Was a long time Spectral Audio devotee. Had dmc 12 an amazing value and outstanding phono module. At the time both models of spectral did not have remote controls based on the sound degradation pathway. Eventually moved to the dmc 30 with remote control. Essentially the same spectral sound . Found most of the spectral equipment had thei house sound, the only reason I upgraded power amps was power hungry Maggie’s/ so answer is well designed circuit will not degrade sound
Does remote control degrade the sound of tube preamps?
Some preamp manufactures (e.g. CAT) don’t put remote controls in their preamps due to the supposed sound degradation. This could also be just an excuse. Do you think the sound quality is degraded with a remote? I am talking about an audible effect.
