We are proud to bring the UltraVerve Junior vacuum tube line stage preamplifier to
production.. It features the famous 6SN7 octal vacuum tube, and all vacuum tube
rectification using the 5AW4 octal tube rectifier.
The UltraVerve Junior Preamplifier is built exactly like the UltraVerve Preamplifier, with a
Noble Stereo Potentiometer Volume Control instead of the Stereo Goldpoint Stepped
Attenuator Volume Control. A definite upgrade over the Verve preamplifier and highly
recommended.
We developed this line stage to complement our single ended triode amplifiers. One of the
things we achieved was to design a preamp that did not damage the dynamic quality of the
music. The UltraVerve line stage is a true zero negative feedback Class A design. The octal
tube complement coupled with tube rectification produces a huge, full-bodied soundstage
and an angelically sweet and dynamic midrange. This preamp is just a joy to listen through.
The Verve preamplifier features 100% hand wired point-to-point circuitry in the audio as
well as the power supply circuit. The front panel is heavy duty Mercedes Silver powder coat
with Steel Gray powder coat chassis. It features a soft start turn on circuit for gentle startup.
The design places very little stress on the tube compliment. This assures extremely long
service and sonic life of the tubes. Quality, Value, and Performance, by deHavilland, "Hand
made in California with a passion for sound since 1997"
According to Kara: The octal tubes we employ give you what in "Tube Lore" is described
as "BIG TONE", something you just can't get with nine pin miniature tubes found in most
preamps. 12AX7’s or 6922’s just can't get there. While many companies say that the
simplest circuit is the best, they don’t practice what they preach -- they have miles of
circuitry and solid state regulation everywhere. Our R&D shows that regulated power
supplies can ruin the dynamics and imaging, just like too much feedback does. We spend
more time and money on our filtering and use big, strong 5U4 and 5AW4 tube rectifiers,
because they provide super dynamics. Furthermore, all of our power supply and audio
circuit wiring is point to point, using the best wire available and the best dielectric known to
man -- air. And while others may dress their equipment up with fancy gold or chrome plating
and exotic woods that offer little or no sonic improvement, we prefer to use premium
components and provide you, the listener with affordable, high quality equipment. Our
gear is literally overbuilt to last a lifetime! At deHavilland, we are serious when we say that
we want more listeners to be able to experience the beauty of single-ended vacuum tube
sound, making this type of pre-amplifier available to a much wider range of listeners --
that's our story.
