I have owned McIntosh MC-240, McIntosh Mc-275, Spectral DM-200, NRG (forget the model number), Marantz 7B, Leak Stereo 20, Audio Research D-76, D-76A, Krell FPB-200, Edge M8M, Luminance Audio (big mistake), McIntosh MC-402. Have been an audio-nut since 1958. About 6 months ago I tried a Sanders Sound Systems Magtech amp (they have a 30 day trial period) and I was absolutely amazed at the sound of this amp. I liked it so well that I bought the companion Slim Line Stage preamp. I drive the Duntech Sovereigns and I have never been as satisfied in my long audio career as I am now. I know that I will be ridiculed by some of the audiogon experts, but I have bought my last amp and preamp and that's the gospel. IMHO the Sanders equipment is the best kept secret in the audio world. And it is also fairly priced. Not the outrageous prices charged by many manufacturers and it comes with a lifetime warranty. Enjoy the music friends.
