It's common for cd players to have more output voltage than phono stages. Actually, this is almost always true, which translates into cds being louder at lower volume than your TT. If the voltage from your phono preamp is too low, you'll hear more hiss and noise than you should. With vinyl, it's better to have plenty of gain than not enough.
Your Grado Gold has an output of 5 mV and needs at least 36 dB of phono gain to sound best. I'm using KAB's phono calculator to get this number. The Bellari is less than ideal in your system and is probably introducing quite a bit of noise. If you go with the Jolida JD9, it will grow with you if you upgrade your TT and cartridge. Of course, there are plenty of other phono stages to consider, but the JD9 is excellent for the price.
