My K1000 (#1378 bess-heavy) sound fantastic off the Eddie Current ZDT - the best I have heard them sound to date. I was all ready to sell the K1000 if this amp didn't improve their sound to what I expected (and bring the K1000 closer to the level of my HD800), but it did it in spades.
The missing sparkle in the K1000 that I loved with Naamanf's B22 has now appeared, the vocals are more vivid and rich, macro and micro detail is noticeably improved, soundstage is more solid, and bass is as strong as before but now much better controlled. Plus they play as loud as I would like via the 4-pin XLR jack, when fed via RCA out of my PS Audio Digital Link III. So there is no advantage to using the stock K1000 speaker-terminal pigtail with them, and instead I can use ZDT speaker out for my Stax transformers (will try later this weekend). The PS Audio XLR out > Jensen transformers XLR-to-RCA converter > ZDT has slightly less volume at a given volume knob position, but the amp still has enough gain to drive them well.
None of my small 5-12 watt speaker amps can drive the K1000 as well as the ZDT (Travagans Red, Nuforce Icon, and Qinpu A-3), nor can my Single Power Square Wave XL balanced amp. The Sq Wave can play them loudly, but it cannot extract the same great sound from the K1000 like the ZDT, while Sq Wave XL is very nice with other normal headphones (like balanced HD600/800 or balanced/modded D2000).
My single ended HF-2, and balanced HD600/HD800 also sound quite good with the ZDT as well. The plan was to have the WA6 and GES in the living room rig for stats and dynamics, and the ZDT with Stax Pro transformer in the bedroom rig for stats and dynamics and K1000. But, the ZDT puts off so much heat that it may only be in the bedroom rig during the winter
All I had to do to pay for this was sell my Stax O2 Mk2 and APS re-cabled Edition 9. I have NO regrets at all.
