B&W 803D and Parasound

Your problem is simple you have a way too expensive speaker on cheap but good amplifiers, the general rule in audio is that the electronics cost the same to twice the cost of the speakers. So if you are using a $9k speaker you need way better electronics then what you are using.

Now then I have to ask what is the rest of your gear, if it is of a similar level of quality why did you invest so heavily in the speakers without realizing that it is the quality of the electronics and the resolution of the source which makes the speakers sound good, you can take a cheapie pair of speakers and play them on really expensive electronics and you will be impressed, but the opposite does not hold true.

A tube preamp and a W4S amp would be a better combo. Then too, how the speakers are set up for bass balance and toe in can make a huge difference as well.

They are the prior version,not the latest Diamond series. I am looking at the possibility of power cables as a potential, the only thing I have not looked at.

Done with cheep speakers,etc..I had a pair of Infinity SM150's which were good rock & roll speakers and took a serious pounding from the Parasound equipment over the years. I decided to upgrade being that I listen to jass and auditioned several speakers...The 803's are well worth the money if you have the right equipment driving them. I just have a hard time believing that Parasound is solely the sorce of my problem.

when i first got my 804S they were connected to a pioneer elite receiver and the sound was very harsh... i did a separate amp with the pre outs from my receiver and the harness went away...

i do not know about the parasound first hand, but i do believe there is a point to an amp making the difference..... but not to the extreme of crazy amounts of money for an amp.
