Hi guys,Have any of you used JBL SE400S and want to share your experience?
Actually I've found a very nice one from ebay recently, and tested it with SG520 preamp.Despite the fact they're vintage gear dating from the 1960s, I hear the sound is just great.
I've been listening to jazz with this match on 4343, with pleasant experience.
This is JBL 4343B driven by SG520 and SE400S on Youtube:

One thing I find lacking is when biamped, with SE400s for mid/high and CROWN DC300II for low,the more dynamic, live sound that I used to hear from the bi-amp mode with two Crowns. At first I suspected this SE400S "Energizer" is not for bi-amp purpose. I just wonder how jazz cafe Basie in Tokyo has become such a famous place for its such live jazz sound with SE400S, preamp SG520 and Xover 5234A...
