Seriously, as someone who has demo’d over 20 speakers before choosing D7’s, the Be speakers rank in the top 10-15% of forward-sounding speakers. The classic Spendor ( non-D series) rank in the bottom 10-30% of forward sounding speakers.I would agree with this completely. The A7's are far brighter than the D7.2's.
Spendor D series with LPZ ranks in the middle 20% (40-60). They are neutral, not bright.
I'll also add that I've heard the Harbeths and Spendors. The Harbeths do have a warm midrange; however, they are also very laid back. The D7.2 are very quick, very precise, very detailed, and have a superior low end.
The D7.2's are also less picky with placement. In fact, one of the most forgiving speakers I've owned.
Different people prefer different speakers, and different speakers sound different in different rooms. I would try to demo both in your home.
For me, though, the D7.2's were the better of the two, so I went with them.
