I set it up with a Hafler 915 preamp until the pas2 arrives. My source was an oppo 981 dvd/cd player using the internal dac. Speakers were my KG4s. First impression was that while warm, the bass seems muddy. That said any horns, strings, piano, and vocals were terrific. I also have a pair of Vandersteen 1c's to try. Did not spend much time on speaker placement etc.. I know the "sound" is there to find but am concerned about the bass issue. Wondering if the mods made to amp are an issue? PAS2 is due to arrive tomorrow. We will see what difference that will make.Will post the PAS2 build in another topic. Thanks for any input
