Vintage Analogue meets Modern
Featured: Dirac Live Digital
JBL 4344Mk2 speakers,
Berning Siegfried amplification
BAS member Ken Schwarz will
demonstrate what can be achieved by combining vintage
high-end audio gear with modern digital correction.
Large-format, horn-driven speakers of the 1970s-1990s
produce an effortless and full-range sound, but
can be difficult to position and adjust for low
coloration. Kens using an inexpensive MiniDSP-based
Dirac Live processor to judiciously clean up residual
amplitude and phase errors as well as to provide
a line-level crossover into bi-amped JBL 4344Mk2
speakers. Bass is driven by a Crown PS-400 solid-state
amp, and mid/HF/UHF is driven by a Berning Siegfried
amp, an unusual 10W, single-ended triode, output
transformerless (OTL) design.
Attendees are encouraged to
bring CDs, SACDs, LPs, or Mp3s of music they'd like
to hear in the system.
Refreshments will be provided
