I've had excellent luck in the past with run-of-the-mill pots that were anything but boutique. I would suggest that you start with something inexpensive, maybe even Alpha, but leave plenty of space around it for an upgrade if you find it lacking for some reason. Also, many of the stepped pots on the market don't have enough positions for good adjustment (24 steps isn't enough). There have been a number of reports of failures with Khozmo pots. PEC pots (Precision Electronics Corporation) and TT Electronics are very good, but difficult to find in the values we usually need.

Re Khozmo failures - I had one, though an older model. They're slow on emails too. Sounded good when it worked.

My cheap solution is a 100K log plastic pot with 12K series resistor and 24K across the 100K. With top quality resistors it sounds very good. Only 4 resistors needed.

  What is the purpose of the resister in series and the resister across?

    The series resistor is fixed in a shunt volume control. You can look up ratios for the series and shunt resistances and you'll get a variety of answers. My ballpark is a bit under 1:2. A 100K pot is a good start and then I used 12K and 24K for series and shunt. Seems to work as a volume control. The quality is in the resistors for which you can go as boutique as you like since there's only 4 of them. I didn't want to go above 12K as a series resistor and the rest followed from that. It actually sounds pretty good with the NOS resistors I use. I'd say as good as or better than a basic TDK.
