This is running through an EL34 PP amp and integrated tube preamp through into my mishmash of drivers. Can't wait to change the opamp but gonna leave the blackgate burn in for another week or two just to see if it develops any problems like a few have mentioned. |

It's meant to work with low voltages(like the +/- 2.5V supplied to them from the card) and it has a max current output of 60mA with much better slew rate,THD,distortion,lower crosstalk. I have replaced the stocks with AD8620s for your information. |

Without coupling caps I get distortion when I drive XFi volume higher than 50-60%. With coupling caps theres no distortion at any volume. I'm now using 2 coupling caps instead of 4, 10uF each, seems to be enough. Notice they are parallel not serial so to use 2 the remaining 2 arent shorted but taken out the circuit. |
