Thanks to all those who advised me a few weeks ago. After listening to what systems I could, I had a clear favourite, maxed out the budget and bought a Rega DAC, Brio R and RS3s. They made my Marantz CD player sound gorgeous in the shop and provide a nice path to streaming if I want to go that way later. Now after a long wait they have finally been delivered. Can't wait to get home and set them up!
