HeadRoom Total BitHead
The Total BitHead is a upgrade to the BitHead. That beautiful signal that gets to your earbone has to pass through a lot of electronic bits. It has to go through wire and circuit board traces; it has to go through integrated circuit chips, and a lot of resistors and capacitors. You may not know this (because you may never
have heard super high-fidelity audio systems) but your hearing system has an exquisite ability to let you experience sound. So much so, that on very high end systems

you can almost feel the gravelly moisture at the back of a singers throat. Many of these super-stereos are simple in
design but use parts that cost hundreds, even thousands, of
times more that the parts you find in a typical stereo.
We know because we build $4000 headphone amps; and it's those resistors and caps we put in the Total BitHead. How
much better does it sound? Quite a bit more natural, is really the way you hear it. Listening fatigue vanishes and you are able to listen effortlessly for hours. Cheaper
parts sound grainy and slightly confusing in comparison;

annoying and tiring in the long run. Yes, we use the best
cheap parts we can find in the standard BitHead, but in the
Total version no expenses is spared. Don't bother to spend
the money on this parts upgrade if you have'nt spent money on good headphones first. But if you have, the Total BitHead will provide you years of easy and natural listening
pleasure from your computer as well as from analog sources.

Fot the most part, this parts upgrade is on the Total AirHead page. But there is another difference: the analog
op-amp. At the heart of every AirHead is a quad op-amp that
does the buffering, cross-feed delay, mixing, and output preamp functions. When we performed our listening tests
we found two parts we liked: one was liquid and cheerful,
one was dry and down the middle, both measured very well.
We chose the liquid cheerful one for the AirHead Line.
But when we got to the Total BitHead, where we had control of DA converter and are surrounded by good parts, we decided
to go with the more neutral and articulate part. The quad
op-amp part we use is the Burr-Brown OPA4743.

 

Sounds like just the ticket. Oh yeah! It does.
The result of all this sexy widgetry is near-audiophile
performance on four AAA batteries.
