SB0460 with LME49860
- hardware configuration TEST-012

I think something cool has happened, but will wait for Germanium's RMAA Detailed test result evaluation...

RMAA v6.0.5 Test Results:
Summary: http://www.esnips.com/doc/ef41dea9-0.../X-FI-MOD-046b
Detail: http://www.esnips.com/doc/a562738d-6.../X-FI-MOD-047b

I'm going to receive AD8599 and install it on my X-Fi Elite Pro Breakbox, I already installed LM4562 in the front-out and I directly plug HD595 without amp but I think the supplied current from LM4562 isn't enough for driving HD595 to its potential.
So, will AD8599 drive HD595 better than LM4562 with almost the same sound quality?

Linked tests perfectly overlap with old tests, No differences at all here. Are you sure you posted the correct graphs?? Never mind the test results exactly the same also.

Hi, do you want to change to latest official (/beta) driver to do a test in 16/44.1 and 24/96?

Quote:



The Prelude would likely have a better chance out of the 2 soundcards & would likely sound better overall even if you used a seperate amp. not sure of the voltage on the opamps on the Prelude but it is probably the same as the Elite Pro which has +/- 12 volts where as the lower cards have only +/- 5volts which could seriously limit the output of the lower card into your phones. Either way though you still may need an amp. I don't have your particular model of phones so I don't know how they would actually work. Out of the soundcards though the Prelude has the best chance is all.

Maybe later as I use Vista almost exclusively as I have fewer problems with it than XP. Especially since EAX always crashes on shutdown on XP with my dual core CPU. It never does this on Vista. Vista seems to handle 2 CPUs better than XP.

I'm just using the latest drivers from creative from time to time for my x-fi under Vista. It's stable every time.

Just now, I installed the latest beta driver 0711 , everything's okay except when I start the RMAA, the application will crash, it's strange and I have no idea to that ... and can't do testings...

Hope creative will release a new driver lately...

If I install the latest official driver on Vista I get nothing but static so sticking with the original full release driver there too.

You can go to Creative official forum to get the latest applications that can be used with all the latest drivers released. The driver and applications on the original CD are outmoded.

I have all the latest software that totally works. The ones posted on creatives site are actually inferior to the ones on the Vista CD. None of it does any good if the bare driver itself doesn't work at all.

Looked at the latest beta drivers & they seriosly recommend no more than 2GB memory & I have 4GB memory. I also have plans to go to 8GB memory in the future.

Quote:



You must have less than 2GB memory or running the 32 bit version. I have the 64 bit version & 4GB memory.

What?
- different line-out caps (not the normal conventional type)
- different op amp
- no component details, sort of a "blind test" experiment
- you sure you didn't have too much wine with your dinner?

Quote:



compared to the results you got with the previous tests with the LME49720. The graphs perfectly overlay. I went back forth several times & not even one spike changed in size or position.

Thanks again for your analysis!
Following configuration used to produce those RMAA results:
- LME49860 installed
- tantalum 22uf @ 16vdc for Line-Out coupling
- tantalum 4.7uf @ 35vdc for Line-In coupling

Tantalum vs Polarized Electrolytic (same values):
Frequency response (from 40 Hz to 15 kHz), dB +0.02, -0.16 (+0.02, -0.18)
Noise level, dB (A) -101.9 (-101.9)
Dynamic range, dB (A) 101.9 (101.9)
THD, % 0.0020 (0.0014)
THD + Noise, dB (A) -90.3 (-92.2)
IMD + Noise, % 0.0037 (0.0029)
Stereo crosstalk, dB -97.1 (-96.4)
IMD at 10 kHz, % 0.0088 (0.0058)

- fraction flatter, and fraction less crosstalk with tantalum coupling.
- fractionally worse on THDs and IMD.
- surprising result for me, since conventional thinking shuns tantalum audio coupling...

Sonically, tantalum coupling seem to deliver more bass, but a taste "muddier" and clear, well defined highs.
- overall, both are pleasing to listen to...
- if forced to choose for a design, at this point, polarized electrolytics. (still have to test direct, NP, metal film)

EDIT: Germanium's RMAA re-analysis pending, due to his, umm, low wireless mouse battery?
