With the Atoll and NAD you get a lot for your money. The Linn, typically not so much. But if it sounds really good with the Hawks to you, much better than what you have now, then that may be the ticket. Its all about finding the right match.
If you have the chance to check them out in your area, i I am certain the Plinius, and fairly sure the Nait XS and big Cambridge pair would work very well with the Hawks.
