Hcalland, if your phono stage has enough gain by itself by comming out of aux and bypassing the preamps tube line output stage, then yes you are getting rid of an unnecessary tube gain stage and the result will be more transparency.
Todays sources (phono,cdp,dacs) all have enough gain by themselves to drive most amps to full output, why add another preamp gain stage, only to knock the gain of the source back down with the volume control and creating more noise.
Just read what Nelson Pass has to say about it here.
