  1. USB Type-C DACs?

    The thing is that most stereo DACs are good bandwidth wise with USB 2.0, so I wouldn't expect much in terms of adopting new standards on the DAC side. Just get the right cable and you should be good.
  2. Phenomenon Libratum

    It should be trivial to measure the acoustic impact of an obstructive material. Your dust cover should be invisible acoustically, from what I can see. The worst it can do would be rattling, which is trivial to detect and rectify.
  3. Phenomenon Libratum

    HD800 is anything but flat sounding. That treble is outpeaked only by Beyer T1.
  4. What Are You Building Today

    Four of these - http://www.sbacoustics.com/index.php/products/subwoofers/12-sb34swnrx-s75-6/ I did plenty of research and my main goal was to find a light subwoofer driver which can do twenty. Initially I was looking at Dayton, but they're poorly represented in EU and they're anything but light. A high Mms/Bl factor was a must. Scanspeak had a 13" which was twice as expensive. Other than that I had to look for exotics like Audio-Technology and Accuton which are even more expensive but TS specs aren't any much better. SB Acoustics is actually a very decent manufacturer, but I'll mention that one of them came with a minor defect that's audible on higher excursion. Let's see how they'll handle it.
  5. What Are You Building Today

    My new monitor stands. 114dB free field at 22Hz with only 500W. And there will obviously be two of them.
  6. The Headcase Stax thread

    Here's how the Staxen I had measured. Lambda Pro Lambda Nova Classic For reference - HD800 Overall the Pro sounded more anemic and I preferred the LNC. The earlier roll-off is clearly audible.
  7. The Headcase Stax thread

    Ain't mine! One of the luxuries of my work is that I get to try out many headphones that pass through us (no, I don't work at the post!). The amp has been modified, judging by the fact that RCA's are not stock and there's only one pair of them. Maybe even one of yours, eh? Luckily I'm knee deep in another audio project, so there are no free funds. Otherwise I'd be looking for a PCB set and maybe a pair electrostats.
  8. The Headcase Stax thread

    Finally got my stat cherry properly popped. Previously listened to a SR-202 from that small Stax amp and it didn't do much for me. Lambda Nova from SRM-1/MK2 sounds really good and bass is actually there.
  9. Okay, there is something to those electrostats. Didn't get it with the SR-202's, but Novas from SRM-1/2 float my boat. u9T841e.jpg

  10. RME ADI-2 Pro, swiss army DAC

    OPA1688, OPA1612 and OPA1622 if I'm not mistaken. I think it's the first commercial device to use the OPA1688. Usually one uses opamp and a high current buffer to isolate the opamp from the load and get it to dominate small signal performance. The usual suspects back in the day were OPA134+BUF634 sharing the same feedback loop. In this case RME opted for three OPA1688 per channel to distribute the load, or six for balanced. I personally don't subscribe to the Burson-esque notion that all IC's are bad. In my experience opamps excel in small signal environments with fixed or at least predictable operating conditions. Here RME proved me wrong with their headamp. Interestingly enough the headphone output shares the same distortion characteristics as the line outputs and can be used as such in a pinch (if one needs 4 analog channel output).
  11. RME ADI-2 Pro, swiss army DAC

    Our head of RnD uses a Fireface UC and we've relied on a Babyface to not leave us with our pants down when we tour high profile LA studios. Rock solid drivers and well thought out controls. Sadly. they'll never outsell stuff like Behringer or Focusrite because it's hard to sell reliability to people who have never been burnt. Sure is. But it's hard for me to just call it a DAC. The thing comes with a 80 page manual to cover all of the features and functions. You have ADC with actual 124dbA SNR, you can use it just as an analog input, but it wouldn't be out of place in a world class mastering studio. It has two headamps which can be configured to play different tracks, if your playback software allows it. Or you can just tell the unit to take each of the DAC outputs and utilize each headamp for differential drive. Oh, and it'll detect automatically if you're using SE or BAL...
  12. The State of DACSES

    Output spectrum is actually something I would expect to see from such ladders. With that said - most of the harmonics are -100dB below the signal, so it's okay in my book. I mean - I've heard better measuring DACs which have sounded far worse. Stock Buffalo 3 for example. Btw, this might interest the mafia members in possession of DIY Soekris modules.
  13. The State of DACSES

    Looks like it's the age of no-chip. I was very impressed by the sound of first edition Soekris boards. It took two extra revisions of the board and around a year of firmware updates to get there, but now it's pretty stellar. I'd love to hear what DAC1541 has to offer. I'd also say that some of the higher end implementations of Asahi Kasei chips sound really nice. I went from DAM1021 to RME ADI-2 Pro and don't feel like I'm missing anything sound wise.
  14. Picked one up mostly due to an interesting feature set. I've had good experience with RME gear being technically impeccable, but falling a bit short in listening tests. The ADI-2 Pro was intended to be an office rig, but I lug it to and fro work, it's that good. Ended up buying one of the limited Anniversary Editions, cuz it's black and has moar pretty. It runs my HD800 balanced with 6x OPA1688 chips pre channel. Sounds as good or better as I've heard any HD800 perform. It also does 5 band PEQ which makes HD800's actually listenable. For my Equator Q12 I use the back XLR's and intend to hook up a MiniDSP via optical to integrate two custom 15" subs. Anyho - check this thing out, if you're looking for an interesting source unit. Cheerio. P.S. Nudie (almost Gilmore sized)
