Why am I experiencing listener's fatigue?

Oh...also, in your room it might be different with toe in. I said about a foot in front of me but I did check and they just cross in front of my face, not a foot, but may be 3-4 inches in front of me. But you know you have to experiment. And the funny thing is, when you move the speakers, the cables get moved as well, right? That is what you also have to consider - after you move the speakers, have them play for about 45 minutes to an hour before you evaluate them again. I noticed in my system that's the case - speaker cables need their time to come back to life again. May be that sounds crazy, but just what I observed in my system.

from the manual for N805... same as on my manual for N803. They recommend shotgun bi-wire cable. Which I think is the way to go. Check it out.
"All connections should be made with the
equipment switched off. There are 2 pairs of terminals at the back of the speaker to permit bi-wiring. The lower
pair feed the bass/midrange drive unit and the upper pair feed the tweeter. The terminals are insulated to prevent any likelihood of electrical shock, even when the speakers are used with the highest powered amplifiers, and accept a variety of cable termination to suit most applications.
Bi-wiring is the preferred method of connection and involves the use of separate cables from the amplifier to each pair of terminals. The separation of the signal paths improves the resolution of lowlevel detail and allows the user to optimise the type of cable to the frequency range of use.

Should you not want to bi-wire, perhaps
during the initial set-up procedure or
because you do not want to see a
multitude of cables in the room, short
cables are provided to link both positive
and both negative speaker terminals
together.
When using the links, insert the spade into
the slot in the side of one terminal and the
crimped pin into the round side hole in the
other. There is enough clearance to insert a
spade connector from the amplifier into the
same terminal as the crimped pin.
Ensure each positive terminal on the
speaker (coloured red) is connected to the
positive output terminal of the amplifier and
negative (coloured black) to negative.
Incorrect connection can result in poor
imaging and loss of bass.
When bi-wiring, do not use the linking
cables. Take extra care with the polarity of
the connections as incorrect connection
can also impair the frequency response
through the bass-midrange crossover and,
if the links are left in place, may cause
damage to the amplifier by shorting its
output terminals."

"improves low level detail" what is low level detail? I mean it seems self explanatory. I do find myself wanting to turn up the volume because at levels which are probably more comfortable i only get certain parts of the musical presentation. It is as though there are things I just know are there because i am familiar with a track or cd but am not hearing them at the level i am listening at, so i turn it up. Turning it up seems the only way to get at that info. Now i know that a good test for any system and especially an amp is its ability to present the whole frequency range at any volume or at least low volume. In other words it will play quite quietly and still give you the whole spectrum and maintain the integrity of the musical presentation. That is what i've gleaned from the internet and have come to accept as true. It could be wrong but i dont think so. So, anyways what i'm saying is i that i do think that the symptoms you describe are there in my system and that I'm turning it up too loud to get "everything" out. But not just that but bi wiring could get rid of at least some of the listening problems i have. IF you were able to change all that by bi wiring than that is what i'll need to do too. I am taking a huge break right now from listening, so everything will have to wait a while. thanks for the follow ups.The b&w story was great! Yes the 805's are pretty amazing when they're done right. They sound absolutely amazing to me but i have this problem. If anything is there downfall it would be there ability to match up, since they seem to be very specific about what they want. Is my understanding of low level detail correct?

I'm not an expert, but I think you understand it correctly. Could you please keep me posted on what happens. I am just curious what will be the solution for you. thanks

Just a follow up to this old thread. I recently bi wired the 805's with some plain speaker wire.( I sold my cardas wire ). This helped take out some of harshness in the treble to my surprise. Anyone reading this who has bw's should bi wire them and follow just what the manufacturer recommends. Another thing is the stingray coupled with the metal tweeters on the 805 i have read by an interviewer that this could in fact cause brightness. This also could be a contributing cause. Also i think the concrete stands are highmass which can be a good thing but one thing they dont do is dampen. I think since the 805's have threads in the bottom of their cabinets that they were meant to be coupled to a stand to transfer resonances and have them damped. I think heavy stands filled with sand and coupled to the speaker is the best situation. The blu tac i was using was probably too thick as well (the size of a pinball ) This i think isolated the speaker. A very very thin layer of blu tac would be better so that energy can transer to the stand but in the case of concrete even then there wont be much dampening. All this might effect imaging but perhaps this might be another possible culprit for the fatigue i was experiencing. A cardas golden reference interconnect helped too , as my diy interconnect i suspect, is a bit forward and harsh. Also i have logged another 150 hrs on the speakers which saw a more tonally balanced sound emerge. The woofers on these things are so rigid and well built that i would bet there are even more breaking in thresholds ahead if you have the patience to wait for them.

Summarizing: likely culprits:

not bi wired, manley / metal tweeter bad combo, poor speaker mounting, bright interconnect, speaker not fully broken in, turning up volume too loud to try to compensate exaccerbated the problem and symptoms
