headphone amp


Looking for suggestions for a headphone amp that will drive either grado or sennheiser phones (low to high z). Something that retails for under a 1 k $. Have considered the Creek amps and the Grado amp - any experience with these (and what phones wre used with the amps), or other recomendations for amps in the 1 k $ retail and below would be appreciated?

There is no real need to spend that much on a headphone amp to get good sound. I own both Grado RS-1 and Sennhiezer 650HD.

If you need just an amp (no remote) the Gilmore Lite from headamp.com will do the trick for $400. They also sell "better" amps too. If you want a tube amp the brand Single Power is worth checking out.

Also benchmark's DAC1 has a good headphone amp too. It could also upgrade your system's DAC depending in what you own and start at $1000.
"If you want a tube amp the brand Single Power is worth checking out."

NO do not even think of Singlepower! Please read all the threads on head-fi.org about Mikhail's dangerous shoddy engineering and fraudulent business practices. He has disappeared, leaving many customers out $$$ and equipment. While his amps once commanded a stellar reputation, he has been exposed as a fraud and crook.
Don't buy any used Singlepower amps either unless you are an engineer and can redo the wiring.
Do not buy Singlepower! He ripped me off for $6K on the last amp i got from him. they are also hit & miss on the used market. (mostly miss) The remarks "fraud and crook" are being to nice IMO. Stick with offerings from Headroom or Headamp, or Woo Audio.
Lots of info on www.head-fi.org or www.head-case.org
