Pretty sure that's trolling because I can't imagine anybody buying a tube amplifier and not knowing this.

The most hilarious thing about this product is that it hawks connecting via Bluetooth, which obviously offsets/ruins any "benefit" from the tube stage.

I'm not. My turntable has a preamp, and I have to set it to "line out." From there it's RCA cables from my turntable to the Line in RCA jacks, then the line out goes to a pair for studio monitors I...

The good news is, if you're listening on Klipsch ProMedia, then the amp you use doesn't matter. You can feed it with a hamster wheel, some wire, and an iron nail. It'll all sound the same.

Relax, maestro. We’re not tuning a million-dollar listening room, just figuring out how to get decent sound out of $100 speakers that's broken here. LOL

Neat little unit. Class D amp with a TPA3221 chip quoting 100 watts per channel. Would be a simple way to power a pair of bookshelf speakers.

By most reports, these are garbage. Uneven frequency response. Lots of distortion. The good news is, the amp stage is solid state. The bad news is, the preamp stage is tubesa, and it's poorly...

The tubes need to get warm to work. If it’s not warm, it’s probably broken
