hi.i have a musical fidelity a3cr preamplifier in a second system. i purchsed it 10 years ago and has been reliable without any problems whatsoever. recently i added it a current pass labs amp - to judge if a preamplifier was beneficial as opposed to cd diresct- and it certainly did something good to the sound. even though its now quite old and can be had for little money, its still good. i recall there being very little difference between the two when i listened at a dealers years back. i went for the cheaper one. my musical fidelity a3 power amps, preamplifier and cd player have performed flawlesly for the pass 10 years. that says something about the brand. for my first serious hi fi set up, it gave me great pleasure.
