Hmm I finally pulled the trigger and got a pair of immaculate 1.2 TL's.... am soooo happy :D

I'm looking at hooking these up with a Hafler DH500 amp, am just wondering if I should be concerned with the possibility of the non-common ground issues and interconnect cable with this amp?? I have no manual for it and cant find any reference material anywhere on the web in regards to this....

Also I didnt get any manuals/paperwork with the speakers, if anyone has anything in electronic format that they could send on id be really grateful.

Cant wait to listen to em when they are setup in the next cpl days :cool:

    Measure ohms across the negative outputs on the amp, zero means common ground. For an owners manual, contact Polk and they will mail one to you. If you don't know what you're doing, wait until you get the manual before hooking them up.

    From Page 6 of the Hafler manual....... The black terminals can be connected together for headphones or accessories that require a common ground.

    Cheers for the info... hmm the interconnect cable that I got has a blade and pin type connection... Im guessing that with the hafler amp I would have to have the black terminals connected for use with the interconnect...

    Thanks for the information so far though its been useful... already printed the hafler manual :)
