  1. I think there are some DSD people here, including @kevin gilmore but Andrea Mori just announced his new DSD-only design that accepts external oscillators:

    Only drawback is that you gotta use his FIFO to interface with his products, which adds a pretty hefty chunk to the buy-in.

     

    Not really meant to be a shill post, but I put his AD1862 DAC together and it checked off a lot of boxes for me in terms of flexibility in tweaking both the digital and analog parts. I'm pretty happy with the sound- I was gonna post it earlier but kind of slipped my mind.

  2. Can anyone remind me what the difference between the all-black 007MK2 and the 007A are- build-wise or sonically? I remember reading that some of the parts aren't swappable but I'm not really sure what there could be that would be incompatible. 

    Is there an S/N range that guarantees you're getting a specific revision of the headphones?

  3. I run mine at 20ma/400V and I think it gets a little strident in the highs- more noticeable on the non-007 models.

    Simmconn did some measurements that may or may not back this up:

    Depends on what power supply you're using, iirc 450V required either taller or stacked caps which is why I didn't go that route

    I've been meaning to turn down the output current but I need to root around for the adjustment documentation/tips

  4. I spent a bit of time with the O2mk1 fitted with 009 pads because I read a few posts here and there, seems like it evens out the bass impact a bit (general sense of balance between high/mids/lows) but at the expense of making vocals a little too shouty for my tastes. Essentially you get a bit of the artificial hi-fi flavor, not terrible but it starts to grate if you listen for too long. Eventually ended up switching back. 

    I'm curious about the old brown pads, I've forgotten how they sound...

  5. I guess dCS decided that headphone-based systems are now worthy of their time: https://shop.dcsaudio.com/products/lina-system

    Figured most people would be interested in the amplifier so I put it in this section:

    DAC includes crossfeed EQ (didn't look into whether it was software/hardware), compute module on the side for either Roon or whatever dCS decides to do in-house. Looks like a scaled down version of their ubiquitous Ring DAC

    External clock lets you use the DAC with OCXO's instead:

    Full system cost seems to total 29,150 USD. Price aside I think the casework is pretty cool, I saw esoteric do similar things with some of their new offerings.

    At this price point though I feel like it'd be more cost-effective just to pick up one of their older offerings (like the Debussy) and hook up a Roon endpoint to that...

  6. Just as a sanity check, with the GU50 substitution you don't really need offboard heatsinks anymore right? the KGST only needed those PCB mounted ones. 

    My idea was just to fix the 10m90s devices to the sides of those hifi2000 cases with the quasi heatsinks, seems like a nice little project to use some of the older boards I have lying around. 

  7. I think a lot of people are convinced that the obscure stuff they stumble upon in audio is new/bleeding edge/disruptive, moreso when these designs aren't out in the open. That new car smell makes people defensive when technical stuff gets thrown around.
