The AN/3 plant? Rudy J. van de Plassche and his colleagues at Philips Research Laboratories (NatLab) got the basics right in 1976, when he published his first paper on Dynamic Element Matching.

Excellent tweeter, especially the original vifa (later: Peerless/Tymphany) with rear chamber:

Until recently, R. Magalotti (also former B&C) was head of acoustic research at B&W. He undoubtedly knows a thing or two about acoustics and speaker technology. Personally, I lost interest in B&W products a long time ago. However, at the time (1990s) this was a decent (sounding) small...

Assuming one's happy to be scourged by Bextrene's (hideous) signature. If a (hi-fi) loudspeaker needs more than a 'handful of watts' to come to life, it's basically defective. Even if you are convinced of the 'importance of SINAD' as an indicator of 'quality', a 2x 40 watt amplifier has been...

Like +99.99%?

Is it? "The best sounding gain devices in the world are linear gain. The triode tube is linear gain and is TRULY a quantum device to boot. The only linear gain solid state devices in the world, are the SIT, and the V-fet. The rest, and I do mean ALL of it, no exceptions, no mincing of words...

Nearly 600 pages of navel-gazing. Fascinating.

Indeed, which likely contributes to the perceived 'slow/sloppy' bass at higher output levels. The woofers in my bigger 2 way system are 102 dB and don't drop below 5 ohm, so the CT 8150 is basically overkill > due to the high efficiency/easy load. This might improve performance (slightly)...

Technically, it's the lack of current the amplifier is able to maintain (load regulation). As Atkinson states: "The speaker's impedance plot (fig.1) reveals it still to be quite a demanding load, however, with a magnitude that drops to 2.5 ohms at 104Hz". Here's a more in depth explanation.

Quite remarkable that you've "upgraded from the Purifi 1ET400A to the CT8150 and 4150";) While not exactly ideal, the impedance drop at 100 Hz should't cause problems in normal use (i.e. not THX Reference Level).

3 ports:

The impedance of the Magnepan 1.7 drops below 2 ohms above 10 Khz, which can be 'problematic'. This may also be the case for the 1.7i.

And SINAD equals sound quality... :facepalm: There is no definitive explanation of the constituents of sound quality. Definitions of sound quality include examples such as: “Sound Quality is a perceptual reaction to the sound of a product that reflects the listener’s reaction to how...

You won't get many thumbs up, while - or precisely because, this quote touches on the essence of (digital) audio reproduction.

It's quite remarkable that a thread like this evokes reactions on this "science oriented" forum. Although I'm familiar with audio science, I feel no need to preach to those "blinded by science". Fortunately, experienced professionals also post here who know what really matters and what...

Haven't watched the video myself, as I avoid most of the audiophool blurb. However, you'd better get acquainted with the more philosophical thoughts of people like Niels Bohr and Max Planck. Just don't confuse "reading" with "knowing". In any case, during the early days of this forum, amirm...

It's all implementation, including the signature of specific materials. For those who don't agree, buy Magico.

They don't need to, because the majority of 'western' brand loudspeaker(parts) are produced in China.

This might be a better option.

Yes, it's the output buffer. Assuming you know what you're doing and what to aim for, then the LT (family) seems worth experimenting with. "LT1355, LT1358, LT1361, LT1364 - a family of op amps with high (LT1355 and LT1358) and very high (LT1361 and LT1364) slew rates (from 12 MHz and 400 V/µs...
