Thought I would try the easy to do mod of soldering in a couple of 270K resistors inline with the RCA inputs as per Pauls suggested mod in the Crack FAQ section. Using a Vishay 270K, 5%, 0.25W Metal Film and it works a treat.
Resulted in a feeling of having improved range and finer user control of the volume levels it also removed a very slight channel imbalance which was noticeable at the lowest level.
Thanks Paul
Jamie.

I am considering doing this, but I think I am going to wait and see what the BH Dac outputs. I'm currently using a Music Streamer II and with iTunes at full volume I'm limited to the first 1/4 turn of the attenuator. I haven't noticed any channel imbalance with my control. I've read that turning the iTunes volume control down decreases the bit depth but I don't know if that is actually true. I'm more inclined toward a "mechanical" solution like the resistors.

I also have one of the Valab 23 Step Attenuators on its way and am planning to take out the resistors when I fit it, swapping them back in if needed as it only takes a couple of minutes to do so.
