Tone controls? Sorry about the heresy.

I will not live without remote volume and remote balance control from my listening chair. I also like automatic Fletcher Munson EQ for low volume listening (misnamed ’loudness’ (essentially low volume bass boost) if properly implemented.

This Chase Remote Line Controller has that as well as remote tone controls, mute, input switching.

this one is sold but has all the info

’absolutely no noise or distortion, Signal to Noise 105 db’ is true, no one can tell if it is in or out of my system. I use 2, and have a spare, I’m not living without one.

a slight balance tweak can make a surprising difference to some tracks.

they pop up for sale occasionally

The Schiit Loki EQ didn't exist 11 years ago when this thread was started, but it does now and it's an amazing little thing...I use mine sparingly but when needed it does the job perfectly. A no noise little gem, and at a silly price.

+1 for this, it’s all you need
Here's what it can do, and it's very transparent.

Nice unit, it is a silly price, I would add balance, and remote control, and mute to take a phone call.

I have two of these, absolutely love them, and the third system has a Luxman pre with tone controls on the remote.  Tone controls of some sort are a necessity; not always needed, but when they are, they are wonderful.
