Cesar just responded to my email and I must say he seems like a great guy. He also stated that he should be releasing a 627 with a longer runtime later on this year. I am certainly looking forward to that as that is one of the main reasons I decided to go with the Glacier.
Yes I agree that he seems like a great guy. And that is good news that he is going to boost the battery runtime. If the amp is as good as some folks are saying, it would be a shame if the short battery life kept a lot of people from trying it. Like I said, it does not matter for me, so unless the new version also has better sound, I expect I will be happy with the amp I ordered.
