    An Absolute Gem

    In a world where simple switching preamps are suddenly hard to find, this thing is a gem. It features normal pre-digital-era style input switching, tape monitoring (useful for any recording device or as an effect send/receive), a great-sounding equal loudness control that's independent of the volume setting and a great-sounding 3-way tone control EQ. I run through a powerful DSP (which does my EQ and crossovers with programmed FIR filters) into huge power amps and speakers in a triamplified system. This is no car stereo or desktop hi-fi. If I switch my ADC to accept CD input from (1) analog routed through this preamp to (2) direct digital into my DSP, I have to strain to hear any difference and doubt I could pass a blindfold test. I bought it hoping only to find something with a workable equal-loudness control. That is not only workable but is designed correctly (simple bass boost with some high treble boost, i.e. not an F-M curve but the difference between them) and sounds wonderful when set properly. It has simply become part of my system, the main 'mixer' for my analog sources. At 5x the money I couldn't be happier with it.

    A solid purchase

    If you are into audiophile but budget restricted, this pyramid pre-amp will satisfy the most finicky enthusiast. With features like trebble, bass and midrange you can adjust your music to your individual taste and on top of that the adjustable loudness button lets you fine tune the amount of power between your existing amplifier and the Pyramid PR2500. Whether you are into classical, country, Jazz or whatever style, I"m confident this pre-amp will do the trick at a very affordable price.


    if volume turn on all very distors and connect tape or cd but on the tuner always you heard on tape monitor
