What cause tweeters hiss ?
@westcoastaudiophile have you tried another DAC? I don’t have extra DAC, only D90 and Ares II. @gs5556 Does the Sony CD player have a two prong plug or three? Two prong without ground. The problem could be in the XLR connections of th...

@lonemountain  Hi Brad. Thanks for your clarification on ATC speaker break in. On similar woofer glue you mentioned. I have had made a mistake using dry microfiber to remove dirt on woofer.  Alas, few fabric sticked to woofer and glue, I didn't ...

I was told by few friends that ATC speakers have been tested with wide range frequencies during QA/QC test, is that consider break in ?   
Recommendation all-rounded speaker (small room)

Recommendation all-rounded speaker (small room)
@ghdprentice @digsmithd Thanks guys. Finally I got SCM11 setup and listened over the weekend. Initial impression , it delivers a wider sound stage than my previous Sonus Faber.  Deeper bass and sweet mid range (vocal) and much detail on higher mi...
