I'm an electronics engineer and an audio enthusiast - and I find Paul's answer very convincing. Same goes for the approach they took at PS Audio to building a great non-compromise DAC solution: while over-sampling solves most issues with phase distortion in the output filters, the FPGA makes it powerful, very flexible and future-proof - making a great value for the customer. I feel inspired.

I upgraded my modi 3 dac with the iFI I power supply and I couldn't believe the difference in sound then added AQ cables rca and toslink and for all tolD of 238.00 bucks total for all amd it sounds amazing !!! It beat out my first dac that's was 400 bucks sounds twice ad good ! Power supply and cables matter !! Just dropped my review on it I call it the Mod-E-Aud-E-Fi Dac lol

Yes, 7k for the best and a bit less for other models, both worth their prices with plenty of attention by one of the best in the industry,Ted Smith. There are plenty of KZfaq vids covering their attention to thieir theories and execution. I don't see many companies explaining what they do. They even offer upgraded boards with newer tech for some of their models. So they are still paying attention and helping you not over pay for a whole new DAC whenever possible as the tech. evolves🧐

@@LuxAudio389 There is, almost always, a way to improve, something. Saying this, how much time & effort, $, are you willing to expend? SACD / DSD, is supposed to sound like, `The master tape.' I've heard - some - excellent consumer products, beginning with high quality reel - to - reel tapes {many were, however disappointing}, through some high quality cassettes & vinyl albums. With 2 lenses - as the McIntosh has - the PS Audio CD Transport should extract a high quality signal, into the high quality DAC. One thing, not mentioned, is that, in addition to the theoretical advantages of these separates, keep in mind: I've purchased both the top, PS Audio CD Transport, AND the DirectStream DAC - no space between `Direct And Stream!' Separating these two words, is very incorrect and, I feel, Naughty! What is not mentioned is: the list prices are about: $6,500 & for the requisite PW DirectStream DAC, no space again, at list $5,999.00 / $6,000, plus recommended, the Network Bridge II, with this las, a total of: $6,899 / $6,900. The list price total is therefore, ultimately, a total of: 6,500 + 6,900 = $13,400.00. You may, or may not! Say, "Ouch!" Did I pay this much? No, because there was a recent, one - third off sale on most of the PS Audio Company Gear, which I took much advantage of! Irresistible! You're smart, figure it out! And, right now, right this moment for a few more days, there is actually a slightly better deal on the PS Audio CD Transport, for just: $3,999. BUY NOW, RIGHT NOW - OR, REGRET! YOU BET!

At the end of the day however, audio companies use off the shelf DAC IC's from companies like Analog Devices, Ti and the ilk and so any differences in sound quality is determined by associated support hardware. Obviously this rule is broken at the true high end as Paul says using FPGA's or DSP processors.

The biggest problem I have had in the scientific community in precision instrumentation, is not the logic, but the quality of the R 2R ladder. Upsampling is fine and can be fed to an off the shelf PCM type DAC with all the benefits, plus the high precision of a mass produced and very precise R 2R ladder. I'm surprised Paul didn't even touch on this subject. Paul, are you building the ladders from discrete components or from a resistor network manufacture? For the best linearity and precision, modern DAC chips are very precise. They handle upscaled data just fine. It is almost impossible to produce an FPGA DAC that can outperform an off the shelf 24 bit DAC produced for the scientific community to their standards. Analog devices products are very difficult to match with discrete components. They are used in the semiconductor industry for positioning the steppers that are used to align layers in a semiconductor IC. Precision is essential in this application.

Hi Paul, so can a mediocre CD player be improved by adding a DAC down stream, since it (audio) is first processed through the player? Thanks
@kwacked1
@kwacked1 6 жыл бұрын
When I bought a good sounding system the very knowledgeable salesman explained that a CD player has the “transport” which is the part which reads the CD and then the DAC which converts the digital signal to the analog audio signal. A manufacturer might use the same good quality transport in different CD player models which sell at different price points. Using an external DAC will bypass the often poor DAC inside of a mediocre CD player and use the high quality external DAC instead. So I followed his advice and it sounds great. An additional point is that two different kinds of cords can be used to send the digital signal from the CD player to an external DAC. The first is optical and is called a Toslink which probably won’t sound so good. The digital signal has to be converted from electrical to optic and back to electrical. Every conversion makes the sound a little worse. The other type of output Paul mentioned is called digital out and uses a digital coax cable. This can sound much better because it bypasses the extra conversions which have to be done if the optical output is used instead.

All amplifiers sound the same as long as they are driven in linearity with nornal to high volumes with average speakers. Modern digital players are the strongest link in every chain, the weakest room, positioning of and the loudspeakers. Modern digital players are all equally good enough that no speaker in the world can outplay the technical superiority of any electronics by a factor of 100 or 1000 at least. Digital room correction do not correct everything. Vodoo again.

Yes and no. The digital player may be the strongest link, but the digital format itself is the weakest link. Not the player, but the CD. The sampling rate is too low for the highest frequencies - which are too low for audiophile standards. 20K is not the limit of all hearing, it is the limit of the average ear. Which means half of us, especially younger people, can hear beyond 20Khz. But there's absolutely zero beyond 20KHz. There's nothing to restore, nothing to equalize, no way of getting any of it back. Look at TV and video. From NTSC to 6k, how many times have we been able to upgrade our media libraries? (HD, DVD, blueray, 4K, 6k) Now how often have we been able to do the same for our audio library? (um, once - but it's not available for most music). While I admit that almost nothing happens at 20Hz, we're still technically capable of extending the CD below that. I'm not concerned, but some others might want that. But I certainly want digital audio extended to at least 24KHz and possibly up to 28. Second, while digital is certainly capable of excellent dynamic range, everything that has been remastered in the last 20 years has been compressed. The latest stuff to come out has almost no dynamic range to it. Trying to restore the dynamic range heard in the studio requires such extreme processing that it introduces audible distortion. While the hardware may be the most capable part of any system, the media leaves a lot to be desired. And the way the media is engineered these days makes it far worse.
