Some years ago I bought the first version of the DX3 pro. Over the past few months I starting using this together with a Samsung TV to send the optical output to powered Yamaha speakers. And that seems to have worked very well with terrific sound quality, no glitches and no momentary interruptions to sound.
Most recently I needed an additional dac and decided to buy the very latest topping DX3 Pro+. Out of curiosity I tried this latest DX3 Pro+ with the tv and speakers. Sound quality was still terrific (and to my ear, identical) but there are occasional momentary dropouts in sound (only apparent with music).
I recall that jitter from the tv optical output might the underlying reason, and occurs when the DX3 Pro+ thinks there is sync error with the tv and recalibrates .
With the v1 DX3 Pro this doesn't seem to happen. I think the V1 uses an AKM chip while the Pro+ uses an ESS chip.
I'd really be interested to find out in more detail about this difference and why this is so.
