Best Amp and Pre-amp with silver transformers and silver wiring


Recently had a chance to listen to Audio Technica AT1000T with Ikeda Kai cartridge in my set up. Was blown away!! 
I read that it has silver transformers.
Would like to hear what was the best Amp and Pre-amp with silver transformers that you heard and compared with what. Also, please list other components in the system.

Thanks!!

I own a very nice amp with silver wire output transformers--Audio Note Kageki.  But, I cannot say that it is necessarily the transformer wire composition that makes it a very good amp.  I also own a pushpull amp with copper wiring that I actually prefer to the Kageki (a custom made clone of a Western Electric 133).  The two best amps I've heard did not have silver transformers; one is the Western Electric 59a, and the other is a custom-made OTL amp that doesn't have output transformers.

I don't think that any particular design feature is the be-all and end-all of amplifier design.  
@mijostyn can you pls share which were the best amps you have had? Have you compared with any amps with silver transformers?
Thanks
