My pleasure, Joe.

There's a white paper out there somewhere talking about OPPO's use of the supposedly superior SABRE 32-bit DACs for the volume attenuation. On paper, it seems the 32-bit DAC's will provide zero loss of signal unlike other digital and analog volume controlling methodologies.

In my case it was quite a significant gain for several reasons.

1. The enhanced detail of every last instrument, more pristine, delicate, extended, etc. I suspect due to a lowered noise floor and perhaps zero or near zero signal loss.

2. I love dynamics and take great pride in my systems dynamics that I've yet to hear elsewhere. I swore many times I'd never go the passive route for that reason alone. However, upon recently purchasing some 575 wpc mono amps, with an active preamp and amplified gain, the dynamics, especially most any note's initial attack was so in-my-face, that there simply was nothing realistic about it. Frankly, I was experiencing a severe case of electronics-induced jump factor where my ear was maybe 2 feet from the note's initial attack but then my ear was maybe in the first row for the remainder of the note.

Some obviously are impressed with these electronics -induced jump factors but there simply is nothing realistic about them. Not even if you're going back to a 1978 Ted Nugent concert and you're sitting in the front row.

The combination of the OPPO's fabulous passive volume attenuator and the very dynamic 575 wpc amps turned out to be an excellent combination putting all the music back up on the soundstage where it belonged and my ears back in row 5 or 10 where they belonged. And I still have perhaps the most dynamic system I've yet heard, only now it's a more natural and slightly more rounded dynamics from a distance in the audience.
