Why so many ARC Ref 6SE preamps up for sale?

As of 10:06 AM EST today, there's not a single ARC Ref 6SE for sale on A'gon.

Why do people feel the need to ask why “insert component” is for sale?  Things come and go.

This might be slightly off topic, but can anyone confirm what kind of volume control module/mechanism the REF6SE has?

Over the past two months there were like 7 Ref 6es listed internationally and none in the US. What the hell are you even talking about? You’ve apparently been here about 23 years and started six threads, and THIS is where you wanna go???  What’s your agenda here?
