HD650 is not dark/warm enough...need your advice.

Hi guys, I bought my HD650 only a few months ago, but I realised that they are posibbly not for me since the sound is not like I thought it would be.
it is a tad bright with the mids too much farward. it is the new version ofcourse. my earmax pro is helping a little to improve the situation but it is still not warm and bassy enough for me.
in fact, I love the general sound, but only if I can get a little more bass response and lower the treble/mids a little they would be great.


what should I do? :

1. getting a whole new OPEN headphone (I am interested in a open headphone) with a dark/warm signature. I would be happy to get some advices.

2.trading my HD650 to the old version...? (but only if the difference is more than subtle)

thanks.

thanks for the advice. are you talking about the K240 MKII? i saw a pair at headroom but I don't know if that's the one you are talking about...

AKG K 240 MK II - Full Size Headphones | HeadRoom Audio

they are closed though...and i was thinking about something open.

I am using my marantz cd player as transport for cds..how can i use EQ? (it would probably be a good solution ) also, I don't want to degrade the sound quality by adding another part to the chain.

already did that...all the 3 tubes are mullard. my HD650 have a nasty plastic bright sound to them...don't know why, I don't think they should sound like that.
