A couple of things, yes, some compressors/air supplies for some of the air bearing tables can be quite loud. The one used for my Holbo is absolutely silent, but it is more of a lower pressure aquarium style pump, not some hulking compressor that some makes utilize. Various manufactures all use different things, and obviously as you said, tout one design over the others.
On an air bearing table, and possibly on most linear tables, I would maybe not recommend a fully suspended table. It in and of itself can be trouble with these designs-potentially. I cannot imagine setting mine up on a fully suspended table, I would probably bin the thing, or quit all together.
What brought me to the Holbo was a more overall simplistic design in general, it doesn't look like an oil rig either. Bostjan Holc of Holbo has designed a fairly simple, in relative terms, table that just does its thing without too much fuss. And he was great to deal with, answered any of my questions and delivery was smooth. Obviously not having an air bearing table before this one, I had a bit of a learning curve, and still am tweaking things in here and there. Overall though, it has been a lot of fun and the thing just works and plays great music. So do a lot of other tables though!
Other tables I had considered were the Well Tempered tables, Pear Audio, Nottingham, were main ones. I had owned an LP12 and also early Well Tempered Amadeus several years back. Loved the WT more than the Linn in general, but my curiosity with linear arms eventually got the best of me. And, I had been away from analog for some time. FWIW.
I am sure with time and effort, you will find a table that will suit you, take your time and have fun with it!
