Well it depends how much power your version of the AlephX has. I think the original schematic delivered 30 W, so with inefficient speakers it is maybe a bit low when you want to play really loud.

However I think 8 V are far too much input and drives the poweramp only into clipping since its rails are 15 V!

Cheers, Hannes

Have you grounded the unused input? If you're using a single-ended input, that's good for 6dB right there.

Hi,

the gain is 20dB so 1 volt input will give 10volts output.
For a 100 watt/8 ohm Aleph x this means around 2,8volts before clipping.
