I just installed my new home. I didn't wear thread cloth, just wanted to listen to music. The living room is 20 square meters, facing the main speaker of hivi M6, and nothing else is needed, plus a courage machine. It is recommended that you match transistor pure class A power amplifier. The transistor power amplifier at this price has great advantages over the electron tube power amplifier. I recommend two class A amplifiers: 1, CEC AMP-3800 2 and Tianyi AD-3. The former is an imported power amplifier with power of 64 * 2 (8 Ω) and 85 * 2 (4 Ω), which is smaller. The latter is the domestic power of 150 * 2(8ω)28KG, and its volume is about 6K. It should go well with your suitcase. Have a good fever!
