Baranyi--Not sure if anyone ever called a maplenoll a plug and play unit:>) However, i do think the maplenoll ariadne is one of the better tables out there. I currently own the white ariadne reference, grey ariadne signature, and the apollo heavily modified by Lloyd Walker.
Your first question, i changed out my air pump to a JUNAIR compressor back in 2006 and have not looked back. The compressor is one used a lot in the medical/dental field so is pretty quiet, reliable, and clean smelling (not always the case with the original pumps). If you look on this string you will see MEDO and WISA pumps also mentioned. I like the Junair because it has a rather large surge tank and great pressure control regulator that matches well with my air system. Clean, pulse free air at a pressure your arm likes is key to keeping these machines happy. The Junair uses a synthetic oil that is odorless and does not bleed off very much even with heavy use.
Concerning oil trough, i find it is a very good tool to get the utmost out of the system. it tends to solidify the bass in my opinion. I personally do not like the tonearms that came with the maplenoll and have modified both the ariadne to carbon fiber arms and relocated the oil bath to directly below the air spindle using a tapered pen similar to current walker tables. This way, the mess of the oil trough is eliminated. Its a little complicated to do this modification but i get a maplenoll with on the fly VTA adjustment, better dampening of the arm, and a stiffer assembly with the carbon fiber arm and headshell. There is a difference with using the oil trough versus not.
Hope this helps
