Headphones-How to Connect?

Sennheiser are high impedance ear-phones that might not be handled with CD-player or even preamp headphone jack.
In most cases head-phone amplifier is recommended for more pleasure to your ears.
Try to get Earmax or visit www.headphone.com to select an appropriate amp for yourself.
Please note that the amp has to handle 600Ohms load.

Mendota 98: I have the Sennheiser 600's with the upgraded Cardas 10 Ft. cable. I've owned the following headphone amps: Musical Fidelity X-CansV2; Creek OBH-11 AND OBH-11SE, Grado RA-1, Earmax, and Sugden Headmaster. The one I have kept is the Sugden Headmaster, connected to my preamp with Cardas Neutral Reference interconnects. We all have our preferences of course, but I found the Sugden to outperform the others by a fairly wide margin. The Earmax basic version, in my opinion, does a fairly poor job of driving the 600's. If you decide to go Earmax, I'd purchase the Earmax Pro. Good Luck.

I use a pair of Sennheiser 600's with an Antique Sound Labs MG Head OTL amp. The amp really isn't too expensive and they sound surprising good together. Try visiting www.head-fi.org , pretty good site to help you figure out what you may want.
