[QUOTE="handsome, post: 1079002, member: 772"] Use a potentiometer of no more than 10k - worst case output impedance is 0.25x pot impedance. So 2k5 for a 10k pot. 1k25 (better) for a 5k pot. Be sure your source can drive pot impedance thats no issue for any modern solids state devices - not so good for valve equipment with a 10k pot. Ideally the passive pot should be cloder the the power amp than the source (source has a low impedance output). [/QUOTE]
