That is very exciting - I've thought about maybe ordering JH13s eventually, but I have a serious aversion to spending more than $1000 on anything sight unseen (or sound unheard, as the case may be ).

It makes perfect sense if you're looking at the ground leg deck of the attenuator at the full-attenuation end. A ladder attenuator with 2dB steps starting at -60dB would have at least 10 resistors on the signal leg side that are equal to the nominal attenuator impedance. The photo has 10...

The Gamma2/Y2 DAC is definitely going to be there. I've been listening to it for a couple of weeks and for its size and cost it is amazing. The Mini3 and CK2III should be done by then easily if I don't blow anything up (boards are done, just a bit of casework). The M^3 is a maybe at this point...

This is very exciting... I've been wanting to build a fancypants microcontroller control for a preamp myself... now I just have to decide if I'm dumb enough to try to cobble together my own rather than using you guys' fine design.

When I did this for my K501s, I ordered from Redco and got a Switchcraft 131 female 1/4" jack. I used Mogami W2893 Mini Quad Mic Cable, which I like fine, but it's not quite as flexible as a stock cord. I left mine bare.

I have been working on Frontpanel Express panels for my Gamma 2 prototype. I will send the Frontpanel Express files to anyone who wants them once I have gotten my order and made sure everything fits, but obviously I will not guarantee that everything is correct and you use them at your own risk...

Maybe the cable does come with the PS3... when I got my PS3, I hooked it up immediately with an HDMI cable and would've just stuck the AV adapter cable in a drawer somewhere if one was in the box. I don't remember now, it's been a couple of years. I'm about to build a second Gamma2 DAC to use...

Gotcha, sounds good.

I have never used nixie tubes, so take this with a grain of salt, but every tube I have ever used takes a DC power supply. Given that pin 11 is labeled "anode" (i.e., takes a positive voltage) I would assume those ones take DC also. I don't know if the number pins should be connected to...

Sorry for the delay - just sent in my $10. I'm looking forward to meeting you guys.

Does the crossfeed work on both outputs or just the headphones?

It's not like headphones won't produce sound if your source can't supply enough voltage to get them to 100dB, they just won't be 100dB loud... if the phones are hard enough to drive, your sound card may not make them as loud as you would like, but they will otherwise work. There are a whole...

DC offset is a "Bad Thing" which can damage headphones, so it is important to measure if you are unsure of your equipment. 2V RMS may not get some of the high-impedance not-very-sensitive headphones loud enough or drive them quite right... somebody else will probably come along and give you a...

I really like my CK100s but I have not heard the other two IEMs you mentioned, so that's not much help. If you want to listen to pulsing bass, the CK100 is not for you - if you want to listen to music with the bass where it belongs and not walking all over everything else, they might be a good...

It sounds like you are measuring DC voltage. You're not going to get anything useful that way (An audio signal alternates + and - and so, in DC terms, averages to basically zero. It alternates fast enough your multimeter doesn't display the changes). If you have a good multimeter, you might get...

Also if you get a different transformer, make sure you get one with enough power capacity. The specified Amveco is 7 VA (30V * .233A = 7VA).
