Hello! I am selling my modded KSE1500/1200 unit. It has a Stax 5-pin plug and can be used with this accompanying Kingsound amplifier - or, if you want some really excellent performance, it can be used with a Stax desktop amp, but DO NOT USE IT WITH A PRO BIAS SOCKET! It can only be plugged into the 6-pin Normal Bias sockets found on older Stax amplifiers. It sounds incredible in that setup though, with detail retrieval comparable to the higher end Stax units, and excellent subbass due to the seal and isolation.

The included Kingsound amplifier can also be used to power it. It occasionally cuts out on one side, I'm not sure what is the cause of this but it appears to happen when the battery is low. I have not opened it up to check solder points or anything, so it could very well be a quite easy fix.

I have SpinFit CP240M tips on it which work quite well.

Shipping and fees included. Feel free to DM me any questions. Thanks for looking!
