Cossinaro, I admit that I am not familiar with the Aesthetix Rhea. But I have been around the block quite a few times with ARC gear. IMO, there is a real synergy with ARC gear which I think augurs in favor of matching an ARC phono pre with your very excellent ARC LS-27 linestage.
Therefore, while I agree in principle with what Zd and Ct posted, I think a good use of bucks would be matching a preowned PH-7 or PH-8 phono pre with your LS-27 and getting a better cartridge.
Of course, if you can get a **KILLER** deal on an ARC Ref Phono 2 SE, then that would be a hard upgrade to pass on. But Zd is right about overpaying for the Ref Phono 2 SE. If you ever wanted to switch it out, albeit unlikely, why buy something that comes with a built-in-loss.
I've done the Soundsmith Zephyr, the DV 20X2 (H), the Lyra Delos ... all good cartridges. But IMO the Lyra Kleos is really special and is very compatible with the VPI Classic 3 arm.
Bottom line: try to match an ARC phono pre with the LS-27 and put some bucks into the cartridge.
