Thanks for the info.

My only concern with those competition systems is budget. For pros probably they can differentiate system to system. Definitely not me. Im looking for entry level to medium ice system that heavy on vocal and clear audio. Im not a fan of 'boom boom boom' aka bass.

As you said, too many good sounding, so could you recommend any of those that meets my criteria?

I was thinking to get below 2k systems. So i would like to fit in HU, speakers and amp. Not sure I can get decent one tho. But anyway, already saw your blog and the HU looks good. Not sure about the sound since it was recorded and not live.

Clarity vary from speaker to speaker and setup too. The closest example that I can gives are the goodness/clarity of in ear headphone klipsch Image S4 or VSonic GR07. Not sure if you are a fan of in ear headphone. Im satisfy if i can have ice setup that can produce at most close to that quality. Of course both are in different area, but just a example to let you know that the target that im looking for.
I know edifier build pc speaker but never heard before they involve in car audio system. Probably wouldnt hurt to go and see what edifier can co.

Im sure this Edifier guys will try their best to bring good sound because they were eclipsed by the PC brand speaker so yea they have a reputation to forge in ICE world. Those earphones you mentioned are not pushover you know especially the GR07. So to get that much integrity inside a car is gonna cost much because you see the car wasn't made sealed properly unlike your earphone. Yea other option is howiechoo @ EA Autoworks. He's been on the list there in EMMA. Do take your time to drive a bit further, take peoples' advice with a pinch of salt because in the end it's like audiophile peeps used to say "I'm sorry about your wallet".

Yo Edifier, build a demo car and smacked everyone in EMMA next time, there's your ticket to glory. I have no doubt you can pull it but I see that a lot of people doubt the brand's sound.
