For those less familiar, it is even hungrier than the HiFi Man HE-6.
The micro iDSD will provide 8V, which is enough for 100dB peaks on the K1000, this may be enough for some, but not for others.
Incidentally, as a point of reference, the SAC Headphone Amplifier which was designed specifically for the K1000, delivers 11.5V, so ~3dB more than the micro iDSD.
The micro iDSD with the K1000...will go loud but it wont go to head-banging levels.
It really is a matter of if the micro iDSD drives the K1000s loud enough for your taste - so please try first.
Lastly, the micro iDSD won't do anything about strange looks from wearing the K1000s on-the-go...
2. Hang fire...we have another announcement today.
1. The K 1000 is an oddball - you can say it is no longer competitive with modern headphones - equally well as that ALL other headphones miss the boat - by a continent size distance ... Highly specialized earspeaker ( the term headphones does not apply, nor does it any justice ) - it can not go very loud, particularly in the bass ( the lower/louder the worse...) - therefore most at home with acoustic/vocal music - where it does not have much/any peers. It will carp out on some dubstep/electronica/etc long before people interested in these genres would start to audition it. It takes heroic speaker amps to "force" the K 1000 in this way, but IMO it is not worth it nor do I find it reasonable.
I will check the levels you posted with K 1000 - it just might be enough for a soloist/smaller acoustic group. Not planning relocating Vienna Philharmonics in some hut at 6000 m above the sea .
Regarding strange looks from wearing the K1000 on the go - not gonna happen, as I plan to use them on location recording. Besides, ICPCL ( I couldn't possibly care less ) - the Jecklin smile can not possibly prepare one for "THE Real Thing".
I am also interested in "crossfeed and 3D" capabilities for use with non K1000 headphones and IEMs. Particularly interested in driving the Havi B3 Pro (Original Version ) - one of the IEMs with the best soundstage/spatial reproduction out there - and one of the hungriest to boot. Nano iDSD drives these to about the level I hope micro will be able to drive the K1000 - I expect micro will have still lots of reserve when driving the Havi B3 Pro (Old Version)
2. Ceasefire - in anticipation of some fireworks
