Hi, welcome to the forum Non of the units that you mention have a built in AC3 demodulator for DD unfortunately, even when onboard demodulators were a thing they were usually only available on the higher end of the range AVRs. The only way is to add a standalone model to go between your LD players AC3 RF out & AV amps digital (toslink or coaxial) input.

AC-3 is good for a couple of things. - If you have a ton of AC-3 encoded titles and you enjoy watching them on Laserdiscs. - Seeing the AC-3 signal 'locked' led turn ON is satisfying to some.

However, the next alternative is to find an older AV Receiver that has the AC3-RF in and optical output that you can use in the same way. I know most wouldn’t want to do it this way as having another humongous AV Receiver next to your current one is just a waste of space. It was nice while it lasted It took them a decade or two to catch on though.

While I do like getting all the goodies from laserdisc I'm realistic. I have DVD, Blu Ray, and 4k so it only goes so far as to how much I'll spend on an older media source that has since been surpassed.

You can check out this list here…. https://www.lddb.com/hardware/part/ac3rf/…… and look under “AV Receiver”. You’ll have do a separate search on each model to see which one’s come with an optical and/or coaxial digital output (some don’t come with any digital outputs so you would be stuck using the AV Receiver as is with your speakers plugged into it). For “Processors” that have an optical output, the models to search for are….. Sony, SDP-E800 Sony, SDP-EP9ES Denon, AVD-2000 Keep a search for these on eBay and every so often you might see one listed for a good price.

There wasn't any SDP-E800's for sale. Last one was sold in Sept. I did find this though: https://www.ebay.com/itm/386114965419Says AC-3 right on it so that seems like another avenue I could go.

If you can currently use a 5.1 system (a real 5.1 system, no headphones or soundbars) then 5.1 from LD is just converting one single cable into one other single cable with a small box. If you don’t currently have a 5.1 system then a demod is just a dumb box and you are free. You don’t have to waste time getting on the AC-3 hype train that many of us have already gotten off from when we realized it wasn’t so great.

I suppose though they wouldn't be asking those prices if people weren't likely to pay them. But LaserDisc was ever an expensive hobby. When I think back to the prices I paid back in the 1990s - I had a Sony MDP-850D (£700), had to buy an AC-3 mod for it (about £40 I think), and had a Pioneer SP-D07 with RF input (£400, in a sale!). And one AC-3 disc (Star Trek First Contact, £30). (to convert £ to $, add a bit! Very scientific). In real terms given 30 years of inflation, those prices would be much higher now. But nowadays with some judicious eBay shopping, you might get the same items for £200, £30, £100, £5 (just a random guess!)

And also the people on ebay that want insane prices for older tech that's older than me....rant over. Funny how it seems everyone new to the hobby has these high expectations and no patience when they want something. Key words I tell everyone, "be patient". Based on what I said in my 2nd post, I thought I painted a picture of doing just that but maybe I wasn't clear enough (so my bad). Anyway, let's talk about this again. It can take months or even a year to track down the processors that I have mentioned especially if you want to get it @ a good price. Even in the last year searching on ebay, craigslist and used AV shops, I have seen them come up and disappear just as fast. Depending on the seller, many don't even know the value of the item so there is your chance to get it for a good price. If you go the AV Receiver route, I still see a lot more variety in used AV stores and the prices are very reasonable. Just do your homework, keep your expectations in check, and you never know what you might find.

You don’t have to waste time getting on the AC-3 hype train that many of us have already gotten off from when we realized it wasn’t so great. No need to be condescending. I have no issue with "wasting" my money on obsolete antiques. I "waste" it all the time on cassettes, 8 tracks, CED's, and even VHS. I love vintage media. My point is with all of those other media items I listed I never needed some super specific item to get the best out of them. I have a home theater, that was my whole point about inquiring about getting the best from LD's. I find it neat and pushing the older piece of media to it's limits is very interesting. You must realize that I'm very new to this whole LD thing and I was not aware that the AC3 thing is not worth pursuing.
