    Interesting, although if I was in the market for something like that, I'd probably get this Panasonic instead, it's cheaper and adds Bluetooth as well as a pair of speakers:
    Panasonic 80W Wireless Stereo System with CD Player SC-PM700PP-K

    I think the main selling point for Techmoan is the dab+ included.

    Mine is coming hopefully around the 10th or so. I also went ahead and put in my order for the B90 Limited Edition Champagne color. These next few years are going to be great :)

    I noticed in the manual online, it mentions you should not press play on both decks at the same time. I am curious what happens if you do?

    People are receiving them now and the comments on build and sound quality are mostly positive. One mentioned that the volume while using Bluetooth is a little lower. I didn't get a chance to unpack it yet.

    I wonder how many units they have to sell to be profitable, I'm hoping they do good. We might have to have a new forum topic, "The New Boomboxes," there's actually dozens of new releases over the last eight years and they seemingly just keep getting better.

    Not sure of any bad Mojo, i got mine on Friday and had seen unboxing/pictures of nearly 30 by then. The bad mojo sightings on FB may have been those... not into "new" retro?

    But i'm loving mine. Holy crap, the Bass is nice, but it is better louder.

    From what I've seen, it's mostly impatient buyers, which is understandable.

    Just a lot of people on their FB Feed complaining that they haven't received one yet, no complaints about build quality....

    I received mine a few days ago, and I have very mixed feelings about it. Rob Owens worked incredibly hard to bring this radio to market, so I’m trying to express my opinions as respectfully as possible. After using the BB-777 for a few days, I recognize that I am the wrong customer for it, and others may have a considerably higher opinion.

    Positives:

    • With the exception of a wobbly volume knob, the build quality is extremely good.
    • The vintage aesthetic is spot-on.
    • Of all the inputs, the CD player sounds best.
    • Playing it at higher volume levels generally seems to improve the sound.
    • It’s fun - people’s eyes pop when they see it.
    Negatives:

    • It was clearly built to prioritize volume over sound quality. To me, it sounds like a PA speaker.
    • The treble is harsh to my ears.
    • Cassette playback quality is surprisingly poor.
    • The bass and subwoofer controls must be turned all the way up to produce what I consider to be a normal amount of bass (and I’m not a bass guy)
    • Sound quality suffers especially at lower volumes.
    • BumpBoxx has yet to publish meaningful specifications such as RMS, THD, frequency response, or signal-to-noise ratio.
    • The BumpBoxx Facebook community is extremely hostile toward respectful, critical opinions or even honest questions.
    After spending several days with it, I’ve concluded that I’m simply not the right customer for this radio. Loud is not my primary criterion for an audio device. Sound quality matters far more than volume.

    Many BumpBoxx customers will probably love it. It’s huge, fun, and plays extremely loud. For many people, that will ring the bell. For me, unfortunately, it’s a bust.

    I genuinely hope Rob sells a million of them. He’s worked hard to bring this radio to market in the face of personal tragedy and adversity.

    I understand what you're saying about the volume. It's clear it was designed for playing loud. It's not something you would put on your desk and listen to while you're studying. The volume knob is digital, so it goes in steps instead of infinite graduations, so each step is a significant increase.

    Another thing that might interfere with low-volume listening is the static/background noise coming from the outer speakers. It is especially noticeable with classical or jazz, since that type of music contains quiet passages that allow the background noise to be heard.

    In terms of frequency response, I did confirm that the speakers are capable of playing from 50 Hz to 20,000 Hz (or maybe even higher, but I didn't bother testing higher than that). I did this by playing single-frequency tones into the Aux jack, and then measuring the output with my DecibelX app which includes a spectrum analyzer.

    Overall, we need to understand that the Sharp GF777 this box was modeled on was never a hifi device itself. The JVC M90 is a much better sounding box, and Bumpboxx has told me that the upcoming B90 will be modeled around that sound signature.

    What type of music were you listening to on it? And when you say the tape deck is poor, do you mean like the stability/wow & flutter, or the frequency response? Or both?
