I think an increase in good quality power is always a good thing, especially for certain speakers. I have 2 pairs of Original Large Advents that are stacked and wired in parallel.
I have driven them with the following 4 receivers. Marantz 2252B (52 wpc), Sansui Eight (60 wpc), Pioneer SX-850 (65 wpc) and a Yamaha CR-2020 (100 wpc). They sound great
with all 4 receivers but particularly good with the Yamaha and the Marantz.....so go figure, the two receivers on the opposite ends when it comes to power. Now I live in a condo
so I don't listen at prodigious levels.
There really is something magical about "stacked" Advents.....I never realized it until I got my 2nd pair of OLAs. I'm always on the lookout for great speakers. Have always
had a lusting for Martin Logan and Thiel. But I love the sound of these Advents so much (140.00 for one pair and 150.00 for the other) that I have this fear I could spend
2K on a pair of speakers and not like them more than my Advents.
