CD transport parts are going to be very hard to find eventually, but as someone said on another thread, the 3D printing is going to allow many users to repair old devices very cheaply.
I get berated on here about my views on new CD players not sounding better than stuff from the 80s, but guess what, they don't!
I use Meridian CD players from the early 90s. My first CD player was a Marantz CD 6000OSE KI, but I was never satisfied by its sound. I tried a Denon after that but again, I didn't like the sound and it was skipping although it was a cheap second hand purchase.
I then decided to find something better, so I did hours and hours of researching online. I saw a Quad 67 for sale and nearly bought it. These have an extremely good reputation and it's said that this CD player is still one of the best sounding CD players ever built. What put me off, was that they're criticised for being somewhat 'bass light'. Eventually, I decided on a Meridian 206. As with the Quad they have a good reputation and particularly with this model for producing an 'analogue' type sound, and rich bass. A few months later I bought a Meridian 508.20, again a CD player with an extremely good reputation, for being well made and having very good sound quality. I also got the micky taken out of me for not buying new, which is fine as I know it was all meant in good jest, (I think😂)
But here's the thing. Both Meridians were working perfectly, all day everyday even though 30+ years old. I sent one away to be rebuilt for peace of mind and it sounds even better, so I assume there had been some degradation of capacitors or something. The other one's going for the same treatment when the repair shop I use has a slot available. Incidentally it's a Meridian 206 and the guy who works on them is a Meridian specialist and said that although lasers aren't available for these models anymore, they very rarely if ever fail on this model.
The other thing is, I don't want my audio gear to come from the PRC. I don't expect anyone else to feel the way I do, however, when I bought some new B&W speakers, looked at the back and saw the words; "Made in China", my heart sank. I sold them partly because of that and because they were too small, which in my opinion compromises their sound. I tried some KEF LS50 Metas, again made in China and again too small, for me.
I sold both the 707s and the Metas and bought older B&Ws made in Worthing, England. To me that is the home of B&W, not China.
My current speakers are 1988 802 Matrix Series 2, all working parts in perfect condition and early 90s 805 Matrix again working perfectly. Both sets of speakers sound extremely good.
I've removed the Crossovers from the 802s and sent them away to be refurbished. They're going to use Mundorf and Jantzen capacitors, so I'm expecting an improvement in sound quality and peace of mind was part of my motivation for doing this. Additionally, all the grill cloths were knackered, so I've bought made in Britain, professional grade, acoustically transparent grill cloth for all three pieces of cloth, per speaker.
The steel frame type cloth mounts for the main speakers were badly bent and slightly deformed. Not surprising considering their age. The use of a vice and some thumb and finger strength from my bass playing conditioned hands, did the trick.
One of the plastic grill frames from the top Midrange housing has some pieces missing . Luckily I've found two circular discs from the ends of a speaker wire reel, which are made of nice thick strong plastic will be used for the repair. I'm going to cut these into the ring shaped pieces I need to do a fix.
My integrated amplifier is a Marantz less than a year old, made in Japan, which is fine by me since Japan is the home of Marantz.
Incidentally, I still have an ambition to get hold of a Quad 67 because I want to experience the legendary sound that these are said to have and with old CD players, I think it's a reasonable idea to have more than one.
