I tried a Simaudio 340i, Arcam A28 and the T+A power plant MkII with the Dyns and found the T+A to be the best amp. The Dynaudio's just came alive with all that power. I now know why people have always said that Dynaudios love power. The Simaudio sounded a little too polite to me and the Arcam was not bad but just didn't have the punch of the T+A... especially in the lower octaves. I couldn't be happier with the choice. Plus the T+A looks awesome, has recessed connections and a very well functioning loudness button for late night listening. On top of that its extremely energy efficient using only a fraction of a watt in standby.
I went with JPS labs Ultraconductor 2 cables all around and have been very satisfied. The midrange seemed to be "clearer" and more airy compared to my Analysis Plus cables.
