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 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 series products.
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)
Full isolate with the AC power line
Uses 650W transformers and more than 100,000uf audio grade NOVER capacitors are used to ensure ample and smooth power delivery.
Applies 24 pieces transistors ( in total had 3900W ) to drive the 650W output transformer for 350W AC power output.
Class A PSUs power supply for regenerative drivers . 4 groups US AC outlet , max power output achieve 350W, enough power supply for DACs, preamps and headphone amps (It can't power supply for power amps)
While audio is life , the Power supply is water , Pure water create the wonderful life ,clean power supply reproduce the beautiful sound .
The regenerative power supply like a proprietary electric generator built in the unit.
It can block most disturb from the power line , supply the ultra clean power supply for the audio amps , reproduce the most neutral and analog sound like audio signal for the system and the users.
In the regenerative power supply design, the AC power through the regenerative input transformer , conversion to DC power ,through the class A PSUs power supply for the regenerative wave generator and driver stages .
A balance regenerative regular wave generator produce the ultra low distortion 50Hz wave ,through the balance gain amps and the strong output stages , drive the regenerative transformers produce the clean AC power supply feed to the separate class A PSUs power supply for the L and R channel preamps .
The class A parallel connection PSU has very high input impedance to avoid disturb through the PSU from affecting the signal parts and low output impedance with very fast speed and high linear, it is a very clean power supply.
Audio-gd on the regenerative power supply design points :
1, Through analyzed the AP SYS-2722 , full analog design of the regular wave generator have much lower distortion than the digital generator.
2, Digital drive stages have higher efficiency , but full analog drive stages have much better analog sound like .
3, 400Hz regenerative wave have higher efficiency , 50Hz regenerative wave had much far away the human ears sensitivity area than the 400Hz, boost the sound have much better analog sound like.
Uses all audiophile grade components, including DALE resistors, WIMA caps, custom order NOVER (UK brand) caps, all audiophile grade input & output sockets (Neutrik ) and gold IEC socket. HE-1 all parts of four channels had exact match before install.
