The GoldMikeMK2 is the result of all our experience and knowledge from its successful predecessor and represents an improved, more flexible and, more modern version.
We have added technologies that have already proven to provide superior tonal results in other SPL products. For example, the instrument input is designed around a class A impedance converter which premiered in the SPL GainStation.
A significant contribution to the success of the predecessor was
the hybrid preamplifier concept. It combines transistor and tube preamplifier stages and specifically utilizes their technological and sonic advantages: The efficiency and low noise of a discrete transistor stage is enriched with musical coloration of a tube stage.
The transistor stage is composed of single transistors in a class A design. The circuitry is fully discrete, and each transistor is completely optimized for its specific task. You will not find any IC�s in this preamplifier stage because they cannot be optimized for this specific application to the degree we at SPL aim for. This all new discrete class A transistor stage is a genuine innovation in the entire preamplifier market at this price level.
The degree of tube pre-amplification is no longer the fixed +6
dB value of its predecessor. The GoldMikeMK2 sports the selection of three different tube pre-amplifications: +6 dB remains the standard complemented by +12 dB and +18 dB. This allows creative variety with the tube saturation and limiting effects.
We have also added an extra setting to the popular Flair circuitry to give more flexibility to the presence improvement.
Because the GoldMikeMK2 is a dual channel preamplifier,
its channel separation is of fundamental importance for the
stereo image. Therefore the print-board layout is symmetrically
mirrored around the power supply in the center from channel 1 to channel 2. This results in an identical signal flow to supporting a naturally balanced stereo image. Additionally the print-board provides extra-large ground areas maximizing the shielding against crosstalk and interference.
