The planning and hoped for results with any of our mods will depend, to some hafler audio, on the underlying health of the original amp. Consider these helpful improvements, hafler audio. We have given short shrift to these amps so let us begin to remedy that. The kit prices are same, but some amps require more labor, i.

Author: Karsten Hein. Tag s : Power Amplifiers. There was a time when my good friend Luigi was bringing HiFi gear by our house for testing on a regular basis. And although there were lots of interesting discoveries to be made, somehow the devices did not strike a chord with us to the extent that we actually wanted to own them. One day, as I was climbing up the staircase from an evening teaching classes, I could hear music playing in the living room that sounded very realistic, even from a distance.

TA THX, rare more expensive Are there any underrated gems or sleepers in this list? How do these compare to the cheaper Adcoms, e. Or the older Brystons 2B, 4B? The ones made in China. Nothing against China, but these are their low cost crappy models. I think any of the P series are particularly well respected for studio use. John L Rice. I'm familiar with the DH and P series Haflers, as well as the Adcom and currently use a Bryston 3B, all of which I consider to be professional grade reference amplifiers suitable for studio monitoring. As for which is best, it's difficult to qualify an answer since not all amps were used on the same speakers, but I chose the 3B for its neutrality. All the others gave me the impression that they were sweetening the bottom end a bit, which may be incorrect because of using different speakers like I said.

Spatial representation is highly accurate and piano notes are flung deep into the room.

The Hafler circuit is a passive electronics circuit with the aim of getting derived surround sound or ambiophony from regular stereo recordings without using costly electronics. Such circuits are generally known as matrix decoders. The Dynaquad system works using similar principles. Named after its early proponent audio engineer David Hafler , the circuit exploits the high amount of stereo separation between Left and Right channels and sound phase. The rear channels will playback out of phase sounds, while the forward channels are unaffected. Using the circuit typically reduces stereo separation by only about 2 dB and the rear speakers are only required to reproduce a limited frequency range allowing them to be smaller and cheaper.

David Hafler February 7, — May 25, was an American audio engineer. He was best known for his work on an improved version of the Williamson amplifier using the ultra-linear circuit of Alan Blumlein. In , Hafler founded Acrosound with his colleague Herbert Keroes. This company was primarily in the business of designing and manufacturing transformers for tube amplifiers. Around this time Hafler and Keroes popularized the ultra-linear output-stage for audio amplifiers. However, the partnership did not last. In Hafler founded Dynaco with Ed Laurent. Hafler was instrumental in bringing affordable, high-quality audio kits to hobbyists, making his name a household word in the US audio community for many years.

Amazingly, its clear, three-dimensional sound is comparable to many amplifiers made today. McIntosh MC While the MC put the signature big blue meters in the market, many people consider this the greatest amplifier ever made. Released in as the MI for commercial applications, it eclipsed any amplifier of the day with an extraordinary watts per channel.

This can be most easily achieved by wiring two similar additional rear speakers in series between the live feeds positive terminals from the stereo amplifier. Technics by National Panasonic had a similar matrix decoder with two controls. I never heard of a Gately console, just their little suitcase mixers and mixer kits. Contents move to sidebar hide. Kit and installed version ready. The Elite version does a tremendous job. Consider these helpful improvements. The kit prices are same, but some amps require more labor, i. Life goes on. The units were acclaimed for their breakthrough sound quality and exceptional value, and are still highly prized today. For the American neurologist, see David A. Mike Rivers. Hafler Pro Amplifiers We have given short shrift to these amps so let us begin to remedy that.

As every audiophile knows, David Hafler is a hi-fi legend.

This is the finest mod we have to offer. I never heard of a Gately console, just their little suitcase mixers and mixer kits. You want all this at a price that is unmatched considering the top quality of parts and sound. Many US manufacturers don't go beyond sending a schematic and panel drawing to China and let them do the industrial engineering. How do these compare to the cheaper Adcoms, e. Schurter dual fuse holders allowing Euro 5 x 20mm AND 0. Whereas the Citation had caressed the listener, the Hafler had a straightness and insistence to it that was familiar to me from some Quad amplifiers. Gertrude Schwinger. The rear ambient sounds, applause, and coughs from the audience are sometimes received out of phase by the stereo microphones, while sounds from the musicians mostly are in synchronous phase. Philips had a similar circuit in their two-channel receivers. The one that designed the direct-coupled tube amps for electrostatics, which blew up and shot pieces of glass around the room? It depends on who designed what.
