Quoted from ScottThePhotog:

Laserdisc collector here. I grew up watching Tom and Jerry and the Looney Tunes on Laserdisc. Still have those box sets and will never get rid of them.
I started seriously collecting about 3.5 years ago. I've got over 1500 titles in my collection. For me, nothing beats Laserdisc when it comes to audio. Uncompressed digital audio, original theater mixes, and killer AC3 and DTS soundtracks that will shake the house!
One of my collection goals is to be Criterion Collection complete, and I'm about 70% there. There are so many releases with great extras and commentaries that aren't available anywhere else.
One of my favorite things is to spin a late release or DTS disc for someone who has never seen a Laserdisc. They are always blown away by the sound and typically impressed with the picture quality, especially for a technology designed in the 70s! Hearing the blu-ray after is always a let down.
The picture quality on late releases is usually quite good. Sometimes on par with DVD or better since there is no digital compression or artifacts. It's amazing how much they were able to progress and maximize the potential of that format. The difference between the very early DiscoVision titles and the releases in the 90s with discrete surround sound is just incredible.
This was my collection about a year ago. I've added probably about another 100-200 discs since then.

Quoted from Rdoyle1978:

There is - look up a component called a “line doubler”. There are also little boxes which take a component connection in and convert to HDMI. Quality varies wildly though

Quoted from timtim:
