Ideally, I'd like them to be active, but have no other preferences. I'm not a fan of overwhelming bass, and I'm not prepared to invest in a DAC at this point.
If it's any baseline, I consider the sound from MDR-7506es to be closest to what I like.
Samson Media3a One are very detailed but definitely not for bass heads. Treble heads though will be very pleased-
Cerwin Vega XD3- More bass and has a certain level of detail but not as crystal ice clear as the Samson-
If you want big sound on a budget, try searching for "NXT flat speakers". You will be superised on their sound quality give the price. Here is an example.
If you want bass with "some" clarity I would go with the Cerwin Vega XD3. I prefer the clearer treble rich sound of the Samson MediaOne 3a but the bass is pretty much non-existent and this is from someone who thinks the Audio Technica ATH AD700 headphones have plenty of bass :D
