    Looking forward to your impressions. When I fitted the Burson V5's to my Eastern Electric Minimax dac there was an immediate and obvious improvement.

    Well, I lied.
    I found a spare 15 minutes, whipped the sound card out and installed the Burson Audio V6 Vivid dual op amps.
    I fired up the PC, and initial impressions are promising. The audio is better defined, sounding immediately cleaner.
    I will get some hours on these, and post my thoughts up, quite possibly in a different thread, as this has now gone way beyond USB.

    These Vivids make me wonder how the classic sound.
    I am very happy with the immediate improvement, and will now have to repeat the sound card / DAC comparison as the results could be very different now.

    Can you put the Bursons in the DAC to make it a fair comparison?

    I am not sure I can, but I was going to use the optical and coaxial out of the sound card to feed the DAC.
    If this sounds better, then I will be an even happier man.

    The op amps are superb.
    I am seriously thinking about replacing the op amp in my PD-S703 with a V6 vivid.

    I had a couple of V5 Opamps for a while and they were excellent. Charles does some good stuff.

    Phase 2 will begin soon.
    I will be removing the “all in one” liquid cooling system, and will fit a passive CPU cooler.
    I have also finally ordered my new PSU. This will work in hybrid mode, so the fan will only kick in when it gets a bit warm.
    I will also be ordering a passively cooled graphics card, when I make my mind up about which one I want.

    The system will be transferred to a better case - a Fractal Design Define R5 and case cooling fans will be minimised to reduce noise levels, both ambient and electrically.

    Then it will be time to see if this makes any difference.....

    I found that moving to a PC without any moving parts, only passive cooling, going headless, no graphic card, stopping all unnecessary services and only using the PC for audio rendering made a massive difference in audio quality. Well worth the effort. I hope you also find the same in your experiments.

    So the PC has been transferred into it's new home. A passively cooled graphics card has been fitted.

    I am thinking that I still need to keep some airflow going through the case, so I will fit 2 quiet case fans (Nanoxia 140mm Deep Silence 1100 rpm) as intake, and one for the exhaust.
    I will connect these to the motherboard using a Phanteks fan hub, as I don't want PWM fans adding the 25kHz noise to the PC.

    To also help, I am thinking of fitting an Elfidelity Fan Noise filter between the hib and the motherboard.
    Do these things work?
