Music_Smurf Posted December 19, 2002 Share Posted December 19, 2002 There is much talk on this forum about how Klipsch speakers sound good with Parasound amplifiers. Based on this talk, I am looking into getting a Parasound amplifier. I notice Parasound makes MOSFET and transitor amplifiers. What is the difference in sound quality between the two, and which one is more compatable with Klipsch? Quote Link to comment Share on other sites More sharing options...
jdm56 Posted December 19, 2002 Share Posted December 19, 2002 Mos-fets ARE transistors: "Metal Oxide Semiconductor-Field Effect Transistor", or something like that. The popular conception is that they sound more tube-like than conventional bi-polar transistors; A conception I tend to hold also. But I couldn't begin to tell you why they do. I do think that is why they make a good match with klipsch speakers. The mos-fet smoothness tends to ameliorate some of the klipsch tendency towards a bright, forward sound. I use a mos-fet integrated amp (humble Sony ES) with klipschorns, and just love the results. Quote Link to comment Share on other sites More sharing options...
leok Posted December 19, 2002 Share Posted December 19, 2002 A MOSFET is a high gain, not exactly linear, but not exponential, device. A bipolar transistor is a high gain, exponential device. With a bipolar transistor, a designer must deal with feedback and nonlinearity. With a MOSFET, a designer must deal with feedback. Bipolar - 2 problems. MOSFET - 1 problem. leok Quote Link to comment Share on other sites More sharing options...
Randy Bey Posted December 19, 2002 Share Posted December 19, 2002 I once had an old Sony integrated with JFET output devices; which, as I understand it, has been replaced by MOSFET designs. It was low power (who cares?) but boy it sounded sweet. Years after selling it I still kick myself for doing so. Tubelike? I don't know. Never compared it to tubes.

Deang Posted December 19, 2002 Share Posted December 19, 2002 Before you jump into Parasound, you might give serious consideration to some of the new Richard Marsh designs. http://www.marshsounddesign.com/ Quote Link to comment Share on other sites More sharing options...
