disguy409 is the one who has decided to go with this system.
You have to go with what your pocketbook can bear.
Trying to compare those two systems are like night to day. That yamaha system is 8-10 times the system you have. But it is 6 times more in cost too.
There are tradeoffs we all make based upon what we can afford.
Dont worry, stay with what you can afford and build from there.
