I tried firmware 1.11 with a 32 GB SanDisk card filled with 1999 MP3s. The lag after pressing the menu button from the «now playing» screen amounts to acceptable 2 s when playing and 1 s when paused. After reinsertion of the almost fully loaded Samsung 128 GB card I'm back to 5 s when playing and 3 s when paused. This compared to 0.1 s with firmware 1.1.
I just figured out that pressing the menu button for ½ to 1 s immediately brings me to the main menu. So all is good.
I'll try replacing my coax cable with something a little more high end. Since I'm switching from Toslink, I just bought an inexpensive--but typically quite good--Mediabridge cable until I could figure out what cable to buy for the X3. But right now, it seems the fault lies with the X3 2nd Gen: the digital out works now with this beta firmware update, but the quality just isn't there--it sounds tinny and thin, and the stream also seems to be some missing data in the 14-18 kHz range (something just doesn't sound right in that range since some details are just gone). Also, a 6 DB increase in the EQ's bass does not appear to produce a 6 DB increase. (I'm trying to use the X3 to drive a Schiit Gungnir DAC and Woo Audio WA2--replacing the iPad/Jive Cable/Pure i20 combo I've been using (which produces excellent sound, but which has other limitations). Here's hoping the cable's at fault.
I can't reproduce your experience. Firstly, with my player the digital out worked from the start; and secondly, the latest firmware (after 1.1 – sans beta) is 1.11 beta. The digital signal I get is flawless and now (since 1.11) even incorporates the EQ function. Speaking of the latter, the 31 Hz slider does its work. Maybe there's not much sub-bass in the music sample you used for testing (?). «Missing data in the 14-18 kHz range» doesn't make sense; it's simply impossible for a cable or DAC to eliminate frequency-specific data.
