"Too much gain"? (Cary SLP05 question)


A few days or so ago, someone had revived an old Cary SLP 05 thread, and common to that discussion seemed to be the subject of too much gain. 

My first question is:  does compensating for too much gain by simply adjusting the volume knob knob down degrade the sonic quality?

My second (2 part) question relates to this quote from one of the replies in that thread:

 A quick note to Pass Labs and they suggested a pair of Rothwell 10db balanced attenuators into the amp’s inputs.

What exactly do balanced attenuators do to resolve this issue, and if placed between the preamp and the amp, would they degrade the signal path & therefore the sonic result out of the speakers?

I am a relatively new owner/operator of a SLP05 and it is in front of one of the earlier Cary V12s.  I did find those balanced attenuators on ebay for (I think I remember them being) $89 a pair, which I find totally doable.  I am lsitening in a (very) near field room right now, and it seem as if I do have a lot of gain.  Generally the big knob is on 9 o'clock plus or minus a little bit depending upon the source material I am listening to.  I am using the balanced ins and outs to & from my SLP05 and I have been given to understand that using RCAs would reduce the gain somewhat.  I do have some RCAs (I am presently using Kimber Silver Streak balanced interconnects) but my collection of spare RCAs is Kimber PBJ and Monsters. 

For $89 should I try putting a pair of those  of Rothwell 10db balanced attenuators into the balanced amp’s inputs?

"After reading through that revived SLP05 thread, it made me wonder and inquire if the same volume would sound better if I was obtaining it at a higher setting of the volume knob.  In other words, would my desired volume have a better sonic quality if it was achieved with the volume knob set to twelve o-clock or more as opposed to  nine o-clock."

 

 The answer is likely no. By adding the attenuators you're adding another step in the signal chain. Most of us would agree that is a bad thing. Just paint a new indicator on the volume knob. 

The reason for having a volume knob in it's "sweet spot" is that's attenuating, or altering, the signal the least possible.  By adding in-line attenuators you're working counter to this.
