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!!

Great produkt, great service

Stand Its stále and good working.Fas shopping.

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.
