What to upgrade next?

Out of all the suggestions so far I would tend to agree with Bidkidz. I myself have went through a number of power
conditioners,cables,power cords,digital upgrades. And while
they have all made nice Improvments in the sound, Changing
or upgrading speakers in the line you already have will
make the biggest difference.

Upgrade the room. It will make more difference than replacing the whole system. Most sonic annoyances are created by the room, not the system. I have found the information available from Rives to be incredible. Check out http://www.rivesaudio.com and see what they have to offer.

Yes the room treatments and set up are also key, sorry I left that out (stupid me)but in the end the speakers will limit the system sound to whatever they are capable of. The system sould change significantly with Vandy 5As versus all the treatments that I know of. Depth in my system became more real when I used a speaker that was capable of adding lower bass and extened highs. Treatments are a key system concern too.

Happy Listening.

Remember, a speaker will never reproduce what doesn't get there from the front end, therefore all things being equal speakers are the least important componant in your system. No speaker will have a good spectrum of sound, good imaging or soundstage in a bad room.

Mediocre speakers can sound good in a great room, but great speakers will only sound mediocre in a bad room. Treat the room and you will have a better stereo.

Your system looks great.You are ready to take the plunge.Room acoustic treatments.The easy one is the first reflections.Sit in your listening chair,have someone hold a mirror flat to the wall on the right side and left side of your speakers until you see the tweeter in the mirror.Those are your first reflections.They will reflect sound fractions of a second after the sound leaves your speaker.Take a couple of couch cushions and put them on those points on each side wall and you will notice something very different.Do the same to the ceiling.Hold a mirror flat to the ceiling until you see each tweeter in the reflection(there will be two spots on the ceiling unlike the single spot on the side wall)Take a couple of pillows and four drywall screws and screw each pillow to the ceiling and see what you hear(your wife about to cut your stupid thoat).These are your first reflective surfaces.It costed you about an hour and eight drywall screws to see that the acoustic treatment police will soon arrive.Good luck.Patch up that ceiling too!
