Hafler audio

The planning and hoped for results with any of our mods will depend, to some degree, on the underlying health of the original amp, hafler audio. Consider these helpful improvements. We have given short shrift to these amps so let us begin to hafler audio 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. Whatever this is, I was thinking to myself taking the last few steps, this is going stay.

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. In the s Hafler promoted "passive pseudo- quadraphonics ", an inexpensive method of recreating ambient sounds at the rear from ordinary stereophonic recordings. The crosstalk or loss of stereo separation in the front speakers was generally less than 2 dB , while the rear sound level in a typical recorded live performance was about 7 dB below the front, but clearly audible. The Dynaco QD-1 Quadaptor was based on this idea, adding a variable resistor to control the volume of the rear speakers. This passive method worked fairly well compared to the matrix decoders of the period, which attempted to reconstruct a surround sound field from a two channel recording.

Important thought!

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.

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. The consumer version, MC established McIntosh as the premier audio company of the day. Phase Linear It was and Bob Carver saw the future and brought to market a product that would set the stage for a new audio segment—affordable, mass-market, high-performance audio. Rock bands put dry ice on stacks of these legendary watt per channel amps to cool them down. The Series One is the one to have.

As every audiophile knows, David Hafler is a hi-fi legend. In he founded Dynaco and soon became a household name. The Dynaco ST, one of the best-selling amplifiers of all time it sold more than , units in its lifespan —and considered one of the greatest classic amps—needs no introduction. Ditto the beloved Dyna-Kits, affordable ready-to-assemble kits for building preamplifiers and power amps that also proved very popular, even ubiquitous, during the s and 60s.

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. Report message. My point was that the Jim Strickland amps probably aren't as good as the David Hafler amps. Read Edit View history. See versions here. The newer Transnovas aren't really Haflers at all. 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. Toggle limited content width. The class-A portion of the amplifier was increased in the process, which has a positive impact on sound and leads to greater heat dispersion. This is the type of quad setup used by Seeburg jukeboxes that had quadraphonic sound. Kit is coming, uh a little slowly. The rear sound level in a live performance recorded in stereo is reproduced about 7 dB below the front level, but clearly audible. Elliott Sound Products. Having listened to the Hafler P, I'd say it's at least as good as anything I've heard from the early Hafler amps. Quadraphonic sound.

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.

Ultra adds near complete premium audio grade resistors array, superb front-end power supply caps. Kit and installed version ready. Hafler DH Quadraphonic sound. Nothing against China, but these are their low cost crappy models. Svenska HiFi Institutet 73 : 6— See prices below. David Hafler February 7, — May 25, was an American audio engineer. The concert hall sound means the listener hears all the instruments from the front, whereas the rear channels are mainly used to give the listener the acoustic effect of sitting in a concert hall. Radial planned to re-launch the Hafler brand of high-fidelity audio products. University of Pennsylvania. Download as PDF Printable version. Scroll below for PA-7 details.
