Really nice job Marc! Looks awesome, and great job getting it stable.

Normally, manufacturing costs go down (or should) during a production run... continuous improvement and all that.

Here ya go Dinny... a new job! http://www.rudistor.com/call.htm You'll have to give up some of your vile monkey ways, however...

Happy Birthday!

Happy Birthday Mike! Hope you have a great one, maybe a FFF one!

Happy Birthday!

Oh god, not the return of trevor something?

^ Who's doing the board run?

Looks nice Nate! Good to be back "hands on"? I don't see any circles, however

Happy Birthday!

The player has both single ended and balanced outputs, so both need to work. Output jacks will remain wired to the main board. So with his preamp (I presume you know who this is for), the two halves of the I/V stage boards (+ and - signals per) need to be within a mV of each other? Hmmm, didn't know what I was signing up for here May not be a problem as they seem rather close just checking individual offsets to ground, but that is on the bench and just each individual board.

I'm modding an Adcom CD player for a member here, installing a pair of Colin's I/V boards (player is balanced), and am debating on how and where to connect ground on these to the main board and power. These boards have on-board shunt regulators, so I am tapping power from the main filter caps right after the rectifiers for the 2 +/-15V power supplies for the analog section on the main board. AFAIK, it is usually not a good idea to connect more than 1 ground per board. The options I see are: Ground the boards through the power connector Ground the input of the boards Ground the output of the boards Currently, I am leaning towards #1, thinking that noise from the shunt regs, etc. should feed back to the ground plane near the PSU instead of being dumped into the ground plane near the DACs. Ground plane seems to be common between the sections. The one that Colin did (same player) used #2. The stock analog stage is completely depopulated, other than the muting relays. From the schematics, it does not appear that anything else uses the +/-15V supplies. Thanks for any thoughts.

Happy Birthday John! Hope you have a great one, even with the snow.

Sounded like Monster (Beats) was capturing 53% of the headphone market. Further, audio gear sales is 60% of Monster's revenue. What else do they make? Don't cables, etc. count as audio gear? Maybe their cable business is down that much? Whatever.

^ This is the repair guy that we have used for 15 years, and co-workers have as well. His recommendations are usually pretty spot on. Buy basic quality (the guts) first. Only add bells and whisltes if you have to have them. A fridge that the compressor goes tits up on, but still can talk to the internet is pretty useful, no? http://www.allbrandservicenaperville.com/products.html

Happy Birthday Luis!

Nice Chris. I managed to get out for about an hour and 15 minutes on Friday (18 miles). Still old, fat and slow, but it was fun and really nice for January (about 53-54 degrees, light wind, sunny).

Great to hear you are improving Mike. Looks like the right side of your mouth is moving when you smile, which is always a good thing And bitchin' eye patch as well!

Happy Birthday! add what Tyll said as well!

Read the reviews at the innerfidelity link. Forget about making much (if any) sense of most of what is regurgitated at head-fi. Barring that, what jantze said.
