Up for sale is my Yuin OK1. Good as new. I have been using it for a year after replacing my Yuin PK1. My J3 drives it very well. The sound that comes out of it with my chosen equalizer setting sounds excellent - airy, clear and full of impact. I still have to look for the original box and accessories but I could remember I still have it.
I am actually just trying my luck here. I still have to decide what I would do with the money. Definitely, I'll be needing a replacement. I'm currently eyeing on GR07 but might use the money instead to finance some personal expenses. Me and my wife are having a baby soon so I need to save for it also.
PM me anytime if you're interested. Thank you for looking.
