Ypsilon Electronics Aelius Monoblocks

Just taken in on trade is this terrific sounding Ypsilon Aelius Monoblocks.  
They are in excellent condition and sound amazing!
The amps come in their original wooden crates and the preamp comes in its flight case.

Aelius is a push-pull hybrid monoblock power amplifier using two gain stages with no overall feedback.

The first gain stage uses a tube in single-ended class A operation, transformer coupled to the output stage. It is unusual practice to implement an inter-stage transformer in a solid state or even hybrid amplifier. With the transformer two tasks are achieved. Perfect phase splitting and low impedance drive. Thus no need to use an additional intermediate amplifying stage, so transparency and purity of the signal is preserved.
