Advice on system and speaker placement-B&W

My system is the following:
B&W N804 speakers
Musical Fidelity a3cr pre
Rotel 1080 Amp (200 watts/channel)
Cary 303-200 CD
Harmonic Tech Truthlink Interconnects
Tara Labs Prime 100 Speaker Cables
System running for three years now and fully broken in

My room is 20 ft wide, 35 foot long and 15ft high, along the right 35' section, there are several large openings into other rooms, along the left side of the 35' opening there is a large opening into the entryway. Speakers are 10 inches off the 20 foot wall and 10 feet apart (I can't move the speakers out further into the room).

My system sounds wonderful on well recorded rock, jazz and classical, but many CDs sound thin and uninvolving, with too much highs. Does anyone have any advice as to how to make my system sound better for the other 65% of my recordings? I have started other threads on this topic, but without the whole story on my room setup. I am skeptical of expensive changes to amp/preamp because my system sounds just great on 35% of my recordings. I could use a sub, i could look at new speakers (i like a rich full sound but with dynamics), or maybe an extra CD player (that is easier on the recordings-but not sure if this would be enough to solve the problem). I know this is a complicated question, but there seem to be many of experienced folks out there. Anyone have a simliar situation or setup and advice? Any help would be appreciated.

I really think you have an issue with speaker placement. I also have N804's. However, they are currently in a dedicated listening room (15'x22'x9.5) , so I can place them anywhere I want. I found that using the Cardas method really works out well. Speakers are 6'-1" from the front wall and 3'-10" from side walls. Spacing is 7'-4".

For the size of your room, the 804's may be a bit small. You might move up the B&W line to the new 803S or 803D. Actually, any of the larger B&W's would work. Given that you can't move the 804's and considering that you may not want to drop 8k for new speakers, you could try a tubed preamp and see what that does to the sound, imaging, dynamics, etc. As someone noted above, they do respond well to tubes, so if you like the results from a tubed pre, then you can try a tubed amp. I am using a tubed pre and SS amp(VTL 5.5/Krell 2250). BTW, I doubt that your CDP is the cause of this. Hope this helps some. Good luck.

Thanks for the input. Midrons/Chris, I tried a cary 308 tube preamp with the Rotel amp and it helped but was still glassy on top. I also tried the BAT VK-300 (not tubed version) and it wasn't any better than my musical fidelity/rotel setup. I'm guessing I need to think about a more foregiving speaker here (placement and bad recordings). But pls keep the thoughts coming.

Its interesting that the issue of tubed amplification came up. It hadn't occured to me before. I've been using a very good tube pre with SS amps

You didn't mention how far back your listening position is. If there is any way to get them a little further out, then I would do so. I've alway used the 1.5 rule (or manufacturer's recommendation) when first setting my speakers up and experiement from three. If your speakers are 10' apart then your listening position should be about 15' from each speaker. I also tow mine in so they point to about 6" to the side of my ears while seated in my listening position. This works well for me with speakers that have good dispersion. However, some spekers sound better towed to a point just in front of the listening position. Just some things to try, but you'll just have to experiment and see what works best in your room. BTW, setting them up along the short wall is best IMO.

You do have a dilema. I would think that the BAT would have smoothed things out. Are there enough dealers near you that you can bring any demos home and try them for a weekend? That way, you can listen in your environment.
