My new 7 Channel PA for Lsi Speakers

Posts: 40
Gday everyone, I have been on a bit of journey to improve the sound quality on my Lsi system and interested in your point of view.
I have Lsi15's, LsiC and four LsiFX speakers.
I started off with an Onkyo 875, than purchased a NAD T973, 7x140@8ohms, 7x280@4ohms but I still felt I was missing something.
I have just ordered a new 7 channel PA and it should arrive next week, just wondering what you think of the specs, I guess I should have asked this before I ordered but I got a great deal and had a credit with the store.
I am using HT bypass on my Cambridge Audio 840A for 2 channel listening.
The specs and description are as follows, its an Ozi made product, its a new model. The previous model was very popular here in Australia.
Elektra Theatron HD 7 Channel Power Amplifier
The NEW Elektra Theatron HD is a high performance 7 Channel power amplifier designed specifically for both Stereo Music and Home Theatre Audio reproduction.
The power supply plays a significant part sound quality. Starting with our transformers we use extensive electrical and magnetic shielding to keep radiated interference out. Along with this the transformer is potted in encapsulation to eliminate all mechanical vibrations. Our power supply capacitor are premium Audio Grade Nichicon capacitors which are selected for two reasons audio performance and reliability.
To eliminate the loading effects on preamps and Home Theatre Processors the input stage of the amplifier uses a matched JFET which have very high input impedance.
The signal path is direct coupled meaning there are no capacitors to degrade the sound quality.
The amplifier topology is unique in that the signal amplification is realised in the current domain and this achieves both excellent linearity and has greater immunity to power supply noise (PSSR) resulting in greater musical transparency and excellence in tonality.
The power output transistors are Ring Emitter Transistors (RET) and these devices have a 60Mhz bandwidth and lower distortion and this results excellent sound because they can produce a balanced sound across the audio range with tremendous amounts of power.
Massive 1800 watt power supply insures that each channel receives the appropriate voltage and current at all times, regardless of input signal or speaker load.
Each channel can deliver its rated 200 Watts into 8 ohms and a peak power of 400 watts into 2 ohms to assure tremendous dynamic headroom for life-like soundtracks and special effect passages.
Specifications
Power per Channel (Watts RMS)
8 ohms 200W

Thanks cfrizz, I should have posted the link appreciate it.
Its only just been released but no doubt pics of inside should be available soon.
Waking up seems to be what my Lsi's seem to need and I am really hoping this amp will do it.
