Is less than 24 bits worth it?


I see so many attractive CDP's for sale on this site that have 18 and 20 bit resolution (Naim, Theta, Classe, etc.) Does it make sense to still buy one as a stand alone or should I only consider 24 bit? Thanks for the advice.

Let me disclose that I'm not an engineer. That said,I'd rather have a good,well made 16 than a 24 that has been rushed to market untested.
With all of the above having been said, what are some reccomendations for a used player in the $1k range? I use a Classe CAP-100 and Spica TC-60's and listen to mostly all kinds of music.
hahah.... looks like Ghostrider said it all and Jond and i were typing the same exact things at the same exact time. Look at our opening lines : ) Sean

My first CD player, a Mission unit, had only 14 bit D/As, (oversampled) but was vastly superior to contemporary Sony units which boasted 16 bits, so I agree with sean (for a change). That being said, and all things being equal (which is not always true) 24 bits has potential for sonic improvement if the rest of the circuitry is up to it.
