Hmmm... I voice a few constructive criticisms at CA and CC ... and am (predictably) shot down by the CA faboyz. Mr. plisske's remark here is quite demonstrative of the knee-jerk cognitive level of CA's unwashed mass. Again: predictable. Mr. Silberman's presentations are just fine.

Joke: How long does it take a Computer Audiophile forum member (= world-class loser) to screw in a light bulb? Answer: 9 posts

Like I defecated in the OP... I absolutely LUUUUUUUUUUUV the CA like a MF. That said, Connaker is an uptalkin' DICK.But, now that I think about it, there may be an entity at RMAF seminars as annoying as CC: Chad 'Acoustic Sounds' Kasem (the analog hillbilly): LUUUUUUUUUV that Southern drawl, don't y'all

One more thing while we're on the topic of RMAF16 and Chris Connaker ... Here he is being a DICK to the good folks of Boulder Amps: WOW, Dude .... how much did you snort to go off like that?!!!!!!!!!!!

Yeah, I recall that 2015 Silberman video of the same title as 2016. I don't agree w/everything Silberman says but he speaks clearly and discusses interesting aspects of computer audio. If there is a single RMAF person whose public-speaking style I find irritating, it's CA's founder, Chris Connaker. For one thing (whether he's aware of it or not), he way too much. You can watch/listen any of those RMAF videos with CC, and listen to this style. That said, I like CA (this forum and site) and most of its articles and reviews. BTW: I'm not new to ca (lower case) but am "new" to CA.

RMAF just posted their 2016 seminars on YouTube. Steve Silberman (AudioQuest) has a dedicated seminar here: In it, he notes that (after his 2015 seminar??) he got blasted on the "forums" for some of his beliefs/views. Anyone know which forum and/or thread he's talking about? Thx!

Korzunov .... respectfully, I have no idea what your three points (or that CONFUSING linked page ) have to do with the query. It's not about "DSD"!! Single-bit or multi-bit modulation is found in ADCs/DACs that incorporate one or the other in their core architecture. Let's re-state the query a bit more specifically: If the on/off state of each PWM pulse only needs one (1) bit, as per its orig. design, why did some designers feel more than one bit (i.e., more than one amplitude or voltage level) needed to incorporated (i.e., multi-bit delta-sigma)? After all, the old (= costlier and less linear) multi-bit architecture -- i.e., tradit. old-school multi-bit, non-D-S PCM, with all its $$ precision resistor trimmings -- were what TI, Wolfson, AD, Crystal/Cirrus, AKM, et. el, were trying to move away from ... right? In any case, I have found some insights here and here. Alas, these are hardly succinct, as per my original request, but they are somewhat informative. Anyone else want to take a crack?

My students need answers and mine aren't clear and concise enough! Can someone, very succinctly, describe the difference between single-bit and multi-bit delta-sigma modulation? Thanks!

In many ways, you folks are carrying on about stuff that's been covered previously at other joints .... perhaps most infamously by Keith Howard at Stereophile magazine, way back in early 2006 (this was in the print version, too)... Ringing False: Digital Audio's Ubiquitous Filter | Stereophile.com Keith Howard's Ringing False: Digital Audio's Ubiquitous Filter | Stereophile.com Some graphs from the Stereophile article:

I looked at the DX's Manual. If you're referring to selectable sample rate, the Xonar ST/STX has this, too.

Not sure I totally like the newer nomenclature of D/A digital filter ... e.g., RECONSTRUCTION instead of older terms like "oversampling" or "interpolation" digital filter. True, by theory, a lot of "reconstruction" gets done in the DF, but the final waveform reconstruction is done in the DAC. Also, in some designs, a multi-pole ANALOG filter -- LPF, or low-pass-filter -- can follow the DAC output IAC ... I wish more user-level DF control options were avail. for computer audio cards. E.g., my Asus Xonar card uses a PCM1792 DAC (that has the DF built inside). The datasheet for the 1792 notes many functions can be software controlled (e.g., 4x or 8x oversampling, etc.). Certain stand-alone D/A processors do offer control. Unfortunately, Asus drivers do not allow much parametric control over the DAC via Asus's Xonar Audio Center software. My 2011 $120 Colorfly ck-4 iPhone-sized DAP, with a Cirrus CS4398 DAC, offers goodies like user-selectable fast and slow roll off digital interpolation filters (this directly controls the Cirrus DAC). There are a few Asus Xonar user groups that write custom drivers, but none have tackled the DAC chip parameters noted above

You 're at CA, not HA (hydrogenaudio), and are talkin' Greek to THIS crowd. So go to that place for your query ... and don't come back

Higher upfront cost also has the side-effect of album's probability that it will be file-shared (torrented). Apple/iTunes has the right idea ... make upfront (legal) product cost lower than file-share host (or time-cost of waiting for torrent downloads) ... sell a gazillion copies to make profit. Unfortunately, only someone like Apple has the infrastructure (HDD/server farms) to make all this cost-effective. Pono or HDTracks ... these venture-capitalist upstarts may ultimately have to allow themselves to be bought out by Apple, Google or Microsoft to get anywhere...

Scans and artwork ...and liner notes .... Why not DIY ... and much better results than any commercial job ever will offer. Resources: Wikipedia (text, info); Discogs (scans, art, more info); Amazon (reviews, comments) It takes me about 10min per album to put all this stuff in a common album folder. And I only do it for albums I REALLY like. Life's too short to waste on others...

I partly agree with the latter but mostly DISAGREE with the former ... it may very well be marketing on the part of KS/PonoMusic ... but perhaps a lot of (tho' not exclusively) cognitive dissonance and sheer unawareness on the artist end. Some of these artists are not the ... ahem .. brightest bulbs in the pack ... tho' some of these burnouts can play an okay guitar (which itself truthfully becomes an unskilled task after a while ... like cleanly wiping your ass -- with ONE SWIPE --after squeezin' out that juicy turd.) Years ago, Stereophile ran a column called Rick Visits ... (Stereophile writer Rick Rosen visited a noted artist/composer) ... and you'd be surprised at the garbage some listened thru ... here is famous Alan Parson's home system (from Stereophile Jan. 1999 Rick Visits ... article): As the Parsons article notes, he has access to STUDIO gear which should way surpass any gear us HOME-BOYZ have ... so there's the marketing (Greatest Hits CD re-re-re-re -releases with loudness, increasing a bit with every "re-master from original master tapes", etc)
