I am following up on my post when a first received the Purple fuses many weeks ago. They have burned in nicely, although I think they sound much better right out of the box than past versions.
Everything has gotten even better, with more overall thrust and solidity, yet at the same time, a more liquid and detailed sound with cleaner and more piercing transient attack. Imaging has improved and soundstage size has increased. Let's face it, $200 is no small amount for a fuse. Though, this has been no small upgrade and has been more subtsantial than many component upgrades that I have made. Dollar for dollar, euro for euro, these may be the most cost effective upgrade that one can make in a stereo system. I would upgrade to the Purples before spending money on anything else. Very impressive and I find deep solace in the fact that any naysayers will never enjoy this level of performance.
