@MC,
Thank you for clarifying.

Townshend Maximum Supertweeters
I'm far less impressionable than you insinuate. The 44.1k is in reference to the Nyquist theorem, i'll assume you're familiar with it. Despite being a postulate more than a theorem, it continues to govern the slope of digital filtering applied to the sample frequency. As such Redbook CD's have ZERO frequency content above 22khz. Supertweeters can offer no added value to them. Analog - different story all together. |
Yes, I know all that stuff. Learned back in my impressionable youth. Since then it has been demoted to stuff nice to know but of little consequence. Really only useful in internet arguments where the person never risks being confronted with reality. My listening room, for example. That is where the Nyquist theorem meets the road, and slides right into the ditch. Along with a lot of other meaty sounding sound bites that turns out in the end to be pure word salad. https://systems.audiogon.com/systems/8367 Read the comments. This is where the rubber meets the road. If there was a Great Audio Theorem Graveyard this is it. This is where they all go to die. Not all of them. Tubes, turntables, symmetrical speaker placement, they all thrive, they are going gangbusters. Nyquist, he OD'd on Nyquil. The comb filter died, replaced with the TC brush. Visitors welcome. Encouraged, even. Guaranteed to be an ear-opening experience. |
The germaine issue here is that old geezers can‘t hear above 12 kHz if they are lucky to even get that far. Yet they can tell when a supertweeter with a 15kHz cutoff is present and the effects are wholly beneficial. Go figure what to measure for starters. My take is simply that harmonic overtones, and CD does cover harmonics up to 22kHz, have a profound impact on the perception of the base notes, the exact nature of which requires measurements not yet invented. To anybody prepared to listen carefully, supertweeters, and particularly on digital, are a must for advanced audiophile listening |
