YAQIN MC-100B KT88 x4 Vacuum Tube Integrated Amplifier
[YAQIN-MC100B]

I have plenty of Tube amplifiers and Tube Preampli, and I found the Yaqin MC10L quite nice and good quality, for sure the EL34 are nice tubes and suitable for a smooth and soft sound, with rich medium bass frequencies and balanced for the entire frequency range.
This MC100 is the first one with KT88, and it's really great, astonishing, I'm really happy with that, and for sure big transformer help a lot in driving bass transients with authority and without uncertainties.
I like his potential power, which result in being prompt in medium bass, but enough thorough on other frequencies.
