Weer een mooi stukje historie vanaf de pen van Tom Thiel.

Story time: You all may or may not know or remember the deep recession of 1982. The Stock Market tumbled, expendable income plummeted and the emerging high-end industry took a hard hit. Many manufacturers including Acoustat (and I don't now recall other brands) went under. Many manufacturers dropped out of the June 1983 CES in Chicago - which felt like a ghost town compared to prior years. This was our 7th CES (before Las Vegas began), we had yet to make a profit, and we knew we were gambling on a flagship. The concept was the same as the 03 / 03a / 03b, but the execution of the curved baffle, highly customized drivers and next-level XO components put it in a higher league. We hoped folks would notice.

There was always a pre-show walkabout the evening before opening. We had a mostly European purist recording following who always brought master-tapes and headphones to compare notes from studio to showroom. The Danes had been to KEF's new Reference 105 demonstration, claiming "phase correct" presentation. They also did their homework and reported the drivers as being time-aligned, but using high order filters and scrambling their test tracks.

After the niceties, the new works began rolling. Lights out. Spaced omni capture of a live jazz ensemble, ending in a barely-audible triangle tink. It faded forever. Long silence. Applause. And the night went on somewhat like a dream. 

We had come to the show with a tentative retail price of $1250 / pair, a little advance from the 03a at $1150. We, especially Jim, feared a glass ceiling for a dynamic speaker from a fledgling, uncredentialed company at $1,000 / pair in 1983 dollars. These were frontier days, not only in Audio, but in boutique manufacturing generally, and on the heals of the deepest recession since the great depression.  Uncharacteristically, I surveyed the attending guests, about 30 sophisticated insiders and industry associates, asking what a proper price might be for this thing. The 'auction' suggested $2K - $5K. Everyone was elated.
We stayed up half the night discussing everything: the nature of our niche, the disparity between a few deep fans and 'the market' at large, the times, and the real settled costs of putting this thing into production. Note that each baffle was hand-sculpted by yours-truly in what might be called shop-jujitsu. We were pulling this thing out of our hats. Big sales were the enemy of stability and sleep. One key equation was that if I were engaged in hiring, teaching, coaching and managing new cabinet makers to produce this complex cabinet, I wouldn't be available to make baffles. Production is not prototype and we needed production to break into profitability and survive.

When the room quieted around 3:AM, we had decided to introduce the 03b at $1850/pair. 03b? Well, it was the third version of the 03 and our system assigned that name. Jim predicted that we would loose most of our dealers, since our niche was unbelievably inexpensive / unexpectedly good performance.

Next morning before opening, Peter Moncrief of The International Audio Review came to visit - he had heard talk. He was full of the right questions. He got answers he loved. He listened. He smiled. Peter pronounced that we had found the holy grail, that we had created the illusive and rumored impossible "Coherent Source" transducer. We christened it CS3 - Coherent Source, third generation model 3, and had the show of a lifetime. The room was packed full-time. Comparisons to KEF and B&W were flying. Only one east-coast dealer dropped our line - and was replaced by a more appropriate player. The CS3 turned our tide.

Was it a bugger to make? Yes. Did we struggle to meet demand, yes. Did we rise to the opportunity? Partly. The CS3 was our watershed. It caused me to take a huge plunge and adopt CNC machining in its infancy - as a first-tier user. We mortgaged everything, and still couldn't manage the $6-figures investment. Banks had no money to lend even if we might qualify.

Then magic happened.

Remember Scott Estes, the Maggie Man reviewing for The Sensible Sound? Scott had become a friend. Kathy and I were commiserating with him about the bucket-load of orders we couldn't fill, the back-order that could bury us . . . and he volunteered news of an unexpected inheritance which he was willing to lend us on the strength of his belief in us. Oh My God. He funded the critical corner, the one that might not have been navigated. The CS3 real-cost equation required a price increase to $1950 at the first Las Vegas CES in January 1984. And that was just fine with everybody.

Of course new learning superceeds old performance and new products always perform better in some ways. But nonetheless, the Thiel CS3 is a true classic in our corner of the history of the development of American High End Audio. And I hope to find a way for it to live on. R is for Renaissance.

Filter op het mid/hoog van mijn Kef R200c centerspeaker beetgepakt, dat scheelt even een jas zeg!!

Gebruikte condensatoren uit de oude doos gefilterd waardoor niet het max haalbare uit het filter gehaald wat met specifiek gekozen condensatoren zeker een nog beter resultaat zal geven, laag filter vooralsnog met rust gelaten omdat daar veel minder te halen is.
Deze center heeft ook (zoals alle Kef speakers) een gescheiden laag/mid-hoog ingang die te koppelen is met klem schroeven, als je ziet hoe Kef dat uitvoert en de daadwerkelijk verbinding tot stand brengt rijzen je haren te berge!! deze zijn nu dus door gesoldeerd, net als alle schuif verbindingen.

Ook hier is het weer duidelijk te zien hoe ondermaats fabrieks filters eigenlijk zijn!! zeker gezien de erg fraaie Kef mid/hoog unit die duidelijk laat horen dat hij VEEL!! meer in zijn mars heeft.


Waarnemingen na de upgrade,

Meer detail
Vloeiender
Minder scherp/grainy
Geluid komt veel meer los en koppelt beter aan de main speakers

Op het head-fi forum zijn ze er iig erg positief over, en jij natuurlijk ook René, maar magna heeft ze in bestelling staan en zodra binnen gaat mijn R8 die kant op, zal rond de 3 weken geduld moeten hebben voordat ik het kan ervaren.

Door de overtuigingskracht (erg mooie prijs :D) van de aanbieder wordt het toch een 2019 model oftewel de LG65C9PLA  :headbanging:

Ten opzichte van de C9 bedoel je? ja dat is wel een hele flinke stap vooruit, meest opvallend is Dolby Vision natuurlijk en totaal geen last meer van black artifacts.

Wat screen shots,

Jep, t.o.v. De C9, zag de update met het vriendelijke prijsje te laat :angel:.

Is de motion processing, vooral m.b.t. panning nog veel verbeterd? Dat, samen met de black level crush zijn de enige twee verbeterpunten van de EF serie voor mij.

De leidingen van je AC zijn wel mooi afgewerkt zeg!! :eh:

Nee, dank je. Geeft een beetje beter beeld en het lijkt dat het langzaamaan goed komt met de LG motion algoritmes.

Ik heb iig nog niks gezien wat mij niet bevalt, maar ongetwijfeld zal de volgende TV over een jaar of 4 nog mooier/beter zijn.
