Not in terms of power, I mean sound quality.

The O2 is a transparent amplifier so power is all that really matters. It has more than enough.

Alright I was wondering because I hear that the Fiio E12A was very close to the O2 in terms of transparency and SQ, and the Cayin C5 is equivalent to the E12A but with substantially more power and better soundstage.

I think the amp requirements for these headphones is way overstated. I don't have a 650 but from the specs the sensitivity is over 100 db/mW. I have a 600 and the sensitivity is 97 db/mW so it's even less sensitive than the 650. Even still, I can plug these into my laptop and at Windows volume 20% it's more than loud enough.

 

Currently using a E10K. I'd be more than happy to get an O2 or Magni if someone can prove that it improves the sound but I don't understand how. I think it's placebo...

Loud and sounding correct under tight control are not the same thing.  A 300 ohm headphone needs to have ultra high sensitivity, this is similar to a 92db headphone at 50 ohms.

The HD650 scales very well, most of us here I suspect have at some point thought the same thing.

 

Volume isn't everything.  Try the O2 or Bottlehead Crack, Project Ember, Torpedo etc and see for yourself, keep a open mind and you may well be in for a pleasant surprise at what the HD650's can deliver.

Since they're your ears, you're the only one who can really prove or disprove it in the end. I got my Magni before I had the HD650, when I was trying to power my 600-ohm Beyer DT770s. Having an amp really did help fill in the bass. With the HD650, I don't find the change as significant. Comparing my setup vs straight out of my iMac, the most notable difference is a smoother treble, which could be the amp or the Wyrd/Modi.

 

Edit: I should say there can be other slight differences if I listen critically, but I try not to. I listen to enjoy, not critque, and the thing I notice easily and enjoy after my quick test just now is the smoother treble.

I think it's unlikely that those portable amps are as transparent as the O2 but whether the difference is audible I have no idea. I also own the Fiio E18 and whilst it does technically have enough power for the 650's I have to say the sound is quite a bit different. The E18 sounds more exciting I suppose but it's not so good when it comes to subtle details like room acoustics.

 

To be perfectly honest though there's not a lot in it either way. If you think you might want to use the amp in a portable context as well then I'd probably go for the E12 or Cayin. If it's just going to be sitting on a desk or shelve I'd go with the O2 or Schiit or another of the many desktop options. Get used to the headphones first though because otherwise you'll be chasing your tail forever.

Well it's been said that the Fiio E18 is a level lower in terms of SQ quality compared to the regular E12. Besides that I mostly play music when laying in my bed, and I carry the amp over to my PS3 for gaming. I dont have a computer at the moment.

As a very quick question: does going balanced mean needing both a balanced DAC and a balanced amp?

 

I'll probably ask more once I get pass the "I now own a BHC" mark.

I have Both the CRACK and The SEX amp.I will skip the CRACK and get the SEX instead for the purpose of going Balanced without needing a balanced input.

Silly question, but what's the point of having balanced output on a single ended input? Doesn't that negate the "balanced" part?

The SEX does not have a balanced input it only takes SE input but you can switch it to output  Balanced/SE mode.
