    Would an amp improve the sound quality of a SRH440?

    Hey guys, so I'm planning on getting an amp with the SRH440s. I was wondering if an amp would improve the sound quality of the 440s in any way.   Also what would be the most neutral amp to get for around $50?   Oh and I'll be listening with a Fuze.   Thanks. :)

    Amp for Shure SRH-940?

    I'm currently selecting an amp to go with my Shure SRH-940. The options that I've been considering are:   1) Digizoid ZO2.3: I like the small size of this thing, and the bass boost would be nice to use every once in a while. However, I am mostly happy with the bass amount in the SRH-940, and...

    JDS Labs C421 vs Little Dot Mark III --?

    parameters of decision:   both have similar price, so that's not the issue.   I don't like tube rolling. I need it be compatible to fit also IEM's. it needs to be as reliable as possible.   heard good praises about both, but i guess they do have different sound/flavor.    ...

    [Impression] JDS Labs C421 (OPA2227 vs. AD8620) featuring cmoyBB, O2, T5 and UHA-4.

    I have to admit that I took immediate interest when JDS Labs announced their C421 project. Not only because their cmoyBB has impressed me before, but the fact that they are offering C421 alongside with the much acclaimed NwAvGuy’s open source Objective 2 (O2) amp (*End Note 1) is a great sign...

    Fiio E7 vs iBasso T5 vs More

    I'm looking for an amp for my DT990 Pro 250ohms. As long as it's 200 or under, maybe a tad more, and I'd prefer portable unless there's something non portable that's great for the price. I'm mostly looking for an AMP/DAC combo so it's all in one package and I don't have to buy anything else. So...
