Raven Stereo Tube Amplifier Customer Service

I just wanted to send out a real scenario as it relates to the value of buying great integrated stereo tube amplifiers like the Raven Nighthawk. While there are tons of positive reviews and comments made on this forum about Raven's stereo tube amplifiers, there isn't that much said about their customer service. Case in point, I accidently misaligned a power tube and realized quickly that something was wrong (loud buzzing noise from right channel speaker). After turning the power off, I realigned all power tubes and the buzzing stopped. Concerned, I called James Connell (President of Raven Audio) the next morning and told him my problem. He told me he would send me a shipping label and to return the integrated amp and he would not only have his audio engineer check it out completely but that he would fix it for free! During our discussions he informed me there was an upgrade program for my nighthawk and that he could upgrade it while it was in the shop and return it back to me within a week or so. Now that's what I call outstanding customer service. Granted, you can buy excellent stereo components from around the world, but there is something said for really good customer service from a product made in the US.
