The sound engineer on one of Weiss’ films had bought an old farm there and Jonathan helped him renovate it. OMA’s roots, however, reach back to somewhere else entirely: Pennsylvania. At the time, Weiss was living in a large loft space in Brooklyn, which also doubled as his film studio and would later become the home for OMA. He studied international relations and political philosophy at Princeton University as well as public international law at the London School of Economics.īut that didn’t stop him from becoming a filmmaker to begin with.

Weiss is a textbook example of how to start a completely different career. For a good 10 years now, OMA has been developing, manufacturing and selling unique loudspeakers, turntables, tonearms and tube amplifiers. And inside you’ll discover Oswalds Mill Audio (OMA), which is where we met up with the company’s founder, Jonathan Weiss. Once there, you’ll find an attractive brick industrial building dating back to 1908. To discover something truly unique in New York, you just have to get yourself from one neighborhood over to another: in this case, from Manhattan over the East River to Brooklyn and eventually to 110 Bridge Street. *simply click the “English”-Button in the German article to get the text in english. Our report on hi-fi retailers in New York* reaches the rather level-headed conclusion that, in a direct comparison, German specialist retailers usually have the edge – but Oswalds Mill Audio, or “OMA”, is simply unbeatable! And they image like crazy by the way.Is the US really the Land of unending opportunities? Is everything there really bigger and better? No way.

Admittedly phenolic drivers do sound sort of soft, but the treated paper cones in my DCM50s do not sound soft, just smooth. I also listened to the DCM50 without a horn FWIW and it sounded great that way too, not much different, except for a bit less bass than it has on the AH300. I was able to play one side at a time using mono sources and the B&C+AH300 was far more to my liking. To compare paper 'cones' to aluminum domes I left one side of my stereo setup as it was and replaced the JBL driver+tractrix horn on the other side with a B&C DCM50+AH300 conical horn.
Same thing basically with Jensen drivers in Imperials and EV drivers in a Patrician in comparison 375s+077s in Hartsfields sound slightly tizzy, metallic. Vocals and spoken voice sounded more realistic. I was using 375s when I found the 2482s and in comparison the JBL phenolic drivers sounded quite different, lots more low end, much smoother midrange and way less highs. Something that really stands out to me about the DCM50s is how much easier it is now to clearly understand lyrics and hear really-low level detail. Anyhow, I am satisfied with the B&Cs, my system sounds more realistic now. My 375s were frustrating, I was always bothered by the slightly tizzy, metallic sound even though I really liked them overall. I regret selling the 2482s, think they could work well in a home system. Years ago I found a pair of JBL 2482s at a flea market and I liked those too, nice mid/upper bass but they needed tweeters badly (wonder how 2482s sound with the 2470 1" drivers with phenolic diaphragms). My experience is with vintage drivers mostly I always liked the sound of old Jensen and EV drivers with phenolic diaphragms "quieter, smoother and much less artificial" as you say (but the paper cone B&Cs sound much better). Hi POOH, I have not tried the drivers you mentioned, they both look interesting, especially the JBL CMCD, which really does look like a conventional direct radiator in a compression-type housing. I have a pair of DCM50s on Acoustic Horn Company AH300s and they sound great, far better than JBL 375s on 300 Hz tractrix horns. Another modern version of the 1428 is the B&C DCM50.

The early diaphragms are treated paper, later diaphragms are phenolic coated fabric, both have chamois (goat) leather perimeter surrounds and mount to the driver with a screw in the center (+perimeter mounting screws). The RCA 1428's range is 300 Hz to ~10kHz. I have heard original RCA 1428s on RCA horns and they sound very very good, very smooth but quite detailed, without the irritating metallic quality of metal domes. I have never heard the Cogents but the designer/maker Steve Schell says they sound better than the original 1428 and I believe him (they damn well *should* sound better considering the build quality and the price). The Cogents are basically modern versions of the 1930's vintage RCA 1428 field coil compression drivers. The Cogent diaphragms may look like direct radiator cones but they are not.
