i have had them for about 10 years and I like their clear and accurate presentation. They are driven by big Boulder pre and power amps to give lots of control and they do excel in the midrange and high frequency stuff - Miles ' trumpet sounds fab they are very true to the original sound in my opinion particularly for natural instruments - piano, brass, strings, woodwind and human voice - they are pretty good with rock but that's not really my main focus although I do enjoy rock in which case I tend to use vintage12 inch red Tannoys (driven by Leben) for that or my Loth-X Polaris full range (driven by Viva 845 in winter or Croft Twinstar 4/5 in summer) which are a very natural and involving listen and play everything well - whoops I am digressing here!
