The amplifier arrived safely in the box with all tubes already installed. The box was very carefully prepared and no damages were observed after a long delivering process. The amplifier was already prepared for the EU 220 V voltage and came with a very solid remote control (2 AAA batteries, not included). I tested the bias voltages after switching on the amplifier and resulted in the correct range, I recalibrated several times the bias during the first tests (10 hours up to now) and fluctuactions were limited to 0.1 V approximately. The sound is good, very controlled and quite powerful at low-frequency, less convincing in the mid-high, high-frequency regime. Very detailed and clean. The difference with my vintage Sansui A80 (solid state) is clear although not as striking as expected at the time of writing (different music sources). The earphone output works fine and is quite convincing. I Think it is a decent product and I am globally satisfied with the purchase.
