| Tube Amp for Martin Logan Speakers Al, perhaps the EPDR article I referred to above might put a little gloss on what you said. The underlying thesis of the EPDR article is that a speaker's "nominal" impedance is further reduced if it is coupled with a negative phase angle at the pa... | |
| Tube Amp for Martin Logan Speakers That's right George. My ARC Ref 150 might (???) be able to handle the current demands because it has a beefed up power supply -- 1040 joules. And, as I mentioned above, the output impedance off the 4 ohm taps is roughly .5 or so ohms. As a result,... | |
| Tube Amp for Martin Logan Speakers Thanks Al .... that's exactly what I surmised the directionality of the impact might be. Btw, if ZEROs are used to double the ML's apparent impedance plot, would that change your calculations?? And your comment about whether any amp, SS or tube, c... | |
| ARC Ref CD-8 compared to CD-6 and/or Ref CD-9 There's a couple of vendors out there. I started a thread, titled something like "Redbook CD is Not Dead." A couple of members posted some web site where hi-rez redbook CDs can be purchased. In the meantime, I've bought quite a few hi-rez redbook ... | |
| Tube Amp for Martin Logan Speakers Quick postscript: my posts are not just academic. The OP is asking about matching a tube amp with ML ESLs. My comments are trying to focus attention on whether the ML ESLs in question should be driven by a low impedance amp that acts as a constant... | |
| Tube Amp for Martin Logan Speakers Tom, if you read my posts, I framed my question by referring to those tube amps having a "high'ish" output impedance (say 3 or 4, or more ohms). By contrast, some amps like my ARC Ref 150, have a "low'ish" output impedance, possibly because they u... | |
| Tube Amp for Martin Logan Speakers Thanks for the Stereophile URL link Unsound. My tongue-in-cheek quip was dead-on: the MLs should be driven by a hydroelectric plant - actually 2; one for the ESL panels and the other for the woofer. :) | |
| Tube Amp for Martin Logan Speakers George, again with respect, all your last post tells me is that the Levinson amp is a Constant Voltage Paradigm amp which doubles watts as ohms halves. Your post also states that the Levinson can deliver power into a near short, .5 ohms.But that d... | |
| New KT150 tubes? Wolfy ... I think what Tsushima1 is saying is that you are a lowbrow. LOL Not to worry ... my wife says the same about me. ;-) | |
| Tube Amp for Martin Logan Speakers Ralph and others, with respect, do you know for a **fact** that MLs or Quads were **designed** to be driven by a Constant Voltage Paradigm (SS) amp or a Power Paradigm (traditional high'ish output impedance tube) amp? Seems to me that just because... | |
| ARC Ref CD-8 compared to CD-6 and/or Ref CD-9 Jafant, I thought the CD-8's sonic presentation was livelier and more transparent than the CD-7 in all musical applications. As I recall, because the CD-7 was a bit bass thick, this characteristic tended to over-emphasize the low-end of rock, jazz... | |
| Tube Amp for Martin Logan Speakers Well that's kind of an important question Mapman because given the wacko impedance plots of these ESLs, hooking them up to a high'ish impedance tube amp could really color their sonic presentation if indeed these speakers were designed to be drive... | |
| Tube Amp for Martin Logan Speakers The title of this thread is "Tube Amp for Martin Logan Speakers." The lst couple of posts give me considerable pause. Let's go back to square one basics. Seems to me the first question that comes to mind is what did the ESL designers have in mind?... | |
| Tube Amp for Martin Logan Speakers Thanks George. Very interesting plots for the Quads and MLs. Looking at the Quads, I see the bass impedance spike is literally off the chart. Heck, it's almost an open circuit. I don't know, .... schlepping around a 75 amp to a dealer ... auugh. I... | |
| Tube Amp for Martin Logan Speakers George, not having ever used the ZEROS, I can't speak to their pros or cons. Having said that, as I mentioned in one of my posts above, I tried a couple of gizmo tweaks in the signal path in various places and was disappointed. So, I suppose based... |
