With all the amazing equipment you have 427, and yet, you're such a sucker for these interesting Sansuis.
Dear god, I'm the same way. I had a pair of SP2500 Sansuis. Look like they were bought, and never once played or moved. I gave them to my sister, whose son wasn't content to push the dust caps in.....he also ripped out the cones, and knifed the wood. Yeah. They're sitting somewhere now, gathering mold and dust. Ruined.
I am still seething about this, 5 years down the road.
Keep rocking them bad boys! (and I'm still on the hunt for those little Sony's you have praised).
