I have also received a lot of feedback from customers that they don't understand all the technical stuff and would like to see something that makes more sense to them. So who do I listen to?
Ah yes that is THE trick. If prospective customers don't get it, then you don't have customers. Some thoughts:
- Your Starkrimson page should mention Starkrimson is a type of pear, and the graphic is a pear tree (I presume).
- You do have hyperlinks from PecanPi and BOSC, but I think it should more obviously state "to read about the advantages of the amp section go here [BOSC hyperlink again]" and "to read about the advantages of the DAC section go here [PecanPi hyperlink again]. Otherwise the page kinda jumps to graphs without much explanation.
- Are those graphs different than the BOSC monoblock? I guess it's combined performance? (admission: I didn't examine in detail).
- Graphics are very important. Like the Panasonic one in this thread earlier, showing the faster rise time. If you say faster "transient response" or "slew rate" etc that means nothing to many folks. If you then explain "That means the amp can respond to the signal faster" and show a graphic, then even kids and the proverbial grandmas can understand.
- Show [graphic A] of typical Class D switching noise, clearly somehow showing where the audio band is and the noise. Explain "Switching noise is an inherent byproduct of Class D. So a physical passive filter is needed to filter out that ultrasonic noise. Here is a typical filter [graphic] which can interfere with the sound. Our gallium nitride (GaN) transistors are faster, so we can switch at a higher frequency farther away from the audio [graphic A2] and so our filter is simpler [graphic] and affects the sound negligibly."
- You say "Higher bandwidth" then show it with measurements of your frequency response versus some similarly priced competitors. I used to instigate that kind of thing in my giant company days, we would measure and call out the competitors. Our sales reps and dealers ate that stuff up. In particular, another giant competitor was touting their signal-to-noise ratio but their DAC was muting with a zero data signal. I made FFTs using the NAD "22.05 kHz 1 LSB" test tone track so none of the DACs could mute, made graphs, published 'em all, showed our noise was lower and smoother. Killed 'em all, in Metallica-speak.
- "Faster overload recovery": why should customers care about that? Aren't we trying to avoid overload unless we clip? What is the advantage here? (Those are my own questions as well; when Class D came into autosound I soon moved into OEM development, so I don't know). Again graphics are king.
This post is huge, to be continued...
On a different note, why not AirPlay? That would be rare and a cool advantage. Is that process to onerous for small makers? (I was involved with Apple licensing but I represented a $3B company so I didn't have to do the REAL work
).
