Non- feedback ACSS analog output stage.
Total applied 12 pcs exact matching 150W transistors ( In total 1800W ) as the output stages and PSU stages for implement large class A output power .
Uses three R-core transformers (In total 135W ) separate power supplies for the digital control components, right and left channels.
More than 55,000uf audio grade NOVER capacitors are used to ensure ample and smooth power delivery.
A total of 9 groups of PSU's for dedicated DC supply.
Uses most Hi-end grade parts and exactly matched transistors, OCC wires.
Four-channel 100 steps digitally controlled relay-based volume control avoids channel imbalance and improves sound quality .
Supper Exponential Volume Characteristic, easy match the volume with very high headphone / speaker without change the gain mode.
20DB gain can drive the low sensitivity headphone very well.
5 groups input: RCA X2, XLR X2, ACSS X1
Preamp output : XLR / RCA / ACSS
Headphone amp output: 4pins XLR X1 / 3pins XLR X2 / 6.3MM X1
1,Master 9 is a pure class A amp, covering the vents is not advised.
2, Master 9 has extremely high fidelity; its SQ is neutral. It can show how good or how bad a recording or source is , and must be given to matching suitable power and signal cables.
3, It is better not to stack gear, if it's necessary to stack the Master 9 on top of other gear, place a peice of paper or other insulating material on top of the other gear, as the Master 9 has conductive aluminium feet.
A review of our preamp and power amp from John Darko.

Radik from Germany:
I'm listening to the Reference 7.1 and the Master 8 since 3 days now - and I'm BLOWN AWAY!!! I had many good audio gear in my short life but I never heard something like that - your stuff is a genius work!!! THANK YOU A LOT!! The room where the instruments are placed in is perfect (reverb and the atmosphere!!) and the soundstage is really homogenous! BUT ABOVE ALL OF THIS IS NATURALITY!!! - the voices and instruments sound very realistic and I know what it means, because I spend much time in recording studios (according to my profession). I'll write you next days more impressions after the Burn In...
