CD Player Headphone Jack

I use the 650s and the 702s on marantz sa8001 and cd5004. I have no complaints.

Thanks Rok2id, Any preference between the two Marantz models?

I give the nod to the SA8001 because it plays SACD and I think the build quality is better. But I suspect the headphone amps are very similar if not identical. I just don't think the design teams are given a blank sheet of paper for every model and price point. Most likely their business model dictates that a lot of the electronics and mechanicals are identical. Especially the ones that may not show up on the spec sheets.

Nah, get a headphone amp. Check headfi for something decent.

For those Sennheiser HD 650 headphones I say pair them up with a Grant Fidelity DAC-09 or DAC-11 with a NOS Western Electric tube in place of the stock one. I know it isn't a CDP with a headphone jack but I did find a pair of Sennheiser HD-600 headphones along with a GF DAC-09 a very enjoyable combination. The footprint of the DAC-09 or DAC-11 isn't big at all and there is a lot of flexibility with it.
