Is it a good idea to buy CD players over 10 years old even it is a reliable brand?

REGA ISIS or ISIS VALVE cdp/ DAC 

Each unit produced had its tech test and archive not one, but two spare laser units. I think it’s safe to say that the ISIS will last longer than most of its owners and one can appreciate appreciate this attention to detail, with CD transport mechanisms getting scarcer all the time.

For 3K you can get a very nice brand new or gently used CD player, whose sound will be very competitive and which will be guaranteed to keep playing a good deal longer.

I would make sure that replacement lasers and transports are available. I bought a used Esoteric player last summer and it would not play hybrid sacd’s. Fortunately, I also bought a Square Trade policy. They paid for a new laser mechanism and the labor to install it. I would recommend that you get a Square Trade policy or something similar, if possible.

You should also be aware that some Esoteric models need to be shipped to Japan for repairs. I don’t know what the deal is with Accuphase. If you are still considering the X-05, I would call TAP Electronics to see if they can do repairs to that particular model at their California location instead of shipping it to Japan.

No,  It's time to move to the 2020s.  Buy a DAC and rip your disks.  Better SQ.  Don't let mechanical disk playing get in the way of your music.

@melm ........................why is it many like you constantly diss a CD player and push streaming on people when they specifically ask for CD player opinions?  If these people are in these forums, then they know about streaming.  

I have both a music server and Esoteric SACD player and I much prefer playing the little disks even though the music is ripped to the server.  If I use the server, I never fully listen to whatever is chosen in its entirety, with the CD I do.  

Try to answer the question the OP asked please.
