wadia and msb are both very good about customer support. I have owned gear from both and have sent gear to be upgraded. msb ilink deals with the jitter of the digtial that will be comming out of the ipod. How, they use a dsp and high recision oscillators to re-clock the spdif output of the ipod. I have emailed wadia to see what they do if anything to address the problem of jitter output from the ipod. will let you know, i own the msb platinum dac3 and a wadia 521 i want to who had the better soultion for the ipods so far i think its msb
