Something you might be interested in that I saw on the CJ website regarding P120’s:
1. All versions are superb, the deciding factor lies in the user's personal preference of output tubes.
2. The EL34 sound is magical, it has that enveloping sound, wraps around you and you can melt in your seat...
The mid-range and musicality is superb, plus the 3D affect on the mid-range one can reach out and touch something...
3. The SE version fitted with KT120's is all of the above at a very powerful level. It will produce a heavy slam on bass when called for and lift the entire soundstage to a remarkable level of resolution and depth. At the same time it is fast and quick to respond and can handle higher peaks driving virtually any load (even electrostats) at very realistic levels. It will not over-power or be overbearing in any terms.
4. My overall preference was the EL34 version fitted on the SE, that was something special. Similarly to the ARTsa fitted with EL34's, as for me it had that "classic CJ sound".
5. The KT120's are more powerful and provide an effortless sense of drive and dynamics along with superb transient control.
All versions are extremely musical, therefore tubes is a personal choice and would have to be personally auditioned to finalize.
