What used speakers raraely come up for sale


Lets keep it under $7,000 used, but interested to hear what used speakers rarely get listed for sale because they are so sought after and if they do appear they get snapped up very quickly?  Cheers

Lirpa Labs is a fictitious company used as a joke since the old Audio magazine's October issues which listed almost every audio product made at the time. Maybe even before that, but I don't know.
Yea gentleman,  I fell for that one a minute, until I rationalized  the specs as being preposterous. LoL!
Pair of Silverline Bolero speakers just listed.   This is a great speaker folks. So musical and unfussy. Great with tubes or SS.   Rather easy to drive and wonderful music makers.   I have only seen two sets in the past several years.  
Its interesting to note that while many other other models have come and gone over the past 10 years Silverline is still making this model yet it rarely comes up for sale used. I've had mine for over 7 years now and they sure aren't going anywhere. One of my best audio purchases, perhaps even better that my ARC SP 10 which I kept for over 30 years. :-)
