Don't think I can the aforementioned ones can be easily available here

.Even PPAv2 and SOHA also good enough for HD650?Then my LD2+ should be doing a good enough job here

The LD2+ isn't specifically designed around a headphone load and generally all they do is stick a resistor there to give the normal output a voltage drop high enough not to fry your poor cans.
Maxxed out PPAs with Black Gates, Elnas, RN55Ds, RN60Ds, Silver hookups, WBT RCA connectors, Hand matched FC JFET pairs and OPA637s are a fine way to go, although the BOM will cost you an arm leg and an ass, and if you add in a discreet power supply ala STEPS, with all the expensive Nichicons, Vishay chokes, LDOs and Soft Recovery Diodes. You can be sure that your cost will top out past insane (1.2k minimum per unit maxed out not inclusive of PSU, PSU, add another 500 tops)
If you're even more hardcore, go for a balanced setup. Twice the fun at twice the price. One amp and one PSU for each channel. Might as well throw in a ladder stepped attenuator, mylar foil shielding, copper wire braids and Tyco IEM con-filters while your at it

Well, as per the above, my suggestion is to go DIY, you tailor the sound to your liking, your ability to pay, your space and your needs. I'm sure there are tons of audiogeeks out there who are willing to build something to your specifications given the funds. Be it an M3, PPAv2, PRII, PIMETA, Beta22, Dynalo and Such.
Although, people seem to lurve the Dynalo and it's PSU for HD650s.
Anyways, i'm building a Maxed out PIMETA for backpack use

, with dual OPA637s, an OPA627 in the ground, Quad Buffers per channel, Alps RK027 as a pot, Hand Matched JFETs, Linkwitz Crossfeed, Philips Soft Recovery Diodes, WIMA MKT-2Ps, Maxed out TREAD Regulator, and i'm stuck between Silmics and some old Philips caps which i bought for no apparent reason. Wanna buy lol?
