2009 e70 base sound

Well, I have a downgraded system on my x5 (4 middle range speakers and 2 subwoofers, no middle channel) and the clarity of sound is very disappointing. As I did not want to spent 4K to do a complete aftermarket upgrade - decided to go with BSW solution and upgrade speakers as the first stage. The quality improved but clarity is still not comparable to a base e65 system.

I understand that BSW solution is build "on top" of original BMW sound schema where signal is already modified on pre-amp/amp level to match with OEM speaker specs.

While BSW stage 2 amp solution (where they would probably still need to reverse BMW specific pre-amp filters before applying custom settings) is still in works and it is unknown of when final product is going to be available I am looking around.

Anyone on the forum modified their base sound system to the acceptable clarity level at the reasonable price? Any experience you can share? In my research I found Reus Systems as well as Aidesign but their solutions costs more than I want to invest in to this project.

Also, wanted to share an interesting link - MOST Digital Pre-Amp: http://www.mobridge.us/products/most-digital-pre-amp
