Description :
The Sun Audio SV-2A3 is approached with a very minimalist design, which conforms to the "less-is-better" rule of hi-fi. The chassis is clad in an understated shade of grey, with a gold-hued front panel which houses nothing more than two volume control knobs for left and right channels respectively and a flick on-off power switch. In the middle of the fascia is a plate that proudly bears the make and model of the amplifier. Construction-wise, the amplifier is as solid as a brick, and there is a very reassuring feel to the entire rig. The tube complement is mounted towards the front of the amplifier, comprising two 2A3 tubes as power output tubes, with two 6SN7GTs and one 504G tubes beside them. Sitting directly behind the tubes are four transformers, which is the norm for tube amplifiers. It is a single-ended design, power output is relatively low at 3.5 watts but performs beyond expectations. The Sun Audio SV-2A3 utilizes Tamura transformers are held in very high regard by audiophiles, and are part of some of the best transformers available. The internal layout is carefully designed and exceptionally neat, a real testament to Sun Audio's effort. The power cord input is of the usual IEC variety, which gives some room for experimentation of different cords.

Listening to the Sun Audio SV-2A3 is a very immersive experience that draws the listener to the music. It brings out the richness of the sound really well without signs of any hum or distortion. Individual instruments can be easily discerned in a five-piece ensemble. In classical music, the listener can understand how interactions between instruments weave and interlace around the main melody to create pieces of masterfully designed music. It is the nature of a single-ended amplifier to have very good vocal presentation, and this is no exception. Vocals and choral music have a tangible feel, and the sensation that they are in the same room performing is commendable. On slower pieces, there is an increased intimacy with the vocalist and sounds as if their feelings are pouring out from the music. The Sun Audio SV-2A3 is a superbly musical amplifier that must be listened by those who are considering a top quality unit in their hi-fi sets.
