ENOB stands for Effective Number of Bits and is another measure of a DAC’s performance. No 24 (or 32) bit audio DAC can achieve true 24 bit performance, In fact, 20 ENOB is generally considered the “Holy Grail” of real world DAC performance. The ODAC is just under 19 ENOB and the Benchmark [DAC1], even referenced to its full 7+ volt maximum output, is 19.3 ENOB. The FiiO E10, even in 24 bit mode, is only 16.2 ENOB.
Sampling frequency and bit depth are independent of each other.
At the risk of spinning off a digression: what is the maximum effective number of bits available in a DAC these days -- and does that number depend on the sampling frequency?

Some of the commentary on the internet has been not especially well informed, for example there are some crazy claims at https://news.ycombinator.com/item?id=3668310. If you're in a "someone is wrong on the internet!" correcting mood, you might want to go leave some comments in furtherance of the collective intelligence of mankind.

(Shouldn't be, it is not that demanding?)
Audibility of a CD-Standard A/D/A Loop Inserted into High-Resolution Audio Playback [...]Not one listener throughout the entire test was able to identify which was 16/44.1 and which was high rate, and the 16-bit signal wasn't even dithered!
By the by, I recently added a little writeup about TOS 8 on the wiki. Thought I'd mention it after seeing Monty referencing TOS 8.
