Hal do you have any plans for demos at CAF 2025. It's closer than you think!

Danville Signal will be demoing at CAF2025 this year. I asked Gary to set them up in the same room.

I will help with room setup and tuning, but they have a system to show with the dspNexus 2/8 and possibly the new 2/8 small DSP. It will not be the same system demo as last year or AXPONA2025, but it is still in planning as to the final system.

Hopefully I will be there for the full show as well, but not sure due to family health issues.

OK. It is tiring when someone has to verbalize their resume bragging about all the many years experience.

Is it 60-years experience -or- is it 60-years of the same experience?

There are those that know what they don't know -and- those that don't know what they don't know (aka. self-proclaimed "experts")

And my experience has been that I made a lot of money (engineering forensics) off the backs of those those that don't know what they don't know.

It is 60 years of listening to all sorts of different equipment including vinyl, digital, vacuum tube, transistor, building speakers, electronic devices both in the audio field and the photo field, running lots of double blind tests, and acting as a judge at speaker design competitions. I have also been writing for the Audio Amateur, Speaker Builder and audioXpress magazines for 30 years. There are lots of other things but this is a short synopsis of my background. If you read my articles, I do mention what I don't know in certain areas, for example room acoustics where Anthony Grimani did the design of my room treatments.

Tom when you demonstrated the “Eggs “ at CAF one year I thought they sounded great.When I heard them at your house in Potomac not so much. The difference was you replaced the analogue crossover with an active one.

I think you owe it to yourself to come up and hear what it sounds like now. The problems in Potomac were primarily the room. There were lots of early reflections in that small room with the speakers close to the reflecting surfaces. Definitely worked against the design of the eggs to reduce diffraction and comb filtering effects. Also, the DSP was the old DEQX which was good in its day but comparing that to the dspNexus is like comparing the first IBM PC I worked with to my current Dell XPS laptop. Not in the same league. Time moves on in all technologies. BTW, if you read the upcoming November issue of audioXpress where I will have a review of the Nexus, you will see my path with electronic control of audio going back to the original Bozak N106-A electronic crossover I used on my Bozak Symphonies to replace part of the passives..

Walt:

FYI, here is what I said in the first paragraph of my article that appeared in this month's audioXpress where I say what I don't know. I have always made it clear to the readers what my limitations are.
