Kondo Audio Note Io ii+ Kondo AN S 7 II - Keep it or sell it?


Things simply keep accumulating. At the moment I have both these pieces lying around in a drawer. I am in a quandary, because it is simply a shame that they are not being used. I assume that they will not depreciate in price, but what are the chances that they will appreciate?  

To put it in other words: Do I try to sell them now, or do I leave them in the drawer?

Thank you. I will mount the cartridge and try it out again before I decide, but you certainly have given me food for thought.
I'd sell it. The AN S 7 II was surpassed by the KSL-SFz, which I owned both. I just sold 2 of my KSL-SFz step-ups for a superior sounding SUT out of Russia.

Well, they are pretty rare, and prices are all over the place. That is part of the problem, there simply isn`t much information on the internet. 
As you say, probably quite desirable as a pair. The question is if they will appreciate in price and are best left in the drawer, or will the cartridge be better off being used.
Definitely collectible! And very desirable as a pair! Price? Needs some researching!
No. The Io ii is an old Japanese-made Kondo cartridge from the early eighties, and the S 7 is the matching SUT. I dont know how collectible these are, which is why I started this thread.
