Rugby1- I believe St. Louis Stereo carries both DeVore and Harbeth. I am not sure if they have Orangutan's, and the larger Harbeths. If they do, perhaps they could shed light on the comparison. If it helps, I am driving the little Spendor 3/5 R's in a 2nd system w/ an LM 211 integrated. It's in a small room, but it is enough power. I am impressed with the Spendor, especially for the $ I have in to them. I will soon have an analog setup w/ the Spendors, and that is when I will make a true judgement. I guess even though the 3/5's are lo efficiency, their 8ohm impedance make them more tube-friendly. Certainly your 75 tube watts should be fine with SP100R2 or 40.1. That said, an Orangutan or AN An-e would allow you to use lower power in the future.
