Getting rid of harsh, shrill treble


I cannot play my classical cd's at a volume where the midrange and bass come through without harsh, shrill treble, especially the violins. I have bookshelf speakers on stands and subwoofer in a small 120 sq. ft. room. I have no treble control on my pre-amp. I tried a Taddeo passive Digital Antidote II between my CD player and pre-amp with minimal result. I have a solid state integrated amp, will switching to a tube integrated amp cure this problem or is it my speakers?

I have been reading about the Magenta ade-24. It is a device specifically designed to reduce this problem. It is an analog device that would go between the CD player and the preamp. For $250 it sounds like it would be well worth it to try it. That's a lot cheaper than most cables people will suggest.

You didn't mention if you play LPs. If you do, do you have the same problem?

Here is a review of the Magenta unit: http://www.hometheaterhifi.com/volume_6_4/magenta-ade-24-analog-digital-enhancer.html
What preamp do you have?

I have heard this symptom before many times, including in my own system.

A tube preamp worked wonders for me, and many other people as can be attested to on this forum. There are many flavours of tube preamps, from very neutral ones (similar to SS), to very coloured ones (warm).

It would be an easy test to borrow and swap in a tube preamp and see what you think of the sound.

I can't recommend a tube preamp enough to remove shrillness/brightness, and to get great sound in general!

Gentleman,
Got a pair of Ohm Walsh Micro Tall's connected to a Jolida JD100RC integrated amp. I am in the concert hall!!:) Thanks for all your suggestions.
