only 300 mW at 60 Ohm headphone output
no replaceable op-amps
some security problem with FireWire
it isn't available in my town
Regardless, you may have to do some looking around aka: research... or even possibly order a device (which a store should be able to do for you - in most cases a down payment is usually required...). Obviously, there are other ways of getting what you want like ordering it online, whether that be right from the manufacturer, used/new on sites like ebay ... There are options anyway, so look into it...
I bought the presonus because of light weight / small (but rigid design) and mainly for live-use, so 96khz is totally fine...it's also much nicer to bring around ~ since it's not a heavy expense to replace (ie: i don't want to shuffle around my RME). I also don't need to be able to input more than 6 - 1/4 inch cables at once and the 2 front panel preamps (XLR or 1/4) have decent headroom and sound pristine/decent for the price/class of device.
This is an internet forum. I believe that such things should be used to share knowledge and information, not to engage in ideological wars, such as I see so bloody often. Pulseaudio bad, Ubuntu bad, Alsa good, hardware mixing good, etc, etc. Such a misuse of the net.
HW mixing can be advantage in some cases, but it isn't option in many cases. If I would have to buy new sound card tomorrow I would still buy sound card without HW mixing because there is no reasonable priced card with HW mixing
which provides high quality sound to my headphones, which is most important to me. Using two sound cards is unacceptable because it isn't possible to connect one headphones to two sound cards at same time.
Needless to say, this would also translate to "if you want non-crappy audio on Linux pay 200 bucks for a sound card."
Look guys, you are starting to twist this all around. I said for me that isn't some huge expense. I am not saying everyone _must_ go out and by a $300 audio interface, but if they desire certain features (and we were talking about H/W mixing, as well as me asserting earlier on that not everyone needs it, nor some of the features i would commonly use to add to that), then there are devices for $300 and under, that if chosen well (ie: researched and it's well-supported) work quite excellently under linux these days.
....arguments to be made over where money should be spent on one's computer is up to the individual to decide. For me, in both machines (Phenom II + i7) that i use daily, i don't feel the need for any upgrades, really - aside from adding the extra 8gig of RAM that i _could_ add to each machine (they each have 8gig right now) ...if i really felt that i needed 16gig of ram, which i haven't yet - maybe that will change... Both machines have decent Nvidia GFX cards (no more than 2-3yrs old), and decent sized drives... and i have other junker-boxes lying around too - so it's quite justified (for me) to make that kind of purchase. Just like in the next year, i hope to purchase an SSD/pcie hybrid card (although, that is entirely another subject :))
hd audio / onboard cards vary in H/W and driver quality(especially, in linux) and there are definitely other options, whether that be some ASUS gaming type soundcard, or to some low/mid/hi end audio interfaces that comes in a variety of shapes, designs and sizes, depending on your needs.... but in most cases, you really do get what you pay for... (and in the case of linux, there is the extra hassle of often having to know exactly what you are buying, as well.).
