Parasound's Hint 6's new volume control provides huge sonic advances?

IF you have a very high end and very revealing system, then you will want to consider this, it would be overkill in many systems.

Regarding perfect balance, I have and use remote balance, from my listening position, as I find many recordings are a bit off, a slight tweak can make a surprisingly big difference regarding both imaging and 'opening up' the music, individual instruments properly distinct from others, an improved level of involvement.

I have 3 options for volume: manual vintage tube preamp; remote line controller (rlc) with remote volume and remote balance; remote volume of modern tube integrated amp (no balance). I use the rlc, preamp and amp preset at half volume.

Simple signal path, minimum cables .... I try/listen of options: source direct to amp, thru preamp to amp, direct to rlc then to amp, to preamp to rlc to amp. I find signal to noise the important criteria, my rlc has s/n 120db, no one can tell if it is in or out.

You have to understand that attenuation diferences between chanels will result in phase shift which will muck up imaging

It’s a good question. I do not have difficulty imagining that some devices attenuate signals more accurately than others and perhaps with less noise but how or why....who knows?

Thanks for the answers so far. I realize that attenuation must be done correctly, but I thought that would just be standard operating procedure for any amp costing $3k. The fact that Parasound is singling out this element of their design for special attention suggests that others don’t do it well enough or that Parasound  has now done it so well (compared to others) that it’s going to make a noticeable difference. I find either explanation to be pretty weak, and so there’s one more possibility, namely that their marketing people decided to tout an otherwise standard feature just to grab people’s attention. Not the kind of company I thought they were, and that's why I'm curious.

They are not the first to tout higher quality volume controls. Maybe it’s an improvement for their products. Don’t know.

I can vouch for the fact as likely could many that potentiometers in volume controls need to be kept clean else audible deterioration of the sound occurs so clearly volume controls matter.
