Interested in trade for Yuin OK1 or Minibox-E+, Grado RS1 + cash difference.

Amp is very clean, works like new and sounds exceptional. I am the 2nd owner, bought it 4 months ago when it had 100 hrs of burn-in and usage. iQube's warranty is limited to original purchaser only. I have feedback here and Ebay under the same username. If you have any questions, feel free to PM me. I ship same day or next day. Additional Shipping for International.



iQube $old

With the iQube you will get
- USB charging cable
- 1 unused iQube band, 1 used iQube band,
- mini to mini cable
- rechargeable batteries already installed inside.
- retail box
- user manual
