver fine needles on the meters and they can be diifficult to see, but this is a mall issue. The light coloured meters might be easier to see. However, it's a worthwhile addition to a hi-fir separates system.
