Auzentech X-fi Bravura 7.1 Sneak Peek - Page 11

post #151 of 445
Damn. I knew that something bad will happen when toying up with cheap pre-mounted opamp options. Apart from OPA627BP, I've ordered a pair of OPA627AU for a rainy day and to have them handy for non critical stereo channels. OPA627AU was premounted on this type of adapter:



Now,it seems that poor soul who soldered the adapter inverted the pins for the dip socket. Those fatter pins with the ring (facing the PCB) on the picture were orientated towards the dip socket. So, in a rush to swap the opamps I didn't noticed this ... but it was too late when I noticed that I had to use more force to install them. Now, it seems that dip socket channels expanded a bit because of irregular pin size and now when I use other opamps and dip adapters they feel "loose" in the socket. I mean, they are not firmly secured in the socket channel and almost no force is required for removal. That was for my sub/center channel (I may route the sub to different channel/dip socket) ... but it seems that they are working fine for now. Not sure if connection is reliable. I'm super annoyed. I now have to buy some browndog adapters, de-solder opamps from existing adapter and solder back to browndogs.

So , people, be carefull when using the adapters and check the pin size. Otherwise, dip socket connection will be unreliable or in worst case they may not work at all.

I know what you mean. When you install the next units, bend the pins outward a bit. This way when you install them they will have a good conenction at the sides.
Make sense?

Your good enough to de-solder the units and resolder them?
I think it would be easier to just reverse the pins.

Yes, of course. I did installed it that way, at the end. Annoyed that socket is not in the top form anymore ... but hey there is nothing much I can do.

Oh yes, I'm very good with soldering and have steady hand. Inverting the pins is also an option ... but in that case dip pins will have tiny coat of solder on them. In some puristic sense another surface 2 surface contact before reaching the socket channels but hey ...
I found 4 browndogs which I inteded to use some day, hence the idea.

BTW I tried the OPA2227 for the sub channel. Very nice. For me, good opamp will not reveal the sub too much. In some sense, I dislike the idea to hear the presence of the sub. It should be transparent, rhythmic and above all nicely blended with front channels opamp sonic signature. I paired the OPA2227 with OPA627BP and quite pleased with the outcome. Thx for the OPA2227 suggestion!

No problem, they are great for bass. You are using the OPA2227 for the center/subsocket?
I built an adapter that splits them, putting a LME49710NA(HA) on the center and a OPA227 on the subwoofer. The OPA227 is the single channel version of the OPA2227.
Anyway, alteast you have the OPA2227 for bass. I have tested many opamps but I still find this one gives me the nicest bass range for subwoofer output, atleast IMO.

Ah, typo ... I''m using OPA227 (single channel one) on dual DIP8 adapter.

That is pretty much what I am using. Good stuff!
I was actually using a metal can (TO-99) LME49710HA for my center and of course the OPA227 for sub channel.

Do you use your sub just for movies or for music too (with OPA227) ?

I remember that you mentioned few times preference for TO-99 versions. I have 0 experience with metal cans. Here in the UK, I can find LME49710HA pre-installed on browndogs, but doesn't come cheap (LME49720HA is cheaper). Interestingly enough it's classified as HiFi Audio opamp. Actually, I'm currently really enjoying the OPA627 + OPA227 combo; not sure what to expect from LME49710HA. Also, trying to keep the opamp swapping craze on the bay.

I use the subwoofer for both movie and music. I do a great deal of testing, speakers, sources, electronics...etc

Usually the TO-99 are the highest grade of an opamp family. I build my own dual LME49710HA on adapters. I have also put the LME49720HA on adapters also for my personal testing.

You are right, some getting into swapping so much that they never stop and enjoy the music. I usually install the dual LME49710HA for a dual channel applications such as the front channels. So it made sense to use it for the center channel.

I'm so pissed it's not possible to install this soundcard on a notebook . Gonna move to a dorm in a few months, and i'll buy a notebook. Need a dac+headphone amp (i'll buy the akg k701), and this soundcard would have been the best choice (it's rather cheap too).

It's a great sounding card also.
post #161 of 445
Yep. I really feel envious ^^.
post #162 of 445
For the BRavura owners: can anyone confirm that the little red-marked area has "SPDIF-IN" written on it?



And if so, any idea what it is capable of doing? Does it show up in the "recording devices" on Windows 7?

Hi, I'm thinking of upgrading my XtremeMusic with this card but I have a few questions. The dedicated headphone out will be great for me (no more unplugging headphones) but I'm worried about losing the hardware DSP. I know most games now use software sound but for those that still use DirectSound3D or OpenAL how much of a downgrade will this be over a real X-FI chip? I use Alchemy and it works but I often wonder if it actually uses the hardware DSP for anything at all and if it's not just emulating eax in software, in which case I assume the result will be the same.

If I decide that I still want the hardware dsp I might get the Forte, does it also have a separate headphone adapter in windows or is it just a doubled front channel? I really need to have separate control over the two like the Bravura allows. Thanks, sorry if the questions are dumb or have been answered and I didn't notice.

PS, am I understanding correctly that with the Bravura there is no need to switch to and from audio-creation mode for ASIO/WASAPI and the driver will handle bit-perfect playback automatically?

Based on my testing this card is actually very fast for games. This card only has the entertainment mode so the drivers are quite light. There is no native ASIOdriver but WASAPI handles bitperfect in Vista/Win7.
This card still offers EAX 1,2,3,4 and openAL only done using the CPU.

Thanks, do both the Forte and the Bravura allow for separate control of speaker and headphone volume?
