Originally Posted by SteveM324 I've owned the K1000 for almost a year now but I had not heard it anywhere near its full potential until just this morning after reading some threads about amplification for the K1000's. For the last year I've been using either a Grace 901 or my RS Raptor to drive them. Most of the time I had been using the Raptor. My complaint with either of those amps with the K1000 was that it sounded too lean, sibilant and not enough bass. I tried many different tubes with the Raptor, the the Tungsol's were the warmest, but I was not completely satisfied. Well this morning I connected the K1000 (using the stock cable) to one of my speaker based amps, the Mark Levinson No. 383 integrated amp. This amp is 100 W/Ch into 8 ohms and 200 W/Ch into 4 ohms and its MSRP is $6500. Way, way too much amp, right? Wrong! The leaness and lack of bass is completely gone. These headphones take a lot of power to drive them well. The sound is full, warm, open and effortless. The bass is deeper than I imagined these phones were capable of. Those are adjectives I would never have used to describe the sound of the K1000's before I heard them through the Mark Levinson amp. The reason I say they take a lot of power is because I have to set the volume control on the ML amp to the same level as I do when driving my speakers (Revel M20's 87 dB efficiency). Up until this morning I was considering selling the K1000's but now that I've really heard them, no way would I sell them. Until this morning I would have ranked the K1000's behind my 650's and my K340's (both driven extremely well by the Raptor) but now the K1000's may become my favorite (only long term listening will tell). I'm not recommending that anyone go spend $6500 on an amp for the K1000's, my point is that it really takes a powerful high quality amp (tube or SS) to bring out the best in them. I may even try my Classe' CA400 power amp (400w/Ch into 8 ohms & 800 w/Ch into 4 ohms) with my CAT SL1 Ultimate preamp to drive them |

SpkK1000 Power 100100Watts Resistnce 8220Ohms Voltage 28148Volts Current 3.50.7Amps If so, can the answer be that because of the high restance of the K1ks, there is not much current reaching the phones??? |
