Raven Audio Nighthawk

James and Bryant will take care of you.

Call Bryant and tell him what is going on. James, Dave and Bryant are all owners and they are good folks. 
I only have their cables but have talked and visited with them.

Yes. I’ve talked and emailed with James a few times He was going to help with troubleshooting I haven’t heard back from him since last Wednesday. I’m currently out of town for a few days but I’m going to send the amp back ASAP. Really bummed but I guess that’s the way it goes sometimes.  

Well good luck to you and every at bat is not going to be a home run.

You say that Raven thinks the amp got damaged. When I received my Nighthawk it was not packed well at all. I even called them and told them that I was very disappointed at the packaging quality and effort, or lack there of, put into it. However, I think it's more of a tube issue than the amp issue. If the amp gets damaged, chances are you're going to have a dead channel or two not just a hum. Just my two cents.

You did say you had a crackle out of one channel. I also had a crackle out of one channel in my Nighthawk. Ha... funny.

You then go on to say that this would be fun and expensive addiction.

???

Sorry but how is that fun? How is it fun to purchase a brand new $3,000 amplifier and have issues right off the bat where the manufacturer thinks it may have gotten damaged and then you also have a crackle in one channel? 
Sorry, to me that is absolutely unacceptable and is exactly what I told James when I spoke with him regarding my disappointment with the amplifier. 

To me, that is not the type of fun I want to have, especially with expensive addictions.

i would add here that i very much believe that makers of hifi gear, big or small, have a responsibility, even a duty, to their customers to design and supply excellent packaging that provides safe and trouble-free transport of their gear in this age of fedex and ups with their high speed sorting machines and conveyors, not to mention overworked and tired drivers/delivery people

for amps and speakers that weigh alot, are often quite bulky, and are worth thousands of dollars, there is simply no excuse for not having a packaging design that is completely thought through and implemented without being cheap or cutting corners

exemplary small biz cases of this are vladimir at audio mirror, and frank van alstine... terrific products, terrific packaging -- on the bigger end, audio research and conrad johnson set the bar for being absolutely top notch

others, evidently, not so much - tis a shame and a disservice to the customer
