B&W 703 - How to tame the highs?

Why tubes? Tubes are not a panacea. Do these tubes make sound prettier than in real life, is that what you are in fact saying? High frequency roll off maybe or treble softening? So, if that is the case than it is the coloration of tubes you like. So it appears tubes have an euphonic coloration. So this will upset many tube gurus who say that tubes don't have audible coloration.

Change the type of music I listen to. Not likely to happen as I grew up listening to the popular music of the 70's, 80's and 90's which was mainly Rock.

Actually most of the 70's and 80's rock music is fairly good - apart from Steve Lillywhite stuff and a few other "headbanger" producer/engineers. It is in the late 90's where is starts to get really bad and unlistenable on audiophile quality gear.

May I suggest a PEQ? You can program a PEQ with several curves...one to suit compressed rock music, for example with a broad 6 db dip around 3 KHz and going from 1 to 5 Khz. Whilst storing a different curve in memory for "Eva Cassidy high quality" type stuff and for when you watch a movie (movies are deliberately mixed to be dynamic as they are targetted at good cinema systems not car radio listeners). That way you can have your cake an eat it too!!

Another alternative would be two sets of speakers...A and B and switch between the two depending on your mood/requirement.

Unfortunately
1) there is no way to fix awful recordings...of course it begs the question why bother with a costly system to listen to awful recordings when anything cheap will generally do better.
2) while you can PEQ down - it is much harder to PEQ UP with good effect - I won't go into detail but it tends to sound better in the down direction which makes a transducers life easy rather than the other way round - so if your speaker has no midrange to start with then it is hard to correct as it may be a transducer limitation due to compression or an inherent odd radiation pattern - whilst a speaker with flat midrange and good dispersion can be easily EQ'd down a bit to get a desired effect.

I have owned B&W 804S speakers and I did not have a problem with highs at all. Those speakers have the best highs I have ever heard. They are there but not harsh even when played loud. The 804S's were a bit mid-rangy though. The bass was quite good. I played one of my Poison CDs which has a heck of a bass note in it and they handled it incredibly well. My preamp and amp are Adcom and my CD player is a Carver. That equipment is around 15 years old.

I have high frequency hearing loss but can still tell when highs are not smooth, and it seems to be the actual recording that makes my 703's harsh sometimes. I got some coarse black cotton mesh and lined the metal mesh tweeter caps with it and it helps the offending program material, although most of my listening is done with the protector caps off altogether. I use Audionote silver I/C cables throughout (AN-V and Sogon 50), and a double run of Vintage Polk Audio Cobra cable to the 703s with the brass jumpers in place(not biwired). My electronics are Simaudio Moon Evolution Series I7 integrated amp and and CD player, and a Dynavector Karat 17D3 MC cartridge on my Pro-Ject 2 experience. Phono stage is Simaudio Moon also.

I to have the 804s and do not find the highs to be to bright at all. If you have a bad recording you will know It. The amp plays a big part on how the B&Ws sound. I run all Krell and I find It to be a good match for the B&Ws. I will say the more clean power you give them the better they will sound.
