Would increasing the gain in the amp give more weight to the sound? Any negatives?

I have an integrated amp with passive preamp section and I feel that the sound is not full-bodied enough. The separate phono stage has 42db of gain and I use MM cartridge. When I play cassette deck, the sound is just right in this respect.
I talked to the designer, and he said that increasing the gain is theoretically possible, though time consuming.
And if I do want to increase the gain - by how much? The amp is 120 watt/ch/8ohm, speakers are 89db efficient, 8ohm.

I have not tried it myself, but, I know that some people increase the sense of body and weight by inserting a 1:1 "repeating" transformer into the line level signal (e.g., between the phonostage and linestage, between CD player and linestage, or between the linestage and the amplifier.  An example of a really good line level transformer is the old Western Electric 111c and 119c transformer.  This is discussed on some DIY sites, such as this:
