Does it have enough volume when played through the receiver? 38db is not a lot of gain but you also get more gain from the receiver's preamp when the turntable is used with it. You won't get the advantage of the 7200's gain when using the tape outs. The best sound would be achieved by hooking the turntable directly to the computer. But you may not have enough output from the turntable's phono stage for that unless you get a higher output cartridge.
If you do not want to spend more money, you can use the preamp outs on your receiver if it has them. Then you would have more gain and any EQ that the receiver has. The disadvantage to this setup is that you don't get as pure a signal and there are more than one volume control in line.
If you happen to turn the volume up or down, it will change the level on your recording.
Another thing that you might want to check is if there is an input level setting on your computer for recording from outside devices. I think there is, look in the control panel.
