Default Yaqin MC10-T

There is a new model from Yaqin MC10-T and uses four 12AT7 with output still EL34B. How good is the sound of 12AT7 compare to 6N1?

....better. /6,3 v heating of 12AT7 is - short between 4 and 5 pins. Heating wires are between 9 pin and 4 and 5 pins. For 6N1 - 6,3 v between 4 and 5, not for 12 v/

12AT7 covers all HI-FI band, like 6N1P.

No. LF response is set by the circuit, not the valve. 12AT7 works OK up to VHF radio frequencies, so any HF weakness is due to the circuit. 12AT7 can be non-linear, as it was intended for RF mixing, so need to use carefully. If the circuit designer knew what he was doing then it will be fine.
