Review on 🎶 S.M.S.L AD18 HiFi Audio Stereo Amplifier with Bluetooth 4.2 & Apt-X Support, USB DSP Full Digital Power Amplifier 2.1 for Speaker – Small 80Wx2 Class D Amplifier with Subwoofer Output by Rachel Scott

I've had SMSL for a few weeks now. I hooked it up to my Bose 301 and expected it wouldn't be able to squeeze them hard. The reviews I've seen have said it feeds much smaller bookshelf speakers. let me tell you This is an incredible thing! Not only did it push my 301s, it pushed them BIG! I also have good floorstanding speakers. I almost have a feeling SMSL AD 18 could power them! This device is very durable with excellent build quality. I haven't had any problems with that. It's hard for me to put into words how impressed I am with this little power station! I've been demonstrating it all the time and everyone has been amazed by it and the amazing results! Likewise. Bluetooth is amazing! I cranked the volume up and walked around the house changing songs and volume levels on 2 floors (not counting my basement) end to end top to bottom with no problems! In my photo SMSL is on the left of my PS3 (yes I still play it lol). You will not be disappointed with SMSL AD 18 if you decide to buy it! To update. I hooked it up to my version 10" powered sub. 8" headphone jack on the red side (mono) RCA. Ad18 works great! I let it play some heavy bass to see if the unit gets hot A little warmed up but nothing to worry about I had the phone volume all the way up and the volume on the unit was 20. I think the bass on the unit was 4. The subwoofer was set at about 90Hz And the usual polarity with the subwoofer volume just over a quarter. So far very impressed with this little powerhouse! Update #2 I had an optical AD hooked up to my cable box and it was great. Learn that my Samsung TV has bluetooth and by device I searched and found the AD18 and paired it with no problems. Even better, now I can control the volume with the Samsung remote. I just leave the AD18 on because even though it's connected to my remote connected, it turns off every time I turn off the TV. If I leave it on, I only have to connect creatures to it that are already connected, and that's fine. I'm still impressed by this little power station!
