The rear is protected by three massive "hoppers", which are transformers with cast frames. The front panel of the thick plate blackened aluminum succinctly decorated with three light handles (input selector, volume control, power switch), which will have to be manipulated by hand - the remote control is missing here. Similarly asceticism is different and the rear wall of the chassis: not counting the mains socket, there are three input stereo pair on RCA connectors and three acoustic terminal on each channel for acoustics with different resistance. In the final stages of working four domestic ray pentode 6550. Two 5Z4P, two 6N8P and two 6N9P, but made in China - it's transistors, rectifiers, drivers, and the input of the lamp.

As always, this unit needs a thorough warm-up before the first use and a little before each next audition. Speaker cables need to be connected carefully, choosing the dates of two screw terminals of the three proposed for each channel. In the transition from the regime in ultralinear triode suggested output volume to zero. And another tip: buy a Pure Sound A30 tube phono stage, especially if you prefer classic styles, academic and chamber music - he significantly adds sound of air purity and naturalness, and for pop and rock music is fine something decent but on the "stones".

Now, as promised, the difference in the sound. In fact, the global differences from the younger model we have not heard, but triode mode gave more liberated, beautiful sound with minimal distortion, but not too well-controlled bass and ultralinear provide enhanced dynamics, the sound was collected and clearer, but some kind of pale. These properties of just and can be used in the amplification of music of different genres of music.
