Speakers to big room

I have tried Leben and Almarro monoblocks and I like it the best with powerfull and very clean amp.Maybee I should try them with MasterSound Caesar 300B as Jeff Day mentioned in review http://positive-feedback.com/Issue49/tannoy.htm.

I know tube amps are popular with high sensitivity designs like those, but I wonder if insufficient damping could be the culprit? Tube amps have higher output impedance which results in lower damping. Have you ever tried a SS amp with very high damping factor for comparison? I would expect much different sound in that larger drivers often benefit from higher damping resulting in cleaner and more articulate bass. Maybe better overall, maybe not.

A good Icepower Class D amp might be interesting to try with those Tannoys for that. Since they are high efficiency, you may not need many watts, just current, damping factor, and higher input impedance also if you are also using a tube pre-amp. BEl Canto ref500m monoblocks come to mind. These have a good rep and make improvements on stock Icepower power supplies and input impedance for use with tube pre-amps. I use larger BC ref1000m monoblocs with my lower efficiency OHM Walsh 5s, which also use a larger driver tha benefits from higher current and damping.

O,here is specifications for my amp,I think you can't get anything better then this($30k),this amp is state of the art product.

Music is like Poetry. It is very abstract and everybody can feel something quite else when hearing it. Emotions from Music express themselves in us like invisible poetic lines. By means of our amplifier you can fully devote yourself to music Poetry, experience non-specifiable feelings. This amplifier has such extraordinary abilities that it literally excels in this “poetical” performance. That´s why we called it “LYRIC”.

During years of successful experiments with new technologies concerning analog signal processing we discovered what topology and physical properties of circuits are important for clean, natural and true sound reproduction. The output is the SIL technology in which these pieces of knowledge touch the very end of physical borders of capabilities of today´s component parts and production technologies. The LYRIC is a unique product of the highest possible category not only from the point of view of utility and technical characteristics but also as to high reliability and durability.

This amplifier reproduces a really clean and natural sound, perfectly controlled with a real dynamics and an excellent resolution of even the finest details. Its distinct characteristics is the precise depth of focus of all the dynamic peaks which don´t mask even the most silent instruments in the background of the record.

The reproduction is always full of emotions and pleasure and it is not tiring even during a long-term listening. On the contrary, when choosing a suitable genre, it works positively on the listener´s psyche and so it supports maximally healing effects of music. Thanks to the SIL technology the sound is not changed at all and it keeps all the described characteristics for very low, middle and high loudness’s.

These characteristics wouldn´t be fully used with a standard quality signal source. That´s why the amplifier contains an equally perfect D/A convertor which corrects jitter signals on the top level and in that way it needs above all data read in an errorless manner, which is only done well by the newest CD transports.

The experience with such a high amp and D/A technology shows that it is possible to get really top performance even from CD format which is comparable with high resolution formats. Even output sound from digital radios surprises the listeners.
The advantage of the SIL revolutionary technology comes to light above all during long-time hearing, best on precise loudspeakers capable of high resolution. They are commented upon too large drawing of records disadvantages, though, but after some experience with our technology you find out that huge majority of those disadvantages surprisingly disappears in full. Come and listen, it is impossible to describe the advantages of this new technology in words.

he main aim of the development was maximal suppression of all non-harmonic distortions of music signal. These distortions are typical mainly for transistor amplifiers and they have the greatest negative influence on naturalness of music signal. They can´t be seen from standard measured parameters because they come to existence through unstable linearity of the amp which changes according to momentary process conditions. They implicate aggressiveness, synthetic sound and sound blending. That´s why there are still lots of fans of tube amps which can be good in some aspects but on the other hand they have other probably unsolvable disadvantages.

Other problems are dynamics and perfect depths of focus of the signal in the whole audio frequency range. Managing this problem demands use of our SIL technology. Using of another construction leads, according to audio tests, either to emerging of unnatural non-harmonic distortions or sound of instruments or voice has poorer colour palette, details are missing, which implicates lower level of emotional perception.

Our SIL technology is a specific combination of material, spatial and circuit solution of amp stages using the newest sorts of transistors. When thinking of circuits an extra topology is in question which holds good linearity of audio signals without using standard whole feedbacks. The Linearity is ensured by complicated handling of working conditions of each signal transistor so that it only uses the linear part of its working characteristics. Resting non-linearity is compensated by addition with mirror-inverted non-linearity. The result is that they annul each other.
The most important advantage of this SIL ( STABLE * IMMUNE * LINEARITY ) is above all the stable amp Linearity. It is absolutely Stable and Immune against outer and inner influences. The amp distortion does not change according signal complicacy, it does not even react to high frequency disturbance nor to disturbance coming through power supply, nor to impedance and complicacy of loudspeakers, nor to momentary loudness of playback. These are unusual characteristics, which bring about unbelievable sound experience in the outcome. Having experienced this technology for a longer time, no comeback is possible. Euphoria from this new quality does not devaluate, on the contrary it rises step by step because the listener discovers more and more benefits by this technology. The Music will never cease to entertain you.
