Laser assembly for YBA CD1a

Seems Indulgent!
A few months ago my Sony SCD-1 stopped reading cd's.
Instead of investing $350 in a 10 year old player,I sold it as a transport.
With those funds I purchased XA5400es and am thrilled-
It's much improved/modern then the SCD-1.
Balance,clarity & groove w/tube like presentation

Wow that's an old one;
How come you don't see(hear)the benifits of a new gereration player?
