XLR interconnects

No, XLR cables may be able to benefit SQ somewhat even if all components are not fully balanced, differential, mirrored, etc.

Whether it will truly make a difference in sound is something you'd have to test.

Hi randy-11

Yes in the end I would have to have an audition at my local dealers to see if I can hear a difference for sure. Thanks for your information.

i noticed a difference in XLR's ...  lowered the noise floor, quieter background noise....  can't hear a thing in my system... my components are balanced as well though... even if your components isn't balanced, XLR still helps...  not all XLR interconnects are true balance design... if it doesn't say they are in the description then you better ask the manufacturer .... 

on another point.....I noticed that the sound of dif. bal. interconnections have far less sound differences in the many brands that are offered...

Agree stringreen. XLR's can sound good on a reasonable budget, whereas you have to up the budget substantially more to get to a similiar performance from RCA's.
