Volume Control Too Sensitive

My latest issue:

As some of you may be aware I have a Bryston BP-26 preamp connected to a pair of Classe CAM-200 monoblock amps.

My issue is that I have very little range on my volume knob. If looked at as a clockface, I can only go from 6 to 7 using XLR cables, and 6 to 8 using RCA cables.

Not only is this lack of range annoying using the remote control, but I question if the sound is compromised by the fact that I’m just using such a small portion of the volume knob.

Any thoughts on this?

I have the same problem, use a Roth 10 rca attenuation,

works ok.

You can put 10 or 20 db fixed in-line attenuators between your pre-amp and amp. Roth manufactures them - minimal, if an sonic down side.

This will do the trick or you can have the pre-amp manufacturer lower the gain but it's the same thing.

Save some money get Harrison Labs Attenuators from Parts Express. I used them when I had a volume problem w/a Audio Research preamp. Excellent product. They’re about 1/3 of the price as the Rothwell's and just as good.

I have a pair of Rothwell In-Line -10 db Attenuators that I previously used between a pre-amp and an amp for that exact issue. Not being used. Just sayin'...

adding attenuation beyond a volume control (attenuator) so you can attenuate less before the added attenuator. 

are you all nuts?

I would add volume controls to my mono blocks. that solves several things

1. find a level on the amps that works with a level on the preamps that makes you and your remote happy.

2, now you can use any line level signal straight into the amps. 

3. any balance issue can be solved by adjusting the amps individually.
