Well, after the thunderstorm ended, I fired my Yamaha RX-V 2220 back on, and I can officially say that the amp section is dead. non of my speakers work, and I mean, not even a faint background noise, I have no sound at all.
I bought it in Yamy in 2002, so it's been obsolete for a while. The timing couldn't be worst though. Having just bought my GH-1, I certainly hadn't planed on buying a new surround reciever.
On a more positive note. My vintage Marantz 2226B, hasn't been damaged by the storm, so I was able to get one more hour with my GH-1. In my opinion, Grado has achieved a near perfect balance with the GH-1, meaning that neither the bass, mids of highs stand out above the others.
I have found that I have a very hard time taking off the GH-1. I think that their softer treble, and forgiving nature, is probably the reason why. Anyway, it's all good.
