Most of those who say you must have a preamp don't understand what a preamp actually does, how the output of a source interacts with the input of the amp, how the volume control enters into the picture. etc. It is a complicated situation but eliminating an uneeded gain stage will ALWAYS be an improvement provided careful attention is paid to matching everything else. However, if you need the extra gain or your preamp-power amp impedance isn't a good match or you try to use too long a cables or cables with high capacitance or for other reasons an active pre might make your system sound better. Evidently yours sounds better without.
You frequently hear people say their system is more dynamic with an active preamp. It isn't because the pre made the signal more dynamic, it was becuase their source wasn't able to properly drive their amp through the cables and passive they used. A passive system can be just as dynamic as an active if properly implemented.
I don't really understand what you are looking for with this thread. If your system sounds better without the preamp then be happy and enjoy. If you are ineterested search the forums for passive preamps and you'll get more than you ever wanted to know.
