Does an integrated DAC/Headphone amp exist?


Im looking for a cost effective way of having decent sound and work. Loudspeakers are out of the question so headphones are the ticket. I was wondering if such a device exists as to not take up too much space on my desk as well as limit the cost of cabling. I would like to keep the cost under $1000 for the headphones, cabling, DAC and amp. I want somthing that is musical and easy to listen to for 8-9 hours a day and I prefer over the ear style 'phones and open air designs as to still be able to communicate with coworkers without removing the headphones each time to talk. I would be using my PC as the source. Can anyone recommend a good starting point for each peice of this puzzle? Thanks

JLind325is,

Aside from those mentioned, two that I have should do the trick -

Meier Audio Corda Opera - Headphone Amp, DAC, and Preamp @ USD 1,000: and,

PS Audio GCHA Headphone Amp & DAC @ USD 995.

Sorry . . . just saw that you wanted to keep the cost USD 1K including headphones. That said, just saw a GCHA go here on the 'Gon for about USD 700. If you could find a similar catch, you'll be in business. If you can't and are willing to stretch, either of these would likely serve you well for a long long time.

PS - Just curious, does the 325is in your moniker refer to your ride??
Another vote for the Benchmark Dac 1. You can buy the Sennheiser HD580s for $129 on close out shipped from Amazon and you will have a very nice sound.
Thanks guys for all the suggestions. I havent looked into DACs previous to this, i didnt know so many can double as headphone amps. I think I opened up a can of worms for myself though. I have been thinking about modding my Denon 2900 or buying a new player. Would the Denon be a decent transport if i decided to get a DAC-1 or another DAC? Or would it be more cost effective to mod my player or try somthing new? Any input on this would be appreciated.

You must be a fellow Bimmer owner. My Bimmer is a 1988 325is, mostly stock but with a few suspension mods. I've always loved the e30 body style, mine has the "ugly" bumpers which is kind of a bummer. But on the other hand it drives great from the inside. :) Shes got 223,000 on the odometer, second motor but still has the original limited slip diff. and transmission. Do you own one?
