Not sure what currency the "buckagroo" is, but I might consider a less limiting power conditioner for the amp such as a PS Audio Ultimate Outlet (you'll need the High Current version, I'd think, for the Bryston), which can be had on the used market in excellent shape for around $225-275. Other solutions may limit your dynamics when used on the amp. Do you have a power problem in your area (does you system sound significantly better at night than during the day)? If not, perhaps dedicated lines with good wires and outlets might be the way to go and can be had for less than $500 by a competent electrician in most applications, like a wood-framed house for instance. It is something to weigh against the power conditioner option. In some cases in may have a greater impact and give you more bang-for-buckagroo!
