Your single most significant purchase mistake?

Biggest mistake was dealing with Mike Powell   Bought a pair of AGD Tempo GAN amps and just didn’t work out in my system. Sent them back within 3 weeks of the 30 day trial and he said he spent my money. He pieced me back the 9k over a 10 week period while calling me names, and dogging my system. 
The dude is just the worse dealer by far I have ever dealt with….stay away

benzman,

Wow, what a nightmare. AGD should take away his dealership.

They did. Alberto told me they took it away because of Powell’s lack of customer service. 
 

That's good to hear.

i noticed the recently initiated thread on this mike powell fellow and his youtube posts were abruptly taken down... i had posted details of my unacceptable experience on that thread dealing with him
