Premium Audio Mini GaN 5 amplifier mods
This new $800 GaN based class D amp is a cute small but power packed super value product.  We do a mod to it that makes it sound mucho better.  We change the output connectors to nextgen WBTs and use seriouly great wire on the speaker output and in the power supply, etc.  This mod is $300 plus return shipping.  This amp sounds really good.
The WBT Nextgens are way bigger (and better sounding) than the stock mini posts (with steel solder tabs).   Serious drilling in the steel chassis is required.  
Well worth the effort.
