I don't know your Vlad, seems a great person to know.
I thought you were talking about Vlad in Canada, I bought a few things, excellent experience, superior packaging.
Shout out for Vlad @ Audio Mirror
I purchased a pair of earlier AM monoblocks using the 6AS7 output tubes. I wanted the input sensitivity tweaked so I had the seller send them directly to Vlad. Not only did he do this for free but he also upgraded the chokes and some caps in the power supply for free. He only charged me for a couple of bias resistors and the shipping. This is outstanding customer service IMHO. So, shout out to Vlad for being one of the good guys.
