Using as a Power Amplifier
Turning the dial all the way up to maximum volume has the same effect as jumpering out the volume
POT. The POT cannot be completely jumpered out on Sensation as it can on the ONE.2 and TWO.2
amplifiers.
Dodd Tube Buffer Option
We are delighted to be able to offer the finest buffer made today as an optional upgrade to the
Sensation’s preamp stage. This stage “buffers” the impedance from the source to the amplifier so as to
present a “friendlier” impendence to the speakers. It essentially sorts out impedance mismatches that
prevent the amplifier from efficiently transferring power, which would otherwise degrade the sound.
Most folks agree this results in a fuller, more lively sound that is also cleaner. You don’t need to crank
up the volume to enjoy the benefits of the buffer.
The buffer is a proprietary potted circuit – don’t ask what’s inside. It is the quietest and most musical
that we have ever heard.
The Dodd Buffer in Sensation can be switched on or off from inside the unit (
but only do so when it is
fully turned off and unplugged or else you may hear crackles and pops in your speakers
).
The upgrade is shipped with an excellent JJ 12-AXJ tube that sounds perfectly swell to many of us. But,
you can roll just about any 12v tube that fits. Here are some of the ones we’ve tried (no guarantees):
