Why use the 6CA7 again? I don't follow. not the PA42, but stumbled upon plenty of these for beans: http://focus.ti.com/lit/ds/symlink/3583.pdf I was more curious on how it compares to the AC coupled amplifier.

might be worth it for you to hold one of those cool wires to your right temple and one to your left temple for a few seconds.

what about this one:

I've charged mine a couple times already. Works great for me, just need to raz them about the wierd-ass power connector on my Chinese DAP and see if they'll make good on providing "any" connector ")

I really love the upper register, so I wouldn't add a supertweeter. They are too hard to integrate well and I don't like the phasing complications they introduce. Most designs are pretty much flat to 20kHz and go around to 45Hz all at +-5dB or so. Case in point, the Alerions. Good enough for me.

here's the original I'd love to try a Lowter driver at some point, but they're amazingly expensive.

Is the GES the AC coupled version, or the DC coupled version? Also, how does the AC coupled circuit compare to the DC coupled circuit soundwise?

not even the TP-1?

what, does it have some sort of solder prevention circuit installed?

try adding a parallel resistor from the wiper (i.e. output of the pot) to ground see if that fixes the problem.

assuming it wasn't the crossover that went out does "blown" mean it doesn't work, or "blown" mean it's distorting.

Thanks Rodrigo I'll see if I can find someone else to help.

ok, in theory you may be correct, but why the hell would I want a player that does this to like 99% of my source material? I'm not going to get a whole new library of material that sounds better with my new shiny player... Also, I find it odd that this so-called "compression" seems to happen with the same DAC chips, over and over.

I don't attribute this to compression really, as I've done A/B comparisons and it's never been the source material.

Does the PCB contain a protection Zobel of sorts?

I dunno about that. They seem to retrieve detail that couldn't have possibly been there to start (I don't mean that technically, I mean that it *seems* that way), especially in the 4kHz+ range. I'm a detail-head don't get me wrong, but the a lot of these newer digital devices seem to pull it out of thin air (well, I suppose that's somewhat close to the truth). I've just confused myself re-reading this.... anyways, what I mean is the hyper-detail is not natural at all, in my opinion.

I have a question for the Spanish folk Do you ever place orders to Conrad.de? If so, would it be possible to add an item to an order? I cannot find a way to send to the US from their website.

Well, in my opinion the Japanese X386S (if you can find them, and.. really, they are big) are probably the equal of the Black Gate WKZ, in circuits that I've tried them (PSU). At this voltage, they are probably one of _the_ caps to beat. I dunno about the cathode bypass caps, as I avoid them where I can and where I cannot, I have pretty small voltage and have found polymer caps to work better than anything I've tried. I don't really have the experience that Doug does here, so I'm sure whatever he recommended would be worth trying. I will say if I had to just try something, since I don't have much experience with this amp, I'd start with a Mundorf M-Tube Cap 47uF/600V or 30uF/600V and bypass it with something like a Relcap RTX.

What's the general topology to need a 250V cathode bypass cap? My recommendation for the PSU would be the _Japanese_ made ASC (made by Shizuki) X386S capacitors, if you can get it to fit.

Would that be Barium Cobalt Nitrogen wrapping? Didn't check the periodic table, but I think that would be BaCoN

I prefer skipping the freezer and just going straight to the cryo chamber. duh.

I pay $26/$1000 on house + land. That's on the low end, definitely.

Just curious, what's the cost of living index (COLI) difference from say your current location and Austin, TX? Housing prices are on the rise here and food isn't really cheap here either. For example, where I first lived there wasn't any fast food restaurants within 5 sq. mi. and our average monthly grocery bill doubled. I know it's not NY/CA/DC/etc. but I'm curious nonetheless. Housing for typical middle-class in north Austin is around $100/sq ft. or so I'd estimate, double that if you move more towards downtown.

yes, or to piggy back the resistors on top of each other on top of the board. Now that I think about it, perhaps this is fine, but I think they could be moved slightly apart.
