This is my first-ever post on the Harbeth User Group, though I have been reading for quite a while with great interest, let‘s say almost for two years. It is a truly great forum. As I am not a native speaker I can only apologize for my mistakes.
I have purchased a pair of C7ES3 one and a half years ago and am very happy with sound quality and sound stage. Nothing to moan about (except for a lack of listening time) and not much need/aim to change anything. I did a lot of comparison with different amps and speakers beforehand with dealers and finally ended up with a Naim Supernait, a Naim CD5XS with a Powerline cable (which was a giveaway with the Supernait) and the C7ES3. A Macbook Pro is included in the setting if needed via Coaxial Digital and the M2Tech HiFace Converter. So far so good.
Unfortunately the first thing I feel I have to write about is an issue concerning the aging/development of the veneer and its (possible) consequences. The units are driven in a normal Mid-European living room, with constant temperature between approx. 18-27 degrees Celsius and a humidity between 45 and 55% depending on winter/summer. The cabinets are not exposed to direct sunlight though one is closer to a north side window (no sun from the north in Germany) and still I interchange speakers every half a year or so for brightness issues. Colouration is fine though.
Nonetheless the veneer on one of the cabinets shows signs of drying with multiple hairline cracks (only) on the back panel. This affects almost the entire back of one speaker cabinet, while the other one is hardly affected. It is clearly visible and you can feel the uneven surface when touching the back of the speaker while cleaning it (in fact this is the way I first noticed). I never used any wax or powder or whatsoever but a dry cloth-like thing (these so called „Swiffer“ things, if you have them in the UK) and never applied any liquids to it (how could I?).
Although the issue is difficult to capture in pictures I would like you to have a glance at the attached image (which shows only a detail).
Now my questions are:
- are these normal aging effects after one and a half years?
- will it anyhow affect functionality or sound quality? This question before the background that I read somewhere on the HUG that the cabinets are also veneered on the inside for sound quality issues, right?
Well now, I am looking forward to your replies and helpful hints.
