Hi George,The cat9E is a good poor mans Kimber cable but well worth the effort (as advise by Zilch god bless him).Like all these things if you cant hear the difference your problem lay elsewhere.Not one to be contraversial but assuming a straight wire connection charge coupling Solen Fast caps to the signal path seems to add back a glazed electronic signature not there in the firdt place. Nice way to try and recover a lack of true detail and resolution.No flames please. Just as an observation in imhoIan
