Would anyone lucky enough to have both care to comment on the comparative sound qualities. I intend to buy one or the other for my daughters birthday - but not sure which way to jump.

Radio sounds very good but is mono, Boom sounds better for a number of reasons.

Boom audio advantages over Radio:
- stereo
- larger enclosure
- add a sub if desired
- audio adjustments (bass, treble)
- StereoXL (selectable DSP)

Actually I believe the Radio has a larger enclosure volume per speaker than the Boom. This helps compensate for having only one speaker in the bass department.

That is true.

but is the enclosure shared for both speakers, or separate?

Boom has 2 woofers, 2 tweeters. The woofers have a shared back cavity. The tweeters are independent.

Radio has 1 woofer and 1 tweeter. Again, the tweeter has its own back cavity.

dean, your msg looks cutoff but glad to see you posting!

i would posit that a shared enclosure is in fact bigger in use than the sbradios, b/c even though the boom has two speakers, they both use the one enclosure.

Yeah, it was cut off, but I was basically saying what Caleb said.

I'm very curious as to the applicability of this paper to the Radio. Were the same type of design and DSP ideas used in the Radio? I understand that the StereoXL stuff and the subwoofer circuitry won't be there, but does the Radio use the same DAC, crossover, bi-amping, and separate headphone DAC?

Thanks!
George

It uses a single stereo DAC, therefore it does not do the subwoofer mode. It does do the same crossover and bi-amping, which is one of the most critical parts IMO.

So does the second DAC in the Boom have optimizations for headphone listening that are not present in the Radio? I'm curious as to how well the Radio will work for headphone listening, without an external headphone amp. Of course I guess I could just go home where the Radio is waiting for me, and just listen for myself ;)

Thanks!

Sorry, I should have been clear on that. The DAC used in Radio has a headphone amplifier built-in. So, headphone usage is just dandy. I use it every night that way. Low noise floor & very clean output. No need to worry.

Thanks for the clarification. I did a little headphone listening last night with Sony MDR-V6s and it sounded really, really nice. Just low I'm listening with my Westone 3s, which are pretty susceptible to noise, and it is pretty good on them too. At first I thought it was a little hissy at low volumes, but I think that is recording dependent.

Caleb, you and your team have every right to be proud of the work you did on the sound on this thing. I'm totally, completely blown away by the sound. I don't think it's a perfect device, but I have absolutely no qualms with the sound quality and quantity. Great job!!
