Absolute top tier DAC for standard res Redbook CD

The problem with attenuator volume controls is that they add resistance to the signal path, which adds thermal noise. In the case of passive attenuators, these change the impedance of the signal path, which can cause low-pass filtering and/or loss of dynamics.

The Overdrive DAC has less than 50 ohms in the signal path. The volume technology on it is superior to any other technology available. I can say this with confidence because it adds nothing and changes nothing in the signal path. It only adjusts the D/A reference voltage, which scales the height of the stair-steps created by the D/A conversion. This is the perfect way to adjust volume. No loss in resolution, no added distortion or noise. The behavior actually reduces THD as the volume is decreased. All other volume technologies increase THD as the volume is decreased.

Congrats are in full order Melbguy1 on your Vitus singnature series SCD-025 you will be getting, I would like for you to do a review of the player on the Tara Labs Thread when you get your final impressions of the player after burn-in, cheers Melbguy1.

Steve Nugent, wow!, your volume control is quite impressive too!, see, this is what I'm talking about, closeing the gap with the volume controls today made on modern state of the art dacs and cd-players versus active pre-amps is a big learning exsperience for me here, I had no idea that volume controls these days were this profound!, cheers to you steve.

Thank you steve, could you please give more detail about the OV digital filter selections, and preemphasis settings.

BTW... I enjoy learning about OV from Steve... DSD-S from Alex... And K-01 from Esoteric... Please do continue to sing the refined virtues of your very own designs!

Yet, Call me oldfashioned, I am deeply uncomfortable reading engineers publicly and shamelessly peeking into each other's technical "private parts".
