Hi Chenglo, Here are some additional questions:
* what are your amp power requirements...
* What speakers are you using, and what is their sensitivity....
* What are the most important sound characteristics for you...
* What music do you listen to?
* Realistically, what is your budget ceiling?
Regards, Guido
