I love the Sutherland Phono Blocks that I purchased. I am currently using an inexpensive cartridge (Denon 103R) and they put out amazing sound. To fully take of their abilities I have decided to buy a better cartridge, power cables. I will email you a review when I have had a chance to listen to everything after the break ins are all done. Even if nothing changes in it the best sounding phono preamp I have heard.
