Speaking of Pioneer CS-series value, their TOTL brother CS-99A sold today $760 + $120 shipping = $880.

And this pair (not mine) is not even mint. From seller description:
Walnut veneer that has some wear from time which is normal. There are some water spots, paint specks, and scratches. Dings to edges, corners.
How much would be for CS-99A in true close-to-Mint condition? With good description and close-up pictures, my guess is above $1,000, believe it or not.
