With all the talk about what amp is best to drive the K1000, I thought I would throw out the SAC KH1000 amp. Mine did a much better job driving the K1000 than my Eddie Current ZDT or a Cavalli EHHA (as well as better than numerous 5-12 watt speaker amps), both costing 2-3x that of the SAC amp. The Cavalli was second best, and the ZDT was 3rd, but none of my little speaker amps (Qinpu A-3, Travagans Red, Nuforce Icon) could do the k1000 justice like the top 3 amps I tried. The ZDT and EHHA has just enough power at the low end, but soft on the impact, and sometimes a little muddy sounding. The ZDT was a little dark with the K1000 as well, even with my brightest tubes.
I kept the amp for so long because it can power my HE-6 too and is fantastic with Balanced HD600, plus I thought I was going to buy another K1000 someday, but my Stax SR-009 shipped to me today and the idea of another K1000 is on the back burner again. I apologize for the intrusion here, and it wont be proper for me to respond to inquiries in the forum (so I wont), but if anyone is interested in buying mine just PM me.
I totally agree with Larry. I've had my SAC KH1000amp for over a year and nothing I have compares to it for driving me K 1000's. I have taken this setup to several meets and everyone is blown away by the sound signature.
And YES, you can still purchase it 'new' as I did. Go to the site mentioned above and you'll find that they not only will build you an amp, but you can have it modified like I did to accept both XLR AND regular dynamic inputs.
They will also provide the required North American cables that you may need for this amp. I'm VERY pleased with the amp and the service provided.
