Many thanks for the feedback on your trial. May I ask if you tried the CH Precision L1 preamp with X1 power supply? Were there any other noticeable differences apart from transparency e.g. timbre....was the Dart preamp richer sounding? Many thanks
Yes I tried L1+X1 .As the testing period was short I did not try L1 without X1.
I have been able to compare 3 top swiss preamps : L1x1, Dart and Soulution 725.(and I used to have Accuphase c2850)
In a nutshell, all fantastic preamps with great drive and transparency .
Soulution : a lot of drive and dynamics. Dark tone
Ch p : fast, clean, soundstage precision and.details, probably the most transparent. Neutral tone.
Dart : also fast but not.as.fast as the previous ones, a lot of details as well,.clarity tone a bit "tilt up", probably the best for the midrange. Supposed to.have excellent phono input but I.am not into tt.
However works (much) better with the zeel or rca inputs /outputs and the synergy with non Dart amps must be tested. You can have some hiss as well.
So to me you absolutely need to listen in your system . Dart pre is probably a bit more sensitive than CH Precision to downstream/ upstream gears but if it fits it's an infinite source of pleasure !
