And HiFiMAN HM-901? http://www.stereophile.com/content/hifimans-hm-901-portable-player-and-re-400-ear-monitor $999
Although a portable media player, it incorporates 2 (TWO) ESS 9018!
That's a bit crazy to me, no other product need 2 9018 chips.
The comments from the CEO of HiFiMAN of why using 2x 9018 (http://erji.net/read.php?tid=1300699):
"by using 1x 9018 and tweaking 5 different Low Pass Filter designs, we achieved the sound similar to Meridian 588"
"but comparing to our reference equipment combo: Accuphase DP100 + Pacific Microsonics Dac, we are not satisfied by 1x 9018."
"In the end they used 2x 9018 for each channel, and using 2x OPA2107 and 2x OPA627 as low pass filter."

Other DACs using the ESS ES9018 are $699 (Yulong D18), $1500 (Anedio D2), $3999 (Resonessence Invicta), $899 (M DAC), $1999 (Benchmark DAC-2), $1100 (Minimax Plus), etc. On the higher side they can be many thousands of dollars (see Weiss, Invicta, Calyx Femto) and on the low side only a few come in under $1K. The average is probably $1500 or $2K if we add them all up (which I'm too lazy to do).
And personally I hardly ever use optical. Nearly all my DACs have it and I really don't need it. I would think most people are in the same boat as me, but then again there's always an exception.
