For most guitar players makes sense to go back to Cabs as most of us have some lying around, it feels better due to the pushed air from the coils, and the vibration transmited in the room from the heavy mass cabinet. But thats what you lose, soundwise is not too different once you get your eq right. I added a Subwoofer to the 2 Headrush FRFR108 set, and the sound is stupidly big and powerful, it reminds me to the time I used a oversized Mesa 4x12 with a friend trough a matrix amp, it was great with merged profiles, but to get the pushing air, the volume had to go beyond my comfortable listening level for a room (Live is another story I guess). So far, my setup gives me the best of both worlds, not the amount of air for a pushed 4x12, but enough to feel the power on my feet, at a lower more comfortable volume.
That of course is MY ideal setup, as I am not willing to deal with heavyweight cabs and high volume to get a great tone. I have a 2x12 celestion cab which would be a middle ground, but I feel Celestions are not great with all the profiles, I will surely try the Kone, as this would be a awesome proposal to solve my problem of not having a considerable amount of Cabs to mix and match. I guess some people like to match the profile to the CAB they have, but for me is the other way around. So waiting for the kone eagerly.
Whatever you choose, its great to hear the flame is still going strong, I particularly enjoy sharing these kind of experiences, so tempts me to go back and try new/old things, I have a particularly strong hearing (at my age can hear up to 18kHz which is not common) so I bet my liking will evolve with the years.
