Keep in mind that should you go this route you are likely to get zero support from the US distributor should you have a problem in which the component requires service. This may not seem like a big deal, but there's a very good chance that you'd need to send it back to Japan (or whatever country you purchased it from) in order to have basic service performed. This comes up quite a bit with Luxman and Luxman Japan will not provide any parts for a grey market unit in the US. Parts orders require a serial number and if the serial number wasn't originally sold in the US then you have a very expensive doorstop.
As an aside, I've been reading your posts regarding your search for various components to match with your Maestros. While shopping is fun you would be wise to take delivery of the speakers first, go through the very long break-in process, and then start looking for components that you can evaluate in your system. The Maestros are EXTREMELY revealing and will highlight even the most minor change in your system. Hyper-sensitive is probably the best term that I can come up with. When you get it right they are wonderful and one of the best I've ever heard... get it wrong and you'll be sorely disappointed. There's nothing inherently wrong with your Pass amp and it will drive the Maestros with aplomb. Based on the list of components you posted elsewhere I would highly recommend that you try a few different DACs first. That experiment in itself will give you an idea of just how revealing the Maestros are. I know you are coming from the Electra series, but I can tell you that the Maestros are nothing like the Electras.
Tread carefully and you will be greatly rewarded. Shoot from the hip and it will be very expensive with very little gain.
