Paid, thanks!

Boards received. Many thanks!

Sorry to say, but I closed the GB and placed the order a few days back, and for various reasons its not possible for me to add more pots to the order (I've sent you a longer explanation over PM). I'll refund the paypal payment as soon as it shows in my account. However, if you look in the audio gear for sale post, I think JohnWMclean posted a bunch of different quad pots for good prices yesterday (an updated spring sale post), so I would recommend having a look there unless they are gone already. So, it turns out that TKD just now are changing pin size for the 2511 because they are switching production materials for the internal pot PCBs. The former type (green color) has 3.0mm width terminals, while the new type (black color: injection molding) has 2.5mm terminals. We will get the latest type for our 2511 order, so 2.5mm is the correct pin size. Advice on the change of the resistor board 3-1.pdf

Will do!

I can ask, but I got the CP2500 data sheet directly by e-mail from TKD when discussing pot setup, and it's same as the one posted above, indicating 2.5 mm pin size, so I think that's what they think it is now at least I have a 601 that was produced in may this year, I can check pin size on that one one I find my caliper and see if it matches the data sheet. update: I've measured, and the 601 does indeed seem to be 0.8 mm pin size.

Better safe than sorry in this case I think...

Funny, I have started to think along those lines too but was a little afraid to say it, because I don't have the filter math skills to back it up I realized that the effect is recognizably similar across what must be very different recording rooms. I guess that makes it more of a reverb effect than anything else. If it comes from interaction with the dither as you suggest, its character would then be defined by dither type rather than recording room properties. Fascinating thought.

Savor the moment Happens way too seldom for me... I think it's brilliant marketing; if you're not into filter math/theory it makes the competition look like approximating amateurs . That said, I prefer it to others for stuff recorded in something bigger than a studio booth. Good for the perception (illusion?) of space.

Ayre's take on why apodizing, min-phase, slow roll off filters is where it's at and what they prefer. Should be the same as HQplayer's poly-sinc-shrt-mp. https://www.ayre.com/white_papers/Ayre_MP_White_Paper.pdf

STATUS UPDATE: TKD has confirmed the GB order including the pots with extended shafts, and started production. So now we wait

Well, it's only been a few hours of listening, but I have come to pretty much the same conclusions. The closed from does something with the room presence, the room gets smaller but the sense of space is stronger. The poly-sincs have better bite, but a little less "in-the-room" feeling. I guess it comes down to what music it is and where it was recorded. For me, current conclusion is closed form for jazz, chamber music and live concerts from small to medium size venues. Poly sinc for stuff with lots of electronica in it. It's wonderful to be able to choose I should add that for me, it takes the high end gear to make the distinctions. Carbon/007 yes, HD800/Sysu Dynalo yes, HD650/M3 no...

Went down the HQplayer rabbit hole a while this weekend. Brilliant piece of software! Many thanks to @Sherwood for posting this! Soon realised that Jussi (the coding guy behind HQplayer) implemented a closed-form filter a few months ago, the merits of which Schiit has devoted a long section of their Yggy FAQ to. Pretty much the secret sauce in the Yggy. So for anyone who would like to try that sauce without buying the Yggy, here's the free trial option. Of course, a DAC is so much more than the filter and algorithms may differ, etc but it makes for a very interesting listen. Found a nice explanation on the merits of closed form vs apodising filters at http://www.computeraudiophile.com/f11-software/hq-player-20293/index147.html#post475586

Ok, not so long evening, a bad solder joint it was. Nice and steady at 120 ma now. Guess I have to go watch a movie instead. Boring Many thanks for both of your very quick responses!!!

Great, thanks! Can't get more than halfway there, so I've screwed up somewhere... Makes for a nice evening of troubleshooting

Just double checking: 120ma, not mv? Can't get near the ma version, so thought I'd ask before pulling things apart...

The POTs section of this GB is now officially closed. Entries for pot boards (type and quantity) can still be updated and edited. Also, if you need your shaft(s) extended, now is the time to make that known I will be placing the order tomorrow.

Great, thanks!

Well, I can't help but feel a bit cheap when advertising shaft extensions for a small fee

Done. Regular will be the default option if no choice is indicated. I agree Those who want extended shafts, please indicate so in the spreadsheet.

14 mm above the threaded part for 4CP-601, 10 above the threaded part for 4CP-2511, if I remember the data sheet correctly.

Good news; customized shaft lengths can be had at an additional cost of about 1 USD per piece, and min quantity is 1, which means @UFN can have the length he desires without that affecting anything else. Bad news (for GeorgeP): custom thread length was not possible. UFN: please tell me how much extra length you want for your pots. Anyone else who also want longer shafts; let me know. I will close the GB tomorrow. Those who have not paid but who are still interested, please make your payment.

A good argument in favor of big knobs . I like it. I'll ask TKD then if our GB could have the option to do a slightly longer shaft, and report what the conditions (number of pots) for that would be.

Noted. The first step is to ask if they can do what @UFN wants, and what the minimum quantity is for doing that. If enough are interested and minimum quantity is low, we might make that an option. I usually do thinner panels than 10 mm, so some portion of the GB will definitely be standard length.

Not yet; there's been quite a lot of PM discussions on details and custom values that I need to ask TKD, and I though I'd put them in one e-mail rather than shooting a barrage of questions. Since you found that they do can special length shafts, could you tell me a little more detail about what would you like to see extended (given that we meet their minimum quantity requirement for this) ? Would you only like the threaded part extended so you actually can fit a nut on the other side of a 10 mm front panel, or do you also want the shaft extended (and if so by how much), or would you rather see both extended (and if so, by how much for each part)? For my part, I usually countersink from the front or tap from the back of the front panel when it's 10 mm (the latter takes a couple of washers to get position right, but works surprisingly well), but I can see the advantage of not having to do either of these
