In my case, 2 different sets of pricy Mc XRT series line array type speaker systems..
I could have audtioned them, but my electronic repair work load discouraged the time that would be required.
The first was in 1993, when my local Mc. dealer called me up and offered to sell me a pair of demo XRT-18s with the optional and rare stands for the tweeter arrays at a very attractive price.
I felt comfortable with the purchase without auditioning, being that I had recently purchased the XRT-18`s later and larger brother, the wonderful sounding, and dealer auditioned Mc. XRT-22s for my living room system, and was confident the XRT-18s would sound wonderful when setup in my fairly large master bedroom to start to build a stereo system in that room, and their still in daily use every morning and for my listening while laying in bed for a few hours before falling asleep and will remain for the rest of my lifetime.
And their SQ performance certainly didn`t disappoint, especially after I installed 2 L/R configured 400 watt servo powered Velodyne floor firing ULD 15 subwoofers to assist the 18s slightly weak bottom octave, and carefully 1/3rd octave RTA room voicing.
The last non auditioned leap of faith speaker purchase, is my currently in use, and not going anywhere, is the late Nov. 2003 purchased Mc. XRT-30 readily tri-amplify capable (and currently configured) line array excellent sounding speaker system to upgrade/replace the living room`s 13 yr. old existing XRT-22s that I had bi-amplified by then, also no disappointment/regrets with that leap of faith expensive speaker system upgrade purchase.
Over the decades I`ve purchased many used Crown DC-300/D150 power amplifiers without testing/auditioning when they were offered to me at a attractive price, knowing that unless the power transformer was toast, that I should be able to readily and inexpensively repair them to factory specs, as I had most parts on hand needed to do so, being a Crown authorized warranty service facility for a few yrs. in the nineties.
First pic is the bedroom XRT-18s, and the second one below is the living rooms XRT-30s.
