Just a week ago, I bought a pair of PROLine 650s after a long search for some exciting (but warm and rich) closed cans. I got them B-stock from Headroom, so presumably they've had some burn-in time. They've grown on me since I got them, but I still find them unimpressive and only a little better than my workhorse cans (M40fs).

They seem to do well in solo, acoustic-type music, but the sound turns to a bland mush when more instruments come to the party. Incidentally they sound great with Sgt. Pepper's Lonely Hearts Club Band; an album that seems to have a lot of stereo separation between instruments and vocals.

I'm only using and E-MU 0202 USB to drive them though, so my question is - what's to blame for the "boringness" (technical term

)? Is it the cans, or is my source just not giving them what they need?

Do they need an amp?

No...

Will they sound better with an amp?

Yes...

X2. The 2500 is more neutral. The 650 is fun. I like it for movies. Amps ALWAYS make a diffference. Providing your source is good. And it's signal is clean.

Thanks guys!

Are there any reasonably-priced amps I should look for that pair especially well with Ultrasones? How about tube amps like the Little dot?

I lub my PL650's but they seem to have what I would describe as flange effect. With songs that were not mastered for stereo very well the flange becomes very noticeable. I don't notice this effect when watching DVD movies, or when playing well mastered music like Astrix or Dre.

Example: When I listen to Yes - Yes (album) I hear a lot of flange.

I prefer the Ultrasone with Solid State. The 650's bass would tend to runaway. Just one man's opinion.

What's your budget??
