…One of the real strengths of this amp is the quality of the midrange. I haven’t owned a lot of tube equipment, but there is a definite organic quality to the mids through the Jungson. This is where many of the key parts of the music reside: vocals, strings, etc., and these are imbued with a realism and naturalness in their sound. I did most of the listening through single ended RCA inputs.

Although the bass goes deeper than the previous amp, it seems the last few lowest frequencies don’t have as much of an impact as they should, but this may be partly due to the demanding impedance curve of my speakers (which drop below 4 ohms).

Well after the break-in period (50 hrs?), the front to back soundstage has become quite deep, and I’m often surprised at how some recordings allow you to pinpoint the position or layout of the orchestra. You can set back and not have to strain or concentrate in order to locate the french horns, timpani, flutes, and so on. With other amps I was fooling myself trying to imaging they were one place or another, but the Jungson makes it clear and obvious given a good recording.

The high frequencies are very well extended and exceptionally clearer or smoother than other amps I have owned, quite free of grain or hash that was so apparent when I went back to a Yamaha receiver temporarily for comparison.

The sound tended towards lean, but never really became dry sounding. I think it is more of a neutrality thing, because I was used to the warmth that the Audio Refinement added to the mix. The Jungson is much more neutral, so don’t expect it to add romance to recordings that don’t have it!
