What speakers have you mistakenly let go and then later repurchased?

Audio Physic Scorpio,not the greatest speakers but they did everything well. I've had many speakers since (Acoustic Zen Adagio,Scorpio II,Audio Physic Avanti III & Canton Reference Jubilee) but they all lacked in some area compared to the Scorpios and I was only driving those with a Sunfire receiver at the time

Well I never repurchased a set of speakers but I should have kept the Acoustat 2+2s, for my living room (secondary listening room) from 35 years ago.  Sold them very cheap.

@fredapplegate I get your point but my new wife hated them because they lacked bass punch/depth, extremely beamy, a bright overall balance and limited dynamics.   This in a 540 sq. ft. room.  This was 25 years ago.  I replaced them with dynamic speakers and she was ecstatic over the choice.

if you haven't owned any of those twice, it doesn't apply here.

Purchased B&W (Bowers & Wilkins) 802 Nautilus in 2000.  Because I was downsizing and thinking they were ill fitting the new abode, I sold in 2015.  What a ludicrous mistake.  Tried out 803 Nautilus and 804 Nautilus to fit the new room, and not as good sounding.  So found a pair of 802 Nautilus this year and problem solved.
