How to tame the midrange???

I am almost there with my system, except that the midrange sounds harsh, grainy, and exceptionally digital. Female vocals in particular. It actually sounds like clipping, but I can hear it at any volume level. However, the problem is more noticable as volume is increased. I listen to a lot of acoustic music with prominent vocals, so this is a real problem.
The room is 26 x 28 x 9. Furnishings are 6 piece HT type seating and carpet....nothing else. No treatments at all. I/C cables are Radio Shack's best. I plan to do room treatments and better cables last.
I am thinking a good DAC might smooth things out a bit. Or maybe seperate 2 channel from HT by adding a good 2 channel preamp with HT pass through. (the front speakers are already on seperate amps) Maybe a preamp with tubes. I suppose having the Denon CDP modified is an option as well. My focus is 2 channel. HT sounds good enough as is, and is a low priority. Budget is around 5000.00, but flexible.
The gear is:
Sunfire Theatre Grand II processor
Denon 3910 ....no mods
Classe Seven Hundred Mono blocks for fronts
Adcom 300x7 for center and surrounds (all bi-amped)
B&W 800N fronts
B&W HTM-1 center
B&W CDM9-NT surrounds
Another consideration is that I listen to Comcast Music Choice digital music channels quite a bit through their Motorola box. I think that makes a stronger case for adding a good DAC. I am new at this and rely exclusively on Goner's advise. Your thoughts are greatly appreciated.

Shadorne.....I did describe what I am hearing accurately, but I should have also said to what degree I am hearing it. On a scale of 1-10 with 1 being sweet laid back treble and 10 being harsh screeching, this problem is a 2 or 3. Not a blown driver or anything close. The problem does increase as the volume goes up. Would this indicate that it is the room? I do not know if room problems increase with the volume. The problem can be heard from normal conversation volume on up. I am super sensitive to this since I am having the same problem with an expensive car audio system I recently completed. I hear it in the car all day and then in the house. AAAARRRRRGGGGHHHH!
Robm321......I hear ya. I am getting to the treatments. It is interesting to note that I do not have a hint of glare or harsh grainy sound in my bedroom system. Adcom front end with B&W 805N and Velodyne DD12 sub. For critical listening, this system kicks my big rig's butt. I believe the "soft" room is the key to the sweet sound I get from this system. The heavy drapes and tapestries were there before the system.....the placement happened to be just right.

I own N803 and found the room acoustics to play a big role in the way these speakers sound. I use Echobusters corners and 8th nerve seems. Drapes behind the speakers and a rug on the floor. Seems that all these things do the job well. Also, and may be I am wrong, but I observed that if the amplifier can not drive the speakers properly then as the volume inscreases harshness will increase as well. But with B&Ws room treatment is a must! Also, bi-wire speaker cables help as well. B&W speakers when bi-wired just sound more balanced. Just my opinion.

Bafffled,

Ok I guess I may have been attributing a past problem that I had with your issues. Sorry if this was not really much help. Certainly if your car stereo has the same issue then it may be more to do with the way you perceive the music...again I reiterate that your speakers and gear are excellent...so my next suggestion would be an equalizer ....6db down at 4K is well known to reduce what is pecieved as harshness in the mid range.

Baffled,

I own TAG McLaren FYI but you can do it GMood's way and since I live near Silver Spring MD, I have no problem coming with a Meridian processor and show you what I'm talking about once you have your My-T "2 channel rig" going.

I'll bring some tissues too.

PS:"or just not that well informed." think you know enough to judge who knows what? :) email me anytime.

An equalizer? That's a drastic solution. I would only consider this if you're willing to kiss off resolution and collapse the soundstage. There is so much to address in this system: cables, room acoustics and speaker placement that could very well resolve or significantly reduce any number of problems identified here.

I think it is great that there is someone near you. I would certainly take the offer from velocitydls and hear his Meridian in your system. But I am with GMood1 on this one. For multi-channel digital sources, movies, etc, the Meridian could very well be a huge step up from your processor. But when you insert a tube stage in the loop in place of the Meridian, be prepared to pass the tissue box over to velocitydls. Any number of models in the $2000-3000 range on the used market like the ARC LS5, LS25, BAT 31SE, BAT 5, Aesthetix Calypso, etc., will bring on a level of musicality to the 2-channel presentation that no ss multi-channel processor can even begin to approach. Try and borrow some cables from your dealer to use for these tests too. The line stage to amp link is critical.
