A few days ago I got a some of the XSM series transformers namely the XSM10K/600, XSM10K/10K and XSM2.4K/600 (custom order).
The 10K/10K's step response is as good as it gets and it is paired with good bandwidth. Both the 10K/600 and the 2.4K/600 had pretty good step response, but the 2.4K/600 has less of an overshoot when terminated with 600 ohms on the secondary. I got the 2.4K/600 transformers to be driven by an ECC99 based SRPP output stage (under development, oh, for months...)
The bandwidth is sufficient on the step down units and the singal is not visibly attenuated until 80KHz. I realize that none of this is accurate data resulting from thoughtful measurements, but this is all I had time for.
At $12 these are REALLY a bargain.
