Paul Klipsch was right - What the world needs is a good 5 watt amplifier
For those who are questioning whether a low power high quality amp would be able to properly drive any speakers I've recorded a short video demonstrating very high SPL level from a speakers with average sensitivity. The video is of very low audio and video quality as its recorded from my smartphone. However, the microphone used for measuring the sound pressure is MiniDSP UMIK-1 and the software used is REW (Room EQ Wizard). During the tests the amplifier didn't show any hint of stress of distortion
The speakers used in this video are Sonus Faber Olympica II and the integrated amplifier is Pass Labs INT-25. According to some third party reviews the Olympica's are thought load for the partnering amplifier as their sensitivity is averagely rated (88db) and the impedance curve drops down to 3 ohms in the bass region with a estimated EPDR (the point where the impedance curve is intersecting with the phase angle) of 1.6 ohms. The pass labs is rated at 25wpc @ 8omh and is said to be stable down to 1 ohm doubling its power at 4 and 2 ohms. According to the manual it can deliver 200wpc @ 1ohm before the protection circuit is activated.
So, the point of the video is to show that the Pass with its poorly rated power (25wpc) can drive even demanding speakers to insanely loud levels without any sound degradation.
@divertiti The video is recorded with my 70$ smartphone (huawei). Don’t you think Wilson Chronosonic driven by D’Agoustino Monoblocks will sound the same on my phone? Don’t you? Please don’t waste our time with comments like this ... PLEASE |
You are so close to self awareness it's actually painful. You posted a video measuring an amplifier using REW and an SPL read out making claims about distortion and sound quality, on a $70 cell phone non-the-less. "waste our time" is exactly the right phrase to describe this thread. |
105db or higher for 5 watt to sound sufficently good enough at decent volume level and even then it depends on the room and seating distance. These amps struggle with bass.
Personally i would not touch flea watt amps unless my speaker is 110db or higher in sensitivity and room is optimised whilst at the same time im not sitting to far away. |
