Ok, so I'm not really going to talk about the show itself, but more of some interesting things I learned. Yes, I did have a room, but that's not the point. I was able to borrow some speakers from Azzolina. They are of the unusual Lo...

As they told, the APS UPS unit was sent back to the manufacturer where it was exposed to further thorough retesting. Preliminary the results of re- testing turned out to be very contradictive with that results that I got in mine listening room, and t...

Hello all :::: This will be my first post, and I am writing first to thank Romy and the lovely Koshka for making the results of their research available to others, and also to ask for help :::: I am something of a "New Horns Guy" (cringe !), as I am ...

Interesting, Ulf.
If your horn runs up-to 500-700Hz (somewhere like mine) then what kind “beaming” you meant? Frankly speaking I did not detect any beaming at those frequencies, quite in contrary – it is very difficult to make anything to beam at un...

I got some time on the PC to start to think about how to layout the DSET. I plan to build it a little like a skyscraper: multiple levels separated by component groups and functions. So mains transformers, AC socket and perhaps time delay rel...

Today I listened to a CD of Dvorak's 5 & 7 by the Slovak Philharmonic, conducted by (American) Stephen Gunzenhauser in 1989.The orchestra is better than good, at least for the 5th, and the sound they make can be awesome, despite the poor Nax...

Above I was discussing the new integration process I used to mate the tapped horns with the rest of the system. Below is a graphic to help explain the listening arc. I just moved the tapped horns along an equal-distant arc until the phasing of th...

The most interesting thought to come out of this thread for me is surfing the wave versus making the wave (or, making a part of the wave...).Personally, I just enjoy listening to great music in my home, and I am happy any time this can happen. ...

Interesting. I remember getting low contrast levels when using the asa 32 film (I think it was pan-x), but huge grey scales. Sometimes I shot in tri-x just to add drama. In the end though, my best prints were from the pan-x using ne...

Hmmm... Thorny, difficult topic...The "integration" of HF certainly involves its "disappearance" - as "HF", as such - "into the soundfield". At the very least, Tone ultimately depends on this. But there also appear to be other benefits from "ge...
