New Yamaha a-s3000 and a-s2100 integrated amps ??

Foster_9, I also have a a-s2000 and its good but its much better after you coat all the connection wires inside your a-s2000 with QuickSilver Gold contact enhancer.

Unhook all the connectors wires going to your Transformer and amp and pre-amp and coat the tips of the connector pins using a toothpick.

I was thinking about getting a a-s2100 before I tried this tweak to my a-s2000 but now I'm just loving how my a-s2000 is sounding and I think I will just keep my a-s2000 until the a-s2100 go on closeout in 5 or 6 years.

Back in the 80s, I had a Yamaha R-100 reciever, That was the very best sounding reciever to this day I have ever listened to, If any of you can pull it up on the internet, you would see why, The led equilizer was so profound, just one bump of each one worked very good, unlike other equilizers, Man, I miss that reciever!

For anyone that has a a-s2000 and wants to try out my QuickSilver Gold tweak, you have to be VERY CAREFUL when your pulling these connectors off with needle nose pliers because you can bind these medal pins VERY VERY EASY !!...

I bind two pins myself on my pre-amp circuit board so be VERY VERY CAREFUL when doing this tweak !!.....

It takes about 17 days for this stuff to break-in GOOD and sound its best.

My Yamaha a-s2000 now sounds like... I got it CRYO TREATED !!..

My A-S2000 began sounding better than any amp ever made in the future as soon as I aimed it north and put Bolivian coffee grounds on the shelf under it. Uncanny!!!
I tried Colombian and Ethiopian grounds without an overwhelming improvement. What is it about the Bolivian? Has anyone else tried this?

"as soon as I aimed it north and put Bolivian coffee grounds on the shelf under it."

@Macrojack. Now I know you're exaggerating. Everyone knows that it takes at least 1000 hours burn in for the amp to electromagnetically align with the Earth's poles and for the coffee beans to caffeinate the EMI & RFI signals.
