Well the verdict is in on Bryans much modified Line Magnetic LM-502CA Dac. All had a similar tale to tell, First the standard Line Magnetic LM-502CA Dac. On sound quality is the standard Line Magnetic dac worth buying, universally the verdict is the standard machines are only good to OK sounding, some hardheads thought they just aren't good enough, but considering the $1000 price tag they are very tempting, As to the question, on a well tuned wonderful sounding system is Bryans much modified Line Magnetic LM-502CA Dac a killerdac killer, They clearly say NO. I think on any given system in various states of tune any DAC can appear to be the best, but eventually over time the answer is there.
