Yes you have to turn the volume up more than usual but being a analog pot the volume increases exponentially the more you turn it up so it has never run out of puff. The remote option is also a winner and is smooth and easy to get right. ![]() Please note that I have chosen to run this with an Icon Audio BA3 valve buffer which sorts out any issues with impedance miss match but works equally well without it. A small change in pot resistance or earthing makes or breaks the sound. I did a lot of research regarding passive Pre-Amps and even built one with a pot and switch box but nothing could prepare me for just how good this Icon Audio Pre sounded. People don't realize how critical the Pre-Amp is and that unless properly designed will alter gain unevenly over the frequency spectrum making some music sound amazing and others just flat and out of balance. This includes the QUAD 303 and all of the Leak valve amplifiers.Ģ6 February 2021 I bought this Passive Pre-Amp after many years of unhappy sound from traditional Pre-Amps after my beloved Yamaha died in a ball of flames after 35 years. It is a veryĪs a general guide it may be used with any power amp or mono blocks with 1v sensitivity or greater. Or by providing a monitoring circuit for your recording equipment as well as additional inputs. The Passive is very versatile and can also be used purely as a selector box with the volume wide open. This is the only way to hear the true sound of your power amplifier, with nothing added. There is no noise because there is no amplifier to make noise. There is no hum because it is perfectly screened. But as there is no such thing as a perfect amplifier, by default the Icon passive is considered perfect, as it has no flaws! This may sound conceited, but it is the basis of all their integrated amplifiers. Some years ago QUAD described the perfect amplifier as a piece of wire with gain. In which case you only need to control the volume, and switch the input. On the other hand your modern tuner, CD player, phono pre amp etc probably has enough output to drive your power amp(s) effectively, and you will probably be using relatively short (0.5 to 3m) leads. Its beauty is that it has no distortion or noise, therefore does not colour the sound, and the price is very affordable.Īside from tone controls and balance which thankfully most high quality pre amps have dispensed with, the principal reasons are:ġ, Voltage, gain where your 1 volt tuner output needs to drive a 1.5v power amp input.Ģ, Where the capacitance of very long connecting leads degrades the high frequency. Most CD/DVD, tuners etc already have enough voltage. Icon Audio's passive preamplifier is ideal for use with most power amplifiers. If you need any of these the Icon Passive R could help. Do you need more inputs, volume control and remote control?
