all BS aside, I've yet to hear a better amp. my VMPS's are 4 ohm speakers and the krell will pick them up and through them across the room, all 160 lbs apiece. the power output of the two amps are identicle,about 325 wpc into 8 ohms,650 into 4ohms. the ksa 200 was only made for a short time before krell redesigned the case and heat sinks and called it a ksa 250. this leads to the only drawback to this amp, it is huge and weighs 125 lbs and runs hot enough to heat up a small room. the transformer is the size of a volley ball and the capacitors as big as beer cans. all manufacturers hype aside this is indicative of huge power reserves. what surprised me most about this amp was it's ability to run the VMPS's to a legit 120 db level without a hardening of the sound or muddying the bass. the sound of the ksa 200 is powerful but surprisingly delicate in the highs and midrange. I use a balanced krell pre amp to drive the ksa 200 which drives a pair of huge VMPS super towers R. I used that amp with mods for years without finding anything better. I'm an audiophile and have used many power amps going back to 1973 when I built my first dynakit, a stereo 410. I have used this massive power amp for 10 years without a hint of trouble. and like krell says don t judge on their first 15 minute, they need warm up time, after 1 or 2 ours of use, they are blooming, you don t want to turn it off. for sound accuracy it is very accurate, you can ear the sound with great dynamics, you can almost feel the sound decay from start to finish of every note from delicate to explosive, I don t see why all that bashing, maybe if your speaker sound bright, those amp are very reveiling, and lot s of details, I try them with small 2 way and for sure you cannot get all the satisfaction out of small monitor, because you need big speaker to get the full dynamics this amp can give you. my speaker are 4 ohm and amp don t run too hot, it can drive any load and she thrive driving difficult load. mine is a early version I think because it is rca only. Great amplifier, I use it to drive my front speaker, Danaudio studio monitors with Dynaudio drivers, in a 5.1 surround set up,very nice balance sound, image like crazy,bass is fenomenal, it is tight and deeeep.very quiet,as quiet as if it was off, not even a his.
