Knghifi,
What you wrote makes sense. I've listened to the Magico Q3 and Q5 driven by Soulution, Spectral and Constellation power amplifiers and didn't like what I heard (Constellation with the S5 was better, less clinical). I've heard the S5 and S3 models numerous times and the best match IMO was the Absolare Passion PSET 845 driving the Magico S5 (it was pretty darn good!). I've heard VAC amplifiers with the S5 and although decent sounding, I preferred the Absolare amp with this speaker.
Charles,
