yeah, insane prices. I *was* half interested in some the OEM custom versions, as he will do FRD/ZMA measurements of the drivers.. but I cannot really afford to be interested... so... My next move speaker wise will probably be a long time coming... I was thinking something like the new Lowther TP1 plans for a mono rig, but that's just too insane, even rationalizing that I'd only need one. Those are way cool speakers though, just don't look at the cost of the drivers!

ah. must have been another n_maher http://www.diyaudio.com/forums/showthread.php?threadid=135522 You'd be be surprised what you can do with a small speaker. I have a few builds in the works, one is a 3-way first-order design that's 13.5" high by 7" wide and 12"-14" deep. f3 is in the high 30's with a shallow roll-off...

with some luck I'll be in San Francisco for a conference on Apr.20 - Apr.24. Why not have a meet around then?

that's funny... I actually like low output sources.. I'll try and drive the T50v1 directly with it tonite. I'm guessing it won't be a pretty sight.

Nate: Did you buy any drivers from that guy selling a crapload of Scan Speak drivers at diyaudio? and, no I'm not cyber-stalking you

I dunno about CanJam... I'd rather go out to Burning Amp and hope the cool West Coast guys could coordinate an exclusive Head-Case meet around that time. I suppose I just don't see what the big deal is, but then again, I've never been to a large meet. Plus, what would a meet be without fellow Texans? Lame prolly....

Smeggy: I'll be back in the US on 1/8 and will mail it to you to try out if you'd like. It's a repackaged Teclast T50 that uses Wolfson chipset. It sounds good to me, but another data point would be nice to have. If you're interested, just shoot me your address and off it will go.. otherwise, I hate you .. until I need some custom 'phones, then you're my best friend.

geez Steve that sucks. Somehow I feel personally responsible... just ship them to me here in China and I'll see what I can do I bet the Millet portable can drive them just fine

I think a comparison of he SRM-001 and BHSE with your correction methods would be quite interesting............................. not

you're one strange cat. so, you'd rather have a designer tune your amp to his tastes, rather than have control over this yourself?

If you're using the Scan Speak vents and haven't purchased them already, I have a set I'd like to let go

nice. Feel free to send those worthless "V" grades to me

I vote for wood veneer

I think they are $125 shipped for the older pads, and $150 shipped for the newer pads.

are those mounting plates as flimsy as people say?

each board has it's own single rail supply.

yeah, it was for two group buys. I had the opportunity to talk with Linear several times, as we worked some special pricing on some of the form factors. I wouldn't hold your breath for the p-channel parts. Toshiba just EOLed the 2SK170 this year, so people will start switching over to the LSK170 first then the other parts may come along. Don't forget that the Charles Hansenes and Nelson Passes of the world have 1000's of these rare parts squirreled away. This reduces the market pressure to release these parts. Also, matched JFETs aren't the only kid in town. There are solid bipolar options out there that for example some of the phono stage manufacturers are starting to use.

I bought $10,000 worth of parts from Linear Systems this year. I wager they don't get their act together in 2009. They will release the single version of the p-channel part in question first anyways.

I don't get it. Carry on.

Why does Stereophile post these graphs then? Probably just to fill up space...

simple. you'll have more data variance in the impedance plots and they will be make a much better comparison. For example, one things I use impedance plots for in speaker design is to determine which frequencies the enclosure itself wants to resonate at. This would be interesting data for headphones. I'd recommend looking at D'Appolito's book on speaker testing. It's pretty much the reference on the subject, besides IEEE journal articles.

I'd say pretty hard. Depending on where you get the replacement cable, it will have either foil leads or some sort of stranded wire. The foil leads are damn near impossible to work with. This is the older style cable. Plus is, that they come off the driver very easy. I'd liken this process to doing SMD soldering in its intricacy.

no but head-case isn't available from China. Too many ROFL MAO pics or Jude is bed with the Commies...

that's more like it. Last think I bought was 8 Pass F5 PCBs. I can build a pair of balanced amps with my current heat sinks..

you don't need something like AP. Just download Speaker Workshop and use the play back / recording features built into that. You may need a simple cable with some known impedance, but it should work very well.
