Ok I finally able to test my VERZA with most of my gear and here are the foundings:
Puddle of Mudd "Blurry"
iPod Touch 5th Gen
iTunes with AudioQuest DragonFly from my Alienware M18x R1
V-MODA M-100 with 1 button and BoomMicPro cables
AudioQuest DragonFly 20%
VAMP 30-40% (can't be sure since there are no marks)
VERZA 30%, 100% in computer in USB-DAC mode
All iPhone, iPod, VAMP, and VERZA EQ and 3D mode OFF.
Test 1 - With and with out the 30 pin adapter for the iPod Touch 5th Gen: I can safely say that to the best of my ability that I detected no difference between the two given that the 30 pin adapter has a Wolfson DAC inside. I can assume it is properly bypassed in this case.
Test 2 - iPhone 4S vs. iPod Touch 5th Gen with VERZA: I can also detected no difference in this case
Test 3 - VAMP vs. VERZA: as mentioned before the VERZA was tuned for the M-100 and it shows, and you can definitely tell that the VERZA gives off a much stronger base and mids but the high end suffers. This is the one point I don't like about the VERZA as I think it is too far away from neutral even with EQ off. It by no means sounded bad, but if you really care about neutral sounding high notes you might not like the VERZA.
Test 4 - DragonFly vs. VERZA in USB-DAC mode: this is where the VERZA get interesting, as the VERZA is even more bassy sounding than in iAMP mode. Personally I considered the DragonFly gives off a very good neutral sound, so the difference here is even more striking. This test could be an indication that USB-DAC mode users for computers or Android devices will notice more bass and mids compare to their iDevices counterpart given the same songs and settings.
Test 5 - Zune HD: failed as I forgot that I need to get an USB to micro USB adapter for it to be used in USB-DAC mode, so stand by for this one.
Future plan: I have a pair of Sleek-Audio SA7 coming so I will have to test that along with all my other IEMs. As a quick note I did pair my VERZA with the Ferrari T350 and does make it sound better and more lively. Since now I have the VERZA, I can finally send V-MODA another RMA request to have my VAMP updated again, and hopefully fix some of the issue I still have with it. I hope this help to some of you that are on the fence about the VERZA, and my bottom line for you is that the VERZA is a great device as it does so much and compatible with almost everything. However, sound wise the VERZA is really not for everyone even with the default setup of it pairing with the M-100, so take advantage of the 60 days trial period that V-MODA offers and judge for yourself. I hope some of you here will able to test the VERZA plus Samsung GS3 with Metallo case combo in the future. Hope this helps.
