better source?

Dusty: The other option is, "they don't scale" but sound good with everything. To me, the question "does it scale" assumes that there is some combination in which they don't sound good.

Despite almost single-handedly dissolving Head-Case, I have no real power. I have a feeling they'll take away my plastic shovel now that they know I have one

My $0.02. I think the you'd better be served by investing in a source, rather an amp. From what I've seen, IEMs do indeed scale up to a great source, but I'm not sure at this point I can make that same argument for headphone amp.

don't worry about me, I unfortunately only wield one of these: It's the others you have to worry about.

talking about bans after 13 posts is not always the best idea...

I'd like to get on the DVD list for season 1 if there is a line forming somewhere...

The worst thing about LTSpice is the schematic capture. Can your CAD program export a netlist? It might be easier to work with it in text form (this is what I do) and bypass the schematic capture program. If it helps, I can upload you a high voltage regulator circuit that I put together (and subsequently made boards, so yeah it works) to play with.

I think Reks is referring to a different "slow", as in write speed.

Tinned tobacco seletction is a third of what it was 2 years ago around here. I hope Dunhill gets back over here

fair, very fair...

actually, they look like DX55's. The frame was the give-away.

Wanna bet? My money is on Feastrex

I'm planning on placing an order at TAW once they get their website up and running again, if perhaps anyone needs some Wima caps...

We have released DipTrace for Mac OS X (version 2.1.0.7). http://www.diptrace.com/downloads/DipTrace.dmg (128 Mb) This is Freeware (300 pin) edition, however it can be converted to any edition or trial with your registration key. It also requires right mouse button as this is originally Windows application.

In my opinion, the 840c has sort of an artificial resolution or detail. It doesn't sound right, almost like it's trying too hard to be resolving... hard to say, but it's not a realistic detail at all. So, I couldn't really call that a strength... imaging I could agree with.

they do in fact burn, given enough frustration and a "evil slip" of the bench supply. I can confirm this.

perhaps more capacitance is needed on the amp side to swamp out the effect of the umbilical cable?

yup, I put in a -12v regulator. I measured it again and it was -13.8V and the diode is flipped (with regard to the silk) on the -12v part (which is closest to the edge of the board). The part I used is 511-L7912CV. Regardless, the -12v regulator I got from ST is the annoying (new?) single gauge type with the paper thin tab. Since these devices aren't putting much out, I'm thinking about using plastic parts here as well (511-L7912CP and 511-L7812CP)... strange though, first time I've ever used ST regulators... once I get a connector installed there, I'll put a load on it and see what happens. oh and the other half of the board works as well

Yay Steve! Can't wait to see more pics!

CSS is a typo. I'm not a huge fan of Raisinets unfortunately.

Cannot load that schematic on my phone, but I'd guess that rail voltage difference is inconsequential. Assuming half of it drives a CSS which would have a change in the nA probably... I wouldn't assume more components is better than a good adjustable regualtor though, given how good those have become of late, when properly implemented.

Looking at the info, I wouldn't worry about remounting that transistor... You might cause more damage than it's worth in the removal process anyways.
