Marc, Before you leave, could you answer one of questions from post 1247?

Looks good Marc. Just needs a blue LED

I got some resistors last week (Parts Connexion sale), so am still working (slowly) on mine. I am going to socket the gain resistor (R55?) so I can more esaily play around with it. I do not have all the parts yet BTW, so don't expect any fire in the hole from me for some time... I'm trying to build these up as much as possible with stuff I already have. Since I am only using half of the output devices, any recommendation as to which positions on the board to use? At least I think I only bought that many FETs from you Marc? You can tell how much looking in my parts stash I have (not) done...

Happy Birthday Luis!

I keep viddying images of Alex (clockwork orange) listening to Ludwig Van...

Congrats Chris! Sorry about the refrig problems, but that one looks nice. Appears to be a Whirlpool, which should be good. Congrats Colin!

Is this still using the TDA1541A DAC chip in it?

WTG Craig! And yes, this thread has been interesting to follow; top notch work.

I was taking the 19% VAT off for US centric peeps 979 € = $1286 (xe.com) -19% VAT = $1041.66 approx.

b-DAC Features & specs • USB, SPDIF and optical inputs, low jitter SPDIF output • Balanced and single ended outputs, including volume control, drive your power amp directly • Low jitter Tentlabs clock (<1ps rms jitter) feeding the sample rate converter and dedicated reclocking stages • 12 independent supply regulators • SRC4382 upsampler, selectable sample rate • 24 bits 192kHz PCM1792 DAC, all inputs reclocked • -117dB distortion at 0dBfs (thd 0,0006%) • Selectable filters and phase • All functions remote controlled • Striking design, includes milled aluminium front panel and stainless steel cabinet Updates • Expected delivery: next batch mid January, 3rd batch early March • Retail price: € 979 (19% VAT included). Order now ! So, $1043 + shipping if I calculate that correctly.

^ OK, great. See Steve, I knew it would be a cool one

I just assumed you had deleted a 2nd post in this thread by Mr. Buick and if so, I wanted to see it. You did nothing wrong...

I wish Nate hadn't deleted the off-topic post

^ x2. I thought the idea was to differentiate transports and if they have a unique sound signature or not??? Also, on the subject, an earlier post claimed different volume levels from switching transports. I don't see how a different transport or digital input could possibly effect the output level of the DAC, if the same DAC were used for both? Maybe I'm missing something...

Anyone keeping an eye on this one? Might be of some interest... Teddy Pardo TeddyDac DAC review - nightmusic - Digital Drive Teddy Pardo home of TeddyCap TeddyXPS power supply for Naim Audio replaces HiCap and XPS

Happy Birthday to both of you!

Looks good Marc! Me, I'm cooking homemade pizza (well, other than the sauce). California cracker-style crust.

Happy Birthday!

Happy Birthday Jacob! Hope the leg is getting better!

Happy Birthday!

Happy Birthday Aardvark!

OK. My son is looking for some IEMs at under $100... less than $50 would be a bonus. Must have good bass, but I am trying to steer him away from boomy bass crap. From what he has read so far, he seems to be interested in the Ety ER-6is, or the HF-5s. I also want him to look at Shures if he can find something decent in his price range. Also the Headdirect ER-0s might not be too bad, but also might not suit his preferences. He keeps reading crap on the 'net that is all over the map on recommendations. I have really no experience with IEMs, so any recommendations? I know this is way below the $$ threshold most of you look at so...

^ I'll try to update as I go along. Marc PM'd me and said he could answer most of these, and would get back to me. As far as I know, none of the group buy boards have been built, other than it appeared that Jacob built a quad of his. This is probably too low of voltage to attract much attention these days

I have the Eagle files for the thru-hole version but not for the custom SMD version. The files I have are close but probably not the final (don't have the 1x3 pin header for SJ1 for example). Any recommendations for the feedback setting? I re-read the thread and am leaning towards the standard feedback loop (back to the input FETs), but wanted any experience/advice. Does anything need to change parts wise between the two? I thought I would build this with a stock gain of 11 unless others experience would deviate from this. I assume to change the gain I would increase R56 rather than decreasing R55? I think I will socket R56... Also, if the alternate feedback loop is used, how is gain set? Does SJ2 need to be jumpered in this case? Kevin mentions decreasing the 5K resistors to 2K, but I'm uncertain which 5K resistors (R5-R10; R19; R20; R59). I would guess R19-20 is what he is referring to.

Happy Birthday!
