Does remote control degrade the sound of tube preamps?

I have Coincident Statement linestage, dual manual transformer volume control. They offered stereo volume control via remote for a short period, inferior sound quality vs dual mono. In some cases, this linestage being one, fully balanced, even to extent of volume controls, any blending of two channels will negatively affect sound quality. With total mono even through volume control sound staging is more precise, and center images are absolutely locked in, stable. MkII with even better volume transformers and my added Amtrans selector switches, extreme precision  switches only add to this precision.

Bottom line, volume controls come in many varieties, remote may or may not impact performance. IME any balanced pre using stereo volume control is compromised to some extent.

Some have a motorised control, they manually moves the knobs.
So there is not obvious compromise in that style.

@holmz I get that. In my admittedly rare case with dual mono volume selectors one would have to rig up gear system to synchronize selectors, and then you'd lose ability to alter individual selectors.

My other argument would be that stacked stereo attenuators may be inferior design to two mono attenuators. I'm thinking in terms of crosstalk, separation. Not the remote per se that makes it inferior, rather solely design of attenuators.
