I am using the mike input on my Laptop computer and I am not getting good recordings. I purchased a preamp and that has helped the output when I pay through my speakers but not the recorded music. the music is low nad echos and sound like it is coming from about 200 yards inside a cave, it deadens out at points. any suggestions would be greatly appreciated. I use the Cassette ez part of the SW and it worked great, but I am currently very disappointed witht he vinyl. IF it is user error plase advise what I can do..
