Sorry I can't remember (or find) the colleague who recommended these.
I have tried one in my Pioneer sub (admittedly on 458 Mhz where noise and glitches are generally no problem) on several occasions and it works fine. It may have changed my generally negative view of noise from switch mode power supplies. (I have ordered another couple.)
