I checked with Peter on posting my comments here about our visit to David and he encouraged my doing so.
First, let me express my appreciation for the opportunity to visit David Karmeli and listen to music through several of his various stereo systems. David is a fantastic host with a charming family, all of whom made me feel comfortable and welcomed into their home. His precocious polymathic daughters made for delightful dinner conversations.
Second, it was super to meet Peter and David in person. I truly enjoyed the conversations the three of us we had across four days, typically late into the evening. Right out of the gate, from the airport onward we yapped about audio systems, the audio industry, music, the world in general, along with little side journeys of tales and anecdotes from our life's histories. Our talk was convivial, spirited and uninhibited. David is highly knowledgeable about creating products, putting systems together and making them work well - he knows what he wants and how to achieve that. It was
@bonzo75 who described David's as "
a learning mecca" and I'll second that. I believe Peter and I both learned a lot as we experienced four days of musical magic through David's systems.
Along with meeting David and Peter, one of the reasons I chose to make this trip was to gain in-person exposure to components in system that I've only heard through videos here at WBF. Over the past years I came to realize that while the gap between phone videos and real life is there, by and large videos are faithful (not untruthful) to what they present.
The three systems that took the majority of our time were: a) the Klangfilm Bionors, b) the TAD/Pioneer Exclusive 2401s, and c) the JBL M9500s. I remember Peter asking what these had in common: they are all two-way speakers, with 2 large woofers, 15" on the TAD, 14" on the JBL and I think (not sure) 12" on the Bionor. Each speaker had a single horn for mids and highs. They are all from the 20th Century and they all sound delicious.
In common across these speakers were David's AS2000 turntable with SME 3012R tonearms sporting either a Van den Hul Grand Cru or a Neumann cartridge. For me, the Neumann was profound - easily the best cartridge I've ever heard. On day 1 we also used the NeoDio CD player; I listened to an early version of this machine at CES several years back - at the time it was the best player I had heard. At David's, electronics were all Lamm across many models and versions including the four box 32 Watt ML3 Signature amps, the ML2s, and the M1.1. Front end: the Lamm four-box LL1.1 Signature Linestage and the three box LP1 Signature phonostage. Turntables and electronics sat on David's Nothing Racks or as I called them, The Imperturbables - a knuckle-wrap yields nothing.
I had a mediocre camera and did not get a good picture of the Bionors without the JBLs in front of them. There is an interesting thread started by Alan (
@ALF) from 2015 that I'll point you to:
Speaker Oasis ... Bionor. That thread has pictures, as does Peter's
first post in this thread. Along with the Bionors were two large JBL subwoofers driven by Lamm ML2s. You can also see Bionor and subwoofer pictures from Peter's first visit last year
here.
Here is the left side TAD 2401 at David's March 2022. The amps to its right are the Lamm ML1, a 90-watt push-pull unit no longer in production. There is much better picture of a single speaker (maybe a factory picture)
here. Personally I find these 2401s beautiful pieces of audio furniture.
Here are the JBL M9500s with the Bionors to their back. These were originally intended as studio monitors. Last production was 1997.
Residing in two differently sized cabinets, one of the two woofers covers mid-bass, the other low bass. The small boxes to the left of each speaker are their external crossovers. If I remember correctly, these take a battery and pressing on the gold JBL 'button' will give a light indicating battery status. I speculate the battery is used in the same way as in the smaller S5500, providing "a biasing voltage in the crossover network to keep the music signal from crossing the dielectric zero-point of the capacitors."

On our last day in Area 45, aka the small room, we heard what I remember David saying was a rare RCA speaker . I don't remember the model number. The turntable is a prototype, the amps are Lamm ML2, I believe. Feel free to correct me on any of this.
