Getting rid of harsh, shrill treble

I think Rodargent has a very good point. The treble on some CDs is extremely shrill and after all this time I still think, what the hell's wrong with my stereo and get pretty disappointed with the sound. Then I put on a well recorded CD and ahhhhhh.... So there are Cds that for me at least are almost unlistenable. Unfortunately I like the music on some of those bad sounding CDs.
So a lot of this problem can be software based. Of course, if the treble is always harsh then you probably have a hardware problem. A bad CD on such a system can leave one seeking shelter and give you a negative attitude about audio in general.
Reasons IMO some CDs sound bad is the technology used to record them in the first place. Recordings made when tubes were just going out and being replaced by early solid state can be harsh. Also early DDD digital recording can sound nasty but with no tape hiss:^). Authentic classical instruments (which I like a lot) recorded either way can sound extra harsh.
Classicalfred, have you noticed some of these problems with recordings of specific eras? Also you might want to audition some tube buffer stages, preamps or CDPs with tube output stages and/or warmer cabling.

Digital sources have been a major contributor to this problem in my systems as well. A nearly jitter-free digital source can be a revelation. I don't know if your source can accept, or is worth adding the newest generation Audiocom Superclock 4, but you may want to consider it. Steve Nugent at Empirical Audio recently installed one in my transport. Given the list price of the stock unit you'd think it'd been engineered to the max - well, not quite. Good digital is apparently very hard to achieve, and the price tag alone is no measure.

Tvad,
In another thread these speakers were recommended to me. I have not purchased them yet, but am auditioning them for 120 days to hear if I like them. So far so good.

Tvad,
I have a Sunfire Super Junior sub placed between and slightly to the right of the Ohm's. I can't tell you how warm these speakers are getting as they break in. It is an incredible deep three dimensional soundstage, with plenty of bass, and warm non-harsh treble. You have to understand I have a 13'L x 13'W x 8'H listening room. This sound is the case, even on my very old CD's such as EMI label, Otto Klemperer discs of Wagner Overtures, Brahms Symphonies, etc. Archiv, with Reinhard Goebel and Musica Antiqua Koln used to be so harsh in treble I had to turn the volume way below realistic levels. I agree with Jb0194 that my CD's are the problem, but with different speakers and a tube integrated amp I have solved at least 50% of the problem. I had what is known as the magnesium midrange/bass cone ringing problem. If you don't believe me just Google "Magnesium cone ringing" and you will see. Many people, not all, experience this with both Jamo and B & W bookshelf loudspeakers. The Ohm Walsh talls use a polymer coated midrange/bass cone and tweeter. B&W uses an aluminum tweeter and Jamo uses a magnesium midrange/bass cone, making for harsh/shrill treble. I must admit that the Ohm's are not as detailed as my Jamo's or B&W's were. This is especially true on complicated orchestral passages where the entire orchestra is playing; but the deep three dimensional sound stage, liquid midrange, and warm treble are what I enjoy listening. My 26 year old son, a physics undergrad major, and masters in computer science and engineering says I am out of my mind and that I imagine a difference in the sound, however, I hear it loud and clear. I have forgotten my equipment now and am enjoying my music collection. The only equipment I still might replace are my speaker cables (I need an 8' run for each). What in your opinion is a "warm" speaker cable brand I might look into?
