I am the happy owner of a set of Beyerdynamic DT770 Pro's. (80Ohm version, in retrospect the 250Ohm probably would have been better, but you learn with time) I think they sound great, but lately I have had a little problem that bugs me.
I have been driving these out of the back of my computer, using the 300ohm max headphone output on my Creative Sound Blaster Titanium HD. I am liking the sound quality. It's better than anything else I have ever heard, but I don't know how the DAC and amp in it compare to what you guys on here use (probably not favorably). (In a separate topic, maybe I should replace the op-amps in it for better sound quality? This I know nothing about, just that they are replaceable.)
The biggest problem - IMHO - with this sound card is that it has a mechanical switch in the headphone out jack that automatically disables all other sound output, so if I want to use my stereo amplifier, I have to bend down under my desk, find and unplug the headphones from the back of the computer. Then when I want to listen through the headphones again I have to go through the same thing in reverse. It is very very very very annoying!
I was thinking maybe there is a headphone amp out there that can help me solve these problems, and get me some better sound out of my headphones at the same time. Since I already have an OK DAC in the sound card
What I would be looking for is something like this:
1.) Line Level Analog RCA out on back of sound card -> Headphone amp
2.) 1/4" or 1/8" jack on headphone amp to power headphones (capable of supporting up to 300Ohm if I ever decide to upgrade cans)
3.) Line Level Analog RCA output from headphone amp to my stereo amp so don't have to keep reconnecting things.
Can you guys recommend something like this, or maybe another solution I can use?
I'm looking to spend no more than ~$250 or so.
I appreciate any suggestions.
