Not the last word in resolution, but very musical nonetheless. The Harbeths are outstanding performers and will get stronger as the system evolves. Next upgrade nordost Frey 2 Speaker cable, and a Plinius Hautonga integrated amp.
I think we ride the same bus. I'm also a Rega guy (DAC). I urge you to listen to a BAT VK-300SE integrated with NOS "DR" 6H30 tubes. Sweet music just oozes out of your speakers. I can't imagine upgrading.
