If you have low input impedance poweramp <50kohm. And you would like to use Lightspeed Attenuator with it. It would be good to have a buffer after it. Here are 2 different very good value stereo buffers to use, one even has the power supply built in.
I had a customer use the simpler cheaper one and he said it was way better than any of the better opamp buffers he has tried and used.
It would be nice if someone could sim these to see what they like in a non real world.
STEREO FET BUFFER FOR DAC, PREAMPLIFIER, TAPE REC, ... (eBay item 380285512821 end time 03-Jul-11 00:09:41 AEST) : Business Industrial
STEREO NE5532 + DIAMOND BUFFER LINE LEVEL AMPLIFIER! (eBay item 150485089508 end time 22-Jul-11 13:56:55 AEST) : Consumer Electronics
