I auditioned both Purist Audio Design Musaeus - Praesto Version, Kimber 8tc, and Synergistic Research SE Active Core (I used the silver module for most of my listening) from the cable company. I bought the PAD Musaeus - Praesto Version. In my system the DAP excelled over the others in instrumental timbres, imaging, and dynamics as a result of its black background. Here are my overall ratings for each cable:
Purist Audio Design Museaus - Praesto Version: VG to E
Very black background with pinpoint imaging
Outstanding Instrumental timbres
Sound stage is a little flat. The sound stage deepened as the cables settled in but they still did not reach the 3 dimensional depth of the Synergistic Research SE Active Core.
Synergistic Research SE Active Core (I used the silver module for most of my listening): VG
Wide and very deep, three dimensional, sound stage
Excellent dynamics and instrument attack.
Well focused images but not as tightly focused as the Purist Audio Design Museaus Prasto
Timbre: There is a coloration that homogenizes the timbre of instruments (especially acoustic instruments). This homogeneity of timbre lessened as the cables stayed in my system but never completely went away.
Haze: there is a little haze between (or surrounding) images. Consequently, these cables did not produce the black background and pinpoint images of the Purist Audio Design Museaus Prasto.
Kimber 8tc: VG
Very large soundstage with good depth
High frequency response was outstanding - almost magical
Very good dynamics
Slight homogeneity of instrumental timbres.
The large sound stage was at the expense of imaging. These cables lacked the imaging of the Purist Audio Design Museaus Prasto
