I'm a regular (as in every day) user of HD650 and HFI-780 (ALO-modded) cans, and the soundstage of the HF-2 is at least as large and credible as either of those. I'm also the owner (and fan) of a pair of HD600, which, before I purchased the HD650, I used every day for a few years. I can also say that the soundstage of the HF-2 is as large and credible as that of the HD600. I was an everyday user of stock SR225 from 2002 - 2007, and am now a frequent user of a pair of ALO-modded SR225 since 2007. I did not find the stock SR225 to be as soundstage-challenged as I frequently read posted. The main difference between the SR225 soundstage and the HD600 soundstage that I heard was the placement of the listener within it. With the HD600, the listener is in the audience of a musical performance, somewhere in the 20th to 50th row. With the SR225, the listener is onstage with the performers. With the SR225, I still got a very good hearing of where the various voices were in relation to each other and to me, the listener. With orchestral recordings, and the SR225, I got the sense that I was in a large, major-city concert hall, sitting in the audience (30th row) listening to the performance of an orchestra (a listening experience that I regularly enjoy). The spatial presentation of the HF-2 is more similar to the SR225 than to the HD600, but, with the HF-2, the musical voices are spread over more space (width and depth), and the placements of the musical voices and events around the listener are more credible. For instance, when I hear a faint voice (on the recording) that sounds like it is coming from behind me, I take off the phones to check whether a family member is at my door calling for me.

I'm not expecting the same type of magic that the Mapletree is said to have with them, but I'm hoping they're still a decent pairing...

The HF-2 paired with a KICAS Caliente provides a well-more-than-decent listening experience. Compared to the pairing of the HF-2 with the Mapletree,
the only aspect of the listening using the HF-2 with the Caliente that is not on par with that from the HF-2 paired with the Mapletree is the spectral balance, which is heavier in the bottom end for my OPTIMAL enjoyment, but well within my "lots there to enjoy" level of enjoyment. I do NOT find the Caliente paired with either HD650 (often described as a "dark, bass-heavy" phone) or the HFI-780 (a phone noted for its strong and competent bass) to be too heavy toward the bass end. My take on this is that, so far (with less than 48 hours of use), the quality of the bass from the HF-2 is less transparent (with the Caliente) than that from either of the HD650 or HFI-780 (both with hundreds to thousands of hours of use). If, with more use, the bass end with the Caliente becomes more transparent and the spectral balance becomes more in line with that with the Mapletree, I'll update my impressions to include that, along with the number of hours of use at which that happened. Now, take that same pair of HF-2 (same number of hours of use) and pair it with the Mapletree - the bass is more transparent, and the balance of its presence and impact in the spectral mix is at my ear's optimal enjoyment point. Similarly, take that same pair of HF-2 and pair it with an iBasso D10 (opamp-rolled with a pair of Class-A Biased OPA350 in L/R, and a pair of EL8201's in the buffer sockets), and the spectral balance is spot-on optimal to my ears and tastes, but with a smaller (but just as competent) soundstage as with either of Mapletree or Caliente.
For a pair of phones with the capacity for subtlety and competency of expression as the HF-2 is showing itself to be, I'd expect that I won't really be hearing them as they ought to be heard until they have hundreds of hours of use on them. At under 48 hours of use, what is described above is how I hear them. If there had been any changes in the sound from the HF-2 during that period (other than the usual clarifying of their sound and increasing their effective sensitivity), I would not be posting this (it would be too early to post reliable observations). Seeing that this is my fourth Grado, and given the consistency of sound (along with consistent improvement with use), I thought that another description of their sound would be a good addition to this thread at this point.
