The Theater 7 XD amplifier design uses Krell Current Mode technology—fully differential and discrete in the critical gain stages. This results in a highly linear and extended frequency response, well beyond the range of hearing, for smooth effortless highs and tight high impact bass.

The power supply consists of two 787VA toroidal transformers and 160,000uF of capacitance. This is shared among all the channels so all of that power is available to the channels with the most demand.

In real world conditions the left, right, and centre channels require the lion’s share of the power, thus giving the Theater 7 a more effective power supply than other amplifiers that have smaller dedicated power supplies for each channel.

 

Krell. For when compromise simply isn't an option.

Why choose Krell?

Since being founded in 1980, Krell has been at the forefront of audio component innovation. From the ground-breaking KSA-100, the first high power, high current true Class A stereo amplifier to the finest in home theatre processing and amplification, Krell brings American-made quality and design for the finest audio reproduction possible. Their proprietary iBias Class A design means they can produce amplifiers that can run at high current whilst maintaining control of heat generation. An amazing technological feat borne out of Krell’s years of research and development.

Krell’s attention to detail and constant R&D leads to a complete portfolio of products designed and built to perform and last. Whether it’s two-channel stereo or multi-channel home theatre, Krell represents the pinnacle of quality and performance in processing and amplification.

rell iBias Class A amplifiers are the first to deliver the rich musicality of Class A amplifiers combined with the uncompromised dynamics of classic Krell amplifiers, and the efficiency and low power consumption of Class G and H amplifiers.

Because the iBias circuit eliminates crossover distortion, the amplifier is able to resolve more of the detail and microdynamics in even the best analog recordings—simply put, the music ‘breathes’. Whether an iBias amplifier is called on to reproduce the extreme dynamic range of high-resolution digital files, the minute intricacies of a 45-rpm, 180-gram vinyl record, or the complexity of today’s latest blockbuster action film, it does so without altering or abating the music in any way.

The iBias amplifiers’ unprecedented ability to retrieve the subtlest details gives their sound an incredible dimensionality, with an ambient, broad and extraordinarily deep soundstage. As spacious as the sound is, though, the amplifiers are still able to produce pinpoint stereo imaging if the recording calls for it.

It’s all the power and control for which Krell has always been famous, with a level of resolution and musicality in the midrange and treble that has simply never been heard before.

In short, the new patent pending iBias Class A Krell amplifers give today’s audiophiles and home theater fans everything they could possibly want in an amplifier.

Krell XD Technology

Krell’s XD (Xtended Dynamics, Dimensionality & Detail) upgrade for the iBias amplifiers takes an already great sounding amplifier and raises its performance to the next level. XD is a classic example of Krell’s continuous R&D efforts reaping benefits across multiple product lines. During the development of the K-300i Integrated Amplifier we discovered substantial sonic improvements by lowering the output impedance below traditional norms. When applying this technique to our existing line of amplifiers, the improvement was so substantial, it deserved its own, unique designation—XD.

It was no simple matter merely lowering the output impedance. This affects the amplifier’s stability and transient response, so each stage prior to the output stage had to be re-tuned to work optimally with the lower output impedance. This lower output impedance exerts more control over the speaker drivers, and damps out unwanted vibrational modes—allowing a more accurate reproduction of the original signal.
