Does anybody have any experience with cryo-treating Sony SACD/CD players, especially the XA5400ES model? Or, for that matter, any CD/SACD players?
I ask because I had my Sony XA5400ES laser take a total crap on me (it's old; lots of play time; to be expected), so I ordered a genuine Sony replacement laser for $61 including shipping (from Liberty Electronics of Atlanta), and had it shipped to a friend in the Bay area, who will forward it on to me here in New Zealand.
As it just so happens, this friend is having a bunch of stuff deep-cryo treated (more than -300 degrees F, as I understand it), and he offered me the opportunity to toss the laser in for free.
Free cryo, what's not to like?
Well, a dead laser would be one thing, of course.
Thus, this query.
My guess is that it is absolutely no problem, as I suspect LOTS of people do it all the time (like at Reference Audio Mods, for one.) But with a plastic laser lens and with various unknown parts inside the Sony laser, I figured I should probably ask around and see if anyone has had any problems with CD/SACD lasers after cryo treatment?
TIA for any help or guidance!
Cheers,

WS-
will the parts in question tolerate the difference in temperatures?

I considered doing the same thing a couple of years ago and this was the advice of Charles from Cryogenics International:
"We have learned not to process cd or dvd transports. This is because the laser diode is usually just glued into place. The glue can fail. We also do not process speakers. Other than that, we process most everything"
Charles reiterates my statement about the adhesive(s). And Charles knows his stuff.
I would have at it with all the electronics within, but avoid treating the laser assembly. Certain adhesives will not tolerate the deep temperatures, so if the laser assembly is affixed with an adhesive (especially the lens), that could be quite problematic.
Then again, if anyone on the forum has successfully cryo-treated such a laser assembly, I will defer to their experience.
..... I only have the replacement Sony laser lens possibly being cryo'ed. Of course, I'd LOVE a free cryo of my entire Sony player, but that's over here, down under, in New Zealand. The new Sony replacement laser assembly is in the Bay Area, as is the cryo center, as far as I understand it.
Yeah, I'm hoping someone has done some deep cryo on a Sony laser, or any recent SACD/CD player, and will chime in with how it turned out, both as to the laser surviving the process, and how they liked the sound post-cryo.
Thanks, Alan, for the post. I think what you said is a wise default position (or I should be prepared to potentially piss away another $60 on a new Sony laser, yet again.)
Well, if you want to roll the dice, it's only $60 (as long as you have another laser assembly available). If it comes out intact and working properly, you're ahead. Ordinarily I feel that cryo-treating the electronics would be a much bigger jump, but you don't have that opportunity.
