Author Topic: Hafler Amps, opinions? Oscar Neundorfer Master Film Handler Posts: 275 From: Senoia, GA Registered: May 2000 posted 09-27-2006 11:02 PM                        When I was at SMART, we used the HAFLER modules for MANY years. They were EXTREMELY reliable, sounded very good and could drive just about any load. Now they were not all that powerful at 120 W into 8 Ohms and 180 W into 4 Ohms, but unless you wanted digital at screaming levels, they would do the job. Of course, we were only using the modules. We built our own toroidal power transformer and used much better and larger filter caps than the Hafler amps. So, it is obviously not a direct comparison, but the amplifier modules themselves were quite good. Later we used the modules in our home theater amplifier which got very good reviews in Stereophile, Absolute Sound, and Widescreen Review magazines as well as several online audiophile sites. You can access these reviews at the bottom of this page: SMART Home Theater Amplifier 2X150VT Later, I re-designed the circuit board, added another pair of output transistors, and made it modular with gold-plated heavy duty header pins for plug-in use. This design was used in the SMART three channel home theater amplifier, which unfortunately never made it into production. Bottom line is that while the original Hafler amplifiers had their shortcomings, the SMART design using the Hafler modules was a significantly improved product of which we sold many thousands over the years. Many are still in use today.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 09-29-2006 03:37 PM                     we have many of the smart haffler amps in service with excellent results I smaller rooms the amount of power is not always in the gigawatt range with efficient speakers  |  IP: Logged
