King, my room is 13.5 by 21 feet. I listen mostly to classical, some jazz, blues, etc. I wasn’t saying the primaluna wasn’t enough power - note that in at least the nominal ratings the Luxman 509x 120 w/ch is less than primaluna dialogue premium monoblock with KT120s at 150 w/ch at 8 ohms, if memory serves correct. Also, I preferred the PL over a well regarded SS 400 w/ch integrated amp (JRDG Continuum) with the A3s. I just found that the A3s to my taste were much better suited to the Luxman than the PL Amps. For the purposes of this discussion (comparing tannoy with Magico) I was just presenting the best combination of amps I had with each speaker at the time, for sake of comparison. And having owned both, I do think the tannoy is less fussy than the Magico for pairing with amps. That doesn’t mean you can’t use the Magicos with different amps to good effect. I think the magicos just respond better to a quality amp, and I was told by two dealers that “they need high current”, which in my experience is a common trend with sealed LS (and subwoofers). But I have no idea if that is why I liked one over the the other. However, having replaced the Luxman integrated with their M900, which is in fact a much higher current amp (and given, a much more expensive amp), there was a big difference in sound quality. I had the amps plugged directly into the wall with upgraded power cords (PS audio AC-10) with Nordost Heimdall speaker cable. And I listen relatively low, probably about 75-80 db or so without considering peaks.
