does Haniwa realize 3D Audio?
Make the output equal the
input! This is the driving philosophy of Haniwa.
The music output at the speaker should be the same
as the input from the recorded media, whether from
a CD player, turntable, or streaming file. Make
the output equal to the input is quite simple from
a philosophy standpoint, but impossible to achieve
in typical component analog system and digital systems.
Haniwa has spent decades
developing a music reproduction system that achieves
this goal with precise timing, phase, and frequency
control that we call Haniwa 3D Audio. We
call it 3D Audio because Haniwa
recreates a precise 3D soundstage in your listening
room so you can get as close as possible to the
Robert Bean, Haniwa Audio,
said hopefully, we will see you on-line or in person.
Our product designer, Dr. Kubo, will be live
on video from Japan, and I will be in Massachusetts.
Building on our past two BAS meetings, we will highlight
the phase coherent Haniwa speaker system. For this
meeting, we will be discussing analog front ends
and other new advancements from Haniwa tone
arm development and the CVC (Current-to-Voltage-Converter).
The Haniwa CVC allows sub-ohm cartridges to work
in any system by creating a current loop on the
cartridge side and using an MM compatible voltage
output on the phono preamp side. You have probably
already seen the article in Stereophile reporting
on this brand-new type of product::
The current loop interacts
with the mechanical loop to produce a very stable
tracking system. Dr. Kubo will be up and awake halfway
around the globe to answer questions about his analog
theories and the CVC from the group.
There is a further detailed
technical explanation here: www.haniwaaudio.com/technology
Here are music samples
you can listen to and / or download before the meeting.
These are high resolution
24/192 PCM WAV files.
They were digitized from LP's using Haniwa's Current
Loop Cartridge (.2 ohm impedance) and CDV Current
to Voltage converter at ~.5 grams of tracking.
The samples are clips from
the following pieces:
BachOrgan_Sample.wav 339MB - to demonstrate
bass reproduction at low frequencies
360MB - to demonstrate spatial and sound stage
in a classical piece
196MB - to demonstrate coherency with close
to ideal step and impulse response curves
594MB - to demonstrate more modern rock music
329MB - to demonstrate spatial and sound stage
in a jazz piece
514MB - to demonstrate spatial and sound stage
in a folk piece
Refreshments will be available
at 3:30 PM.
