I urge you guys to read an elementary book on audio electronics. You might thereby learn to understand why a preamp (for one example) exhibits disappointing bass response compared to another. In this case, it might simply be a matter of the value of the output coupling capacitor. If so, the problem can be fixed by installing a different capacitor of higher value. Also one needs to pay attention to the input impedance of the device that the preamplifier is driving. These factors can make all the difference in the world, And they can be fixed without spending thousands of dollars on an entirely new device.
Interesting, maybe i will crack it up one day to see what's inside.
This italian phono stage only need more bass (imo).
