ACA v1.8 Looking for just a bit more gain

Im using an Echo Dot for source, which isn't putting out anywhere close to 1v output.

I was wondering what it might take to have perhaps an adjustable matching/gain in this ACA if at all possible? I took a look at an early style Soudstream D200, which isn't using OpAmps... but I may be tracking down the wrong path?

Is there a way to add a small gain pot to the ACA by chance?
 
My pleasure.

FWIW... The search function of DIYA doesn't always work as well for me. I knew I had read something like that over the past several months, and Mooly is a trusted source. So I used a popular search engine with the criteria site:diyaudio.com "ACA Gain Mooly" It only took a few secs to spot the one I was looking for.

Believe me, I can't get through all that either. 😀 Hope it works out well.
