I need a loudness switch

I am by no means what I would consider a Audiophile, or a Engineer. 
 But I am fortunate enough to own some semi decent equipment.  I love music that gives me goosebumps. 
My CD playback is fine , as I don't really use it anyway. 
 But as with many others I lose substance at low volume with vinyl playback.
Dial set between 55 and 60 things come alive. But that is too loud for most sessions. 
 System is.
 VPI Classic table with a Soundsmith Carmen mkii cart.
Decware zp3 phono stage. 
Conrad Johnson et3 preamp
Conrad Johnson premier 140 amp.
 Proac Response D38 speakers.
 I would love to run the system around 35 to 45 setting , but to have a little authority. 
Does anyone have any suggestions?
 I was considering a Decware zbox that boosts the voltage. 
But with not being a Engineer.  I do not know what effects the 4 volt input will have on the cj gear.
Any input would be appreciated.  
Thank you,  Scott

mijostyn: Yes, I’m aware that old loudness controls boosted both bass & treble, and that the F-M curves justify that.

I read many years ago that the treble boost is questionable. I can’t remember where I read that, so I can’t cite a source. I will say, my subjective experience is that boosting the bass provides most of the benefit. My preamp has a treble control, & I’ve never felt the need to boost treble as volume decreases.

Mike, if you look at the Fletcher Munson curves the boost in treble is pretty high up and is less noticeable than the bass boost which is in a part of the range that is very obvious. So you are right in that the obvious part of loudness correction is in the bass but if you could AB curves you would note that the curve with the treble boosted correctly sounded more natural.

You have to love Amazon. 
 1 day shipping and I am trying out the Loki.
 First impression as I listen to my first lp.
Yeah, I think this will work just fine.
 It is subtle but effective. 
 Not hyped and overblown.
 I will see how this goes.
 Thank you to those who had input.

I have been listening with the Loki for 2 days and I am completely impressed with it.
 I can now listen at the 3 o'clock position and get full sound.
 So satisfied and thanks to those that suggested it.

Funny how some time with a piece will really change your mind. 
 I yanked that Loki out.
It really does get in the way of the music. 
It was neat at first ramping up the bass. 
But it got old after about a week. 
 Thanks for the suggestions. 
Lowering the vta actually fixed most of the thin sound.
