I have your DAC hooked up to my $16,000 CEC TLO MkII transport.

I use a Optima Red Top 12V car battery as you suggested.

I have a $15,500 Reimyo CDP-777 CD-player too.

The CEC/Altmann is the best CD reproduction, I have ever heard.

Bass is subterenean, and soundstage endless.

The detail is extrodinary, without being harsh or etched.

I am thrilled thank so much.

Merry Christmas.
