Is a $100 XA capable of "audiophile" sound? Absolutely.
Is it possible a table worth a $1000 is 10X better? Probably not.
Every table worth its salt endeavors to isolate unwanted resonances in order to allow its cartridge (mounted at the end of its tonearm) the ability to extract the maximum amount of information from a microsopic record groove as accurately as possible.
I personally believe the XA was the first TT design to excel at that task of isolation and extraction. However, I would be foolhardy to think that tables and arms since the XA haven't advanced that design. In the 1000 dollar range, is that improvement tenfold? In my opinion, no. Still, my vinyl playback addiction is certainly motivated by the desire to attain that sonic nirvana where the background noise is dissipated ("blackened") and the extraction of music is elevated. To that end, spending a $1000 or more on a table is worth it if you can afford it, and the rest of your equipment can reveal that improvement.
Could I live happily ever after with an XA? Absolutely. It's a table that greatly exceeds the sum of its parts. However, because I have been lucky enough in my life to be able to afford some more expensive tables, I have been able to experience improved levels of what the designers of the XA set out to do.
I hope this helps.
