Hey Lowrider,
How you do'in with you PWT? Hope things are running very well for you. I had a devil of a time incorpoating the PWD into my system. What started out as "a little weak on the bottom and somewhat shrill in the upper ranges" turned into,"weak on the bottom and distorted on top". Took me all this time to get it back to satifactory sounding.
Nowadays, CD production tends to push the strength and volume of vocals very hard, a little into the "red" zone. Especially, when three or more voices are singing a chorus. Pushing a chorus of vocalists into the red zone will add a little extra buzz and excitement to the song - sounding like a larger, more robust chorus.
Unfortunately, my PWD was interpreting the little bit of buzz/distortion as an additional voice. So instead of getting John, Paul, & George plus a little buzz on top, what I got was John, Paul, George, and Ringo, on a day when Ringo had a terrible cold - but still insisted on singing. I had an addition vocalist that crackled on the recordings that I could point to. "There he is".
This was especially noticeable on groups with male singers and notably on remastered recordings. I love the midranges of mastered recordings but not distortion. I actually stopped listening to music unless I had a new piece of equipment to try out to see if it could help tame the beast.
Power cords, interconects, speaker wires, speaker replacement, different EQ curves, etc, etc, were all incorporated. It all helped a little and then I got in some upgraded fuses this week. Along with the rest of the new equipment, the fuses finally put the sound back on the right track. It's still not perfect, but it's close enough that yesterday, I was able to enjoy listening again. I put two Padis fuses in the PWD and one SR black fuse in the PWT. The Padis fuses help remove a little of the distortion without taking away the midrange or the treble. The black fuse really helped with the distortion, but SR fuses tend to throw a veil over the midrange and treble and this fuse is no exeption. I can learn to live with it though. It's awfully close to being where I want it to be.
Did you get your difficulties figured out? I see you're looking for a NOS DAC.
Have a good one.
Tim
