Here's the link to Audiostream's review of the Overdrive ODSE + Power Supply + Final Drive + Short Block

Reviewer's comments, comparing it to the Bricasti M1 :-
"The Overdrive SE sounded closer to the tonal balance and general sound of the Bricasti Design M1 DAC. The $8995 Bricasti was even faster and more resolving in the midrange and highs than the Overdrive SE and while possessing much of the general ease of the Analog DAC. Adding the Final Drive, Short Block, and direct balanced connection brought the Overdrive SE’s performance closer to that of the Bricasti Design M1."
