  1. doesnt the resistance vary depending on how far you turn the knob on the Kinetic? the instructions just say "2 to 5 turns" once the resistance wheel touches the tire
  2. i dont know, i have no idea what my power output is. i guess i could borrow power pedals and check a bunch of cadences/gears? i dislike higher cadence, i feel like my legs are flopping all over the place - at least at any resistance that i can do for a long period of time. i'd like to try to get to 90 at the current resistance, but its a long way from 80
  3. i tried the same thing again today just to see if there was any progress before i make changes. i went 4.9mi in 27:35 instead of 4.7mi in 30:00. it took 6min to reach HR 180 instead of 5. the problem was i finished an interval at 27:35 and then was supposed to rest 3 minutes when i had a 30 minute limit. i need to figure out how to solve that problem..
  4. i forget what the name of the Harman or JBL thing was in the slides...the thing that was winning Best Headphone Evar for every test, over the HD800 and Audeze. Was it an actual Harman headphone or just some kind of DSP applied to a HD800?
  5. just got the Garmin heart rate monitor, dont know why i didnt do it earlier first, either i'm using this thing wrong or anyone with over a 44" chest is going to need an extension for this thing to be comfortable I came up with an interval workout based on heart rate with some CrossFit-ish elements; with moderate resistance, maintain 80 cadence until HR exceeds 180, then rest 3 minutes; goal is max distance in 30 minutes total elapsed time. It worked pretty well, i'm interested to see max distance increase, but what i don't know if this serves as a benchmark or something that will lead to improvement. I may tweak it and reduce the rest periods, or increase the HR threshold to 190 edit: the link http://www.strava.com/activities/108463369
  6. I read that and I thought it was funny that the Chinese liked the sound of Beats better than Americans and Europeans.
  7. a subjective only test with 1 person, non-blind, with that many choices? pass!
  8. 2sc3381 would be hard to fake. i dont know any other dual npn transistor that uses the same package that they could relabel. it would be way too expensive for them to make their own fake in that package. so they are either real or they dont actually have them
  9. They sell both real and fake parts Sent from my iPhone using Tapatalk
  10. nice shelly i played soccer last night. my first physical activity outside of a few times the past couple weeks on the bike trainer and the physical therapy work. i wore a hooded sweatshirt and held onto it most of the time like i was wearing a sling. it has been 9 weeks, 4 days since the surgery. my last appointment for an x-ray was 1 week, 5 days ago and i was told i could play in 4 weeks, because i might trip/fall or something. so hopefully just running around carefully is not a problem. on my Dec 7 appt i was told i should be OK to run in 3 weeks, which would have been over 2 weeks ago. afterwards my collarbone was a little sore, but no more sore than it was from carrying a 40lb box at waist level for 50 feet today
  11. the problem with the cheap Stax is they look like they were designed in 1980. maybe it is simply impossible to make an electrostat at that price point without a 5 dollar housing? what they really need at that price point is a design like the Oppo headphone. if they can use Edifier to get the housing made cheap in China, maybe it is possible?
  12. i am 10 speed, i think?
  13. yes, they're arrow
  14. thats odd. verical is the next best price. notice the in stock quantity will be the same as chip1stop.
  15. there's already affordable Stax headphones like the 404, they're just really ugly. Do they sound better than the Kingsound? I never bothered trying the Kingsounds because they didnt fit on my head.
  16. i'll sell the BHSE for $120k each, and i'd like to announce i will ONLY make 24 per year, so get in line now. Also, i will include a femto clock
  17. while the gas tubes look cool i'd probably be unable to use them in a headphone amp, as unfortunate as that is -- inexpensive, so easy to stick them in as no heater supply required. However they are noisier than a zener despite what the internet says, and most of them don't work properly anymore. Some of the later made Russian ones might still function ok but quality is more likely to be suspect. The voltage reference tubes like 85A2 (10mA max) or 5651 (3mA) max i think were still being produced into the late 80s, so those may be a better option, and then increase the current capability with a triode/pentode or a transistor. I have done neither but i suspect it would work better.
  18. "32/768 PCM and DSD 256" we're up to 32/768 now? and i guess 'regular' DSD isn't enough anymore?
  19. i know it takes me a long time to build products that DO already exist, but maybe selling products i haven't even started to design yet is the future
  20. regain 100% of left arm/shoulder strength in the next few months, rather than the 70% average that people get back meet or exceed my crossfit top performance from 2010-2011 run a hand-timed 4.6 40 yard don't crash on a bike
  21. you can get a better price right now from chip1stop. for 50, $0.94ea. but spend $60 and shipping is free, otherwise its $6. never bought from there before but they are linked to Arrow so it is safe
  22. actually the only cables ive ever seen measure different, as far as distortion or frequency response, are ones that intentionally roll off the treble
  23. obviously, a cable can be lower distortion but it's not going to show up on distortion measurements. it's some other kind of distortion that humans don't know about. only ears can detect it.
  24. not sure, but all the Renesas ones ive seen including the ones that B&D sells are 2SA1486-AZ
  25. it's news to me
