” Op-amp rolling is very popular among audiophiles and the Lycan encourages that tradition. The sonic characteristic of the Lycan changes when different op-amps are used. Its open frame design and gold plated DIP socket make op-amp rolling with the Lycan fun and easy. The SS4 op-amp was sent to Nathan and me when it was first launched but up to now I never had the possibility to try it out. The SS5 compared to the Gen 4 SS op-amp requires less voltage and current. That means peak performance can be reached using less power. There is no sonic difference between adopting one unit of dual SS op-amp and 2 units of single SS op-amps. Gen 5’s cascade output stage is the result of over 10 years of research and five generations of designs. According to Burson, its sonic signature is the most refined we ever created. Burson also just launched the V5i just last week but it hasn’t reached us yet.”

” DAC80 performed remarkably on this track, a clear notch above what I was used to hearing. During the performance there were keys being hit rather hard on the piano, resulting in a sound bordering on angry and certainly not a pretty tinkle on the ivories. But the tonality presented through the DAC80 was smooth but still revealing of the subtle imperfections in the notes that were hammered on by the pianist compared to the sweetness of the gentler notes. The DAC80 held back any sibilance or exaggeration to the middle-highs.”

” Essentially, current mode acts as it sounds like it acts: the signal is amplified by modulating the current rather than the voltage. Current and voltage are not exactly strange bedfellows, their relationship is forged in Ohm’s law, and the resultant current mode amplifier creates an inherently low distortion and wide bandwidth design. Current mode is a very common amp design in high-speed communications and video processing. The CMA800R features an additional voltage-controlled current source and a current amplifier in front of a more traditional Class A output stage, but creating those two amplifier stages requires a low-impedance negative feedback circuit that reacts a couple of orders of magnitude faster than conventional voltage mode amp designs. In addition, the amplifier’s slew rate achieves a linear increase as input signal amplitude increases, in direct proportion to the input signal amplitude. When receiving a high amplitude signal, a current mode’s amplifier’s slew rate is much faster than traditional voltage mode devices, eliminating intermodulation distortion and ensuring a high amplitude signal, with an extremely wide linear bandwidth and an almost distortion free realistic playback.”
