Fosi V3 Mono Monoblock Amplifier - Introduction and Demonstration 

Excelente explicación, felicidades y muchas gracias, todo muy bien explicado, reciba un cordial y respetuoso saludo desde México, una ves más muchas gracias

Thanks for sharing OpAmp options list.

I'm new at this. Are the op amps in this unit - one for the RCA inputs and one for the balanced inputs? The Sparkos chips are expensive and I can only buy 2 - and with those two I'd like to replace the RCA inputs' op amp. Is this correct?

Can it drive 2 ohm speakers?

its not worth 200$ update

Why does it need 2 op amps, exactly like the stereo models ? Also, but it is my personal opinion, you don't need so much hands talk, especially when not pointing out anything.
