Audio Research SP16 annoying volume control


I have recently added a Audio Research SP16, the most annoying thing is the volume control.
The volume steps are not well calibrated and is either too quiet or too loud, there's not subtle ajustments, the volume just jumps to loud.
I have heard great things about Audio Research but I never expected this sort of design flaw on such an expensive piece of equipment. I am not happy at all.
Any other SP16 owners have this problem?

My dad had the 16 then jumped a few steps and bought the Ref3, with efficient speakers it was an issue but was tamed by attenuators that shaved 9db off signal, some are a sonic compromise and some get pricey but have little to no negative affect..........Rothwell makes a model some like and some avoid but they are not pricey to try.
PS The Ref3 has a volume NOTHING like the 16,,,,,,,for $10K it better not!
Mating a preamp with an amp, you need to consider several things, such as gain of preamp, gain of amp, amp sensitivity, preamp output impedance, amp input impedance.

What Audiophile have said is very true (maybe with the exception of in/out impedances). I would also throw in a mix sensitivity of your speakers and output voltage of your CD player (I had this problem several years ago when I was using Theta Gen Va which had a generous, 6V output voltage).

To remedy the situation, you can (in general) do one of the following:

1. Reduce the output voltage of your CDP
2. Reduce gain of your preamp
3. Reduce gain of your amp
4. Reduce the sensitivity of your speakers

Reducing gain of your preamp seems to be the easiest thing to do (for example reducing sensitivity of your speakers would basicly mean that you would have to buy different speakers).
So if I match the pre-amp to a ARC power, then I presume that this would fix the problem?
Matching to an ARC amp will not necessarily fix the "problem". You either need to step down the output from the high level sources as I indicated above or buy one of their newer preamps, such as the SP17, LS17 or LS26 which have more steps (nearly double) in their volume control settings. Of course you could choose to leave things as they are and enjoy the music albeit without the ability to adjust the volume exactly as you like.
Or consider something like the Rothwell attenuators. Might be your cheapest solution. I haven't tried them, but heard good things about them. Search the discussions for Rothwell Attenuators. They might do the trick.
