the amplifier in order to avoid unwanted sudden volume surprises when you are ready to enjoy your music again. You now have
successfully installed your new TIGRIS amplifier, enjoy and happy listening!
The following chapters include more in-depth coverage of technical issues and explain the advanced features - but if you’re impatient,
go ahead and enjoy the music now! Changing the Pentode / Triode switches or the Negative Feedback selector is self-explanatory
and will have immediate sonic effects - you should read up on it eventually, but you may postpone it for the moment.
Even though every Mesa amplifier undergoes a burn-in at the factory prior to shipping, a complete burn-in of all the internal compo-
nents and the tubes will take about 100 hours. You may notice a slow and continuous improvement of the sound until this mechanical/
electrical burn-in is complete. Elevated playback levels will not accelerate this process. However, you may opt to set a CD on endless
repeat during absent periods from home to hasten break-in while you are away from the system.
Break-in is equally necessary and noticeable with new speakers where the physical back-and-forth motion of the drivers softens the
rubber surrounds to their appropriate compliance. Some audiophiles go as far as demagnetizing their systems periodically by using
specially encoded Cds, holding that a system builds up an electromagnetic charge over time that interferes with optimum perfor-
mance. Many parameters in the High-End industry are still not fully understood. Certain cause-effect relationships, even though
established, cannot be fully explained yet. This creates an atmosphere where scientific reason and mumbo-jumbo combine to ad-
dress, and sometimes exploit, our desire for ever greater performance and our ignorance in electronic matters. It is important to use
common sense and to trust your own ears. If you can’t hear the difference, or if the difference is too negligible to matter to you, don’t
spend your hard-earned funds.
We recommend to evaluate power cords, power line conditioners and interconnect/speaker cables by the same standards. Very
often,the magic is not a function of fancy white papers and final funds spent, but a matter of trial-and-error which culminates in a
synergistic effect that exceeds the sum total of the individual parts. The adaptability of the TIGRIS will help you make the most out
of the components you already own!
A: TRIODE / PENTODE SWITCHING – Amongst experienced audiophiles, it is a foregone conclusion that in tubed components, the
choice of tubes, their type and origin, will significantly impact the sound of the component. Direct-heated Triodes, Tetrodes, Pentodes,
6550s, 5881s, EL34s and 84s, Czech, Russian, Chinese... they all have unique sonic signatures, and audiophiles have favorites
based on listening preferences as well as personal theories.
Some of the more advanced tube amplifiers allow the end user to switch between Pentode / Triode or Tetrode / Triode operation. But
this always remains an either/or scenario. And that’s where Tandem-State Imaging differs.
Imagine, for a moment, a plant- or animal breeder who carefully selects and then cross-breeds different species to combine desirable
