If you like the warmer sound of the BB's you can get a nice tube like sound from AD797's. For still better sound, and unlike most AD stuff you have the AD8066, perhaps the most perfect sounding opamp ever. This little dickens can cause you problems though as it is only SM, and as it is a low voltage design.

To use them in higher voltage circuits DIP circuits you need to put opens between pins 4 and 8 on your Brown Dog adaptors, and pins 4 and 8 on your AD8066's. Then you have to toss in some resistors, 330 ohms is a good starting point. That will keep the AD8066's from running hot and ultimately burning up. If they sound bad but are cool, go to a 220 ohm resistor between pins 4 & 8 of your Brown Dogs, if they feel hot go to say a 470 ohm resistor. You can do the same on your CDP's circuit board, but it's not pretty...
