Is there any big difference? They've got pretty much the same specs,
but the Delta has a breakout box with 1/4" inputs (and nothing else on
the card), while the 2496 has stuff coming right out of the card.

Bottom line, is the quality going to be the same?

IME the Delta 66 is you say very comparable in some ways to the AP 2496.
For example, they were both based on AKM converters and VIA's Envy24
chipset. Despite the connectors on the Delta 66 breakout box, both are
electronically unbalanced. If memory serves, the Delta 66 is designed for
standard audio production signal voltages in and out, while the AP 2496 is
more oriented towards consumer signal levels which are 6-10 dB lower. I
don't know if this is due to the use of different converters or the lower
signal levels, but IME the Delta 66 is the quieter card.

So there is a difference. They're about the same price, and I should
have enough money for them soon.
I was actually going to the get Delta 44 - which is cheaper. Seems
like it should be the same hardware, though.

If I've got 1/4 jacks coming out a mixer, that should be +4dB, right?
Also, would I be able to plug a guitar directly into the Delta
breakout box?

I think that pretty much depends on your mixer and the outputs you
choose...check your specs.

I wouldn't count on anything being "the same" unless it has
the same model number, and even then I wouldn't be too sure.

The Delta is analog I/O only, the 2496 has one analog pair
and one digital pair of inputs and outputs.

The connectors are different, and, although not specified,
as Arny suggests, I would speculate that the nominal input
and output levels are different.

Depends on the mixer. Look in your manual. The Delta
accommodates +4 and -10 analog I/O.

Also, would I be able to plug a guitar directly into the Delta
breakout box?

Sure, but you probably wouldn't be very impressed with the
sound. Those aren't designed to be instrument inputs and
you'd probably find the record level to be low and the sound
to be pretty dull. But you'd get something out of it. The
Audiophile is probably just as incompatible.

According to the M-Audio web site, the Delta is $100 more
than the Audiophile. If you've found them both at the same
price, you're probably looking at somebody's closeout.
Nothing wrong with that as long as it's legitimate. Since
you're planning on using it with a mixer, unless you have a
need for digital I/O, I'd go for the Delta if you can afford
it.

Well that's nice. Don't know where the manual is, but it's a Behringer
XENYX 802 - I'd be using it just for pre-amps (and possibly some EQ)

Ah. Thought that might be the case. I've done it before with a mixer
(plugging into a non-preamped input) and the sound is plenty good, but
it has to be cranked to max. The problem goes away if I use a pedal,
since that's sort of like a pre-amp. Is there a transformer (or
something else) that will raise the input to an acceptable level,
without being a full-blown preamp?

It was Guitar Center. Both were about $150. And I actually won't have
digital I/O... so the AP 2496 is out.

the AP 2496 might be the better tool for interfacing with the RCA
input/output jacks on some consoles.

Note that the maximum input level is 6 dB below the maximum

So, if I've got this right... When my mixer shows -6dB (it's a 4-LED
scale - too tiny for me, really), the Delta will effectively be seeing
0dB?
I seem to remember seeing that with 24-bit converters, it's best to
have around 12dB headroom, because you don't have to worry about
"hiss" or the quality of 16-bit audio. I'd love to take advantage of
that, because even with my digital stuff, I'm in the habit of asking
people (ok, my guitarist) to play "as loud as you can" so that I know
it will never clip, but be as high as possible (the recorder is CD
quality).

The metering on your console is probably average-reading, the and metering
on the Delta is peak-reading, so they won't agree anyway.

Just watch the digital levels and everything will be fine.

Your worries come when the console clips _before_ the converters.

Even with 16-bit converters, 12 dB of headroom is not so bad. At least
6 dB would be reasonable. (And we're talking about peak levels here).

I wouldn't make a guess. I'd make a measurement. But if your
mixer looks like the one in the picture of the web site, you
don't have a -6 LED, but you have a +6 LED. If the 0 LED is
really +4 dBu out, then when the +6 LED lights, the record
level from the Delta will be -4 dBFS. I would consider the
+6 LED flashing occasionally to be as hot as you should get
giving the metering on that mixer. But only if the meter
calibration follows the "0=+4" convention.

"Effectively" really isn't the right way to look at it.

have around 12dB headroom, because you don't have to worry about
"hiss" or the quality of 16-bit audio.

I wouldn't attach those numbers to it, but it's pretty well
understood that you can be more conservative with record
level with 24-bit recording because you still have plenty of
resolution when your peaks don't go above -10 dBFS. But if
you record this way, you WILL worry that your levels are too
low because
(a) the squiggles on the waveform display won't be very wide and
(b) when you play back the recording through something with
a meter, the meter won't go up very far.

You can fix that in post-production but it WILL bother you.
You'll want to know why your levels "aren't hot enough."

even with my digital stuff, I'm in the habit of asking
people (ok, my guitarist) to play "as loud as you can" so that I know
it will never clip, but be as high as possible (the recorder is CD
quality).

It's a good idea to get them to play or sing as loud as they
can so you can check levels. Just don't set the level so
that it just barely doesn't go to full scale, set it 6-10 dB
lower. Or if you're listening to "normal" volume playing,
set it so that the peaks are between -20 and -16. That's
looking at a digital meter, not the LEDs on the mixer.

The Delta 66 is identical to the Delta 66 except for the SP/DIF I/O on the
Delta 66. If memory serves, they are built on the same board, but the Delta
44 board is unpopulated in the relevant areas.
