I'd like to use the two spdif channels on my Delta 1010 in conjuction
with my RNP and an outboard A/D to get two really sweet sounding
channels for vocals, guitar, piano, etc. The other 8 channels I'd run
through my 1604vlz because I'd probably only need them for drum tracks.

I'd also like to process audio via outboard gear such as an RNC, so it
would be nice to have a D/A option that's better the ones on my 1010,
but it's not necessary. I'm mainly concerned about getting one really
great sounding stereo channel.

So, what piece of gear would you recommend for this purpose in the
$500-$600 range? I'm totally cool with used gear, I'd actually prefer
it....any thoughts on the M-audio Flying Cow? It has D/A also, but does
it sound "good"? Thanks!

Not really, and the implementation doesn't get the full potential of the
converter chip anyway.



virtually all 24/96 capable chip-based ADC's sound the same

Not really.



Beyond that you get
into discrete componentry. You might find a Lucid or Mytek 24/96 ADC used
for $500, they retail around $750.

Both Lucid and Mytek use chips--for both conversion and their analog
stages. The design choices made with those chips can make a world of
difference in the resulting quality.




If you need the extra two inputs you
should get a dual preamp with built-in ADC, it's the only way to get an ADC
of the caliber in the D1010 at a reasonable price.

Unfortunately, none of the preamps in the affordable preamp/converter
setups compares to the RNP.

I'd be thinking used 96k from some company that recently shipped a 192k
box...

discussed. :-)

Disclaimer - I have an Apogee Rosetta AD 24/96 for sale above your
price range. I remember hearing a BIG difference from my Creamware
Pulsar convertors when I got it. It's a great unit if you can pop for
it. But as mentioned, the Mytek and Lucid units are well regarded. And,
yes, the RNP is terrific but better mics (what are you using now?) and
or/pres may improve your sound more. I've never heard anyone rave about
a flying cow.

Basically I'd like to be able to get 2 more analog inputs out of my
1010. I am considering an Edirol UA-5 for a portable recording setup, so
maybe I'll just use that for two more channels.

Not. More than half the result is to do with the analog circuitry
feeding the convertors.

A simple mod will make the UA-5 function as a standalone converter.

Really? Then I'm amazed that nobody's mimmicked the design since it can't
be so expensive to build.


The finer points of good design aren't all that easy to copy. Low noise
preamp and converter circuits (especially in a mixed-signal environment)
are particularly sensitive to power supply isolation, grounding, and
circuit layout.

Agreed, but for under $400 you can find something with ADC to match the
D1010 and better preamps than the 1604.


I thought he already had an RNP?

Just for grins I tested that RS 15-1242 A/D that someone
recommended here a couple of weeks ago:

Frequency response (from 40 Hz to 15 kHz), dB: +0.41, -1.70
Noise level, dB (A): -91.8
Dynamic range, dB (A): 86.0
THD @- 3 dB FS , %: 0.026
IMD (18 & 20 KHz) @ -12 dB, %: 68.890
Stereo crosstalk, dB: -75.8
IMD at 10 kHz, %: 0.024

As you can see, IM was problematical.

The numbers shown were for the left channel, while the right
channel THD measured about 100 times worse (clipping).

------------------------------------------------------------

Tests were run using a M-Audio 24/192 PCI interface as the
measurement device. Here are its RMAA 5.4 measurement
results @ 24/44:

Frequency response (from 40 Hz to 15 kHz), dB: +0.05, -0.05
From 20 Hz to 20 kHz, dB-0.10, +0.05

Noise level, dB (A): -98.4
RMS power, dB: -96.1 -96.0 (unweighted)
Peak level, dB FS: -86.2 -86.2 (unweighted)

Dynamic range, dB (A): 101.3
Dynamic range, dB:+99.9+99.7 (unweighted)

THD, %:0.0004

IMD (18 & 20 KHz) , %:0.0027

Stereo crosstalk, dB:-110.4

IMD at 5,10, 15 kHz, %:0.0029

Performance is about the same at 96 KHz & 192, only extended
FR (-0.2 dB @ 42 KHz @ 96KHz), natch.

Converters are AKM 4358

I/O buffers are 5532 (lots, since it appears to be nicely
electronically balanced, in and out).
