I bought a new seperates system about a month ago. I undertook extensive demo-ing and was really happy with my purchase: NAD 316 amp, NAD 515 CD player, KEF Q300 speakers. I set the system up at home and even though the interim speaker positioning I had rigged up was far from satisfactory I was really happy with the overall sound.
Gradually over the past month, however, there has been a really noticeable levelling off of the top-end frequencies. Without really noticing it, I have abandoned the 'tone defeat' setting and started to edge the treble higher and higher to get the top end that I want. By yesterday, this had become so noticeable that I re-played one of the tracks that I had originally used to demo the system in the shop and when I subsequently set it up at home, 'Long distance runaraound' by Yes. On this direct comparison, the top end now sounds noticeably flatter and more muted. Bruford's hi-hat work in the verse, which had sounded so crisp and prominent when the system was new sounded far duller. The song in general just didn't shine like it had a month ago even with the treble control nearly on full.
- Any ideas whether this is more likely to be 'running in' issues with the amp or the speakers?
- I bought the system from Superfi. They were really helpful throughout the demo process, but what are my options now, given that there is no actual fault with any of the units?
What has gone wrong here? What would you do in these circumstances? Any advice would be really appreciated.
