October 2022 Online + ln-person Meeting Notice

DATE: Sunday, October 30th, 2022, 2-4 PM Eastern /Boston time
          (NOTE DATE & TIME )

LOCATION: KUBOTEK, USA Inc. Marlborough MA and on ZOOM

FEATURED GUEST: Dr. Tetsuo Kubo & US President Bob Bean - Haniwa Audio,

TOPIC: 3D Audio & Subwoofer

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 wth precise timing, phase, and frequency control that we call Ha niwa 3D Audio. We call it ”3D Audio” because Haniwa recreates a precise SD soundstage in your listening room so you can get as close as possible to the original performance.

KUBOTEK recently added a true subwoofer to continue its expansion into low-end realism.

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 l will be in Massachusetts. Building on our past three 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:

www.stereophile.com/content/analog-corner-310-haniwa-hctr-co-mkii-phono-cartridge-sw1x-lpu-i-phono-preamplifier-page-2

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."

Download Audio Samples
(these samples are all now hosted here on the BAS website)

These are all high resolution 24/192 PCM wav files. These files were digitized from LPs using Haniwa’s Current Loop Cartridge (0.2-ohm impedance) and CVC current to voltage converter at ~.5 grams of tracking.

The samples are clips from the following pieces:

1 BachOrgan_Sample.wav  339MB - to demonstrate bass reproduction at low frequencies

2_TheFirebird_Sample.wav  360MB - to demonstrate spatial and sound stage in a classical piece

3_DrumRecord_Sample.wav  196MB - to demonstrate coherency with close to ideal step and impulse response curves

4_JohnCougar_A_Sample.wav  594MB - to demonstrate more modern rock music reproduction

5_Waterboy_A1_Sample.wav  329MB - to demonstrate spatial and sound stage in a jazz piece

6_TheWeavers_B2_Sample.wav  514MB - to demonstrate spatial and sound stage in a folk piece

Refreshments will be available at 3:30 PM.
