Hello all. I see people posting all over the place that in order to get the best sound for your buck..you need to invest in a SPL and an Avia Disc.

However even if i went ahead and bought these two items..i would have no idea what i was doing with them nor would i have any idea where to get information on how to use them.

Or EVEN WHERE TO BUY them???


Can anyone shed any insight on these items and how to use them..or point me to a place where i can find information on how to use them.
