"Now we know what the RX in RX Technology stands for; - (Real eXperience).  I thought it might of been "Radical eXtreme" sound technology or "Revolutionary eXtended" sound technology.  'Real eXperience' doesn't cut it if you ask me."  That term doesn't really define any cohesive definition of what really makes up the RX technology.  
Real eXperience??  What is that suppose to mean???      

      Oh well... 
Also; you will almost need a crane to lift it.   

  It weighs 3 1/2 lbs. MORE than the 76 Key Pa1XPRO does.  

Best regards,
Mike
