Purifi v Gan amps?

Gan transistors we’re invented many years ago , they are much more efficient

and will be in.many more products. In the future ,they are very good I actually own a GAN charger for my phones and tablets ,over 3x faster ,

My point is ,I have seen several amplifiers advertising gan transistors which is good 

but the rest of the guts were average at best , that was my point .very good value for a lower mid fi  amp.by Audiophile standards and todays pricing.

Don’t get sucked into buying just because it has GAN in its build , if these were the end all most other top companies would be using them ?

i have a top Coda integrated it’s not in Thst , Pass labs, AR , Boulder, Gryphon ,Goldman or many other top companies , there is so much more to the engineering 

and build quality , please keep this in mind it’s all about Marketing, being in Audio for decades I remember when Technics said look at these new great amplifiers 

vacuum tubes are dead they can’t compete in measurements yet they are still going strong, track record,and reliability count most !!
