I fooled around with dbx encoded discs about 12 years ago - in fact I still have a bunch of them. I ran them through a dbx 224x encoder/decoder (which I still have as well).
Compared to unencoded discs, the dbx discs had enormous dynamic range and were very quiet. There was almost no trace of surface noise, and cliks and pops were much reduced in level. Since dbx is a constant slope system (unlike the various Dolby NR systems which perform noise reduction relative to a special referenxce level), one could dub a great dbx encoded cassette by merely feeding the undecoded dbx signal from the disc to the tape deck (with its internal noise reduction switched off, of course).
Though impressive sounding at first, the dbx encoded discs seemed veiled and lacking in transparency after extended listening. I found that I preferred regular unencoded vinyl.
I also feel that Dolby C and S are both better sounding than dbx. However, dbx has one advantage - its 2:1 compression ratio allows you to record more dynamic range than Dolby, thus it may be a better choice for live recording.
BTW, the cassette deck used was a Nakamichi Dragon.
