I contacted both Ryan and Spendor and both told me that their speakers would work great in my room & with my MAC.
Then, I proceeded to re-audition both speakers (2 different dealers) and I seem to be leaning more towards the Ryan R630 speakers.
They are not as "pretty" as the Spendor D7 but they have a really nice, round, lovely sound with great detail, wide soundstage, sweet midrange, non-fatiguing treble (highs) with a deep/well-controlled bass despite their 38Hz rating. They are really special speakers.
Too bad they don't use a black acoustic felt material around their tweeters so that it would blend in better with the speaker's black front. I asked Ryan about it but they told me that the material they have tested & use only comes in that color. They apparently tried tinting (dying) the material but couldn't get a nice and even finish.
