where in socal are you located?

i can help you tune your system.

i have used it on the alpine pxa-h900 processor and the pxa-h701, its a POS. ear is much more accurate.

 

simple mathmatics is more accurate! lol.

All you have to do is some measurements and setup the TA.

I personally feel TA makes a huge difference. It is one of those things that once you have had it...you never can listen to music any other way again w/o missing it.
