Preamp w/ Phono and Headphone

Most preamps with headphone outs, use cheap op amps, Because you have the excellent 650's I highly recommend you get a headphone specific amp. Look at Headphone.com.

Agree to the most preamps having cheap opamps to drive headphones, but my CD-player/recorder/DAC/ADC has an excellent headphone jack that would drive senns in the very competitive level of listening.

Thanks for all the good feedback. As for price range, it's variable - my biggest concern right now is that I am now living right on the ocean, and everybody here tells me that everything rusts. I had a nice Ayre K-1x preamp with phono, but didn't want to risk bringing it here and having it damaged by the salty, moist sea air. So, for now, I'll probably keep it modest, but I appreciate the high-end suggestions as well, as I may decide that will work.

I had wondered about the quality of a headphone jack in a preamp. For flexibility, something that will take a digital input and be small enough to transport likely makes the most sense, since I would be able to travel with it if desired. On the flip side, every box you can eliminate helps in a small space.

Consider the Marantz SC11s2. Has both and they're both good.
