Xtian,
The last post immediately stuck to me that you are missing the correct "gain" in your system. Then I checked the spec on the ProAc and find that they slightly less efficient speakers. I have had similar experience when I moved to a larger volume room. After I got the correct gain, my speakers now sound awesome.
The Rega is 50Watts, while the Leben is 15W. I think, for the ProAcs to sound better, you might need more power. So going to Leben may not help. The Harbeth is less efficient. Now understand that I am basing this all on the numbers I am seeing on the component sites.
Do you have anybody close by that you can reach out to, who has a more powerful amp? You might want to try that amp in your system and see if you get back what you are missing. That might be your solution.
My system doesnt have the weight and body..
