Jugi63,
I recommend you just do a search by entering Shindo and look through the past threads, do the same with VAC lots of info. There have been past discusions in relation to this but that being said your ears are still the ones to be satisfied. It's going to greatly depend on the rest of your set-up etc. so always best to get what ever it is that interests you into your own set-up to evaluate.
Best of luck and enjoy!
