Well, I paid my deposit on the new Dart pre amp early in December only to be told later that Herve´ had sold out of all the current production and had run out of parts to make any more – it would probably be April before production starts again, so those of you who managed to get them, count yourselves lucky!
However there is a silver lining as I managed to obtain the Ypsilon 100 mkii pre (passive version) and VPS phono stage instead. The Ypsilons are cheaper here than in the US whereas the Dartzeel is more, don’t ask me why.
I was able to borrow the Ypsilons to compare with the Dart - it transpired they produced a preferable sound to my ears. I was a bit surprised as I felt the NHB 18NS was the last pre amp I would use, and probably would have been, if I could have got hold of the new version. Maybe the new dart is comparable (better even?) to the Ypsilon pair, however, I will never know.
The main thing is I have been able to make a significant upgrade on the original Dart which was the object of the exercise when I decided to go for the new version when it was announced a while ago.
On first listening the overall instrument tone, dynamics, frequency extension are very similar.
After extended listening to the Ypsilons everything sounds that bit more real, less mechanical. Instruments have an extra dose of fullness and naturalness. Vocal lines have slightly more inflection and emotion.
During the time I had both units I observed better separation of instruments/players, more instrument tone, there seemed to be a lower noise floor as well, low level details became more apparent. Overall the Yps adds a bit of ripeness and texture, colour? to the sound. Music just flows better and hence is “nicer” to listen to, vinyl and digital. The sound is not softened or less dynamic just more fluid and flowing it is easier to forget it is recorded music.
I found myself having to turn down the volume as there was an absence of any edge or grain. This is a similar sensation to first obtaining the Dart, everything was clearer and distortion free compared to the previous set up. The Yp pre, and when using vinyl the VPS, takes the listening experience to a new level.
I had the amps together for over a week. Switching back to the Dart was a disappointment, brilliant as it is. They are both very transparent machines, deconstructing the music and representing the performance through the system, it just seems the Yp pair do it in a more coherent and convincing manner.
