Is it dual or single?

Wow! At http://www.mouser.com, I'm surprised to see that their price of a MUSES02 is currently only USD $46.25, purchasing fewer than 10 at a time.
http://www.mouser.com/search/ProductDetail.aspx?R=0virtualkey0virtualkeyMUSES02
The prices have come way down!
In November of 2013, they were on backorder at all of the reputable dealers in the U.S. I waited three months until mouser.com had them back in stock - when I then paid $75 each, plus tax and shipping.
12 Nov 2013 - They were not available at any reputable U.S. dealers.
12 Jan 2014 - I was still waiting, rather than taking a chance on counterfeits from an eBay vendor.
14 Feb 2014 - I placed an order with Mouser, buying two Muses02 for $166.87, including tax and shipping.
Supply and demand - I guess since writing my lackluster reviews of the Muses02, the word is out and they are now plentiful.

V5I-D?
D stands for Dual, S for Single
To the current original SS V5 OPAs

But SS V5I are from Burson too

I think the V5 (without I) is the follower of V5I

I've checked their website and the v5i is much cheaper, at $39 for a dual unit only. Perhaps it's a special version of the v5 with something cut to reduce the price?

The new V5i is an IC based version of the v5. It is not at the level of the v5, which is discrete. Hence the lower price. I was going to try and compare them with the v5, which I use, and was there was no reason to as the v5 is superior.

Yay! I'm hoping you can justify my comments, but feel free to vilify me, instead! LOL
It's so hard to be objective with this subjective hobby.
I have the Lycan, whose purpose was to roll opamps, so I have to.

No! You should read the comments on Bursons web-pages

Quote of V5I description:
V5 is a full discrete, V5I is a hybrid (using IC and discrete elements) audio amp!

i have more observations to share :
encouraged by this thread, and because no-one seems to have recorded the swaps per my google-fu, i rolled the liberated opa627 and then their forebears in the buffer socket, (LM)4562NA, into the i/v sockets that have a default JRC 2114D's
spec sheets show that candidates both have much faster slew rates (whatever that tells me, but i wanted to hear what it meant), with the 627 per their spec pdf rated at a 55V/µs (typ) and GBP of 16; the (LM)4562NA is also "very quick with a slew rate of +/- 20V/µs (typ) and a GBP of 55Mhz", or so i am told here :
http://www.guru3d.com/articles-pages/asus-xonar-essence-st-deluxe-review,9.html
it took two songs with the opa627 to shake my head
the harshness that i wasn't missing at all after it had been banished by the xonar and v5i had snuck back - it sounded not entirely unlike the dac in the nad d3020, but not quite as grating as my now receding memory of it could recall
the bass was more prominent, but like i said, after two songs, my eardrums felt "itchy" - as a medical person i know that's not possible, but having spent the last > 4 days listening to the new arrangement of components at some rather impressive volume, my ears neither rang post session, nor felt like they needed a rest
two songs with the opa627's in the i/v, and the v5i in the buffer and i didn't want to listen to any more
ah well... onto the 4652na's
this is a bit more difficult to judge; i am well aware that after > 50 hours of rather concentrated (and concentrating) listening i have undoubtedly become accustomed to the sound of the default i/v jrc2114d's with the burson v5i, and i really enjoy the synergy
the 4652 in the i/v are still good, but different, in a way that i find less appealing
the sound stage is much less distinct in placement, but overall the detail is good, albeit biased in a different way
the brass is less "sharp" and somewhat more laid back in the mix, the whole ambience is perhaps warmer but not as precise
i did note that the resonance on the infectious guitar break in kotoya's "vami duwe" had some harmonic edge to it that was spectacular, but whilst that's great, i can't be content trading the whole reproduction for a few notes on one instrument
if you like SS3602 (zilch0mod), i suspect their signature would be closer to that albeit not the clarity - headphones seem to demand a different "sound" to a 2.1 system sporting a 10" bass driver
i could only last 3 songs before i was keen to re-test the jrc2114 back in the card, and i immediately liked the result, but again, i am damned for having burnt this sound into my brain as the new "normal" in my living room
the positive discovery from my little blitz is that i am not missing anything from the parts i have available to test... i've already lucked out on the best combo for my tastes on the first roll
cheers !

4562 is nice, but needs extra PSU bypassing, usually, otherwise it can sound diffuse and rather unnatural or somehow unappealing.
LME49860 is the awesome one and my favorite National chip. One of my all-time favorite opamps, too.

I found 4562 brittle/analytic and I only like it mixed with tubes.

Now I'm pushing the DT880 600-Ohm with balanced output from the PB2 (with both sides of the two Sparkos Labs SS3602 Duals). It's almost an injustice to call the DT880 600 a poor man's HD800. It sounds so much better with twice the power from the PB2.

Here's a big question: Can you name all the (somewhat) famous headphone amps that use opamp? So far I've know the cmoyBB, Little Dot I+, some soundcards (most famous of which is perhaps the ASUS Xonar) and the xDuoo xd05.
