Both the STX and ST have the DDL enocder for the digital output. Not too many people use it though as it is a waste of the analog muscle. THhse eoncoders are common on cards that use those chipsets.
Converting TureHD to plain DTS?
Why would you want to take a lossless soundtrack such as a TrueHD track and convert it to DTS using a lossy encoder?
Both of the encoders are lossy, you should read up on them.

Are you using this card or considering it?

Ah, I think most cards would "glitch up" if you tried changing the sample rate while playing a track. Why would you do this? I mean aside from trying to get the card to freeze?

I love new toys ^^

discrete op-amps are really amazing to drive headphones, Kingwa is really the king of "WOW"

leeperry if you have some time can you test using OPA2132P in the Claro Halo?

(4 x 2132 and 2x2132+2xdefaults[4580])

So ... you are not using the amplified headphone out? Why?

BTW, some photos I took of the huge caps(noise filtering from the PCI bus I guess?):

same brand as you can find in Corsair PSU's I think? so big

and the top quality RCA outputs:

well, this soundcard runs the same DAC as the HD2, and both op-amps are used LPF for both polarities from the DAC...I know how OPA2132P sounds there, it's nice! but it can't touch LT1364 if you only use IC's...or LT1213(my current favorite, it's like a LM4562NA on steroids...it does everything the same, just better!) if you run 2*Earth as final buffers IMHO.

JRC4580 is a good guy too but well, Earth crushes it...I didn't want to try the stock 4580 or try anything else, because I wanted to have a good first impression going from the HD2(running the same op-amps)

well, I've never really liked that TI $2 chip, the friend who lent me the STX cable also doesn't like it..but he has a RSA Hornet amp, that costs like $400 or so.

you should really try two Earth on your card, these are the same as the old Burson...and they sound most spectacular! it's a night and day w/ OPA2132P, and this chip is already very nice to listen to.

Earth turns any equipment into a top notch audiophile grade PRAT machine...the new Burson is prolly even better, but it's too damn pricey and it requires a cap and some soldering....ah, deal breaker!

anyway, the drivers don't require a fixed sample rate for the analog output(unlike the Xonar cards) and KS works perfectly fine on XP SP3....and the background is as black as can get

This is the page were i can buy it right? Cost? I need some good link to LT parts, because samples never comes ....

yup, there's a link for shipping costs on that page

Earth gives a tubey/euphonic sound, so you might as well try parts from TI to feed it like the OPA2107AP...I'll try it some of these days, this combination should be nice.

I'm currently running the OPA2107AP+Earth, they work very nicely together...one brings a clean & clear DAC post-filtering, and the other a tubey audiophile output buffer

I just found out from HT Omega that this card is just like the Essence cards in that it can't provide bit-matched output for all sample rates. Both 88.2 and 176.4 are resampled.

Perfect! TI always send me samples!!! How do you compare 2107AP+EARTH vs LT1213+EARTH ?

Can you explain me the connections in red?

The connection in red are for grounding you can just connect them to a PCI screw or other grounding point. Helps improve the sound quality.

Quote:



the 2 discrete op-amps have a ground wire, I've used a nut, a bolt and an extra wire...then added electrician tape around it, and plugged the extra wire to the top screw of the card's backplate.

you can also try to leave it ungrounded, but Earth sounds better this way.

yep, OPA2107AP is good stuff, it matches nicely w/ the Earth tubey sound

I'm not exactly sure how it sounds against the LT1213 as I've currently put back my HD2(this Claro Halo is not mine), but all we aim at is feeding the Earth w/ a clean/clear/natural/balanced DAC output...OPA2107AP does the job beautifully(you could also try the stock JRC4580)

Quote:



yup, the VIA Envy24 drivers also don't support it...the ESI EWDM drivers do support it, though(they also have an "auto" sample rate option that forbids SRC, like on the VIA chips).



but honestly, I only have one DVD-A from Seal that's 88.2kHz, so I can live w/ that

Quote:



OPA2107 would be 95% as good as OPA827(that I've also tried, and this one sure is nice...but it needs adapters, and I tried it on browndog's that seem rather low quality, especially in an EMI hostile environment like a PC case): OPA827, is it sonically comparable to OPA627? - diyAudio

if you have soldering skills(or know someone who does), try the 827 on these high quality adapters: SOIC to DIP 8-pin Convert PCB Adapter - eBay

and don't let haloxt put them backward on your card
