Hi Charles,

Got my optima battery Sunday.

I am very pleased with it.

It is a significant upgrade on both my heavily modded Marantz player (new clock, black gate caps etc) and the DAC-AH Lite NOS dac.

Its everything I hoped for and more.

Better in every respect.

I am seriously hearing things that werent on the CD before.

Thanks very much. Stunning product.

regards

Dave
