Design Concept
• An sonically absolute state of the art unbalanced full preamp,
in an elegantly minimalistic chassis
• Utilising a hybrid (tube & jfet) MC & MM phono section, and an
all tube line section
• Zero negative feedback in both phono & line sections
• Two stage passive RIAA equalization in the phono section
• Extremely low output impedance (~100 ohms) and high current
drive (~10mA) for a tube preamp
• Exceedingly wide bandwidth: 5Hz to 500kHz minimum
• State of the art low noise levels
• Extremely accurate RIAA equalization, and channel matching
• Extremely accurate matching of channel to channel phono RIAA
equalization for superior stereo imaging
• Externally adjustable phono section gain (two positions) to
match low or high output MC/MM cartridges
• Externally adjustable cartridge loading by extra RCA plugs
containing the desired resistance
• Externally adjustable line section gain (two positions) to
better match the SVP-2 to the remainder of your system
• Signal path components choosen for their extreme sonic and
engineering competence
• Hand built in Switzerland after 30 years of intensive
listening oriented design & development

dpa519 monoblock poweramps
(pair) £14,500.00
A new BIG tube
amp—the monoblock dpa519. Our dpa300B amps sound amazing, but
their 18 to 25 watts is not enough for many speakers, and/or
bigger room, so development work is progressing. With a
unique but quite simple circuit topology, and zero negative
feedback, it’s been designed from the ground up to deliver 150
watts of wonderful music into any speaker—and to enjoy working
with such difficult loads as one ohm (!!) Apogee Scintillas,
complex multiway "cones in boxes" such as Wilson's, or full
range electrostatics!
Vacuum State cartridge – stereo
£1,495.00
Vacuum State cartridge – mono
£1,495.00
There are many
brands of cartridges on the market, often at hugely inflated
prices, but as it’s such a difficult job to built something this
intricate, small & precise, most of the brands all come out of a
very small number of specialist facilities. And by far the most
prolific European manufacturer is Benz Micro, right here in
Switzerland. Herr Lukaschek revealed they had some interesting
ideas that hadn’t been put into production, and after testing
some that seemed key, and specifying their very best parts—here,
still wearing a Benz Micro logo, is the first prototype Vacuum
State low output MC cartridge! The most obvious differences over
the top Benz branded models are that (1) it is nude and (2) it
uses a brass structure rather than aluminium. Brass is much more
rigid than Al, and also much denser—both properties resulting in
a cartridge that keeps it’s body still in relation to the music
driven cantilever motion—this in turn produces great dynamics
and very fine macro & micro resolution. Naturally this cartridge
is heavier than an Al bodied one, and needs a relatively high
mass arm, but as many arms need mass added to the cartridge to
balance correctly, this will be easily accommodated. And the
kicker is that with direct purchasing, and direct selling, our
price is well below that normally asked for such a extreme
cartridge!
