Wow...I have had the Vitus ss-101 that was replaced by the Dartzeel amp 108 and the preamplifier 18 and kept them only 5 months. In the beginning I was happy to listen my Avalon Eidolon Diamond with Dartzeel and after these few months I understood the limits because the music seems all the same and was not enjoable anymore. I had the opportunity to listen in my home the Burmester 911 and the preamplifier 077. Now the sound is excellent, a lot better than Vitus and Dartzeel, something that you can't never get tired when listening and this happened mainly with Dartzeel where a lack of emotions were far from the music hearth. Besided I prefer also Vitus to the Dartzeel, but I ran fast to replace it very soon. The bloated midrange of Dartzeel could surprise when you listen for the first time. Now, with the present Burmester components the sound has an appeal to the deepest emotions and captured my soul with a natural awesome dynamic authority. I demoed in my system also Pass xa160.5, Spectral 260 and the Krell Evo 302, but the Burmester 911 is for me the ultimate in sound quality. Now my Avalon are singing.
