Hi,
i can try to help...
1 - the require space for the actual footprint including its own arm angles etc is about 70x70cm to be clear of interruptions (i gave it a little bit more)
the height is about 83cm from floor to platter and around 6-7 cm more to the top VTA adjustment knob..
the total weight is a bit tricky because the legs are "empty" and you can choose what to fill them with, for greater stability. Pino from VYGER can suggest to get some quartz send in a plastic bags and fill the gaps to get some more weight, i did something a "bit" heavier...
but lets say its around 100(++)kg excluding the TiTAN of course.
2 - Negatives... mmm, after a lot(!) of turntables, arms, cartridges, phono stages and all that analog holy in my 40years of playing vinyl, this is the BEST TT i ever owned. (i have the top of the line Titan also and a second arm mount) and i had a lot of top game "end of the road" Turntables.
i think from some experience and conversations with Pino- a lot of owners got stumbled with it because of lack of basic (and not so basic) knowledge of accurate and good set up and that what you will need to get if owning one. but i can assure you, when this thing is proper set up (not such a problem really) and taking care of (free of dust and Humidity) with a stable floor and delicate hands, it will not break a sweat and will preform 100% perfect every time! you will not believe how vinyl can sound through it.
like ALL linear arms table systems, it need some attention to set up perfectly or it will not perform! not like a pivot arms that will 99.999 of the times play the vinyl. but not always the music..
3 - unfortunately i didn't had the XL at my possession personally but the 4P 11" I had for 2-3 years operating on several turntables and against a lot of tone arms...(i don't have it anynore, basically because i found better arms and for some specific problem i had with some specific cartridge that "Kuzma" couldn't help me with or didn't had the time... WE. i still think its one hell of a good arm!) be that as it may, i know the XL very well from a good friend of mine who has also AF3P to its side, listening to 4 arms between them including the kuzma new air linear arm...
to make this story very short, i prefer mine (a lot) better

hope that helps a bit.
