I was impressed seeing the small signal performance of this amplifier. Noise is low. So is distortion.
This is a unique chip amp design. Regulated single rail power supply and capacitor output coupling.
I built a Pass design like a this and it played music fine. Not sure how well it measured, the GT102 measures well.
Like has been said, this amp is power supply limited. But really, 60 watts is plenty for most applications. Parallel connecting two channels would be beneficial if driving speakers that have an impedance under 4 ohms.

What I was saying earlier is that you can turn it into a mono amplifier by paralleling both channels, but that will only get you a single 60W into 8R, 120W into 4R.
As I have declared previously, I have no hard science background like the rest here. I have read a lot of the threads, not just about GT102, but regarding Purifi and Modulus, all those 100+ pages threads, just trying to understand and take away some meaningful piece of information - which has been difficult. This is the first time someone has written a post that was helpful for layman like myself, so thank you very much for this. Really appreciated!

I will take your advice and keep the amp the way it is. I think this amp will be great for my beloved Energy Connoisseur C5s.

As Panelhead said, it's a good amp and 60W is plenty in a domestic setting, especially with fairly efficient speakers as yours. You can reach deafening levels for sure.

Enjoy the amp, it's really not a bad one as is.

Can this chassis be made to turn into a dual monoblock, for example?

Thank you, any sort of advice would be wonderful.
buy & build the Neurochrome lm3886 amp.. If you demand better
