The LAB 102 is a precision preamplifier, based on discrete circuitry designed by David Blackmer, establishing a new standard of sonic excellence in electronics. This exacting new standard provides frequency response from 2Hz to 100kHz +0.1dB, a rise time of 0.27 microsecond. , eliminating all possibility of sonic degradation. These preamps are so fast, so clean and so transparent that you don’t even know they are there. It is like plugging your microphone into a “piece of wire with gain”. You will hear clarity and detail that is not available in any other preamp at any price.
