I just assumed that you already had a linestage or passive volume control. You will need one. Depending on the gain of the phono stage, and the output of the cartridge, you may or may not need any gain from a line stage. If you get the Aesthetix IO, it is available with built-in volume controls, if phono is going to be your only source. If not, you will need some kind of preamp, whether it be active or passive, so you can do your switching and attenuation. The phono stage is a separate box that will plug right into your preamp high-level inputs. These phono stages that I mentioned are stand-alone units that will do all of the RIAA equalization and phono gain, and cartridge impedance loading. You just plug your tonearm cable into one end, and run a pair of interconnects out the other end, into a preamp input. That's it.
There are alot of good active preamp options, and you could take your pick. The passives are touchy, and I would personally only use a transformer-based type, like the ones that Bent Audio offers. They are much more impedance-friendly, and provide much better sound and easier use, than the resistive-based passives.
The other option would be to get a complete active preamp with a built-in phono stage. That would give you everything in one box. Many good ones are available. A popular one right now is the Supratek Syrah at about $2500. There is a waiting list, and about a 4 month wait. Alot of the members here have one, and many have said they liked it better than preamps costing many times more.
