I was under the impression that the he6 was already discontinued. I wish they had a successor announced prior to discontinuing the he6 however...
That's what I was told by my retailer. Appears to have been dropped from the lists of other major Australian retailers too.
Edit: BTW, I now have the Xindak PA-M class A 25W power amp in my system and hooked up to the HE-6.
The external construction of this amp is ridiculous for the price - it looks and feels like it should cost (at least) 3x the price.
Had an issue with the balanced input - haven't had time to sort out if this is a cable or amp issue at this stage.
Using the unbalanced inputs I also had an issue with my normal unsheilded interconnects - I got a slight buzz in one of the channels - these cables are dead quiet with my Khartago amp. Substituting a Furutech shielded cable eliminated this. This is a bit annoying to me, but won't concern most people as almost all 'normal' cables are shielded.
It's probably unfair to critique this amp with only about 12hrs use, but (at the moment) I would say it lacks the neutrality, inner detailing and greater spaciousness of the Khartago.
The Xindak also has a darker tonality than the Khartago, which may be appealing to some but it does leave more a thumbprint on the music than the more neutral Khartago - curtailing some of the freshness and individuality of music. It's worth noting that my Odyssey Khartago has most of the optional factory upgrades which make it about twice the price of the Xindak.
Comparisons to the Khartago aside, I think the Xindak sounds quite good. I like it better than my memory of the Violectric V281 which offers similar power into 50 ohms but is considerably more expensive. In material terms the Xindak would appear to offer far better value than the Violectric, though of course its just a power amp.
Another thing of interest - the Xindak has output power meters which are calibrated (?) to show W/8ohms. So far, even at loud levels, I haven't seen these meters go over 3.75W - which equates to about 0.6W/50ohms. Hmmm.
