I said the "mid and upper bass" is elevated, not the mids. The mids are well set back from the bass - which sometimes gives depth, but more often is false and attention grabbing.
Try the HD600 on the bottlehead crack - it mashes my Rag 1 with the 600 (including never before heard 20-40 Hz bass). I like the 600 as a reference from 100-2.5k, but I listen to it very seldom. The only Focal I like is the Clear - but its a bit on the ascetic side for me, rather listen to the HE-500. I had a shot at a Clear NIB a month ago for $750 and I passed. More interested in the HFM HE6se for $899 new (out of stock at Adorama).
Last week or so I'm playing with Alara for $339.15. Warm, good bass, but congested sound stage stock - until I physically opened it up to being about 60% open (it was 20% open - see the Alara thread). Better then the MD 4XX, HFM 400i, HE5se, HE5LE, Aeons and Sundara. More enjoyable than the HD600. More dynamic than the HEX v2, but not quite as coherent. Lacking some depth, and treble detail, and substance vs HE500 - but its only got 55 hours on it, and no XLR cable yet.
