MEMO: To All Bryston Customers
SUBJECT: Bryston IAD Sound Card TEST

July 2015

Hi James

We tested your new Bryston ‘Integrated Audio Device’ in our BDP-2 digital player against the old card on our ‘Cowboy Junkies Mastering Project.’

The exact same Cowboy Junkies Trinity Sessions file played out via AES/EBU of the original BDP-2 audio card into the BDA-2 D/A Converter with up sampling on. This was then recorded ‘analogue’ at 176.4khz_24bit using the DAD (Digital Audio Denmark) AX24.

We then replaced the old sound card with the Bryston IAD and the exact procedure was repeated. The 2 files are aligned and phased match on parallel tracks and played, switching A & B between the two.

No Contest, empirically proven, Night and Day Difference. As if a wool sweater has been removed!!

The High frequency definition is outstanding, in fact, it is scary how rolled off the old card top end was. Slight improvement in bass transients. Sound stage was much more stable. Less sibilance on voice. Upper midrange was more open. Depth perception much deeper and wider (better resolution of high frequency reverb reflections)

Congrats James
