Your budget is $1,500, yet now you’re looking at a $12,000 piece just because a few Audiogon users said so. An $8,000 used price is not a deal—$5,950 might be, but it’s still four times your budget (and the seller might even be behind the scenes).
In the $6,000 range, there are many strong options that have received solid professional reviews. Have you done your homework? Why a piece sitting for ~5 months at a steep “marked down from $12k to $6k” price can not get sold in 5 months? Thank about it.
