Whats my weak link?

Screams power cords to me, Acoustic Zen used by Classe owners I've known. Zu perhaps also. The MAC power cables sold on here are nice too.

If you try power cords, get some from somewhere with a good return policy or for a dealer thatets you audition them. Heck, good advice for most gear.

But the DAC is what came to my mind first.

It just might be his listening room .You could be spinning your wheels by replacing gear.Have him bring his gear over to your house and then you can determine what you need.

B_Limo,

Just asking, what are you doing?

On March 1 you buy Vandys. Four days later you buy KEFs.

So what are you doing? More importantly, where do you want to go and how much money do you have available to try to get there?

Honestly, it sounds like you don't know, but what you do know is when you hear something better, you want that sound.

Tmsorosk told you that the synergy of the components is the thing that makes or breaks a system. You assumed that the KEFs were the winning factor in your friend's system, but they didn't do that same trick in your system, so it's not just the KEFs alone that gave your friend his sound.

Do you have a dealer nearby who can help you? It appears that you're flying blind and all you're going to do is keep on spending money with no plan in place.

YOur room probably has different acoustics than the other guys. Have you played with speaker placement and orientation to get them locked into your room? Gotta do that first to get a good baseline from which to judge what aspect of the sound, if any, needs to improve and how best to achieve that.
