Thanks guys. The video was interesting, to say the least

Does anyone have schematics for either the Gold (balanced?) or the unbalanced version of these? I told a person I dealt with (diyaudio user) that I thought they might be available (and told him why bother), but his interest is just in the front end section as a preamp). I saw what is available on the eservice info site, but can't remember my login there. The user says he has some incomplete schematics with pencil markings on them. I had the attached jpeg, but think this could be what he already has. Thanks for anything you can find.

Kinda what I was guessing. Thanks Kevin! Sent from my iPhone using Tapatalk

Thanks Michael. Actually, I was referring to the pairs of holes for the 10M90s I believe on the Carbon boards themselves (top of pic, past the two resistors).

FTFY

Stupid question time, but what is the purpose of the stacked holes for the HV part mounting? Not the best pic, but best I could find.

I’ve been presented with the possibility of acquiring a Pro-ject RPM 5.1. Anyone know anything about these? My current table (which I haven’t used in years) is a Thorens TD-320. Any thoughts appreciated. Sent from my iPhone using Tapatalk

Since my son is studying audio engineering, works in a studio, and has one or more interfaces, I asked him if he had heard of Metric Halo. He hadn't. I'll have to show him these.

Happy Birthday Dan!

Still trying to wrap my head around all of this... so these things are professional audio interfaces, and you guys are using them as your DACs in your home systems?

A nearly 3 month old thread... you have your 1st post and you recommend something that was already recommended back in early December? Not a good start.

Curious... I’m building a Carbon for a European user and don’t have any Stax to test it with. If I can’t find a pair I can borrow, which one of these would you buy: the Monoprice, or the Kaldas Resaech RR1s? Sent from my iPhone using Tapatalk

Hehe... that is the exact reaction when I brought one of the SS Mini's into work with my Fostex's. When I plugged the headphones in and then had to plug a cable from my phone in, my boss said "Oh, no Bluetooth?". Then he listened to it and said it sounded really good. But in a sort of non-understanding way...

Most of the people I work with in a tech company think whatever Bluetooth shit you buy at Best Buy is the end-all be-all of the best sound you can get. They don’t even really comprehend that it could be better, and frankly don’t care. 128k MP3s are just fine with them. Sent from my iPhone using Tapatalk

Bought a used Oppo BDP-103. I'll let you know what I think once I get it.

Happy Birthday Colin! Hope you have a great one! Sent from my iPhone using Tapatalk

Not sure, they might work. I took a look on diyaudio. Not much discussion or mention of the BF256C. I did find this: alternative transistors, not as costly as the Toshibas SK170 and much easier to source could be the BF256C and the BF246A/247A. The former is a bit higher in noise (still sufficient for highlevel circuits), the latter features much higher Idss which allows for larger source resistor values and for higher bias currents, which could be advantageous in output buffers and buffers that need to drive capacitive loads -which is a very common case with filters. https://www.diyaudio.com/forums/analog-line-level/169005-jfet-active-crossover-3.html#post2227453 EDIT: and from earlier in that thread from the same poster: well regarding soundjudgements aren´t easy, because everybody has a different taste. To me all OP-Amp filters I built sounded artficial to a certain degree. I never doubted to listen to a reproduction of music. The first discrete JFET-filter changed that. Now there was music a lifelike quality which sounded authentic. Music instead of HiFi. I know that distortion-wise the simple Buffer is very good, but dosen´t reach a OP´s low values. But the...who cares about distortion figures, which -as we know for 30 years now- don´t correlate at all with the sonic impression? Noisewise even the BF256C settles around -100dB, the BF246A, 2SK373, 2SK170 beeing even better. So noise should be no big issue. Hum can be an issue in every circuit and typically it depends alot more on the circuits surroundings than on the circuit itself. A different thread, but doesn't sound promising: https://www.diyaudio.com/forums/pass-labs/145201-building-symmetrical-psu-b1-buffer-230.html#post2794067 I'd probably just go ahead and try them, observing pinout, but without the correct part or know equivalent, it might be hard to tell.

Pics or it didn't happen...

Happy Birthday Jeff! And, yes, that does look like Jeff's lake by his house once he gets done with it
