Freezing my butt off with you buddy. Can't wait to hear it myself. I'm putting together the amp chassis over the next few Weeks. Will probably turn into months. But forward movement at least.

Well guys, I went to the dark side (NCore). Not regretting it. 0.0003% THD+N at 50 watts is not too shabby.

Hi FloridaBear,

Great stuff,
Need some education, you mean a "NCore" transformer? and this would make a difference in THD compared to say a torodial core or a regular "E" laminated core?
What test equipment are you using to measure this low value of THD?

Thanks
Rick

Not sure what FloridaBear's post has to do with The Wire. Did you build/listen/compare The Wire to the NCore?

I purchased and tried to build a pair of Wire amp boards but it proved to be beyond my meager skills. The NC400 build seemed to be the best way for me to get an ultra-low distortion amp. I was just posting as a "happy ending" to my Wire adventure.

I purchased a kit from a member, but the SMD resistor values doesn't match the shcematic from the first page. Any reason for that?
