look into the Audio Technica ATH-M50. They meet all your sound requirements and are built very well.

zupa, 650s are great cans. I doubt you will be disappointed with them. Keep in mind that to hear the best out of them a decent source and amp are essential. If you find them 'boring' you can always upgrade to something brighter later. 650s have good resale value so you could get a good...

Look into an amp from Purity Audio. They should be buliding more in the next few months so you could get one then. I absolutely love the way the Caliente version sounds with 650s.

Wow that blue IS stunning! Received the 650s today and there is no doubt that combined with the Caliente they are a great duo. Now with near 35 hours on the Caliente and only 5 hour old 650s I dont think ill need to upgrade any time soon. The amp has plenty of juice, I really only had to...

so much for waiting .. might as well listen while burning in. It really turns the the M50 into a bass monster! Incredibly it at no time yet has overpowered the mids or highs and VERY punchy. Also the treble is noticibly more extended, to me at least.. with this gear. I'm really...

Got mine today and out of the box I have to say I am impressed with the build quality, light weight yet rock solid. For burn in i'm using a 'not so good source' but even so I can definitely tell that the bass has alot more control.. nice! Can't wait to hook it up to the Onkyo ... Oh and...

I have the Onkyo and to my ears it sounds very balanced. Great build quality, the only thing I don't like is the power cord is non detachable. Still the one it does come with is fine, ive had no problems. The Marantz has cd text which is a feature I wish the Onkyo had, but the Onkyo has a...

heres the links to some reviews of it, if you didnt see them. REVIEW: Purity Audio K.I.C.A.S. Caliente home headphone amp - updated with comments on regular KICAS Review Purity Audio Caliente Headphone Amplifier

I would get the Caliente.. Its designed to be warm and from reading, its seems to work well with both those cans. Plus with the CAD to $ conversion rate its a real good 'bang for the buck'. I think today is the last day to get in on the group buy. So if you decide to go that route I would...

Q40 or M50 and any amp.

also the XP-7

Purity Audio Caliente or Meier Arietta

Look at Audio Tehnica studio monitors like the M40fs or M50. They have great build quality, but can clamp a bit. The HD280 sounds good, and they are more comftorble if you have to wear them for a longer period of time.

The M50 I think would be a good choice for you. They are studio monitors with a bit extra bass response and a decent soundstage. Depending on how big your head is comfort could be an issue though. From reading the forums you might also want to check out the Q40 or RP21. I really can't...

I noticed the same thing your describing with a pair of HD485 I used to have. I always thought it was because the cord was one sided, the wire that then connects to the other driver can cause a very slight 'lag' in signal. However, the cans I use now are one sided and I dont notice a problem...
