the o/p of your chinese amp may be low. or it may not be hi fi

A guitar amplifier usually produces not much bass sounds and not much high frequency sounds, something like a telephone. Maybe that is what you like?

Describe what you call "poor". Maybe your stereo amplifier does not produce as much power as your guitar amplifier?

high distortion

You must fix your amplifier or buy a new one.
My stereo amplifier produces 70W RMS into 8 ohms or 120W into 4 ohms per channel at 0.05% distortion. I use two speakers in parallel (front and back) for each channel. The distortion is so low that it cannot be heard. About 30 years ago I had surround sound but not now.
I never operate the amplifier at full blast so it never clips.
My amplifier was not designed and not made in China.
