Power supply improvement for CD player

If the power supply components are replaced with those as
outlined, and of the same values as the OEMs; the only
characteristics that will change will be a quieter/blacker
background, greater dynamics, more natural highs and
improved sound staging/imaging. I've done these mods, or
similar, to a wide variety of components, over the past 35
years. The reactions/appreciation, from my customers, were
unanimous and always enthusiastic. Virtually every piece of
equipment I've personally owned, has also undergone power
supply mods, with nothing but a more realistic presentation
as a result. I listen to way too much live music, every
week, to accept otherwise. I don't hand out advice lightly.

Why do you want to change the PS ?

Jafant. It's not that I 'want' to change the power supply-- I'm just searching for ways to "improve" the detail, nuance' perhaps lower the sound floor, provide a little more dynamics. I appreciate finding economical ways of improving sound.

Rodman your info is much appreciated. (Expertise is not obtained without time and effort and usually cost. Sounds reasonable to me. I am not technically knowledgeable and would be afraid to try doing any work myself. What level of technician is required for these changes? Where are you located?

I hear YOU RODMAN99999. These things (improvements)are possible by that route. No doubt there. I'm only advising the practical. Our fellow(or other)member should take a serious look... at what's ALREADY ON the PS board, and do a small(uhm) evaluation whether it's worth it/practical to swap-out any component after it is compared to a possible replacement. I would bet Lexicon did well on PS execution(device selection) as is. BE AWARE OF THE SITUATION. Then act accordingly to your findings(re:"across the board-out-of hand", no..no.). Recommended every-time. Personally, I've tinkered since High School. In '78, I attended the Army Signal school at Fort Gordon,GA in the Fixed Radio Repair (32H)course. Served as a technician with the 323rd Maintenance Co. at Ft Devens MA for some time. I play guitar, my baby is a black '67 Les Paul Custom I (I purchased in '79 for $500. try that today..).That said, I always search for ways to get better audio quality from stuff I own, as I'm sure we AudiogoN's do as a community. I will only try to give bottom line advice, not experiments or assumptions about what's in what YOU own, unless I OWN, or have in the past have had direct knowledge of THAT unit's design. Circuit modifications on well designed(RT-20)digital gear, that cannot be measured(lucky for you), are subjective and subtle at best. Or it wouldn't have been what you wanted to own in the first place, right? Better Fuse($$),ok...,esoteric power"cord", well...cable gauge(thickness) maters most, before alloy quality($$$) or any theoretical strand layout schemes($$$$). You can find a "ultimate" power cord at HOME DEPOT.Throw away that "detachable" socket and solder direct to unit. Use a decent Hospital Grade plug for the wall side from there as well, with $3.50 snap-on ferrite blockers attached to both ends from PARTS EXPRESS, and forget about it. I feel I have expressed quite enough for today, hope you manage to enjoy the music!
