The sweetness of the treble is perhaps the best I have ever heard. It also majors on timbre, tonal colour, which is important to me and its resolution of low level detail is outstanding. Pretty much ticks all the boxes in what I look for in an audiophile component in fact. The last time I saw one of these is when they made them. So beacuse people don't know how good it is I made a video clip to try to demonstrate the excellent sound of the amp; with the caveat that they were recorded with a hot shoe mic, so the camera pre-amp is involved and, well, YouTube, but I think the clips give an idea of the quality.I must say this amp is particularly strong on the resolution of low level ambient detail, which can make listening to well recorded material so involving - string overtones, musicians moving about, flautists' breath, finger plucks and guitar string squeaks. All those kinds of quiet spatial cues which deliver that sense of'being there' or of peering into the moment in which the performance happened. Indeed you are welcome to come around and have a listen to it if you are able to. You have fourteen days to try it out in your own system. The amplifier is in superb condition as you can see.
