Nahash5150 10,433 Posted February 19, 2024 Posted February 19, 2024 After servicing quite a few Sunfires, I've noticed their shortcomings as well as areas which can be improved. I am currently working on a relatively universal upgrade for Sunfire AMPs. The upgrade will include updates to the amplifier circuits and tracking down converter for more power, better durability and much better soundstage. 4 3 1

It's looking like the mkII mod will be an extra $500.
Noldk 2 Posted November 14, 2024 Posted November 14, 2024 I would be interested in getting more information about this upgrade in particular for the Sunfire Signature Stereo II Amp. Additionally, I have a Sunfire Theater Grand IV that has decided to output a nasty hum in all settings, thoughts on repairs? Thank you in advance for your feedback and assistance. v/r Kurtis Nold
