Passive pre-amplifiers do not amplify the musical signal. Their purpose is to allow selection and attenuation of two or more inputs without - crucially - leaving any imprint whatsoever on the musical signal. At Musical Laboratory* they have been able to approach this ideal through the clever application of a classic, ultra minimalist circuit whereby the musical signal passes through just one audio resistor from the input to the output. With Revision 2.3 they completely rewired the device using their proprietary Silver Gold foils, to give a natural heft to instruments and vocals, as well as deeper bass extension. We at Sounds Of Silence have never heard a passive pre-amp we liked until NOW! This has the dynamics, the detail, the PACE that was always lost with other passive devices. We are currently sold out of all Paeonia's but more are shipping by months end, direct from Luxenburg. Place your order now. Call SOS at 603-888-5104 for more information.
