Hi Rsrex,
hey, he asked why not, and I told him. Probably the people who bought em then would now, and those that didn't wouldn't. Even with upgrades, most tables would still have their "house" sound. Look at Linn, Michell, others...
If a horse changed its stripes, then it's a different animal all together, and then it might be worth revisiting.
Otherwise, I say a sota is a sota is a sota...and I'm quite happy, thrilled even, for those that like them. He asked why most people don't consider them and that's what I addressed. and it's only my lowly opinion...and a maybe a few others...
Take care, enjoy your table whatever it may be!
