cd/dvd repair ot trash

I am the unfortunate audiophile who keeps experiencing equipment failures.Specifically;A Meridian 800 with HDMI output,cannot read the cd /dvd ,although the unit was repaired by the factory for that precise problem under warranty in the last few month.Yesterday my Esoteric DV-60 failed to read the cds.I purchased that unit new from an authorized dealer,but that was a few years ago. My question is it worth the cost and trouble repairing
