This is a one song comparison between the Sonic AD2k+ vs. the PCM-M10 of Futurebirds at Bowery Ballroom. Each file is 24/48 FLAC and the recording setup was as follows:

Source 1: Schoeps MK4 > KC5 > CMC-6 > E.A.A. PSP-2 (via XLR Out) > Sonic AD2k+ > Tascam DR-680

• Input Level +20 dB
• Sample Rate 48kHz
• Word Length Mode 24-bit

Source 2: Schoeps MK4 > KC5 > CMC-6 > E.A.A. PSP-2 (via stereo mini out) > PCM-M10 Line In

• Record Level Dial ~2
• Sample Rate 48kHz
• Word Length Mode 24-bit

For post-processing, nothing was done other than to invert the phase of the AD2k source and add gain so that the left-channel peaks were identical between the two sources. One important thing to note is that there was a 0.36 dB channel difference between the two recordings. I don't know if this was caused by a channel imbalance on the PSP-2 outputs, the AD2k inputs, or the PCM-M10 inputs. Nevertheless, they are as close as I could get them in Peak level and Average RMS.

Yep, sent him a PM.

I wouldn't kick either out of bed, but I give the edge to sample 1.

I place comps like this in audacity, mute one pair and then hit solo on the same pair (turn solo on/off to instantly flip back and forth). Then give a full listen through and pick out a quiet section to listen for microdetail. There seems to be something in the upper presence band on the guitar in sample 1 that I just thought was a better image. Not necessarily more prominant, but a better focus. I caught it 3 or 4 times when flipping but it wasn't consistant. The microdetail didn't tip it either way. Dunno, like I said, I wouldn't kick either out of bed, but if I were the one schlepping the gear, I'd probably skip the ad2k as I'm not getting enough difference to lug all that stuff around.

edit: listening gear: macbook > optical > usbpre2 > audeze lcd-2 rev2

Tonedeaf and I did this exactl comp with the moe acoustic set at summer camp. The acoustic set sounds killer so that's going to be a good comp as well ;)

I picked #2, and I guess its the pcm-m10

If we can get a few more listens and votes I'll go ahead and spill the beans for which source was which.

on my work computer with earbud headphones i could not hear much of a difference.  my initial reaction was that sample 2 sounded a bit "warmer" and sample 1 had a bit more "sizzle", but the more i listened the more the tracks sounded the same.   

This one would have been interesting to do ABX style with 5 of 6 sets of randomly assigned 30 second samples.

This could be accommodated. I wanted to get something up and quickly choose to do a 1 song comp, but I still have this recording and could make more comps (of other shows) anytime.

I'm torn; I don't care enough to go through with the exercise in multiple samples that were randomly labeled, but the scientist in me wants to do it well.

next time I guess. I've ABXed stuff before and it's useful if you're not sure you can make a truly honest opinion of something, but for the quick and dirty the above process is quite sufficient. Thanks for posting stuff.

Thanks to everyone that voted and provided their thoughts. The sources were:

Sample 1= AD2K+
Sample 2 = PCM-M10

I'm very proud of my ears (and/or total 50/50 luck)
