Da, ali izmerene vrednosti i nisu baš značajno drugačije od onih izmerenih kod constructor-a koji o tome (pa i fanatic) vode računa...
Dopada mi se mogućnost izbora zadate impedance i time...
Update₁: i ovo je LDR...?
"Fully discrete gain stage" sigurno nije LDR.

Onoliko koliko sam uspeo da shvatim iz raspoloživih izvora, LDR ili nešto što liči na to (izgleda da je autor pokušao da zaštiti patentom tehnologiju, pa kasnije odustao...) se koristi za potenciometar, a proprietary light switching kolo za izbor ulaza. Rekao bih, sasvim dovoljno svetla u jednačini da se može smatrati da ipak jeste LDR. :wink:

Anthem A Series

Image
A2
2 channels, RCA and XLR inputs, 225 continuous watts per channel into 8 ohms, 4-layer circuit board for low source impedance, Statement-level parts with hand-matched input stage devices, 2-ohm capability.

“NO FUSE” DESIGN
A2 and A5 amplifiers are Direct-Connected to the power supply capacitor bank, keeping output impedance remarkably low while making more power available to the amplifier. Even when the amplifiers are driving lower- or complex-impedance loads, the result is audibly superior performance. If an output short circuit does occur, only the AC line breaker will trip—there are no fuses to replace. The standby low-power supply is protected by self-resetting Positive Temperature coefficient thermistors (PTCs). Once the condition that tripped the PTC disappears, the circuit restores itself automatically. ...

Veoma dobro,
Ili kako kaze moj prijatelj Orlin iz Bugarske:

Страхотно хубаво, Искам го!

World's first 384 kHz converter, phono stage preamp and headphone amplifier with an integrated atomic clock

Rubidium Atomic Clock
Rubicon is the first DAC to integrate a Rubidium atomic clock, which is 100,000 times more stable than a traditional crystal oscillator. Coupled with Antelope’s 64-bit Acoustically Focused Clocking technology, the Rubidium achieves a breakthrough in jitter management, improving the sound quality in an unprecedented way. The same technology is implemented in the company’s flagship master clocks used for scoring blockbusters such as Avatar and available at the best recording and mastering studios around the Globe.

Advanced technological fusion
The transformer-based, ultra-low noise, discrete JFET phono preamp is a complement that will be highly appreciated by many vinyl lovers. In addition to the 384 kHz DAC, Rubicon also includes ultra-high sample rate A/D conversion. These functionalities together with the high resolution USB recording capability provide the users with the sublime experience of digitizing their favorite tracks, still keeping the depth and the warmth of the original analog recordings.

DLNA streaming capability
In addition to the 384 kHz USB streaming, Rubicon offers extended flexibility and smooth user experience provided by the implemented DLNA capability. The DLNA streaming gives users the opportunity to wirelessly push audio files from their smart phone, PC or NAS (Network-attached storage) server and play the content through the high-sample rate DAC.

Izgleda da umreš, a i cena od 40k US$ je da ti srce stane...
