    Questions about Hafler DH-110 connections.

    I got my first hafler components a few months ago, a DH-220 amp and DH-110 preamp. I got these in a trade, and neither worked well. I took them both in for service and just got them back last week. I'm not experienced with hafler products and I have a couple of questions regarding the...

    Bridging a Hafler DH-220

    Hey folks ... I recently picked up a couple of Hafler DH-220s to play with. I was looking at the manual for the DH-222 bridging kit, which seems absurdly simple. It got me to wondering if it's feasible to bridge this amp using an external apparatus. Initial internet searches have turned up...

    Upgrading a Hafler DH-101

    The DH-101 was Hafler’s first preamp after he founded Hafler. These were available from the late 70’s to the early 80’s. And they are still around – mostly in unmolested state. Therein lies the problem. Approaching 40 years old, the assumption is that they are all providing the same sound as...

    Upgrading a Hafler DH110

    The DH-110 replaced Hafler’s first preamp, the DH-101, and was produced from the early 1980’s to the early 1990’s. I picked up this unit and decided to look inside and upgrade it. This unit has everything. A headphone amp that’s not very loud. A muting circuit to prevent downstream thumps that...

    Hafler DH-200 refurb questions

    I built a DH-220 back in the day and now regret having sold it (and cheap, too). So I picked up a working DH-200 and plan to do some mild refurb: New electrolytics, new bridge rectifier, inrush current limiter. Bumping up the voltage on the 'lytics and upping C16/17 to 18,000uF 75v. So far so...

    Upgrading a Hafler DH-100

    I bought this DH100 to digitize my LPs. I needed a phono stage and the ability to control the output to my Analog-to-digital converter. It worked for a while but I wasn’t happy with the sound. I looked into the DH100 and discovered it was a series 1. And there was a series 2. Could this be the...

    Hafler se-120 Bias

    Greetings- I have a Hafler SE-120 amplifier and one side of the amp gets hot even when at Idle. I suspected that the bias needed adjusting. The manual states that the bias should be set at 100ma so I measured the settings according to the service manual and the left channel was spot on at 100ma...

    Used Affordable Power Amp Suggestions

    Hi All, In tweaking with my McIntosh MA-6100, one thought I had was to try using it as a power amp as it is just missing "something". So, I thought hooking it up to something with some digital ins might not be a bad thing either. The eBay Gods were good to me, and I was able to reasonably...

    Currently running my KEF Q100s off of a Hafler DH200 but interested in some possible options out there. Anyone familiar with the NAD 7400? Would this be a nice pair for the KEFs? Worth trying out? Kelley

    Hafler DH 500 common ground?

    Good evening! I have a Hafler DH 500 that I'm selling on anther site. An interested buyer has asked if his Polk speakers, which require a common ground, will work with this amp. Does anyone know the answer to this? Why would speakers need a common ground?

    Hafler DH200 and KefQ100

    Howdy, I recently picked up a pair of KEFQ100 and I'm powering them with a Hafler DH200. I was really impressed with the speakers in the show room but haven't liked them as much at home or maybe I am not liking the amp as much. 1. Any ideas on a better amp to match the KEFs? 2. Any speakers...

    Hafler XL-280 versus "professional" amplifiers

    I like my Hafler a lot, but my Maggies (MMG) could use a tad more juice. How do the professional amps like the Crown XLS series, Yamaha P series, and QSC pro amps work with a 2 channel music only system? (open to other as well, those just seem to be popular) Are they going to ravage my Halfer in...

    Hafler dh-200 VS Hafler dh-120

    What sounds better, Hafler dh-200 or Hafler dh-120? I own both and already have an opinion on this subject but I was wondering what everyone else thought. Many people disagree with my findings.
