Everything I’ve read indicates a 3 dB reduction at 20 kHz for NOS DACs due to the “sin(x)/x rolloff” phenomenon. I wonder why/how the Valab is different in that regard. Did you happen to measure freq response before any mods? |

Understand this is one of my most difficult recording for me to enjoy with digital audio, a real litmus test. Well.... while it sounded good I have to admit I wouldn't want to listen to the whole piece. Mind you my Mod Dac churns through this piece all while toasting and buttering your bagel. |

Removing the 8 screws on the front/back, the 3 screws holding down the Dac board & soldering in the new BG took me all of 10 minutes. |
