  1. Btw, what's the general consensus on Glycine? I've seen it pop up on Massdrop and some designs are interesting, but border on tad too garish for me. This seems like the right kind of black.
  2. I'm pretty sure you'd use analog in this case only to connect a phono preamp. Otherwise it's a DAC/AMP unit. As for DSP, I'm probably biased, but I've never encountered any headphone which lost more than it gained by properly applying measurement based tonal correction. With stuff like this available I see no point in using regular USB->I2S converters. Bake in a profile for headphones and a different one for your speakers/room. Switch with remote.
  3. It's another format cashgrab. The only reason it's known is due to some highly connected ex-Dolby peeps behind it. Streamers are desperate for a differentiation factor, so they grab every straw they get. Credit: I work for a company which might be able to deliver the superweapon the streamers need. And it doesn't involve selling all your gear/music. Thus we're sort of competing with MQA, even though our methods can be compatible.
  4. Hot damn! Must be the best finish I've seen on a PCB for long time! The precision reg isn't hard to solder per se. You just need paste and a hot air station for the power pad.
  5. For 95% of the folks the answer is - hand it over to someone with an oven. It's doable by hand, especially with a hot air station for the power pad and then dragging along the side pins. Most likely I'll be buying a pair of AMB regs.
  6. A small thanks for @sbelyo and the rest of the gang. A Mouser project for available parts -http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=497a265867 It includes the smt regulators, you might want to use AMB labs modules, so revise accordingly.

  8. You can try this - http://www.diyaudio.com/forums/swap-meet/299822-fs-soekris-dam1021-rev1-0-02-bc550-mod.html These are the earlier boards, but seem properly modded. As for the input board - I might actually be able to sell you one together with an Amanero USB->I2S converter. It will have on board connection for volume, input switching and input indication. Ideally you'd want an extra 12V DC power supply because that supposedly improves the noise floor/sound. For a leaner build I could also ship you a proper 7VA transformer to use with the DAC. Here's one of the last images of my DAC still in operation. You can see the input/control board.
  9. If anyone wants to get rid of one Dynalo mini PCB, give me a shout. It'd be superb if you'd also be willing to send one Alpha quad pot my way. For a fair compensation, of course.
  10. Anyhow - if someone wants to get a good taste of that multibit goodness, get the soekris board. Some come up cheap 2nd hand, just make sure that you out-ninja other folks who might also get their multibit sweetooth on. I got mine right after they became available. At first it sucked ass and was borderline a disaster. The guy who designed them is pretty experienced in digital electronics, but not so much in analog, so there were fuckups. And by fuckups I mean a few guys got their stuff blown up because of asymmetrical PSU loading which spat out an uber nasty DC transient on powerdown. Also initially digital filters sucked, so they had to be swapped out. Same for Vref capacitance, which used to be lacking. Supposedly that's been sorted for rev4, so if you're up for it, get a half decent +/-12V DC PSU and try to find a good input board from my compatriot Normunds at DIYA. Some folks say that, if done right the DAM can trade punches with Yggy and come out on top. In the leaner implementations it's still one of the best diy DAC options out there. However, if you hate hassle/adventure, just get the Modi Multibit. I think that it's a much better option than half of the old multibit big iron DACs out there. P.S. Should any of you need info about working with Soekris boards, drop me a pm. I've gone through DIYA threads, so you don't have to. P.P.S. I killed my board by lifting one of the Vref cap pads.
  11. There's a Soekris module inside there, so it might sound good. If they have bothered to change the digital filters and modded the PSU loading so it doesn't kill your downstream stuff on powerdown... *shakes fist at Birgir for ninja-ing those two boards*
  12. Has anyone actually built the CFA3? On one hand, there are plenty of decent smart choices for driving headphones nowadays (maybe it's different for stats), but on the other - I'd love to build something insane for a change. So, I was thinking - 2xGR PSU's powering a pair of CFA3 boards in a 2U 400mm Modushop case. Double Joshua tree attenuators for volume control. Or should I just stick to ebay Dynahi kits and sit my ass down?
  13. LS50ies are a safe bet, if you need bookshelves. The ELAC coax bookshelves look nice, but i can't understand the advantage of using a 3-way arrangement if you have 5-6" woofers. And yeah, get a sub if you can.
  14. Bah, just use a DAC which has a memory buffer and galvanic isolation. It will sound the same with any input, because jitter will be dictated by the on-board master clock and galvanic isolation will take care of most of the ground/line crud. The only price to pay for this would be latency induced by buffer size. Mine adds 0.5ms. You can't just go spewing out stuff like "USB is dead, because my AOIP gear makes me feel better/different". P.S. Just keep in mind guys, that USB audio can't really be compared to other data transfer protocols which have error correction. USB audio can't do checksums and repeat sends, it'll just cut out, if the stream gets interrupted. In theory you could make an audio transfer protocol which would have a buffer and then attempt resends for bad packages until the buffer runs out. Think - anti-vibration systems on those portable CDPS your cool friends had.
