Review on 🎶 Nobsound MS-10D MKIII HiFi Bluetooth Tube Power Amplifier Stereo Subwoofer Amp USB/Optical/Coaxial by Faten Teller

I really wanted to like this amp. But not so much. There are many reasons I chose this amp including the subwoofer pre out and this was the first disappointment. The subwoofer pre-out doesn't adjust the volume, which is a big problem as you usually want the subwoofer more than an arm's length away. Then a soft hiss. I've read that this can go away over time, but just to check that I was on my audio connection I switched to a digital optical input and it doesn't work at all. Let's face it, one of the reasons you buy an amp like this is the look of the tubes. Well, one of them is noticeably darker than the other three. Overall the sound is pleasant, fairly clean highs and normal mids, but the lows are sorely lacking. I will try another amp and decide to keep this one based on this comparison but I think this one will go home.
