I currently have a Rega DAC and looking to upgrade in the near future. Ayre QB-9 DSD is on my short list. Is the Ayre significantly better in terms of sound quality over Rega? I love the Rega sound: warm and musical. Lampizator is also gaining popularity recently. Are people switching from Ayre to Lampizator? Is lampizator 4 or amber dac better than Ayre?
