Obviously you'll get lots of different opinions on what the problem is. However, the FIRST thing I always look at when I read these analog posts is how much output the cartridge has and how much gain the phono preamp provides.
As mentioned above by another poster, the Bellari gain is low: with the stock tube around 30 db. Your cartridge at 5 mV is looking for an ideal match with a phono pre around 36 db of gain. Sometimes you can get away with being 3-4 db short of gain. My experience when you get to being 5-7 or more db short is this: you can crank the volume up all you want and it will get louder but the music will still sound anemic, bland and totally lacking in dynamics. Kind of like listening through about 3 wet blankets.
My advice is this: check at vinyl asylum on another tube for the Bellari that might increase the gain a bit-I believe I've read somewhere that this is possible and probably won't cost an arm or a leg. Alternatively, try to borrow a phono stage suitable for MM/MI cartridges with 36 db. of gain. My guess is that you will be pleasantly surprised with what the correct amount of gain matched properly to your phono cartridge will do. Will it be perfect? Of course not, but at least you'll begin to hear what your equipment is capable of.
