  1. Also, Toslink has a transmitter/receiver which introduces noise/jitter as well, so an additional conversion from electrical spdif to optical and back Good coax implementations should use a good pulse transformer (Newava?) and be terminated correctly. Many (most?) aren't. Many pulse transformers in existing equipment may be there more to pass FCC Part15 testing than their performance as a pulse transformer. Looking at my Rotel 855 for example (yeah, old ), it uses a pulse transformer and then a 2 conductor ribbon cable to the spdif RCA. Nice. Even well done, the clock is embedded in the data bitstream (bad design). Most DACs anymore don't rely on extracting the clock, but people still hear differences in cables when they shouldn't.
  2. other than an xlr will never achieve 110ohm spec. Also to the OP, BNC and coaxial aren't mutually exclusive. BNC connectors are designed to be used on coaxial cable, most of them on specific coaxial cables. Try to make your spdif cable at least 1.5m... longer won't hurt you here.

    Happy Veterans Day

    x4!!!!
  4. Saw this somewhere and hadn't recalled ever seeing it before: Switchcraft EH35MMS Switchcraft Just what Justin needs to keep those pesky 6ga ipod docks from breaking jacks
  5. It's a mini-TRS connector (3.5mm I think... I would check that before buying however). The barrels of many do not allow them to fit. Obviously a custom lock key on the stock cable, but from what I've read, regular mini's are tight enough without it (assuming they fit).
  6. I've done that in the past
  7. Has to be 5.08mm form factor... the PCBs were designed for the Phoenix blocks. I'll take a look, but I was doing a parameter search. It dawned on me on my drive home that I could use the Hirose for the pedja DAC that I need 6, 8 and 2 pos. for, and use the SPOX for the dynahi/dynafet. The 6 and particularly the 8 pin (single row) were what dropped most lines out.
  8. I really don't like the screw terminal blocks much, so I was going to use PCB headers/wire mounted connectors for a couple of projects. I need something in 5.08mm (0.200") or close, and the only ones I have come up with so far are the Hirose HF5 series at Digikey (http://www.hirose.co.jp/cataloge_hp/e67600011.pdf, or the Molex SPOX series at Mouser View List I want something where it is foolproof to take apart and put back together. I need connectors of 2, 3, 4, 6 and 8 pins. Digikey has everything I need. Mouser has everything EXCEPT the 8 pin header (they carry the 8 pin connector... not sure why?). One other question: if I go with the SPOX, you have a choice of brass or phosphor bronze crimp terminals. I am leaning towards the phosphor bronze. Right choice? (started to post this at HF by mistake... removed it)
  9. This shit got damn near hot while it set. And, no, verging on TMI on the superglue
  10. I'd love to see those guys sometime. I only saw Genesis once live, around 1982 or so. I would still say probably the best live show sound and playing-wise I have seen. Awhile back, I had read about these guys... sounds fun, depending upon who they are doing: Tributosaurus: The future of rock 'n' roll? - Chicago Tribune
  11. I wish I could find the two part epoxy I used to use occasionally as a tech. IIRC it was made by 3M. The stuff was quick set and got rather warm from what I recall. Worked great.
  12. I had been hoping to listen to Absorbine_Sr's at Chiunifi last weekend, but his had done the same thing. He said he has super-glued them a couple of times. I wonder if a good two part epoxy might work better? I would agree with Nate that replacement parts would be what I would do as well. Surprised they made these out of plastic like that on a ~$250 phone

    slow forum

    assfisting... nice
  14. Happy Birthday!
  15. My older cat was hit by a car tonight and killed. Glad my two sons weren't around. She was 15 and lived a good long life; we adopted her from the humane society after our previous cat passed away and had her for ~14 years. My wife is taking it pretty hard.

    Fluke 179?

    What Mastech? And did anyone get their VC99 yet? If so, how are they. I could use another decent meter.
  17. Modded units such as? And who modded them and what did they do? Foo foo silver wire mods and blackgates galore, or did they actually do something to them like good output stage, good clocking, etc.
  18. Mini^3 <> M^3
  19. I think it is MG chemicals that makes Q-dope or Corona dope, both of which are HV insulators. Might be another option.
  20. Can you send the PCB back as defective? Conformal coatings are usually solder thru for repairs, so yes, their thermal protection is low by design. I would think it would be enough unless you get stubborn with misapplication of your soldering iron
  21. PMD100s haven't been made for what? A decade? And now someone is introducing a product built using them? I'm not sure what the projected volume of these things is, but 100? 200? I haven't seen any sellers touting having that many of them. Legit? Perhaps...
  22. Colin (cetoole's) stage is zero feedback; jocko's (and all the variants I've seen including the rbroer one I have used) are also zero feedback. I like the sound based on what I've used heard, particularly compared to opamp stages (which by definition use a lot of feedback).
  23. John Swenson posted a really nice overview if you will of async USB on audioasylum which might be of interest to many of you: Digital Drive - Some thoughts on async etc. - John Swenson - October 24, 2009 at 15:23:20
  24. With the sensitivities of this crowd (SP extravaganza, the recent attenuator bust, etc.), shipping problems is not the thing to dredge up...
