This is the second time I've purchased this exact amp; first for my gym and secondly for my gazebo. The first one is paired with Kicker outdoor speakers and a 12" Polk subwoofer for tremendous sound quality and instrument's distinction. This new amp is paired with the same speakers and a DaytonAudio 10" subwoofer with a unique design for my particular need. The amp powers my systems beautifully with a robust quality that satisfies this audiophile's demands!
I bought this to place in our office with some Klipsch RF-42ii - the sound is great! The DAC is better than what I had, which has brought great life to my music over Bluetooth. The remote is a handy feature for switching between BT and my XBox via Optical. The EQ takes a bit to dial in, but once I got it set up - the setup has been a welcome change in our office workspace.
Good product, good looking
I use this unit with a $2000 DAC through AUX RCA inputs a powered subwoofer and multi thousand dollar speakers
The sound is dynamic and detailed
You have the ability to voice your subjective preferred sound via bass and treble controls with the added bonus of 5 equalizer settings 5 stars
🌟 it has definition and dynamic slam rivals many $1000 offerings
Sound is ok, missing a treble and base refinement, those are little filtered or dial down. Also missing a passive subwoofer output.
