I can't help you with the cabinents as I do not know much about veneer. As far as the sound, I would say give them a little more time to break in. My son (his speakers and they are the 2Pi Towers) mentioned to me after about four days "they sound better". I did not know that his hearing was that attune to hearing fine nuances in the music, in fact netheir did he know anything about "break in".
Also the 2Pi is not hard to place in a room, but as with any speaker placement can help or hurt (with some speakers more than others). Keep moving them if you have the ability to work with your room.
After you get them placed correctly then if you are still not happy with the sound then I would look into some room treatments, many listeners overlook room treatments and continually change equipement to try to find the ideal component or combination. I would say in many instances that looking at some room treatments is what will be the answer to the problem in the sound.
Good luck and enjoy.
