Hi Andrew T is this amplifier is not good for bass or low frequency. when i read some viewer
replay i think that is it not HI FI amplifier if that is true i am disappointed

I have not built any of Apex's amplifiers.
But as with all amplifiers, the filters determine the passband.
The ability of the amplifier to pass current from PSU to speaker determines the sound at the speaker.

have you seen the title of this thread? "QUASI Amplifier for Beginners" ,what does it tell you? For hi-fi try nx14,sr50-100-200 or say f100 . I have found a lot in nx14,it is one of my top 3 amplifiers that i have built and heard.
