Hotrodding the X-Fi: A Layman's Guide (No 56k) - Page 81

post #1201 of 2194
i don't understand what were u guys talking about in the last few pages...
less words, more pics please.

is using ERS paper really making the sound a lot warmer?
coz i find my X-Fi with LM4562+BG NX Hi-Q a bit too bright to my ears.

Lots of pics in the links provided. Pics need explanation & analysis though & that why all the words.

try posting thumbnail links or maybe direct image.

My pics too large DATA wise for my account on headfi & thumb nails themselve don't tell you much. Not sure how to do a thumbnail link.

ok... anyway...

my second question please.... is there anyway i can make my X-Fi warmer....
it's piercing my ear.
post #1206 of 2194
figures....
no answer....
post #1207 of 2194
Change your speaker cables then, or use LME49720 which is slightly warmer than LM4562

Not sure what you listening to your X-Fi with but most of these mod actually are to bring out more detail not less. I find with my listening equipment more detail & high frequence extension without sounding piercing at all. It sound smoother & sweeter but definately not warmer like you seem to want. A little bit of EQ can warm things up for you if you need as can reducing the treble reduce the piercing quality but I would really look at the rest of your playback system as my mods do not make the high frequencies piercing or harsh. Only more detailed & sweeter to the ear. Certain earphones like the UE superfi 5 pro can be piercing to the ear even with the stoc X-Fi cards

i doubt a humble z5500 will do that....
detailed, yes.... very detailed indeed...
but clearly it's way to fatiguing.

The Z5500 is exactly the type of speaker that I would expect to do that. It is a single full range driver sattilite with subwoofer set up. That would have to use a fair amount of EQ in the sattilite driver amps to get good high frequence output & the drivers themselve would likele start to "breakup" as the driver is not optomized for high frequencies.

I'm running professional biamped near field monitors with a 5 1/4" woofer & 3/4" tweeter & a very high quality subwoofer. I modified the amps in these to improve even on these qualities.

3" full range drivers cannot match this setup for warmth or detail w/sweetness.

so?
will ERS paper helps?
coz i haven't use any

So I finally got around to doing mine. The only soldering that I've ever done was to reconnect a headphone wire that was shorted (the hd580 wires are cheap as hell). That being said, the walkthroughs found here and elsewhere allowed me to competently perform the swap in less than 30min. Indeed, my sloppy removal worked in my favor as I was able to use the old solder for some of the reconnections. I havent made up my mind on the difference in sound yet. Thanks to everyone who has contributed to these guides.

ter1,

I fully understand the DAC/ADC "limit(s)" of the X-FI SB0460 vs. SB0550.
- main purpose of my "experiments," is to prove/disprove theories and design habits about capacitors, both coupling and bypass, in the audio frequency range, and potential improvements by op amp change-outs.
- to make the card "easily changeable," sockets had to be added for SOIC op amps and coupling capacitors.
- wanted to find the objective improvement limits by op amp changes only.
- objective performance improvements to the card is secondary, but will take any "sonic" improvements, if they occur.

Purpose for publicly posting results is:
- act as a sanity-check/reference.
- third-party analysis. (Germanium's excellent RMAA analysis, for example)
- provide mod data/methods for others on their mod quests. (soldering paste method vs., wire solder, for example)

Challenges I have made, "gonna kik-yer-DirectCoupled-hinder," are in jest and not serious at all.
- more to "prod" Germanium to socketing his Kung-Pow SB0550, in a "fun" way....

When all the SB0460 "experimental" fun is completed, I might find a SB0550 in my Christmas stocking and with the body of experimental data, it will be much easier to achieve top "modded" performance.

Hopefully, you and others will find some useful data/methods for your mods from my experiments.

On that note, back to swapping coupling capacitor types and testing....

EDIT: ter1: if you have practical experience coupling with metal-film vs., electrolytic, P and NP, or tantalum, I'd like to hear about it.....

Just got done with the 12uf mod. Sound slightly more full now, still retain detail though.

The long leeds on the 12uf caps did bite a little on the noise figures but not very bad. just a few small spikes in the upper mids but still reads the S/N ratio as better than 116db

metalized-film? - power bypass or coupling? (thought you are using direct-coupling, right?)

about to measure DC component on coupling caps, both Line-In (to Wolfson WM8775 ADC) and Line-Out (from Cirrus CS4382 DAC to op amp(s) differential input)

Back in a bit, with results....
