Are the Aesthetix Rhea as popular as years back ?

I have had mine for two years and absolutely love it. I listened to the ARC PH7 and the BAT VK-P10 and preferred the Aesthetix Rhea to all other phono stages that I tried in my system. The ARC and the BAT were great, but for the sound, price, and flexibility the Rhea is though to beat.

Has anyone upgraded to the Rhea Signature?

I have a Rhea with reference mods done by Steve Huntley at Great Northern Sound. I am quite pleased with the exception of noise. With that said I am not looking to replace it. I have not heard a stock Rhea or the Sig model that Aethetix offers. Does anyone have a suggestion for a line stage that really compliments the Rhea??
