From a lady: between Krell Kav-300CD and krc-3series2 pre, I had great results with Harmonic Technology Pro-Silway 2 XLR. There is now a Pro-Sil 3 available, but I can't currently find a supplier here in UK so haven't heard it. UK distribution, anyone know? This last week I've been burning in a Wireworld Super Eclipse 5, and after ca.100 hours the results are stunning. Neutral & well-balanced as is HTprosil, but more of pretty much everything - wider deeper stage, solider 3D imagery, wider dynamic range, and better control in dense orchestral climaxes. Bass is stronger too. Its a more demanding sound, but worth the (considerable) extra cost. So long as your amps & speakers can cope. The Pro-Sil isn't far behind though, if that's your cash limit. Oh and both cables are happy to mix with other brands. I have AQ Python from pre to power. Try a WW SE5 if you can - but give it time. (I burn mine in on a Magnum tuner.)
