    Beethoven piano concerto eludes me

    Great spotting, sir! That's the one. Here's the link to the Presto Classical website in case anyone else is looking for it. May I ask, how did you find it? Edit: The Adagio is available in its entirety on YouTube. Here Forever grateful, Roger

    Beethoven piano concerto eludes me

    Yup, the same incorrect Brautigam recording. Hence my post here to see if any of our classical aficionados recognized the version used in Ozark. :(

    Beethoven piano concerto eludes me

    Thanks Mike. Yes, that's the recording most search tools cite. Unfortunately it's not the recording in the Ozark soundtrack. :( That recording is a 2011 compilation, link. It includes the 2009 Brautigam performance available from BIS, a totally different rendition. Maybe I will try to...

    Beethoven piano concerto eludes me

    There I was binging Ozark on Netflix, when along comes the entirety of the Adagio from Piano Concerto No. 2 in B-Flat Major, Op. 19 at the close of Season 1. The final minutes of the performance really grabbed me for the measured pace and expressiveness. It is also called Concerto No. 2 in...

    Dirac validation

    Thanks for the great work on the validation measurements. Really useful. Is there a link to the particular info, or can you summarize? Does it have to do with aiming of the mic?

    New Krell Amps.

    A transistor in saturation can still conduct. That's how we make clipping.

    Definition of a Live vs. Dead room?

    True, but I think the OP is asking about listening rooms. :b

    Dido - All You Want

    I found this one to be a worthy successor. Great songs, well recorded.

    Remarkable Video of Ohio Marching Band

    As one who spent 4 years in high school marching band, I can say that was simply brilliant!

    Yes, to me what would be interesting would be for each person to set the given musical track to 2 volume settings: The normal everyday listening level, and the "sometimes I play it louder when no one's home" level. Take the readings for each (A-wtd slow would be my preference for this purpose).

    Constant Power

    Wendell, are you using slow or fast? I assume C wtg. But those of us with "ample" bass may be getting a rather different reading than others without such good bass capability that does not correlate well with loudness impression. When it comes to hearing the distortion products we're discussing...

    When I listen "moderately loud" the peaks (RS meter Cwtd fast) are 80 dB. So to me, 95 dB would in fact be really loud. Just to say that "really loud" is uncalibrated.:b

    That is very encouraging. If the gain stages in the preamp and amp can use feedback, and the current amplification stage needed to drive the speakers can be isolated and linearized independently, we might have a good sounding amp that is fairly impervious to speaker impedance.

    Constant Power

    Great post, Tim. The point you make about using the speakers/room "remastering" to create "realistic" sounding reflections indeed falls apart when the acoustic contributions are not complementary with the music at hand. Alternatively, signal processing offers a way to alter the spatial...

    Thank you, Ralph, for the extensive reply. Much appreciated. I understand the distinction between output impedance with and without feedback. I'd like to see if I can clarify some points about this. Is this not an apples/oranges problem? It is the same error being committed as when a power...

    I very much appreciate your good-natured reply. Be comforted that while the issue was based on your post, it gave me the opportunity to highlight a fallacy harbored by many in these here parts. I hope there's some leftovers to share. ;)

    Constant Power

    Yes. Global feedback has a problem because the propagation delays of several stages compound. That is not a necessary condition for feedback, however. There can be local feedback to each stage, hence no accumulation of delay around the whole amp. This is not a new concept. And to whatever...

    May I inquire, which tube amps in particular? Name several if you like. Thanks. :)
  20. R

    Constant Power

    Or you can use a McIntosh tube/transformer amp (or the like) which has an output impedance of <0.1 ohms. This constant hammering on feedback is getting a little tiresome. There are other ways to achieve low output impedance without global negative feedback. Dismissing all feedback as harmful is...

    Constant Power

    You mean voltage paradigm, no? Are not most amps voltage paradigm? Certainly true for SS amps. I'd say also the case for tube amps. First, we have to use the correct criteria. This "same power for different impedance" is being misinterpreted as a criterion for power paradigm. This has a) nothing...

    Constant Power

    Why do you assume global negative feedback is the only way to achieve a low output impedance? That seems very prejudicial, let alone false.
  23. R

    Constant Power

    If one "Power Paradigm" amp's source impedance is 20 ohms and another is 1 ohm, what can you as a designer rely on for consistency? OTOH, all Voltage Paradigm amps have very low output impedances, thus removing them from the equation as a variable in how the speaker will react, i.e. sound. If...

    If anyone knows, I'm curious: >>Power Paradigm is the method of design, test and measurement<< >>Crossover design rules<< When did the term "Power Paradigm" first enter the lexicon by name? Where are the methods for test and measurement codified? Where are the crossover design rules...

    The link in post 1 did not take me to the article ... missing some characters. This is the full link. Overall, a pretty useless article IMHO. No evidence offered to back up claims. Like this: Ok, what measurements, what rules of human hearing, and how do they relate? BTW, it's not that hard...

    Illusonic Immersive Processing

    Thanks. Yes, I know what you mean. It's one of those things you have to hear. No point discussing too much. Mr. Faller is working out "travel logistics" for this unit, but if it is something you want to try, I will be happy to inform him. Does your sound room have some ceiling speakers?

    Illusonic Immersive Processing

    Thanks much. Yes, PLIIx Music. The SSP-800 does not support PLIIz, and I have not done a thorough test of it. To be avoided at all costs IMHO. Not just because it spreads the front sounds unnecessarily and unnaturally, it deemphasizes the surrounds by reducing levels 3 dB and applying...

    Illusonic Immersive Processing

    As much as I would like to have its processing as part of my system capabilities, I have no plans to acquire the unit. Purely a budgetary matter. The IAP retails for ~2x the SSP-800, and that's not in the cards -- err, the wallet.

    My Immersion Into IAP Preface I’ve been listening to stereo since the ’70s, and was not a fan of quad or the like, what with sound bouncing around rather than creating a cohesive surround space. If one wants to hear a good reason quad deservedly died, pick up the Chicago (CTA) DVD from Rhino...

    Recent Mark Levinson Interview

    Content makers agreed to "legacy" quality for unencrypted outputs. 44.1/48 kHz, 16-bit. But I was referring to native DSD output. You had an outboard DSD DAC? What was the input connector?
