I have no first hand knowledge of Spendor speakers, but I recall reading a review on Musical Fidelity's current M6 product line that specifically mentioned a couple of speakers that pair very well with M6 components. One of the speakers mentioned was the Spendor S9, so to the extent that the A5 may have similar characteristics to the S9, then the Musical Fidelty M6PRX amplifier would probably be a good pairing. The review I am referring to was by Alan Sircom and published at avguide.com.
I use the M6PRX with B&W 804 Diamonds, which is a combination that I like although it is not one that Sircom mentioned. I suspect a used M6PRX would be in the vicinity of $2500 or perhaps a little bit more. It's an outstanding amp that you don't hear much about, which is a little surprising given several absolutely glowing reviews.
The only caution I have about the M6PRX is that does run on the warm side so it's definitely not an amp that I would place inside any kind of cabinet.
