Powerful little thing

Really woke up my Sony bookshelf speakers. Bass and treble adjustments are wildly impressive. Knobs and switch feel sturdy and smooth. Great little amp!!

Excellent value

I purchased the Merak CD player with the IM4 in ear monitors and it's been a blast using both. The Merak CD player sounds much better than I anticipated and I've rekindled my love for my CD collection. The IM4's punch above their weight and are among the best sounding in ears I've ever tried. Both shipped quickly and were well packaged. I can't say enough good things about my experience dipping into the world of Fosi Audio products.

Second One

Exactly what I wanted for my fiberoptic Blu Ray player. I'm using it to listen to Blu Ray music. My.other one is being used to listen to DSD audio in another room

Nice toy

The player works as expected. Connected to various AirPods and speakers without issue. The design looks cool but limits where you can use it. I would be hesitant to use it outside. Bottom line: it sounds great.

Vermutlich ist hier der Käuferschutz bzw. Transportschutz gemeint.
