Monoprice Tube Amp with Bluetooth 25-Watt Stereo Hybrid: Reviewed!

You may think that tube amps are outdated by decades, especially in an age where everything is digital. However, when this old-school mechanical amplifier has been fused with some of the technologies today, like Bluetooth, you have an impending comeback.

Digital music can be lossy at times which makes it lose some of the old day’s deep and warm music. The solution that Monoprice came about was to use tube preamplifiers to bring back those qualities that seem to be lacking in today’s music.

Monoprice is already known for making one of the best 5-watt tube amps (we rank the 611815 as the best tube amp under $300)and this Monoprice tube amp carries on that tradition.

Retro Style With Modern Features

The Monoprice Tube Amp is a hybrid system that combines the nostalgically warm sound of a preamp with the clarity and power of a 25-watt power amp. Throw in Bluetooth connectivity and other unique features and you got a system that will send you back to memories lane using a wireless stream.

Sporting a minimalist retro look, this instrument has a mixture of the old and the new. Exposed vacuum tubes encased in aluminum cages gives off a warm glow when the device is turned on. While, its black panels, chrome accents and lighted VU meter further enhances its old-school feel.

If you are unfamiliar with vacuum tubes, they were the ones used before modern transistor amplifiers. You can say that they are more “mechanical” when boosting signals and powering speakers compared to the transistors that uses electrical signals. Audiophiles prefer their more natural and warmer sound that is generated by its mechanical operation.

Here is a really thorough review from Z Reviews:

Here is a summary of all the nice features that this device has:

Overall, this is probably one of the best tube stereo amplifiers that we got our hands into. Its retro look and clean finish exudes a classical look that will surely be a nice addition into your living room or office. The sound quality is just phenomenal, that you wouldn’t think it only cost a few hundred dollars.

However, despite all these positive things about this amp, it also has some weak points. Below are its pros and cons:


  • Very affordable; it’s a great bargain considering its performance and many features
  • Vintage style has a nostalgic appeal. Probably, one of the best ways to enjoy your old tracks
  • Sound quality is as good as it gets; it’s only below those pricier vacuum tubes for audiophiles
  • Bluetooth connectivity is a grand slam, especially now that everything is digital


  • Low-end feedback can be experienced during the song’s quieter moments. But, this can be resolved by using the RCA jacks on the rear
  • Only plugs in 110V outlets

Experiencing the Monoprice Tube Amp will make you think that the future of music may well lie on hybrid systems, such as this one. It has conveniently combined what we loved on both the spectrum of the old and new trends in a portable music player.

  1. Hello Jarsh, nice review – short and concise. What speakers, sources and tracks did you use for your listening tests?


  2. I feel the same as you, and like any hifi guy I rolled the tubes with a set from the Canadian tube store. It’s marginally better (noticeably in the detail). The solid state amp is clean which is a surprise, and it drives my Canton pedestal mount speakers. It truly opens the sound more than any amp I’ve used. The voices and instruments are separated giving you live sound. $200 is a bargain from Monoprice, and highly recommended. My other amps/receivers are Marantz.
