HESCHL - HAL-350 Integrated Amplifier V2 with R2R DAC

Heschl - HAL 350 V2 Integrated Amplifier (Australian Made)

We have to demo the updated second version of Heschl HAL-350 Integrated Amplifier with built in R2R Ladder DAC and now with AES-EBU along with USB and SPDif inputs. Plus you can now fit your own high end power cable rather than use the fixed OEM cable. Please call Terry at GC HiFi on 0419448452 to discuss a demo or to arrange purchase. 

cheers Terry

The locally designed and built high end Heschl Amplifiers are now available for audition on the Gold Coast, please contact us at GC HiFi to arrange a private listening session. We ship Australia and New Zealand wide.

350 watt integrated DAC Stereo Amplifier

• A truely exceptional High-end amplifier which is unequalled in it’s field and pricing.

• A simplicity of design with sophistication of execution where every component has been optimised to deliver the best sound experience.

Teamed with an Exceptional build quality to create a truely dynamic amplifier. Working tirelessly to perfect the synergy to create a truely exception listening experience.

Packed with 350 watts at 8 ohms (600 watts per channel – 4ohms) there is more grunt than you will ever need. With a range of inputs including Aux (RCA), Optical, Coax and USB. Paired with the Bluetooth App for use on your smart phone or tablet (iOS and android) you have everything at your fingertips.

What’s under the hood – HAL 350

Teamed with an Exceptional build quality to create a truely dynamic amplifier. Working tirelessly to perfect the synergy to create a truely exception listening experience.

Packed with 350 watts per channel at 8 ohms ( 600 watts per channel – 4 ohms) there is more grunt than you will ever need. With a range of inputs including Aux (RCA), Optical, Coax and USB. Paired with the Bluetooth Remote Control App for use on your smart phone or tablet (iOS and android) you have everything at your fingertips.

Another key element which sets our amplifier apart from the rest is the integrated DAC. This approach eliminates any DAC miss-match which is a common flaw in many systems. As such we have created a truely exceptional high-end amplifier which is unequalled in it’s field. Through simplicity of design and sophistication of execution, we have ensured every component has been optimised to deliver a ‘sound experience’.  It is a beautiful piece of engineering.

“We have designed our flagship amplifier the HAL-350 from the ground up incorporating a minimalist design philosophy using a synergy of high quality components all individually matched and tuned together as one.”

“The Heschl HAL350 effortlessly drives the most demanding loudspeakers to musical nirvana, be the performance full scale orchestra, high-decibel rock band or string quartet. Exhaustive listening tests at the component and circuit level and not myopic focus on specifications have informed the development of this amplifier. We are proud of the end result.”

DAC Specifications

The Heschl HAL350 incorporates a custom DAC module based on a discrete R-2R sign magnitude DAC design, with FPGA based FIFO buffering/reclocking and custom digital filters, < 1 ps jitter clock generator, with 28-bit resolution so there is headroom, oversampling up to 3.072 Mhz. Up to 24 bit / 384 Khz input from TOSLINK, SPDIF, and USB (via USB to I2S interface board), with isolation on the I2S interface.  The DAC has a low jitter digital controlled oscillator, data is sent though a short FIFO and the FPGA and uC work together to measure incoming bitrate and adjust clock as needed, basically a digital PLL with very fast lock and very slow filtering. So, the DAC itself only need serial data, word clock and bit clock, no master clock is needed, it will sync to whatever you feed it.

Mindblowing Audio

• Optimised for higher wattage requirements
• Stable into any concievable load
• Spectacular with difficult speaker loads
• Designed like a valve amp without the valves and their limitations

Built to Impress

Hand made in Australia from quality components which where painstakingly sourced or if an acceptable component was unavailable we custom designed and manufactured it to our specifications. Quality is the centre of our design.

No Competition

We strived to make a product which is not just quality but also visually impressive to look at and user friendly. It incorporates an app remote control so you can easily switch between inputs and control the volume from the comfort of your favourite chair.
