Finally, your long-dreamed Vacuum Control Amplifier has been announced by Combak Corporation. CAT-777MKII, its second generation and upgraded model over previous CAT-777 has uncovered its veil．It’s now become available worldwide.
Introduced for the first time at Munich show in May 2010, CAT-777MKII has captured great attention by specialized audio Medias, audiophile around the Europe and many visitors from Countries other than Europe. Designed in combination with our rich and unique technology in addition to our traditional Harmonix resonance control technology by using selected materials, custom made parts such as condenser, transformers, internal wires mentioned fewer here, CAT-777MKII has been raved as the best vacuum control amplifier in Audio Industry today.
The exquisite sound that CAT-777MKII bring out to you may be for the first time in your audio life. Certainly, the sound of rich midrange, crystal clear in high and exceptionally deep base extension will touch and satisfy you.
