252 harshness and burn-in
Posted by: eagle3333 on 18 April 2016
I've now spent about 50hrs listening to my 252 - which had about 20hrs on it previously as ex demo'. It's been hard, 'digital' with brash, sometimes painfully shrill leading edges all this time until Saturday night. Fed up, I disconnected the burndy and re-connected. Epiphany moment. Harshness completely gone; smoothness, warmth, delicate articulation instead of brashness and a filled-out middle making for a huge stage. I laughed out loud with relief and played through the audition tracks I've heard so many times that I can properly tell a difference in SQ. Same story, so not my imagination. Then, 25 minutes later, it all went horribly wrong and I'm back to that horrible hard edged sound without warmth, syrupy smoothness replaced by brash transitions and reduced stage. I've raised this before, but re-raise it because it came so right and I thought I'd probably found the cause as being an incorrectly fitted burndy. Apparently not.
Digi out on NDS is disabled; I've muted tuner record on 252; brains and brawn cables are all separated. Owing to my platform I can't keep the middle 12" of burndy/snaic (which run a half inch from each other) off the wooden floor; but when I moved the 252 higher to achieve this it didn't make an audible difference, anyway.
Can anyone comment? Is there a problem or is this still symptomatic of the vaguaries of burn in? I compared my 282 with 252 and found the only real difference to be 282's wafty, vague base - compared to 252's tighter bass. But, if the 252 was still sounding like it did for those 25 minutes, the differences would be far wider and greater. 252 is still on review but I can't sit on it any longer without making a decision. If it's eventually going to sound like it did for that moment then I have no doubts at all about buying. If it isn't, I think otherwise. (The Hugo is off the system pending sorting this out. Thus far it's just exacerbated the too-harsh leading edge issue..)
