I don't exactly remember, But it rings a bell or two,
I think Colorfly C3 would be a decent pairing for SM3 V2, but I cannot try atm because my unit is on loan, I'm using Rocco BA and Colorfly CK4+ / C&C BH rig, (mostly the rig) They sound decent, rather full, upfront, slightly thick, using a silver plated interconnect on my rig helps brighten them a touch. I don't have a problem with the mids sounding dark or veiled, I find them pretty spot on for their intended signature with a quick adjustment period. They have a certain tone to the mids which I can see appeals to SM3 lovers.
I kept reading they lack clarity, but I think there's enough there, my rig certainly push that through. I find the bass punchy / extents deep for BA, I need to put them through my CK4 / C&C BH to really milk the most from them and find it truly satisfying, I don't think a Clip+ will cut the mustard here. I am not overly impressed with their separation, if you have heard RDB+ V1 one can understand where I'm coming from. Detail wise, sure they're decent, you won't hear the tiniest of samples, but they weren't really focused with that in mind. I do enjoy that bass punch and tone they display in the mid range. Taylor Swift sounds really nice.
I believe it's just a general rule, as you go up to higher range IEM, your source should be upgraded otherwise you're merely limiting potential. Like putting a rev limiter on a car, or only turning a tap on half way. It's just... they ear rape me, (and I hate using that word), the fit and cable is just ***$#@$# to deal with. I put them in and feel like I'm being anal / ear probed. It makes me laugh how awkward the fit is for me. You insert these dongle double flange tips deeply into your ear which fold, bend, itch your ears, then mess around pulling on your ears wiggling them in every which way so they seal, then once that's done the cable chokes me pulling on the hoops. Combine all that together it kind of ruins the moment of listening. Comfort is important.
I need to change the cable for starters. It feels like I'm strapping myself into a torture device, and this is coming from someone who got a perfect fit straight up with TF10. There have been moments I've said to myself "nah I can't do this" having to unplug myself, retracting the rape tips from my ears. Comply won't seal for me (large ears) so it's out of the question. This is a first major fit problem for me personally.
I'm with you on upgrading the source. I am currently using my Rocoo P as my main source and an iPod Nano 6th-RSA P51 Mustang Rig. I tried the 4th Gen ipod touch and sold it and then got the the 5th Gen iPod Touch and sold it after 3 days, got a 7th Gen Nano this morning and I am also selling it tonight. All these ipods didnt fair well with me as far as SQ is concerned...Why try so many different iPods then? The UI form factor I think is unparalleled and the user experience is just excellent. I love everything about iPods except the sound...ironically. I don't know why but I am finicky with sources, the Clip+ didn't last 5 days with me as we'll, and I think I may have gotten a defective unit...
To me, the Rocoo P and my Shuffle 1st Gen are the best sounding, followed by the Nano-Mustang combo. The C3 is next for me and I will get the C&C BH amp as recommended by Techno Kid as well. We will see
