So I just bought a new pair of SR325is from the US... they sound pretty good on my nuforce icon mobile but I still remember my SR125is sounding far better from a CD player's lineout hooked up to a cmoy... anyways, I'm not sure if it's the lack of synergy or whatever but I am now looking into buying an amp with better synergy... I'm not sure if the DAC in my Icon Mobile is much better than my laptop's... do I keep using this as a DAC and get a dedicated amp or should I just get a whole new DAC/Amp combo all together? my budget is about $200

That's probably because a CMoy has a warm sound.  I'm not sure what type of amp would fit you besides possibly the UHA-4 and the TTVJ Slim, but those sort of tubey sounding amps or actually the ALO Continental which is a portable tube amp would fit the Grado sound signature unless you're a treble lover then those would not be your choice as they mellow out the piercing notes of the Grado's.

The  SR125 was getting a stronger signal from the CD player, even if it is/was a portable one.  (My old Sony portable CD player makes my Etymotic ER4 sound like a 50mm closed full size headphone!)  And, yes, the CMoy would have a warmer sound as an amp.
 
Your new SR325 has a slightly V-shaped sound with upper-mids and lower-trebles emphasis, if you combine that with the Nuforce Icon (which I remember reading has a pretty cold sound), you probably have a pretty cold sounding SR325.
 
CMoys, PA2V2, or some of the Ray Samuels amps, like P4 would be warmer amps for your SR325.
