MOTM

Does anyone have a recommendation for sourcing dual log pots of MOTM 
quality for use as audio input attenuators? I searched the archives and 
this was addressed, but several years ago and without a "final answer".

I know Bourns lists dual-ganged audio taper in the MOTM flavor (91A2) 
but I've only been able to find them up to 10K ohms (at Newark). I'm 
just a software guy but good practice seems to be to use 25K - 100K ohm 
pots for audio inputs.

I got a couple of the Bourns 10K duals anyway. Can I use them directly 
at the input to an amplifier for line-level stereo signals, or do I 
need to put some kind of buffers in front of them for higher input 
impedance? Or use cheaper pots in a more appropriate value? (These are 
for external inputs to my synth, so the output from any random piece of 
audio equipment might be plugged into them.)

Thanks,
