November 2005 Meeting + Special Video Demo and Comparison on Nov 27
Date: (First Meeting)
Sunday, November 20, 2005
Time: 6:00 PM
Place: Constellation Center, 2nd Floor, 161 1st Street, Cambridge, MA 02141
Featured Guest: Larry Kirn
Topic: New Digital Amplifier
The Nov 20 meeting will be with a high end digital amplifier
company based in Boston, Jam Technologies. The inventor of the new digital
amplifier technology will be among the company representatives at our meeting.
Jam Tech received a great write up in the Aug, 05 issue of VOICE COIL. Their
S/N is outstanding and the sound is comparable to analog A/B amplifiers.
The 'True Fidelity' technology is based on technology superior to Delta-Sigma,
and it eliminates the need for feedback loops. The digital patients also
include a new E-Bridge output configuration that provides better resolution
and an actual 16 bits from a 44.1 sample period.
Larry Kirn (he prefers Herbie) is an organist, recording
engineer, performed in a traveling band for many years, and is reported
to have perfect pitch. He designed the digital amplifier to meet his playing
and recording. He has 15+ patents on his new digital amplifier. The remainder
of his bio is on the link below.
There will a demonstration comparing their digital amplifier
with another brand.
It is just NE of our meeting place at the Volpe Center, near the old Charles
River Dam, and is a re-done brick factory building. 1st Street is a north-south

Special Video Demo/Comparison--State of the Art CRT
Date: (2nd Meeting) Sunday,
November 27, 2005
Time: 6 PM
Place: Home Theater Systems, 957 Worcester Rd, Framingham MA; it is just
off of and parallel to the westbound side of Rte. 9.
Joel Cohen has offered to demo for the BAS a special
viewing and a lecture of what he describes as the best video possible. To
accomplish this task, they have assembled the best front projector, a CRT,
and with their modifications, he's pronounced it as the finest reproduction
possible with today's digital or CRT technology. The basic demo will be
between a factory standard CRT projector and the highly modified version
that they sell new as a Crystal View CV-1 and remanufactured as a HI-REZ
projector. They also sell the modified assemblies to individuals so they
can update their existing projectors. He can also discuss other types of
projectors and may set up one or more for comparison. The main source will
be a professional D-5, full-bandwidth, uncompressed format, HDTV deck with
many good movie excerpts and broadcast items. There will also be conventional
sources, scaled up. It is an excellent way to "get calibrated"
with the very best images that can be produced now and in the foreseeable
