Interesting details thanks to MVDude:

I believe this is the same unit made by Taiwan manufacturer Vencer. It's model VD-6800.

I've been searching around. I'm not an electronics expert, so maybe somebody can use this info to go a bit further.


I believe the Brookstone Big Blue Headphone Amplifier is the same as this unit made by Taiwan manufacturer Vencer. [computex.biz]



Here is the FCC page for the Vencer unit. You'll find a manual, photos of the internals, and more. [fccid.io]



Reading numbers off the chips from the FCC photos:



It has a ComTrue CT-5301 Audio SRC Bridge chip. [comtrue-inc.com]



It has a Qualcomm CSR8670 bluetooth chip. [qualcomm.com]



It has a Texas Instruments PCM1803A 103dB SNR Stereo ADC chip. [ti.com]



It has a Texas Instruments PCM5102A 2VRMS DirectPath™, 112dB Audio Stereo DAC with 32-bit, 384kHz PCM Interface. [ti.com]



I'm tempted because I don't need a dac amp, but I've wanted to try one. Normally, the least you can spend for something that isn't junk is around $75, and that would be without an internal battery.

I'm not having any luck finding reviews beyond the 3 customer reviews on Amazon. Although, the 3 reviews on Amazon all seem to be legit.

I've been researching dac amps lately. The consensus seems to be that the headphones are 99% of the sound quality equation and a dac amp might give that last 1% for discerning listeners. They're simply not needed for most people in most situations.

A good practical reason for a dac amp is if your computer system is bleeding radio interference into the audio line, giving you hiss or crackling. A dac amp gets the audio outside your computer case.

Another practical reason is that your system simply does not deliver enough power to drive your headphones (which is unlikely for most consumer grade sets). Frankly, if you have the kind of headphones that need an amp, you probably already know about dac amps and you're not shopping for them at Brookstone.

One good thing about this Brookstone dac amp is that it claims digital volume control. Analog volume controls sometimes have channel imbalance where the left and right stereo channels are not equally loud. Digital volume control avoids that.

He evidently does not, so not answering his question and berating him is not very SD .

Using this as a USB DAC is how you get the high-res audio. The bluetooth receiver just gives this more versatility.

Can we connect a 3.5mm line in? A Q&A says yes but I want confirmation as I have yet to see a pic of the other side of the device.

Skimming the manual says it does have 3.5mm in and 3.5mm out

Good price but I'm concerned with the specs and components. I can't find much detail about this item online.

I thought Bluetooth didn't support high bitrate audio anyways? I'd think it could provide more power yet not a clean source?

Is that an inflated $100 price, did it ever sell for that much?
