new here!! (6-20-11)
i've a copy of the legendary PD-91, a low-hours/ excellent condition example
that i paid a premium for on AUDIOGON;
first things first;
i first came across non-functional copy of this player back around 2007ish
for about $25.00.
i learned how to fix it; the notorious lens falling off of late-'80s PIONEER make
laser pick-ups, which is a common issue with many late 1980's PIONEER CDPs.
the PD-91 is particularly notorious for being intolerant of CD-Rs.
intolerant of CD-Rs, that is, BEFORE one opens up the player,
and turns up the FOCUS GAIN and TRACKING GAIN variable pots on the main PCB
behind the disc transport assembly.
i was able to render that FIRST PD-91 of mine CD-R friendly in that manner.
a couple of years later, i was able to get a hold of a DEAD, but cosmetically perfect
PD-3000, which is the japanese market version of the PD-91.
the 3000 has both the solid aluminum top panel, and the twin DIGITAL/ANALOG
power trafos that was left out of the U.S. PD-91 variant, and included only on
the 1990 model PD-93, which was the direct U.S. successor to the -91.
i took my japanese PD-3000 to a service shop, and was told it was irreparable,
the ANALOG OUTPUT stage was somehow fried.
i took the good cosmetics off the 3000 hulk, and applied them to my functional PD-91.
i heard of some mod work on PD-91 players, and half-cocked, attempted
some mods of my own.
indeed, i attempted to graft the rear-panel/twin trafos to my good PD-91 chassis.
the results? DISASTROUS.
yesseree-bub, i fried my PD-91, and was out a CDP.
i had to go back to the inferior sound quality of my VERY FIRST high-end CDP,
my 1985/1987 DENON DCD-1500 (NOT the 1987/1988 -1500II successor)
for over a year, continuously kicking my own stupid ass all the while.
i mean, the DENON was/is a FINE vintage CDP, with a warm, beautiful sound character,
but i'll be damned if it wasn't/isn't ROUNDLY eclipsed by PIONEER's meisterwork.
thankfully, i came across a cherry of a near-pristine PD-91,
and gladly paid the somewhat-outrageous $610.00, ship. included, on an AUDIOGON listing.
i received the beauty, -with the lens popped off, of course- located it in the chassis,
LIGHTLY super-glued the lens back in it's mounting, slapped those PD-3000 cosmetics on,
and sat back to that oh-so glorious sound, and feasted upon those gorgeous looks once again.
today, about a year after purchase, my baby flawlessly spins any 8x REC.ed CD-R
i load it, as well as any factory disc, with remarkable Aplomb and effortless authority.
i'm in Audiophile Heaven...
