You can only keep one pair of speakers on the list


SO, I have been told that my small collection of gear needs to go and I can only keep one pair of speakers. I will have the chance to build my collection again but for now I only get to keep ONE pair. SO, here you go guys, I would like to hear ALL of your opinions and why.
Lets forget about what I will be powering them with and so on and just hear about what you would keep if you could only keep one pair. They are all in great shape.

1. Phase Technology PC-1000
2. Polk SDA2b
3. Teledyne Acoustic Research AR9ls (with i mod)
4. Mirage 1295is

So how the heck to I make a choice between the AR9ls and the SDA2? Both of them have a unique sound, and I like them both in different ways. My thoughts are that I should be able to replace the sda2 for less money that the AR right? What are my 9ls speakers worth?
selling big speakers aways comes back to condition and original boxes, etc. both pairs could fetch higher than blue book, if they're cherry/near mint.
Does anyone know about the AR TSW510 speakers? There is a pair near me for 75 bucks but they would need to be refoamed on all drivers.... Worth it? Specs? Thanks
Upgrade the 2B's to TL status, sell everything else and you'll never look back.
