Hotrodding the X-Fi: A Layman's Guide (No 56k)
Jun 15, 2008 at 4:39 PM Post #1,771 of 2,194
After scanning thru the whole thread, I decide to give my X-Fi XtremeMusic a try.
Here is my initial modding configuration, pls comment:
- C23, C50, C76, C77 - Panasonic audio cap 33uF/10V ECA1AAD330X
- C46, C72 - Rubycon ZL cap 1000uF/6.3V
- Opamp, I'll pick AD8599

However, my DVD drive is connected to it as well. Which pair of caps I should change? What value should I change?

Pls advise. Thanks and happy modding!

P.S. All components are found in Farnell.

I woudl definitively vote for the AD8599 - it has been (unlike the LM4562) apraised my many audiophiles. Just check there:
http://www.head-fi.org/forums/f6/sta...9/#post3536731

Another opamp to consideration might be a NE5532, but it is not as apraised as the AD8599 one...


The question you did not want to hear is - is your output amplifier after X-Fi even capable to let you hear the difference?

(yes, there IS a big difference after replacing the original crappy 4558 ones for the LM4562 ones, but only if you get rid of the Jamicon crap-caps and the LM4562 ones also require a burn-in time, so you hear at first a bit crazy emphasizatiuon of the details - it make my head hurt, lol ... it get settled in a 2 to 3 days to hearable output and in 2 or 3 weeks to be even compared with the 4558 - and yes, then there is still more details, but not overblown as before...

Anyways, the AD8599 is better? I might give it a try, though the samples from national are free. Ordered mine some days ago but still no shipping confirmation however

if somebody decides to open their x-mod then we'll know if it's moddable or not.

and i never got a shipping confirmation from national. one day my opamps just showed up on my doorstep, it was about 2 weeks after ordering.

Whoa that's nice. Well not really but nice you still got them. I don't know but I hope it gives no problems since I live in the Netherlands.

Well, we'll see in a week or so

you're closer in terms of shipping distance... national is based out of singapore, and that's where my opamps shipped from...

I need some advice regarding an SB0460.

My line-in is no longer working. I'm not sure what happened. I would guess that something blew. It's not clear what. I'm not set up to debug this live, as I don't have a system out of a case to probe around with.

On the SB0460. Does the line in run directly to the ADC or is there something else in between? My initial feeling is the ADC, but I'm not sure I want to pull a 28-pin SSOP for the fun of it.

Are there fuses/diodes in the path? Something probable off line (resistance, continuity, etc.)?

Thanks!

Hmm, I try to run without opamp now. I loved it very much. Even though I ordered 3 different opamp I think I don't need them anymore. It sounded wonderful without it. I even bypass the muting capacitor plus now I use decoupling capacitor, 10uF Elna bipolar with 100nF metallized polypropylene as a bypass. Its DC offset now is 12mV, if shorted its 2V, with opamp and shorted is 190mV
