"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?

@testrun , I am not attempting to be sarcastic, but if all you are using the remote for is the preamp, how could it get much simpler?  I mean it has an up or down for the main volume knob and that's all that applies to the preamp.

The SLP-05 using balanced outs to the Bryston at 23db gain should work out well, no upgrade needed.  

I use the L-R pots at about 60% or so, just to trim a bit for L-R balance.  

@testrun    My preamp is made by a boutique manufacturer - which also has a bulky remote control.  I only use the volume buttons.   I replaced it with this slim universal learning remote control. It learns the code by pointing the two remotes at each other - as per the instructions.   I liked it so much that I bought a few more for my TV and HT receiver.   They’ve been working flawlessly for over 6 years.  Just replace the AAA batteries once a year.   Since the price is so cheap, the tariffs shouldn’t be an issue.

This replacement is for infrared remotes.  Not Bluetooth remotes.

one more thing related to the SLP 05 gain settings- speaker efficiency.  with my 90db Spendor towers they sound best with the RCA lower output connections into my 29 db McIntosh amp.  

with my less sensitive Dynaudio towers they sound best with the full gain using the balanced connections.
