A few possible points of interest for CRBN owners.
Steve Guttenberg of CNET and Sterophile has stated time and again that the best sound he's gotten from his Audeze headphones is from a Mal Valve Head Amp
Three headphone amplifier. After years of development Mal Valve has released the 4th iteration of the Head Amp Three as well as two new headphone amplifiers:
the new Mal Valve Head Amp One and their new top reference, the Mal Valve Head Amp Five...a headphone amplifier like no other. We are stocking units and
are proud to be handling the US and Canada on their behalf. Later this year, Mal Valve will also launch their electrostatic headphone, which is in its fifth prototype
over even more years. We have been so impressed with everything Mal Valve, that we will also be carrying their sources, amplification, loudspeakers and turntable. (everyone should hear magnetostatic bass and midrange coupled to an electrostatic tweeter.) Feel free to come look at our
site for further information.
Regarding the Head Amps;
All three amplifiers drive drive Stax (with the Stax Pro Output) and other ESL headphones with independent outputs. They are also unique in their ability to adjust
the polarization voltage on the fly. This has been a great tool for squeezing out the best from all types of ESL cans. They also drive
dynamic cans, planars and in the case of the new Head Amp One and the Head Amp Five, the RAAL SR1A. The Mal Valve Three v4 is also a phenomenal
fully balanced preamplifier. The Head Amp One with the addition of optional outboard transformers is a fantastic stereo amplifier (each of the output transformers
weighs in excess of 45 pounds...no expense was spared in their design). The Five, is an integrated amplifier and a fully balanced preamplifier. The headphone driving
aspects of the Head Amp One and Five are an improvement on the Head Amp Three V.4 (they are a new OTL circuit) The Head Amp Five gives the user the option
of powering the headphones via the OTL circuit or via the onboard coupled transformers. The Head Amp Five has 2400v on the rails. One can drive even the
most stubborn electrostats with ease. The same is true of any dynamic or planar headphones. These amps will power even those headphones with the most insensitive
specs. Lastly each amplifier allows you to save the settings for your favorite cans. The One and Five can use any iteration of KT tubes, (KT66, KT88, KT90,, KT100, KT120,
KT150 and the new KT170 (which is the finest KT tube we've ever heard...the KT170 is like a great singled ended tube on steroids.)
I hope you can get a listen to these very special amplifiers. Below are pics of the Head Amp One (front and back) the Head Amp One's Head Driver, The Head Amp
Three V.4 and the Head Amp Five.
