Hi, Im currently using a cheap rm1++ dac ,i usually tune 75% of max volume for my hd668B, but for my xp3, the max volume still small , isit due to 98db low sensitivity? This issue even worst when put on Hippo foam which has longer "foam canal"...But hippo biscuit can give me sufficient volume when plug in xp3.

anybody can help solve this issue?..im newbie..thx

Added on October 30, 2012, 9:54 pm1)Im notice the sound is better when in low volume in Hippo biscuit compare to high volume. is this due to xp3 or biscuit factor?

2) for burn in, must use good dac? can use handphone? small kbps song can do?(no time download higher definition in short term)

hopefully audiophiles here can teach me...thx alot
