Just spoke with Jonathan at Little Labs for some direct input.

A completely honest guy... I came into this splitter thing thinking I can get the exact sound of my 20 ft Monster Cable plugged direct into my amp. I was plugging from the guitar to STD purple cable to STD box through two 20' Monster ables into two amps. The impedance changes at the 1/4 jack of the purple cable so he mentioned that I try to connect the Monster cable to the guitar first and then use a barrel connector to connect into the purple STD cable then thru the STD box to the amps. This would give me back some of the Monster cable tone. There are a lot of things at play here and so the tone is bound to change.
Bottom line is I can let up with this quest to get the exact tone of my Strat through a 20' Monster cable plugged in direct. Instead I should look for a tone through a splitter that I can like equally as well...
