I recently purchased a 2.5 meter pair of the Ecosse MS4.45 and put them to the test with Dali Hallcon 800 speakers ( with a super ribbon tweeter ), a Cary 30W integrated tube amp, and a Rega Apollo CD player. Very smooth and very listenable. Accurate in the mid range and delicate with the highs.... a bit thick in the low end, until the tubes warmed up and then.... wow. The MS4.45s are a great value and provide a delightful presentation of all types of music.
I also tried the MS4.45s with a Vac 100W amp and a Cary pre amp, but prefer the 30W integrated as the Dalis are 91db efficient. The 30W Cary is very smooth, while the other rig was a bit too punchy with the MS4.45
