The HE series products had the
longest term of design and test in audio-gd history . Even though audio-gd
had release the regenerative power supply products since 2006, and Mr.
Kingwa had publish the article in the <Radio & TV> magazine explain
the technology detail .
The HE series products had finished
the design in the New Year of 2014 , we were plan to release
them in the date of audio-gd 10 anniversary , but for got
the best sound quality and performance, we have even 3 times
change the full design for made the compare, and compare different power frequency
and voltage, create the longest design term record.
The HE series products have better detail
and dynamic reproduce ,blacker backstage ,better focus and
larger sound stage , but the sound is better analog .
The right saddle must is set on the right
horse ,if you had not enough good system units, and had not
enough cable match experiences, don't waste the money on HE
Please note the HE series products are upgrade
from Master series, even though the price had a big rate
increased but the sound quality had not same rate improved.
Audio-gd products had
design and test based on the AP SYS-2722 (The top-drawer
professional equipment in world)
Built in regenerative power supply
Separate class A PSUs power supply for regenerative drivers and
audio signal amps .
Uses 6 unit transformers (In total 2400W ) and more than 280,000uf audio grade capacitors are used to ensure
ample and smooth power delivery.
Fully balanced class A
