Purchased this to bring my albums back to life and to be able to use my old Pioneer PL X300 with my Harman Kardon receiver. Matched with some good quality RCA Audio cables and man I can not believe the sound!! I swear my albums sound better than there cd counterparts. Anyways the Preamp works perfectly, seems very well built and at a very good price. I am very happy with my purchase and can highly recommend it. I actually needed to contact them due to a sound issue with my left channel.  He had me shut off all the DSP additives on my Harman Kardon receiver and BAM!!! perfection!!! The Doors Alive She Cried never sounded so good!!!!!  Make sure to set your receiver to 2 Channel stereo all DSP off.
