A pair of Solar Winds might work well (used for about $150-200). I have used them in an all Linn system and they worked very well. Detailed, fast, and involving. Also the Nordost bananas work as BFA (Linn) connectors so that no retermination is needed.
You might have to be a little careful that the system does not get to bright since the Nordost will bring out all defficiencies in a system. If you always wanted to see whether cables make a difference, the Nordost will do that.
