What's up with dynafet boards these days?
kevin gilmore replied to Icarium's topic in Do It Yourself
You have seen the USB turntables right??? Some of them are quite expensive. A/D conversion, then RIAA in the digital domain... Ummmm... those ICEpower amps sure sound pretty nice for the average J6P and even for some of the non-average types. what about those new ionovac things that run on a 50khz square wave... hdmi connectors won't fit thru a standard garden hose... Also won't fit thru a standard conduit either, which is why i'm using hdmi to dual ethernet converters. -

Well it makes sense right?? isolated ultra speed digital delivered to the amplification device. true analog step attenuator after the dac controlled by the CEC channel. No ground loops ever. No more stupidass discussion of expensive interconnects... Of course we will still have power cords to argue about, but i see that finally taking a back seat to everything else. -

Yep the end of analog! Most people aren't paying attention that from now on, all audio, not just the surround sound stuff is going to be digital delivered over hdmi. Things are going to change and there is going to be lots of new product. With lots of bugs. -

still waiting for linear systems (or anyone else) to get off their asses and start selling dual matched complimentary front end fets. After that, lots of new stuff. Of course the world really does change in the middle of february. -
There's something wrong in Colorado...
kevin gilmore replied to n_maher's topic in Headphone Amplification
Its called ONSTAR. More than a car phone. In your neck of the woods, on every single SAAB for the last few years. The point to point units are really the only ones easily repairable in the future. Elphas, where is your second amplifier... -

this is the post in question FS: Singlepower ES-1 - Head-Fi: Covering Headphones, Earphones and Portable Audio tyrion should contact that person directly and see what his answer is. then i will post what others have said that person said. But here is one of them That amp, like all the other ES1's out there definitely does have a problem and will need repair for sure. The person above is giving out my name, work, home and car phone numbers, and mailing address. Without my permission. Jude received a copy requesting that this person cease and desist, but if he has done something it has had no effect. In any case, circuit board mpx3 versions where the parts have burned most of the way thru the circuit board cannot be fixed reliably. Pictures can certainly be provided. Looks like i'm in the singlepower repair buisness. People are evidently getting a great deal. -

For stuff priced at these levels, A single set of mil-spec amphenol connectors should be what is used. No way to plug it in wrong. Here is a better one though. How about every single box has no ventilation whatsoever, and some of the units internally dissipate 30 or more watts. Its the reason the circuit boards are turning brown from heat. -
What's going on with HeadRoom?

purple is not my color They actually pay me for this. Make sure it is a private school. They pay better. -

Some companies are run by selfless, fearless, morons in birthday suits. Or at least barely fitting underwear. Beat you to it i did early retirement in just over 4 months... (if i wanna) -
I'll wait for the oppo. But if the krell dies in the meantime, i'll get this SONY SCD XA-5400ES SUPER AUDIO CD PLAYER, XA5400ES which is getting rave reviews and whose stereo performance is being compared to meitner and dCS. Have picked my new projector for the media room (jvc rs-20) now i have to find a processor/preamp that meets my requirements, currently there aren't any. I want pure native dsd over hdmi with analog volume and balanced outputs. But clearly a player that puts everything on the hdmi connector is the wave of the future, and finally someone with brains can do an ultra high resolution native dsd dac, and then when the player craps out, you throw it out and replace it without having to spend $2k to $3k for a new $149 piece of plastic.

solid state and all discrete might be nice. and appropriate for a product priced up there. -
Might interest the rich ones..
kevin gilmore replied to ZephyrSapphire's topic in Home Source Components
No native DSD. No hdmi input. Pretty useless. -

jaguar was in the shop 41 times in 39 months. Never again. Some of the parts were on their 3rd replacement. (the autoleveling headlight assemblys at $1400 each) (requires removal of entire bumper) Its a distant memory that is fading. It was all under warranty, but the half a day in the wrong direction every time to take it to the dealer got old quick. It was a great deal of fun when it was working right. Corvette has yet to be in the shop for repairs in 27 months with about 23k miles on it. Other than oil changes, the only replacement part so far was the cabin air filter. And trust me, i don't drive it like a little old lady. So far on the CTS, only a firmware upgrade to the nav system. (xm live traffic update gizmo that has software bugs galore)

If it is a 6 pin plug it is low bias only, and will only fit into some of the older amps with both regular and pro sockets.

A single gain tube and a cathode follower is a SOTA preamp You kidding right Ray gets to fuck up the electrostatic market with his bullshit. OH JOY. I guess that there is nothing left that is sacred anymore. WOA... just found this one. Billy just has to have it. Auction on thursday... http://www.doa.nc.gov/ssp/auction/Item%2078.jpg -

Billy i think you reading comprehension is a bit off again. I said that i thought you had nothing to do with it. If i had thought otherwise i would have contacted you directly. The only way to win is not to play. knuckledragger, thats a great picture. -
You have no idea. My biggest superconducting magnet is about 12 times more powerful than that thing. And its gap is 3 feet long. if you want an isolation system that really works, you really need to go with a pneumatic system, or pneumatics and active piezoelectrics.

yep, some of the usual suspects have added their twist to the thing. It will be a sphere, of about .35 inch thickness. It will come apart. The finger holes will be removable. Then i can put a small robot into the thing. Perfect 300 game every time. Trouble is that it is going to dent quick, and the halves will probably not unscrew too many times. May need to change from screw threads to an inner ring with flat screws.

ultra trendy aluminum bowling ball it is. Start by cutting the block in half, use the NC lathe to cut out spheres on the inside, tap and thread to put the thing together. Then machine the outside to perfectly round. Add finger holes, tap the holes from the inside, and use machined finger tubes. If i calculate everything correctly it should end up the correct weight. Anodize or paint....

OH i have some delightfully evil people here. Aluminum or magnesium bowling ball. Painted black to look like the real thing. Take it to a bowling alley and try and use it...
-
from here Calculation of density with tungsten 1 cubic foot of tungsten is 1200 lbs. The diameter of a standard bowling ball is 8.6 inches... So a 10 inch cube would be the minimum. electromagnets are very inefficient. Its the reason superconducting magnets exist, because there is no other way.

I've been seriously thinking of making some of my own tubes. I used to make them back in the zenith days, and i did hand made plasma stuff at lucitron. It is actually pretty easy, and i do have access to a really nice glass lathe.
