Phonostage w/volume options

I could use some opinions. I currently own an Art Audio Vinyl One with volume and Art Audio Jota Monoblocks. The combo sounds very good but I never had an opprtunity to hear any other phonostages in a similar configuration. I definately want to stick with a volume pot since 95% of my listening is vinyl. Should I put more weight behind synergy since the Vinyl One and Jota's are both from Art Audio? Or would, for example, a Steelhead raise the bar? Or an Aesthetix IO? Probably, but how about the cost/ratio? What other phonostages have volume? Should I leave well enough alone? Thanks.
