I had B&W 802D's, powered by TAG McLaren 250*3R's (now for sale !) when I bought my 861v6.
My source is a humble Squeezebox Touch, but I was very impressed & pleased by the processor upgrade.
This then led me to investigate the DSP7200 speakers, which finally led to my purchase of DSP8000.2's - and I don't think I'd ever go back!
