Samo polako ove bronzane "sfere" nije radio Aca vec :Prof. Nikola "Koka" Jankovic, sculptor; Zoran "Kuzma" Kuzmanovic, sculptor. The sculpture in the back is Nikola Tesla, made 30 years ago by Prof. Jankovic, who gave the Eternity name to our speakers. The bass sphere bronze is carefully cast in Kuzma's foundry and Vladimir Ivanovic is the designer of the speaker's appearance and the one that sculpted the bronze. He will also design our amplifiers to have a sculpted bronze top plate. e sad estetika skulpture je nesto o cemu se moze raspravljati kao i o svakom umetnickom delu...Rukotvorine se mogu podeliti u tri opste klase:1. one koje su prakticno korisne, ali ne izazivaju nezainteresovano dopadanje;2. one koje su i prakticno korisne i izazivaju nezainteresovano dopadanje i3. one koje nisu prakticno korisne, ali izazivaju nezainteresovano dopadanje.Umetnicka dela spadaju u trecu klasu.Nije Filosofski forum da dalje laprdam....Ali da je RAAL filozof u to ne sumnjam

Nelson Pass On The Patents Of Pass 1976—US Patent 3995228: Active bias circuit for operating push-pull amplifiers in class-A mode: [Pass's first patent describes what's often referred to as "sliding bias," where the bias on the output devices varies with the signal to prevent them from shutting off, ergo avoiding crossover distortion. ] There was a lot of interest in class-A operation, but there were practical issues, mainly their size and inefficiency. The maximum power output was theoretically limited to twice the bias current, and really more like half that. I modulated the bias to stretch the bend in the operating curve. Technically, this kept it operating in class-A, but at a lower bias level. The design was successful; the amps sold like gangbusters and were copied immediately. Unfortunately, the approach ended up getting a bad reputation. Our first amplifier, the Threshold 800A, used about a 1:1 ratio, so that it idled at 150W for 150W output instead of 300W. That seemed reasonable and worked well, but some people took it to an extreme. Instead of idling at 150W, there were 200Wpc amps that idled at 10W, ran cool, and didn't have any heatsinks—all claiming to be class-A. In retrospect, we could have sued the copycats, but we were young and foolish, and besides, I had another design waiting in the wings. 1978—US Patent 4107619: Constant-voltage/constant-current high-fidelity amplifier: The patent application actually shows the circuit of the [Threshold] Stasis 1 as the example circuit. This is a kissing cousin to the Quad 405, injecting current into the output for error correction, but with way more current. We had a massive power supply and a huge bank of power devices that we used to support a smaller output-voltage source. All distortions are variations in a device's characteristic with changes in voltage and current. Ideally, you want to lock the operating point of your gain device, the voltage and current, at a constant value, thereby eliminating distortion. Cascoding covers locking the voltage, so for the current, I devised a "current bootstrap," an external current source in parallel with the gain stage. It responded to the current going out and sourced current to the load, outside of the loop gain path. The result was to keep the output current very nearly constant, which dramatically lowered distortion, so we could operate without feedback. These were great amps. They sold for years and years. We licensed it to Nakamichi. They're still great amps. 1988—US Patent 4752745: Opto-isolated bias circuit for operating push-pull amplifiers in class-A and class-AB modes: This one was optically coupling current sensing to the bias circuitry, which locked it nicely. Typically, bias drifts over time, and with changes in temperature. Even if it's perfect, the amp heats up and things shift. This was a way to look at the current and couple it back to the bias circuit for a constant bias. Nowadays, we just let the amp warm up and settle in. One hour is pretty good, two hours is better. 1990—US Patent 4899387: Active low-frequency acoustic resonance suppressor: [This patent isn't for an amplifier circuit, but for a floorstanding device that canceled out problematic room resonances. You'd set it where a peak was occurring, usually in a corner. It would measure the sound, amplify it, and play it back out of phase, canceling out the resonance—kind of like Bose noise-canceling headphones for your room.] 1994—US Patent 5343166: Efficient high-fidelity audio power amplifier: One of my favorite tricks is to look at what other people do and think creatively. For example, see what happens if you just swap the words voltage and current. There's a Panasonic patent, by Sano, Hirota, et al, where a little class-A amp has its power-supply ground driven by the output of a bigger amp that can swing a lot of voltage. If you switch voltage for current, you have an altogether different beast. With this circuit, you can run a cascoded gain stage at low voltage, but at high current through a separate power supply. Then, you can bias the gain stages at enormous currents. Bipolar outputs usually have a sweet spot around 100mA or so, but MOSFETs just keep getting more linear with higher-bias currents. MOSFETs love current. For example, a 100W class-A amp would need a 5A peak output into 8 ohms, so you'd normally bias it at 2.5A. Here, you could bias it at 10 or 15A. The distortion is inversely proportional to bias, so 10 times the bias gives roughly 1/10 the distortion. There's no need for feedback—you get great performance without any. It's a cute idea. Technics made a few [of their version] but it didn't seem to go very far. This is one that I've got, still waiting to be turned into product. 1994—US Patent 5376899: Amplifier with gain stages coupled for differential error correction: This is Supersymmetry, which was the basis for the X series of amplifiers. It's a way of connecting two matched, balanced amplifiers to more effectively cancel out noise and distortion. One of the advantages of balanced circuits is that when the two halves are summed, noise and distortion that are in phase cancel out. This only works to the extent that the noise and distortion are identical in both halves. Rather than trying to totally eliminate noise and distortion, Supersymmetry works to make the noise and distortion in the two legs identical, which is comparatively easy. The two inputs of the balanced circuit are cross-coupled; the noise and distortion created in each half is fed through the other, so that they're more closely matched at the output, and effectively canceled. It's another way of making a very simple circuit work well enough to operate with less feedback—although it's a kind of feedback itself. You may notice that this amplifier was invented before the Aleph 1998 patent, but came out years later. 1998—US Patent 5710522: Amplifier having an active current source: This the Aleph circuit, where the output device is biased to run in single-ended class-A mode. It draws current from the negative rail to the output. One of the reasons I started Pass Labs was because I wanted to go a new direction. When a company is successful, as Threshold was, it limits what you can do, how far you can diverge from successful products. If you do something different every year, no one will buy your products. Pass Labs was a clean slate for me. There was a lot going on with single-ended designs, but it was mostly in the 1–2W region. I discovered that, with the Aleph circuit, I could get a reasonable amount of power before it transitioned into push-pull. The Aleph 0, which actually preceded this patent, was biased to produce 75W in single-ended class-A mode. It was a simple circuit with only three stages. The Aleph 3 was different. It had only two gain stages and was purely a single-ended design, with no transition to push-pull. There were no adjustments of any kind and it was impossible to break. Now, in the X series, we're again using a push-pull output stage that's biased by a single-ended constant-current source, similar to the Aleph 0.

Ovo kaze fikus: Marantz CD73 - contains actually the whole mechanism in it. It is not a mere tray which takes the disc, but the whole ton of metal mechanism of Philips CDM Zero comes out of the player. Very impressive. It looks good, feels good and plays good. God if I could have a SPDIF transport like that !!! But no - the Revox does not have SP/DIF yet. This format was not invented because noone needed external DACS back then before 1985. The Philips TDA 1540 was the DAC chip to have and nobody proposed to build external boxes. I am sure it is possible to extract raw data from the SAA7000 chip and with a little help from additional SAA7220 we could produce SP/DIF but I havent tried it. http://www.lampizator.eu/lampizator/REFERENCES/Revox%20B225/RevoxB225.html
