I found Bundee1's response interesting. I too have a pair of KEF Q5s. I have only had them for a month on my second system. I haven't really been impressed by them and was thinking of ditching them. The added burn in time, although admittedly not lengthy, wasn't adding much if anything to the sound. Unimpressive depth and rather thin on the high end. I had them bi-amped with matching Carver TFM-15s and bi-wired with Kimber Kable 4VS but still didn't like what I was hearing. Maybe my positioning needs improvement. I will try that first.
Thank you for your comments on my music system. The Sunfire does not have DAC capability. Maybe another purchase is in store for that system.
Like what you have done. Maybe try some similar things with my primary setup.
