O2 stack with HD800 is not bad at all, but I found it lacking in dynamic contrast. Everything else was fine.

I've heard the Crack twice. The first was with the HD650 on Bottlehead's tape rig at RMAF and I didn't like it at all. The second time was a few weeks ago using HD650, DT990 and HE-500. I preferred and enjoyed the DT990. The HD650 was a distant 2nd and the HE-500 is not a good match with the Crack. I find the Crack to be a middling amp.

I've compared the HD600 and HD650 many times over the years, but always came away preferring the HD600. About 5 years ago my main rig was a Little Dot MKVI balanced with DACMagic and HD600. I preferred it over setups much more expensive and have never truly settled on a full size headphone I would own until the HD800 after going through an IEM-only phase and brief flirt with stats (O2 MK1).

Mkvi+ balanced, hegel hd20 and hd650 is absolutely amazing. I wonder how it is vs the crack.

But I am not the biggest fan of Hd800. Have heard it on expensive rigs but is a bit dull. I'm heading the audeze way after I got to compare them. I guess I like phones that is somewhat similar to Hd650

Hey 650 fans,
 
Just received my very 1st pair of Hi-Fi headphones this morning and I decided, after much deliberation, to go with the Sennheiser HD650's.  Thanks very much to this forum/website and some serious auditions I felt that the 650's best suited my music style and personal preferences.
 
As I was so happy with my purchase (and bargain!) I felt compared to share this with you. I'm based in the UK so sorry to disappoint anyone outside of Britain but for anyone looking to grab these headphones for a good price, I managed to pick these up for £268.00 from a company in Leeds.
 
The company is called Bop DJ, here is the link: http://www.bopdj.com/sound/headphones/sennheiser-hd-650.html 
 
They retail the HP's for £288.00 but for your 1st purchase with this company there is an online voucher for £20.00 off that price, plus if you order before 3pm, they will send them next delivery and that was free.  Next best price I could find was Amazon for £309, so I was very impressed with these guys.
 
I did see 2 other stores for cheaper but after a little research on here i quickly discovered they were Asian companies posing as companies based in the UK, so do beware as some folks have had grief from these companies and I personally didn't think it was worth it.
 
Hope this is useful.

Could you link me to carbon fiber wrap that you used?

Check out my bottlehead link above, second post. It is not wrap but 2 layers of 200grm real 3k carbon fibre twill fabric infused with expoy resin under vacuum and heat cured at 80 °C.
 
Thanks Parbaked you beat me to it.

Back to the club.....my third pair now.
They are really a heavenly combination with the Crack,better than the HD600 ,me thinks.

Just wait till you heard the 650 with the Graham Slee.

novo is great but srg2 or ultra-linear diamond left me wanting nothing more.

It seems this ebayer only has 10k and 250k. Would it be better to just wait around until the 100k's appear?
