MONO-AMP 700
Tento monoblok podla recenzii, slov vyrobcu, technických udajov a ceny sa pasuje takmer do roviny "zázraku" . Zaujimalo by ma, ako jeho merania a topologiu vnimajú miestny technici. (PMA, kazzatel a spol.)
THD vs. Power:
The diagram shows the power measurement into an 8Ω load. In contrast to other power amplifiers, distortions remain on a minimal level over the entire power bandwidth.
Fast Fourier Transfer (FFT)
Measurement for a 1kHz sine signal with 50 watts output power into an 8Ω load. All distortion components are below -115dBr and thus over 550,000 times smaller than the music signal.
Noisefloor
The noise measurement reveals how much noise the amplifier produces without a music signal. All noise components are below -160dBr, measured against the achievable output signal of the 700 mono amplifier. Typically this value lies between ca. -110 and -120dBr. Hence the 700 mono amplifier has about 100 times less inherent noise than comparable products.

Cyrill Hammer: For a “solid-state” amplifier design the speed (e.g., bandwidth) of amplification is one of the most important criteria. This speed or bandwidth has nothing to do with the MHz-range frequencies that can be reproduced by such an amplifier; the bandwidth is required to make the “feedback loops” of solid-state designs work properly. “Feedback loops” compare the amplified music signal at the output with the input signal. Due to the fact that the music signal is constantly changing, the time delay (propagation delay) of the amplifier must be zero; otherwise, applying feedback will add timing errors to the music signal. In other words, if the propagation delay is not zero or close to zero the “feedback loop” will be comparing apples at the output to oranges at the input.
Big solid-state amplifiers can have propagation delays of 1–5 microseconds. Now, the period of a 20kHz sine wave is 50 microseconds. Under these conditions such timing errors are significant—and they get even worse for higher frequencies. The Soulution amplifiers work with an overall propagation delay of 5–10 nanoseconds. This is up to 1000 times faster than other amplifiers. The voltage amplification stage—where we apply the most negative feedback—runs at 80MHz bandwidth and has a propagation delay of 1–2 nanoseconds. Since the timing errors of the Soulution amplifiers are negligible, this gives us the opportunity to apply as much negative “feedback” as we need wherever it is required in the amplifier without reducing sonic performance. This is how we can lower distortion to never-before-seen levels.

Myslím,že místní technici nebudou mít zájem odpovídat na dotazy,nebo se mýlím?.Mne by spíše zajímalo jak vnímáte zvuk tohoto zřízení?
