Hi Charles,

For almost one year I have been really enjoying your amplifier and DAC:

Honesty and clarity are the words that come to my mind when I think of their sound.

But there was a new surprise for me: two weeks ago, I found an Optima battery; I had been using another brand.

With the Optima, the sound is more precise, even cleaner.

So, thanks a lot.

Alejandro
