The lightning to 30 pin adapter is confirmed to have a wolfson dac. It also supports digital out bypassing said dac if the connected device is apple certified. Or you could have DHC mod a regular lightning cable to be as small as you need and skip the bulk of the 30 pin adapter being in the middle.
Thanks and I just learn something new. I did another quick test of the VERZA with my iPhone 4S and found it sounding the same compare to my iPod Touch 5th Gen, so I guess you are right that the adapter is bypassing the Wolfson or else they would have sounded different.
