I auditioned the ASR Emitter I at the local HiFi dealer a couple of hours.

It is in actuality a Hi End, high-gain integrated amplifier that makes the use of preamplifiers unecessary, but if you use several sources, this means running multiple interconnect-cable-pairs from the sources to the ASR Emitter.
Alternatively, if you place the ASR Emitter close to the sources, you need to run a pair of long speaker cables to the speakers.

At the Hi End of the spectrum, manufacturers almost exclusively use discretely designed amps using transistors. It gives the designers the complete freedom to tailor the sound of their design.

However, at the low end of the catagory, manufacturers tend to use Integrated Circuits since they are cheap, very easy to implement as amplifiers, and have guaranteed performance data from the semiconductor manufacturer (distortion, bandwidth, noise etc).

For that reason, I was puzzled by the fact that ASR Emitter's gain stage is entirely IC based! Specially considering the overall cost of this amp!

We tried all different types of recordings (acoustics, live concerts, studio production jazz, classics, etc) with many different speakers, both large 4-way speakers and small monitors, LPs and CDs and SACDs and so on.

To be honest I don't get what all the fuzz is about. It sounded very ordinary and "plain".

There was a general dark signature to the reproduced sound that tended to neutralize the defintion and resolution of the upper harmonics
Midrange was again ordinary and dark with a percieved lack of inner detail.

Bass was deep and powerful, probably the ASR Emitter's winning virtue.

Another positive characteristics was the lack of percieved grain, etch or over-emphesized mids or highs.

I asked an audiophile friend to audition the setup and inform me about his take on the ASR Emitter:
Unfortunately he confirmed my observations, and expressed his similar findings as a general dark sound field with a lack of detail compared to other Hi End systems in the shop.

I even asked the Hi Fi shop owner and he told me that he found the ASR Emitter a good but slightly dark amplifier, and expressed that it would be a good mate in bright and analytic systems.

As wonderful as the ICs measure, I am yet to hear an Integrated Circuit that can match the sonic presentation of the best discrete designs.

For more info on why discrete designs are better, read

It is a bulky design with several seperate power units and tethered power cables, that I found very unusual but cool. However, I dont feel that it delivers the sonics. The competition is TOUGH at this price, so do search the market before a purchase.

Good luck!
