LUXMAN L509X VS M700/C700U
You didn’t ask about the L-590. It’s a great amp, but probably bettered somewhat by the separates, I imagine. Mountainsong has owned it, as well, and hopefully will chime in. http://www.audiodrom.net/en/integrated-amplifiers/detail/31-integrated-amplifiers/297-luxman-l-590ax... |
Erik, I appreciate the effort, but am still unconvinced of your conclusions. The first Luxman link you cite was provided by me, during one of the ever-recurring threads where people continue to talk about the lack of power in the L-590AX. And as I've stated before, I own that amp. My issue with what I called your "unfounded claims" is based on your conclusion that the amp wouldn't meet the FTC requirements to claim a higher power rating. Perhaps you're correct, but you don't know that, you merely surmised as much. In fact, you jump to a bunch of conclusions about the amp, it's engineering, even going so far as to state what it can and can't do, all without having ever even seen one, let alone heard one, as far as I can tell. What I've surmised (but also don't know for a fact) is that Luxman chose to advertise the amp as pure Class A, and stated the output as such. This seems more likely to me, considering that they never even so much as hint at it switching to A/B beyond that 30wpc. This will be my last post on the subject, the last word is all yours, take care |
rizwanalimohd, I don't have an issue with erik sharing any of his experiences in the least. My issue is when he says things that he heard or read that don't make any sense, at least to me. I asked him to cite his source(s). However, since you're the OP, I'll bow out of your thread, rather than sidetrack it. Best of luck with your search, |
My post up above, with the link to the Stereophile test is poorly worded. What I was trying to say is that the factory power specs for all of Luxman’s non-Class A amps reflect their true output, the 509, 507, 505, etc. The factory power specs for the Class A equipment reflects only the measurements in Class A output, and seems to utterly ignore everything beyond that, after the amps switch to A/B. I haven’t inferred that, but instead base that on the three Class A components that I’ve read actual tested measurements for, the L590, L550, and the M800A linked above. That make more sense? |
Half the time that I say I’m done posting, I eat my words. Oh well. Erik, Luxman’s published power specs are confined to the Class A pieces, from what I’ve seen. The 505/07/09 are all A/B, and specified in a straight forward manner. The L-550 and L-590, both Class A, (but later switch to A/B), but only are specified as Class A. I looked around a little to be sure, this is Stereophile’s review of the now-discontinued M-800A power amp. Also a Class A piece. I’ll not say anything else other than you may find John Atkinson’s measurements interesting. Luxman obviously has reasons for what they do. I don’t know what they are. From what I have seen, the ratings are the same for the non-U.S. models. https://www.stereophile.com/solidpoweramps/1108lux/index.html |
