Anyone here using vintage speakers?

I have a pair of 1970's Sansui sp-2700's.
These are VERY good sounding and very cool looking speakers.
These are the most neutral and best sounding speakers I have ever owned.
I noticed no one mentioned the Sansui sp line of speakers.
Has anyone owned the sp-2500's or sp-2700's and care to comment on these speakers?
I know the sp-2500's have a efficiency rating of 98 dB 8 ohms.
Does anyone know the rating for the sp-2700's? I cant find the info. anywhere.
These speakers have to be the best buy in audio.
Lots of Sansui sp series speakers on eBay that usually go for $200-$300 shipped.
I bought my absolutely mint pair for sp-2700's from a local on craislist.
The speakers 'and' a mint Sansui 333 receiver (mid fi) cost me $40.
I also have a near perfect pair of Dynaco A-25's I bought for $6/pair at a thrift shop.

Ess amt 1b-amazing-will put many high-ends to shame.

22 year old JBL 250Ti's, with a few mods, still pleasing.

I have a 1974 sansui sp-5500's the best that sansui ever made period! One of the best sounding speakers eer made!

I have Leslie DVX15’s hooked up in my second system right now, and late 70’s Obelisks in my bedroom. I also have EPI 350’s, DA D8’s and D12’s and Innotech D24’s that I also use occasionally. I have quite a few others as well, but these are the ones that I have used recently.
