[RT] ASUS Introduces the Essence STX II and Essence STX II 7.1 Sound Cards - Page 14

post #131 of 231
Yeah, what's claimed is 124 dB SNR (so some signal level referenced to the noise level). That's a ratio of two electric signal powers, not sound pressure. You're not measuring with microphones for that. Note how it doesn't say dB SPL?

Now, whether or not 124 dB is actually true or not is a different matter. Many companies are in the habit of quoting chip specs in optimal conditions, where their actual products aren't reaching the full performance of the chips. And here with an internal sound card, the actual SNR you get is going to depend on the computer you put it in and what else is running, as it doesn't take much to bring down an extraordinary ratio like that.

...not like you need anywhere near 124 dB for playback, seeing as noise from the electronics at that order of magnitude and a couple higher would readily be drowned out by ambient noise and noise in a recording in practice.

I am currently using a Pioneer SC-79, and a Ti HD, as in-/outputs, McIntosh solid state amps, etc. I have yet to hear a single speaker wire that sounds better than the 12AWG OFC I get from Monoprice and sleeve w EMI/RFI resistant sleeve and connect with Monoprice banana plugs.
Ihave plenty of recordingside equip ment, and a lot of variations on the above mentioned.

I don't care about bragging or "equipment compensation", I only say this to give an indication of what I use day in and day out.


That said, I think "audiophiles" are comedy gold. Onthe production side, there's a reason for recording, editing, and mixing at 32bit depth and 96-192khz, because it makes it easier for us to identify and remove or correct errors. The best possible analogy I can give is that it's like having two separate computers, identical in every way, each having its own 3840x2160p 32" display. On one, it's running a game with say FXAA/SMAA + 4xMSAA. The other, same game but at 4x4 Super-sampling. I will argue that the difference between the two is imperceptible, provided you are a normal person and like to enjoy games rather than dissect the tiny visual flaws.

However, if you are using the computer for graphics design, suddenly the ability to scale and re-sample the image makes it easier toiimprove the quality for everyone.

The same thing goes for audio work. I don't know a single fellow person in pproduction who claims to hear the difference between 92 and 192khz, or that there's an audible benefit from 32 over 24 bit depth. Using frequency response analysis and so forth, however, the slight variations can be corrected VISUALLY and thanks to downsampling, without a ny loss in quality or even the ability to tell it was altered.

Regarding 124dB SNR...
It is pure, unadulterated marketing.

If you want to know how loud that is, I can give you an example...
I have a Noveske billet receiver short-barrelled AR chambered for 300BLK. 10.4" Barrel, 11.5" free-floating rail, Magpul CTR Stock, Tangodown battlegrip, Troy HK-type BUIS, Giesselle SFA trigger, Magpul PMAG II'S, Surefire G2ZX 500/25lum dual-mode weaponlight on a DD Offset mount, Troy mid-sized VFG, EOTech EXPS3 holographic sight and G33 3x magnifier both w Troy QRS mounts, and currently an AAC Blackout muzzle brake.
The 300BLK is designed as a 30cal AR round requiring only a new bbl, to fire from a short barrel better than anything else (my own 10-16" 556 AR's firing at 2485-2830fps don't have the accuracy of even a 9"bbl 300BLK), and which can be loaded with bullet weights ranging from 110gr to over 220gr for both supersonic and subsonic use, without the many cons of using a 556 SBR (plus the fact that subsonic 223 has about as much energy as a 22 long, while the 220gr 300BLK subs have more energy after 100yds of flight than a 44mag at the muzzle).
Currently I am using an AAC SDN762 suppressor, although a GemTech G300 (full titanium, both shroud and baffles) is on the way.

With a dBmeter a foot in front of, and a foot to the side of, the muzzle, I recorded the SPL of different rounds w and wo the can...
125gr OTM no can = 159dB
125gr OTM can = 137dB
220gr sub no can = 138dB
220gr sub can = 121dB


So, you are talking levels of sound pressure akin to firing a rifle. Keep that in mind.
Thank you both, nleksan and mikeaj, can't have too much education and reality checks in these types of threads.

Sorry for the long quote, I felt like it'd be better to have the post on this page too.

You're only going to get 96dB with 16-bit/44.1Khz audio anyway, well outside the limits of human hearing. 124dB is the spec for 24-bit. The actual card as a unit can do 120dB when measured. Again, well outside the range of human hearing

I 'd rather buy a separate external amp and speakers then use a card - i used a Nad amp with 2 Cambridge speakers and the sound was amazing

Stating the obvious my friend. Of course dedicated equipment will sound better. It'll also cost several of these cards to come close to having a meaningful enough setup to negate the advantages of these cards over onboard.

It seems to be a decent unit tbh, if all you need is unbalanced output and/or headphone amplification.

EDIT: Wow, to be honest I'm quite impressed with those measurements. The 24-bit -90dBFS waveform looks REALLY tidy.
I'm surprised to see something that clean off a computer PSU. My personal experiences with any kind of PC sound cards have not been great and certainly nothing that could reflect measurements this good. Almost makes me wish I had an Essence STX biggrin.gif

If you want fancy enough speakers to enjoy the alleged benefits of an STX over onboard, you're paying a pretty penny anyway. It costs at least two of these cards to have a finished audio setup whether you had a single STX in the loop or not, it's just a DAC/headphone amp like any other.

The max one should spend is like 2K and for stereo, above that you get 5-10% at best better for 5x the price.

My recommendation is JBL LSR 305, try to find something better for similar price, or even 2x more, i dare you thumb.gif

If you want better Adam A7x for ~ 1100$ above that its just wasting money, couple that with STX and you get relatively inexpensive mid end setup, witch is MINDBLOWING for the money,
Using the Adam A7x, that would be about $3295 for 5 of them (that's if you catch them on sale - best price I've found was 659 each new)...retail would be more like $3745 and then you add $1k for a good sub, that puts you at $4745....not actually chicken feed. The JBL LSR 305 is an exceptional little monitor indeed - that would make a nice HT for a small room.

I own a D2X and one bug that's remained unfixed by the drivers is enough to put me off buying one of these.
Whenever I close a sound playing application there is a good chance (>20% of the time) that the last sound playing will get stuck on a short loop. The only way to fix this is to restart the PC.
If Asus can't fix things like this there is no way I'll be buying their new products.

Never had that problem when I was using my ST/H6 combo. However, I always used the UniXonar drivers.

I was talking for stereo setup man thumb.gif
