Or if your system is already stunning, then it will not make 1800 euros worth of difference, or whatever the price is... it will make no difference
APL technology has changed mind of many enthusiasts despite their pervious experience in the audio World. Carsound is not an exclusion.
Sure, 1800 euros is a lot of money and one has to think about before investing in new components... But let listen first to what APL technology could make before final decission.
APL1012 for sure is not for newbees, but with the help and support from Raimonds, nothing will be impossible even for them.
But again, perhaps it is simply a wrong timing to change the stunning system. Especially if you made it by yourself and now it is time to enjoy it. Fully understanding you in this point. Good luck!
