Silkworm Series 500 Preamplifier
Thanks to the dual stage servo loop, there are no capacitors in the signal path from input to output. This yields a linear phase low end which is not achievable with tube preamps or conventionally designed solid-state ones. When used with a good quality microphone (or instrument), the effortless and open low end is immediately noticeable.
When in transformer mode, Silkworm sounds just like Neve 1073LB. This was not intended, it just happened; it has a completely different design approach. In solid state mode, it becomes extremely transparent, resulting in stunning realism. Solid state mode preserves clarity even when extreme equalization is applied. Input transformer assures that the tone is never sterile even at cleanest settings.
Here’s a female vocal recorded through the Silkworm. Output was set to solid state (no transformer). The microphone was a Neumann M149 and the compressor was a Distressor (for a very neutral and coloration free compression). No EQ was used.
Here is a song with acoustic guitar recorded through the Silkworm. Audio Technica ATM4042 and ATM4060 microphones. The vocals were done through the Creamer Plus in pentode mode, solid state output. The mic was Audio Technica ATM4060:
Here’s an acoustic guitar sample recorded first with an EMI Redd 47 preamp (famous for it’s use on Beatles’ records), and then with a Silkworm.
