KR Kronzilla DM MONOBLOCKS

EXCELLENT LIGHTLY USED PAIR WITH ORIGINAL PACKING CRATES.
we are happy to take trade ins, but bear in mind that we are based

HERE IS A BRIEF QUOTE FROM POSITIVE FEEDBACK REVIEW,
we only acquired these because the seller moved, had to change his speakers and then needed new amps, just a couple of hundred hours on the tubes

The resolution is simply world class, on the level with that of the best OTL amps I have heard. Although the Kronzillas let you hear all of the transient details of the music, they don't stop there, because you can also hear the full harmonic bloom of the instruments and their VERY long decay. What is more, these elements emerge within a truly natural perspective—they never run over each another and smear the sound. Hall ambience and acoustic echoes are not only easily heard, but are rendered quite separately from the main sounds. In my experience, only very few amplifiers can walk the kind of line I am attempting to describe. Most fall to one side or the other, either highly analytical or richly harmonic.

The analytical amplifier is often lacking in harmonic structure (i.e., correct timbre) and decay. It resolves to the back of the hall because it gives only a skeletal picture of the music. Instruments are separated in space but not tonally differentiated, and the ultimate effect sounds a bit clinical and cold. On the other side of the line is a sound that is more enticing to many experienced listeners. It is a bit warm (some say "musical"), full of harmonics, and often a bit fat and loose in the bass. Amplifiers that fall into this trap simply trade one type of distortion for another, and the price paid is a lack of the precision that cannot be heard at live, unamplified concerts. This warmth is created by distortion in the low frequencies, and by harmonic smearing, which limits resolution and diminishes clarity when the music gets complicated. Instruments blend together and lose their individuality. With relatively simple music, this kind of sound can be satisfying—at least for a while—but ultimately, the uniformity of sound that these amplifiers create, with all kinds of music, can lead to boredom, or a swing to the other side of the sonic fence.

My point in all of this is that the KR Kronzillas have all of the speed, resolution, and bass control of the best solid state or OTL amps, but retain the tonal and spatial accomplishment of good tube amps, along with a dynamic drive and energy that I haven't heard from any other amplifiers. The origins of their technology are not at all obvious from listening to them. In my opinion, they realize the ideal of the hybrid concept, and have done so in exactly the reverse manner from which I would have expected it to come.
