Arguments based on defects with other peoples hearing or systems are totally unsubstantiated since the system in question have never been heard in support of the argument. Its not even an opinion rather a conclusion based on no actual fact or information other than a belief or assertion that the fuses must always make a difference which of course can never be proven, only that they can or may in certain cases.
Attempts to discredit or even chase away those with different or unpopular findings in my mind in fact discredits the accuser, not the intended victim. Its a reaction based purely on emotion or some other agenda and holds no water whatsoever. Pure bully tactics.
My issues or reservations are with Synergistic Research and their products discussed here specifically. I have not observed the value as a pricey (as fuses go) upgrade over the fuse provided in my Audio Research pre-amp in my particular case. That’s it.
Also I would tend to not buy products from Synergistic Research specifically based on my experience to date and assessment of information provided by SR on their products to date. That’s my judgement call based on my experience. Others obviously love their stuff.
