I've had DH100s since their debut about twenty years ago. I've used them as separate units with one amp driving the high section of Maggies, and the other amp driving the low section. I've used them bridged and I've used one to drive KEFs. This is the classic Hafler amplifier. With a few capaciter modifications, I would put it against Levinson, or anybody else. The Hafler DH100 is bulletproof. One that I have has been powered up for over fifteen years. No better bargain can be had in the used marketplace. Magic......with a good source......Black magic.
