    • Posted to an Australian car audio forum on 14 Aug 2005 by "golf_bht": "You might want to look at milbert 235 as well. I use it on bumpy road in Bangkok for 17 years and it is still in working condition. Along the line I have gone through 1 set of tubes due to normal mantainance... I personally never heard anything better than milbert... so for the $$$ milbert have the longest service life and the best sounding amp I ever own. Their might be something better on the market but I just haven't discover it yet."

    • The BaM-235ab coupled with audiophile gear and high efficiency speakers can be very revealing. It is not kind of, sort of, maybe sometimes, or slightly better, but the improvement is large and immediately apparent. Veils vanish and things not previously heard leap out from the music: The ambience, the many nuances and intricacies, the breaths, sighs and shimmers all become audibly apparent. And you feel the emotion.

    Drumbeats that were perhaps homogenous thuds in SPL-competition systems are transformed, in that the type of drum sticks, the sticking or playing style, and even the drum head material itself becomes discernible. New layers are revealed. Duet voices become independently distinguishable and harmonious, instead of blurred. A woman's voice in a recording you've heard many times can suddenly make the hairs on the back of your neck stand on end. That's the kind of resolution, detail and emotional impact which you can routinely expect from the BaM-235. In any system, the BaM-235 helps you feel music, and that is priceless.
