More Product Infor:
Manley's most esoteric product is the 300B Preamplifier. This is the first and only preamp to feature these classic tubes. Manley has been designing the 300B into small power amps for many years and have always had great respect for the smooth natural sound of this tube. However, a single 300B provides truly appropriate power and voltage swing for headphones and makes a remarkable line driver. Here is where the impedances are not too low and the power requirements are not too high: ideal for this kind of tube in a single-ended configuration.
Manley combines the historic 300B with another classic, the large octal based 6SL7GT, for the input stage- all triodes running in pure Class A operation. To complement this 'retro' feel, Manley implemented vacuum tube rectification and regulation in the power supply along with plenty of capacity. Manley also developed an additional (and innovative) ripple rejection circuit to filter out power supply noise making this an incredibly low-noise preamplifier - especially critical for headphone users.
Complementing this lovely and rich sounding line-driver is the ALPS audiophile volume control, gold plated RCA connectors, high purity silver wire, mil-spec printed circuit boards with extra thick copper and plating, and custom designed output transformers which Manley winds right in their own magnetics department.
Whether you use headphones or loudspeakers this preamp will deliver the goods and spoil you for any other preamplifier.
