I have a fire phoenix Dac-05 powering beyer dt 880 600 ohm headphones. I'm thinking about buying a tube amp.
Is it possible to make a line out from this unit?
Yes there is a RCA output.
my ad797br came in yesterday, and i listened to dsnuts advice and decided to let the ad797br get used to the circuitry around it by playing music nonstop over the weekend. if i hear any kind of oscillation in the next week, this thread will be the first place i post.
i did find a VERY useful thread on ad797 but it is at least 3 years old, and i'm not sure if it's still relevant to the AD797s made today.
How goes the AD797 burn-in and are they running hot? I'm still waiting for my AD797 to arrive.
im still burning them in. better than when i first listened to them but not quite there yet. i already talked to dsnuts about the harshness i'm hearing when it comes to violin frequencies. it might be my imagination but they sound a tad sharp. he said for better or worse to let them burn in a little bit more. the ad797 gets warm but not hot like a gtx480.
well i put away the ad797. i didn't like it afterall. some frequencies were harsh and not smooth as i'd like it to be. LT1028 I ordered last week came in today and so far... i like! i can see why dsnuts was mighty impressed with them stuck in the FP-02. and the bass came back! i was using the stock op amp and missed the feeling of the bass a bit.. now i don't. again this was using the AD900X. i'm pretty much done on my journey for now unless there is another dac/amp that has great synergy with the AD900X at a good price point.
only concern now is the FP-02 makes a slight buzzing noise whenever i turn it on. i have to give it at least 2 minutes and it goes away. i'm not sure what it could be. i hope it doesn't become of a much bigger problem in the future. i already checked the power cable and USB cable. those aren't the problem.
I got it in November and only used it on weekends so maybe 100 hours tops, it sits on top of my $128 Tianyun Zero 24/96 which has worked flawlessly since mid 2010, which is probably tempting fate now...
This is the 3rd cheapy I have bought from eBay that has failed or not worked from scratch, other casualties include
SD-1955 - DIR9001 AD1955 DAC Optical Coaxial Decoder & Power Adapter - the coax did not work at all (got a partial refund)
USB DAC (PCM2707+DIR9001+PCM1793) + Headphone Amplifier - worked badly with enormous hum on power supply for a week then failed - this was from MUSE Audio
Happy to report that both of my DAC-02 are working perfectly again. I uninstalled my sound device and reinstalled it and now all inputs on both are working fine - bizarre but true. That this also re-enabled the USB input is the most strange as they are independent on the PC and the Zero was working on USB fine all the time.
Before uninstalling/reinstalling the sound device( IDT codec) the optical output was also definitely working and connecting with my Zero perfectly well just not with the DAC-02.
This falls into the category of strange but repeatable such as if I want to view Netflix streaming I often have to turn the wireless printer or Ipod wireless on 1st
