Nautilus issued of a number of titles that were half speed masters that were dbx encoded (Allmans at the Fillmore, Moodys Threshold, Clapton One Night, Heart S/T to name a few). You do need to play them with the decoder. You can still find them here on Audiogon and on ebay. Based on the prices they are going for, the non encoded versions are selling for more than the encoded version. Is that because people don't have or don't want to get a decoder or because the encoded versions don't sound as good? I spoke to one guy who deals in high end LPs and has a decoder and he told me he prefers the sound of the non encoded half speed master of the same title.
I have a number of those. Without a decoder, they sound thin and uninteresting.

Dbx ever make a encode~decode unit 4 playing reg lps that could benefit from nr?
I sold audio when these came out. The dbx LP system was a fixed compression/expansion scheme; I think it was 2:1 compression and then 1:2 expansion. At the store (1975) we got a demo LP and hooked it up. Before the music started there was dead silence at the speakers and we thought we had a disconnect. Then the music came out and it was really lifelike and dynamic.

I always did feel like CDs were unnecessary; if the industry had taken the same care to master and press LPs, especially if the standard had moved on to dbx, we would have solved the noise floor/dynamic range problem without going to a completely new playback system. dbx would have simply required an outboard decoder to switch in for dbx LPs.

At that same store, we often used an adjustable dbx Compander set to 1.4:1 expansion to add dynamics to compressed-sounding LPs.
