What Hi Fi, a British audio magazine, has done quite a number of speaker/amp
shoot-outs involving the Quad 11's over the last two years. In fact, of all the
audio magazines, they have featured the Quad 11's more than any other
magazine. If I remember correctly, they were usually pairing the Quad's with the
NAD C320BEE and the Rotel RA-02.
What Hi-Fi has changed their web site around quite a bit and has taken away the
option to see/download these articles, so you may wish to contact them directly
and purchase the appropriate issue.
I hope this is useful, as I realize you were asking for a different category of
respondent.
