I have NOVA V's and I am not happy


I have a Mark Levinson 585 and a pair of Sonus Faber Olympica Nova V's and although I admittedly have some room acoustic issues that I am working on I am not happy with the sound. 

I listen to music LOUD. This Pairing thru a pair of Kimber Cable 8TC's gets bright in what I think is the 2 to 4 khz range and the sonus faber nova's seem to mute the lower end of female vocals, artist like Macy Gray or Tina Turner dont seem to have the same drive in the lower octaves. At the same time the upper end of vocals like Sheryl Crow can get too bright and cause fatigue (I am assuming this is in the 2 to 4khz range) I have tried every speaker placement you can think of, toe in, toe out. distance from front wall and I am adding acoustic treatments as fast as they can be shipped. 

Here is my question, I had Mark Levinson 436 Mono Blocks in the past connected to a pair of B&W Nautilus 802's thru a pair of MIT Shotgun bi-wire speaker cables and I never noticed that system to be bright. Granted that system was in a different room in a different house. Everyone is telling me that B&W is a brighter sounding  speaker by far over Sonus Faber. If I decide after all my room treatments that I am not a fan of the Sonus Faber sound where should I turn for my replacement speaker? Or is it Mark Levinson's Fault? I want Rich Lush Loud Musical sound. I like a decent sound stage, I also really love it when when you hear decay from the instruments. I don't really care if that's what is neutral or not that's what I like :) 

Where did I go wrong and what can I do to fix it?

Thanks Lee

I think most good systems get bright as you listen very loud since the higher frequencies hurt your ears.  Especially as your ears age.

Earlier this year I overcame similar symptoms - obvious non optimal  acoustics, glare and a weak lower register.  Fatigue at anything above background music.  It wasn't a speaker thing (AZ CrescendoII) or an amp thing (Pass Labs), it was a synergy thing.  Then came a Luxman L-505uxii.  It rocks instinctively where and when it counts, on time, bold, propulsive, giving blues/rock and blues a meaningful life.  (I love blues, rock and blues, in that order. : )  Loudness button gives a kick in the bass.  So helpful with bad recordings and especially radio.  

I'll spring for a used 509X some lucky day.

Kenjit, I appreciate your reply and although I am sure you experience many unreasonable customers daily I am not blaming anyone nor am I asking a company to custom design a speaker to my ears. What I am asking is what combination of equipment create a sound closer to what I described than the equipment that I currently own. 

Thanks Lee 

Your ML gear is not bright from my experience. The 585 and 436 were on the slightly warm side of things when I heard them with Magico A3 speakers. I also feel the B&W are brighter than my comfort level, and the Sonus is darker than my comfort level. So given that and also your observations I would think it is your room acoustics that is making the sound bright.

We see complaints like this all the time. Your speakers were not custom tuned to your ears. They will need to be retuned or you will need to buy another speaker but the result will be the luck of the draw.
