Impulse buy. Spent like $60. Fosi or something like that brand on Amazon Black Friday. My marantz receiver is so old it does not have Bluetooth and so I would have to plug in my phone into a RCA to 3.5mm (then lightning, now USB-C) to connect to my stereo to play music from my phone. Yes, I have much better formats available, but sometimes you just want to be a DJ and play what you feel like. It has bass and treble knobs so I can just crank the bass when I want to. I tried it out with my Sennheiser headphones and it sounds great and gets much louder than just my iPhone can.

Highly recommended. And replacement tubes are cheap (I am sure I have some vintage ones that will work as they are 5654w) and they should last a long time.
