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?
