Yamaha AX-700 versus AX-700U with Infinity Crescendo CS3009 Speakers
Hi. First time posting. I have lurked for three months and want to thank all of you for the great education you have been giving me. You guys are truly fantastic!
I am just getting back into owning "traditional" 2 channel audio components as a recent empty nester. Prior to now I have only swum in Technics, Pioneer, Sony waters. So far, I have purchased a pristine pair of Infinity Crescendo CS3009s and a Yamaha AX-700. My intention is to keep the Crescendos long-term. The Yamaha's life span was unknown and is part of what I would like your help with.
First I would love clarification on what the Crescendos REALLY run at -- I have read 4 ohms and 6 ohms -- the manual says 8 ohms. Everyone agrees 8 is wrong. Can anyone definitively clarify the ohm rating of a Crescendo 3009?
Next, I can't find a manual for the Yamaha AX-700. So far, the AX-700U is getting all the manual love. The problem is, where HiFiEngine info represents the AX-700 as 110w at 8 ohms, I have found the 700U manual, representing the "U" at 160W/210W/280W (8/6/4ohms). What a difference!
Was that "U" that much of a tweak or is there a misprint somewhere?
And what is the 700's 6 ohm and 4 ohm rating?
