What's new in the HE-1 LE:
The first generation HE-1
released in 2015 years.
Since 2016 years , some lot
customers asked me , do you have plan to upgrade HE-1?
The analog circuits design is
slower develop compare to the digital design. Especial the
excellent design.
In our product upgrade policy,
we don't want declare the upgrade edition but just change the
chassis or re-arrange the inside , no real upgrade on the design and
sound quality.
Since the first generation
Master-1 released,
we have not change its design , we always like to upgrade the
design but we can't .
After 9 years, in the 2021
years we spent the long term test and audition, now we are release the
new version, it apply the perfect layout technology, sound
quality improve obviously, better detail and dynamic but more analog
sound, no harsh anymore, and the functions also upgrade:
1, It has two gain modes for
user select to match with the different gain power amps.
2, It has double volume control
can match well with the different output level sources.
3, The new design apply the
same board of Left and Right channels that make the design exact same,that
we can measure and match the boards for assemble in the one unit to
ensure the consistency .
What's different between HE-1 LE and HE-1 MK2:
The HE-1 LE and HE-1 MK2 have share
the exact same analog board. The most different is the HE-1 MK2 has built
in regenerate power supply that can filter all power line interrupt,
feed the most clean power to the analog boards .
The HE-1 LE has built in the linear power
supply , benefit from the built in pure class A PSUs that can offer
the quite clean power to the analog boards.
If customer want the best sound quality,
choice the HE-1 MK2.

If customer want to get the best rate
of performance and price, or already own the good enough external
power processor, choice the HE-1 LE .
HE-1 LE summarize :
Fully balanced class A design built by discrete analog stages without any OPA or coupling caps in the signal channels.
Non- feedback ACSS analog output stage.
Uses three R-core transformers (In total 145W ) and more than36,000uf audio grade NOVER capacitors are used to ensure
ample and smooth power delivery.
4 group class A PSUs power supply for Left and Right
audio signal amps .
Four-channel 100 steps digitally controlled relay-based volume
control avoids channel imbalance and improves sound quality.
Four-channel 9 steps digital controller relay-based pre-volume control
can control the source input level from 0DB (Bypass) to -8DB.
Two gain modes, high gain has 16DB and low gain has 6DB, which
is more flexibility for the different gain power amp .
5 analog inputs:
RCA X2, XLR X2, ACSS X1 ( Even with RCA or XLR inputs, the output
still had ACSS aviable)
3 outputs:
XLR / RCA / ACSS (ACSS and XLR/RCA have the separate output
circuit design so they can connect 3 units power amp
simultaneously)
